Abstract:
The collection contains 69 black and white photographs of California Native
Americans, apparently the Yokut of the San Joaquin Valley, Miwok of Yosemite,
and the Pomo of the Clear Lake Basin - with captions indicating activities such
as arrow making, basket making, fishing, hunting, and village life. Used at one
point as educational packets, these appear to be relatively recent photos, not
19th century or early 20th century ethnographic images.

Abstract:
Construction and operation of the English Ridge Reservoir, as proposed by the
U.S. Bureau of Reclamation, together with the naturally available flows from
the remaining drainage area, will provide flows in the Eel River downstream
from English Ridge Reservoir that will be sufficient to maintain adequate water
quality for the fishery and other beneficial uses of the river's waters. The
planned diversion of stored water through Clear Lake will enhance the water
quality of Clear Lake, and thereby improve its aesthetic and recreational
values. (Modified author abstract)

Abstract:
The supplement to the final environmental statement for the Indian Valley
Project of the Yolo County Flood Control and Water Conservation District
addresses the question of whether or not the operation of the Indian Valley
Project will adversely affect the water surface levels of Clear Lake in Lake
County, California. The supplement concludes that the operation of the Indian
Valley Dam and Reservoir will not affect the water surface levels of Clear
Lake.

Abstract:
Fish and Game planted Florida-strain bass for three years, 1969, 1970, and
1971, in an attempt to create a trophy-size population of largemouth bass in
Clear Lake. The southern bass live longer, grow bigger, and are harder to catch
than the northern strain of bass which were originally placed in the lake prior
to 1900. The record fish was the second known bass weighing more than 10 pounds
to be taken in the lake this summer.

Abstract:
In September of 1998, the United States Forest Service, Modoc National Forest,
and the United States Fish and Wildlife Service, Yreka Fish and Wildlife
Office, entered into an interagency agreement to implement and administer
watershed improvement and restoration within the Lost River/Clear Lake
watershed of northern California. Fifteen thousand dollars of funding for this
project was provided by a 319(h) grant awarded through the North Coast Water
Quality Control Board of the State of California. The program agreement
recognizes that livestock grazing is a major resource use impacting watershed
conditions and that proper grazing practices are key to watershed maintenance,
improvement and restoration. Therefore, a project designed to facilitate proper
use of key streamside habitats by livestock was implemented through the
agreement. The project specifically provides for the construction of
approximately 10 miles of riparian fencing to control timing, intensity, and
duration of cattle grazing along Lost River and Rock Creek within the Clear
Lake grazing allotment of the Modoc National Forest.

Abstract:
This report summarizes the findings of an extensive treatability study of three
stabilization technologies for mercury immobilization on materials collected
from the Sulfur Bank Mercury Mine (SBMM), located north of San Francisco, in
Lake County, California. The SBMM site is believed to be contaminating the
adjacent Clear Lake environment with mercury derived from historic mining practices
at the site. The study was conducted as a joint effort between EPA’s Superfund
Innovative Technology Evaluation (SITE) Program and the Mine Waste Technology
Program (MWTP). Two mercury contaminated materials were selected for treatment
by three types of stabilization technologies.
The
purpose of the study was to determine the effectiveness of the three
stabilization technologies for immobilizing mercury in the waste rock materials
and therefore reducing leachable mobile mercury in the effluent. Several
mercury-bearing materials from the site were considered for testing. A material
with high levels of leachable mercury was selected as the primary target of the
study, and is referred to as “Mercury Ore”. As a secondary objective, treatment
effectiveness was evaluated on material that was lower in mercury
concentration, but present in large quantities and is referred to as “Waste
Rock”.
Three
stabilization technologies were evaluated as part of this study: (1) a Silica
Micro Encapsulation (SME) process developed by Klean Earth Environmental
Company (KEECO), (2) an inorganic sulfide stabilization technology (ENTHRALL®)
developed by E&C Williams, and (3) a generic phosphate treatment.
The
primary objective of this study was to determine the effectiveness of the three
stabilization technologies (silica encapsulation, phosphate, and sulfide) in
reducing the quantity of leachable mercury from SBMM material. Waste material
evaluated in this study consisted of “mercury ore” from the south white gate
pile and “waste rock” from the north yellow pile. The mercury ore was the
primary test material due to its demonstrated ability to produce consistent and
detectable levels of leachable mercury. The waste rock was included because it
is a common material at the site, even though it yields lower levels of
leachable mercury. In order to evaluate the performance of the three
technologies, the leachable and mobile mercury (defined as the mercury in the
<25μ filtered leachate fraction) from control columns receiving no treatment
was compared to the leachable and mobile mercury in the treatment columns.
Specifically, the objective was to achieve a 90% reduction in the total mass of
mercury leached from each treatment relative to the control over a 12-week
continuous column leaching study.
Leachability
results from the no treatment control columns revealed that the predominant
source of leachable mercury was found in the particulate fraction, i.e.
approximately 96%. The phosphate treatment dramatically increased the levels of
both the particulate and dissolved fractions (<0.45μm) over the course
of the 12-week study. The dramatic rise in leachable mercury brought about by
the phosphate treatment invalidates its utility as a remedial alternative for
materials at the SBMM site. The E&C William’s ENTHRALL® Technology did not
appear to be effective in reducing the levels of mobile mercury in the mercury
ore column tests. The total mass of mercury in both the particulate and
dissolved fractions are statistically similar to the control. KEECO’s Silica
Micro Encapsulation Technology applied both in situ and ex situ, was effective
in reducing mobile mercury (<25 μm) very close to the 90% reduction
goal of the study. However, there was a significant increase in the mass
mercury levels in the dissolved fraction (<0.45μm). The in situ
applications exhibited a 198% increase relative to the control, and the ex situ
exhibited a 238% increase.

Abstract:
California's only native centrarchid is virtually nonexistent in its native
habitat: the waters of the Central Valley, the Clear Lake basin, and Pajaro and
Salinas rivers. It has been introduced and successfully established in a number
of artificial environments and natural waters outside its native range; it is
in no danger of becoming extinct. The history of its decline and transplanting
is traced.

Abstract:
Clear Lake occupies a structural depression in the northern California Coast
Ranges at an elevation of 404 meters. Eight sediment cores were taken from the
lake in 1973 and the palynology of cores CL-73-4 and CL-73-7 are reported. The
former is 115 meters long, and is interpreted to cover the entire last glacial
cycle; the latter is 27.5 meters long and covers at least the last 40,000
radiocarbon years. The pollen records of both cores are dominated by three
pollen types (oak, pine, and TCT (Taxodiaceae, Cupressaceae, and Taxaceae) that
together account for between 75 and 99 percent of the pollen in each sample.
The present pollen rain around Clear Lake is dominated by oak pollen. During
the cooler parts of the last glacial cycle , oak pollen influx to the sediments
of Clear Lake was largely or entirely replaced by coniferous pollen (mostly
pine and TCT) in response to vertical migration of vegetation belts caused by
climatic changes. Pollen data were reduced using a Q-mode factor analysis. Five
factors were defined that account for more than 98 percent of the variance.
Zoning of the pollen diagrams was accomplished using an iterative program. The
21 pollen zones of core CL-73-4 are used to propose a series of informal
climatic units that include the time interval from the penultimate glaciation
to the present. The major units proposed, from oldest to youngest, are: (1)
Tsabal cryomer, (2) Konocti thermomer, (3) Pomo cryomer, and (4) Tuleyome
thermomer (Holocene). The record in the sediments of algae with acid-resistant
remains indicates that lake productivity was relatively high during warm
intervals in the past, and that overall productivity increased as the lake
became shallower and its thermal inertia decreased. The lake waters were
probably transparent during the cooler parts of the last glacial cycle, but
Clear Lake has probably not been as clear a lake during the Holocene. (See also

Abstract:
Pollen analysis of a 115-m sediment core from Clear Lake, Lake County,
California, provides a climatic record that is continuous for the past 130,000
yr. The pollen record reflects migrations of the tree species of the California
Coast Ranges in response to the climatic changes of the last glacial cycle.
During interglacials, the Clear Lake pollen rain was dominated by Quercus (oak)
pollen. During cooler periods, oak pollen was replaced by pollen of coniferous
species. The curve for Quercus pollen strongly resembles and is used to
correlate with both deep-sea oxygen-isotope curves and the climatic record from
certain European pollen studies.

Title: Temperature and Precipitation Estimates through the Last Glacial Cycle
from Clear Lake, California, Pollen Data
Abstract:
Modern pollen surface samples from six lake and marsh sites in the northern
California Coast Ranges establish a linear relation between elevation and the
oakl(oak + pine) pollen ratio. Modern temperature and precipitation lapse rates
were used to convert variations in the pollen ratio into temperature and
precipitation changes. Pollen data from two cores from Clear Lake, Lake County,
California, spanning the past 40,000 and 130,000 years were used to estimate
temperature and precipitation changes through the last full glacial cycle. The
maximum glacial cooling is estimated to be 7 to 8C; the last full interglacial
period was about 1.5C warmer than the Holocene, and a mid-Holocene interval was
warmer than the present. The estimated precipitation changes are probably less
reliable than the estimated temperature changes.

Abstract:
Methyl parathion was applied to Clear Lake at a rate of 3.3 ppb for control of
Chaoborus astictopus Dyar & Shannon. Three treatments at 20-day intervals
had no lasting impact on zooplankton. Recovery to near or above pretreatment
numbers was rapid for the organisms examined., including copepod nauplii,
Diaptomus franciscanus Lilljeborg, Cyclops sp., Mesocyclops spp., Daphnia spp.,
Bosmina longirostris (O.F. Muller), Diaphanosoma brachyurum (Lieven) and
Ceriodaphnia reticulate (Jurine).
No
residues were detected in lake sediments. Highest residues in water were found
8 and 24 hr after the treatments, varying from 0.5-5.4 ppb, and generally
declining after each treatment. However, generally larger residues were found
with each successive treatment. Residues in bluegill sunfish, Lepomis
macrochirus Rafinesque, exposed to the treatments in live cars, varied from
11-110 ppb. A significant correlation was found between the methyl parathion
levels in fish and water collected simultaneously.

Abstract:
The environmental impacts of mercury (Hg) contamination from gold, silver and mercury
mining in the western United States is actively being researched by a diverse
consortium of scientists including the UC Davis (UCD) mercury group and the
California Bay Delta Authority. Previously the atmospheric deposition of Hg,
primarily from power generating industries, had been the focus of studies on
the environmental impacts and distribution of Hg. However, in the western
region of the United States, the signal from atmospheric deposition of Hg is
frequently overwhelmed by Hg contamination from mining activities. The
California Coast Range in general, and in particular the Clear Lake and Cache
Creek watersheds (Fig. 1), are major sources of Hg contamination. The Coast
Range of California contains over 300 previously active mines that were responsible
for nearly ninety percent of the Hg produced in the United States between
1850-1980 (Suchanek et a/., 1997). Among the most productive were mines in the
Clear Lake and Cache Creek watersheds. The Sulphur Bank Mercury Mine (SBMM),
located on the banks of Clear Lake, CA, produced ca. 5,000 tons of Hg, and
mines in the Cache Creek watershed produced ca. 7,600 tons equaling more than
twelve percent of all California production (Slotton, 1995). Further
exacerbating Hg contamination within California" and contributing to an
ongoing problem, was the transportation from the Coast Range to the Sierra
Nevada Mountains of Hg that was used in gold and silver mining operations. Some
of the original Hg mined in the Coast Range continues to contaminate Clear Lake
and Cache Creek and to be transported downstream to the San Francisco Bay-Delta
where it is reunited with Hg that was transported to the Sierras.

Abstract:
Introduction
Often
called the "bass capital of the West," Clear Lake, Lake County
supports one of the best warmwater fisheries in California. The record angler
caught largemouth bass Micropterus salmoides is 17.52 pounds and was caught
February 1990. The catch broke the seven-week record-sized fish of 15.32
pounds. In 1969, Clear Lake supported 340,000 angler-days of effort and
produced a gamefish yield of 34.7 Kg/ha (31 lb/acre) (Puckett 1972); one can
only surmise that, with the dramatic population increase since 1969 in nearby
urban areas, the lake has seen a likewise increase in the number of angler days
of effort. Proper management is crucial in the face of this kind of pressure in
order to maintain and enhance the Clear Lake fishery.

Abstract:
This document presents information on the management of fisheries at Clear
Lake. A review of the past and present biological and social information
develop the environmental setting and enable logical fishery management
recommendations to be made. The fisheries action plan utilizes background
information to suggest ways to implement and evaluate management recommendations
with quantifiable milestones. Where more information is needed before
recommendations can be made, the action plan identifies areas that need more
attention and suggests a design for assessing the situation. The fisheries
management plan is an evolving document that reflects upon the past,
illuminates current issues, and focuses strategies for the future. This
management plan was developed to meet the goals and objectives of the
California Department of Fish and Game, fishery managers, and the desires of
the angling public.

Abstract:
Mercury pollution presents a globally significant threat to human and ecosystem
health. An important transformation in the mercury cycle is the conversion of
inorganic mercury to methylmercury, a toxic substance that negatively affects
neurological function and bioaccumulates in food chains. This transformation is
primarily bacterially mediated, and sulfate-reducing bacteria (SRB) have been
specifically implicated as key mercury methylators in lake and estuarine
sediments. This study used phospholipid fatty acid (PLFA) analysis to
investigate sediment microbial community composition at four abandoned mercury
mine-impacted sites in the California Coast Range: the Abbott, Reed, Sulphur
Bank, and Mt. Diablo mines. Differences in watershed and hydrology among these
sites were related to differences in microbial community composition. The
Abbott and Sulphur Bank mines had the highest levels of methylmercury. Floc (a
type of precipitate that forms when acid mine drainage contacts lake or river
water) and sediment samples differed in terms of several important
environmental variables and microbial community composition, but did not have
statistically different methylmercury concentrations. Quantification of PLFA
biomarkers for SRB (10Mel6:0 for Desulfobacter and i17:1 for Desulfovibrio)
revealed that Desulfobacter and Desulfovibrio organisms made up higher
percentages of overall microbial biomass at the Sulphur Bank and Mt. Diablo
mines than at the Abbott and Reed mines. Correlations between these SRB
biomarker fatty acids and methylmercury concentrations suggest that
Desulfobacter and Desulfovibrio organisms may contribute to methylmercury
production in the Abbott, Reed, and Sulphur Bank mines but may not be important
contributors to methylmercury in the Mt. Diablo Mine.

Abstract:
The results of amino acid geochemistry are reported with application to
deochronology in core 4 sediments of Clear Lake (California). Aspartic acid and
alanine were considered in detail to clarify uncertainties in correlations of
ash beds and pollen spectra in lacustrine sediment. Relative concentrations of
aspartic acid decreased with depth, probably due to diagenesis and to preferential
adsorption and hydrolysis in clay. Alanine increased with depth, probably
because of the generation of alanine during diagenesis of other amino acids.
When age assessment is based on alanine, results support a time-depth curve
obtained from oak pollen and oxygen isotopes over a span of about 130,000
years. (Small-FRC)

Abstract:
The biology of the prickly sculpin was investigated in Clear Lake, Lake County,
California in order to determine how it has persisted in the face of
introductions of numerous exotic species when most other native species have
declined in abundance or have become extinct. Sculpins over 15 mm SL inhabited
all types of benthic habitats in the lake, while post-larval sculpins were
pelagic when the postlarvae of exotic species were absent. The feeding ecology
of sculpins was distinct from the other fishes in the lake in that they fed
largely on amphipods and chironomid midge larvae regardless of the time of
year, time of day, or habitat. Sculpins were uncommon in the stomach of
piscivorous fishes, except juvenile largemouth bass (Micropterus salmoides ).
It is concluded that prickly sculpin have persisted in Clear Lake in part
because they are ecologically distinct from the exotic species and are not
preyed upon by them to any great extent, and in part because they have managed
to survive other man-related perturbations of this ecosystem.

Abstract:
Clear Lake, California, is one of the major recreational areas of the West
Coast. The economics of Lake County, of which Clear Lake is a part, is
primarily based upon the recreational attraction that is created by Clear Lake.
However, Clear Lake is inhabited by a small white non- biting gnat commonly
called the Clear Lake gnat (Chaoborus astictopus D. and S.). This bothersome
gnat has, when its numbers become too great, created a tre- mendous adverse
economic effect upon the County. Lindquist (1942, 1943, 1946, 1951), Roth
(1948), and several other entomologists (Herms 1937, Deonier 1943, Walker 1949)
spent several years in studying this gnat and developing a method of
controlling it. As a result of this work a method of control was developed, and
in Sep- tember 1949 the Lake was chemically treated with 14,000 gallons of a
TDE formulation. The treatment was tre- mendously successful and Clear Lake's
large resort busi- ness once more prospered.
For
almost 2 years no larvae of the Clear Lake gnat were found in Clear Lake. In
July 1951, however, they were again collected by means of a plankton net. From
that date on the population steadily increased until the gnat was once more
affecting the county's resort business, and a second control measure was
carried out in Septem- ber 1954.

Abstract:
Flight feathers from six bird species at Clear Lake, CA were analyzed to
determine the extent and distribution of mercury contamination from an
abandoned mercury mine and associated levels of 14 other elements. Feather
samples were collected from adult and juvenile osprey (Pandion haliaetus),
including juvenile osprey from three additional comparison sites; adult western
grebes (Aechmophorus occidentalis); adult great blue herons (Ardea herodias);
adult mallards (Anas platyrhynchos); adult turkey vultures (Cathartes aura);
and juvenile double-crested cormorants (Phalacrocorax auritus). Samples were
analyzed by a multielemental x-ray fluorescence method. The osprey from Clear
Lake showed significantly elevated mercury concentrations relative to the
comparison sites, Different species at Clear Lake had different mercury
concentrations based on trophic status; osprey exhibited the highest mercury
concentrations and the mallards showed the lowest, Lastly, we quantified
differences in elemental concentrations, including mercury, between adult and
juvenile osprey from Clear Lake. Elements known to be nutrients, such as sulfur
and zinc, did not vary significantly among species or sites. Reproductive
success of osprey at Clear Lake was monitored from 1992 to 1996 to determine if
osprey reproduction was depressed. During this five-year period, the breeding
population grew from 10 to 20 nesting pairs and the average reproductive rate
was 1.4 fledglings per nesting attempt. Although the osprey showed the highest
mercury levels of any species sampled, their reproduction does not appear to be
depressed.

Title: Persistence and Metabolism of Tde in California Clear Lake Fish

Abstract:
Clear Lake is a naturally occurring lake located in northern California in the
inner coastal range of mountains. It is shallow (mean depth of 8 meters), has a
surface area of approximately 42,000 acres and shows no thermal stratification.
On three occasions in 1949, 1954, and 1957 a total of over 120,000 ibs. of TDE
[l,l,-dichloro-2,2-bis-(chlorophenyl)- ethane] was applied to control the
substantial population of Clear Lake gnats (Chaoboras astictopus) . A second
and indirect source of additional contamination is the possible run off from
numerous neighboring orchards (pears, almond, and walnut) and grape vineyards
into creeks and streams feeding Clear Lake itself. In spite of the
approximately 500,000 ibs of DDT applied agriculturally during 1949-1964, the
observed residue levels in the lake proper does not indicate that this route of
contamination was of any major proportions (RUDD and HERMAN 1972, and HERMAN et
al. 1969). Additionally, these authors reported residue levels of TDE and
isomers in the top 5 inches of sediment ranged from 0.05 ppm to 1.0 ppm. This
TDE in the bottom sediments of the lake infers that bottom feeding species would
probably suffer from greater exposure to such high levels of TDE.

Title: Food web biodiversity, patterns and interactions in complex natural
ecosystems
Abstract:
Food webs for three California lakes (Tahoe, Castle, Clear) have been assembled
with some of the most detailed and complete data available to date. With this
information we have constructed complete descriptive webs, which include all
species, and functional webs, which include the abundant and other important
species. These webs include up to 794 species in five major categories: algae,
macrophytes, microheterotrophs, invertebrates, and fishes. There are clear and
signi ficnnt departures of the California lake food webs from earl ier generalizations
about trophic architecture and Iinks which were based on smaller and less
complete webs. They include high proportions of basal species, low proportions
of
top species, and much more complex webs with many links per species. These
differences are readily explained by the improved information, and by the
biology of lake ecosystems. The functional food webs show that strong species
interactions, including trophic cascades, are most prevalent at intermediate
productivities,

Abstract:
The remains of scales of Hysterocarpus traski Gibbons (Tule perch) were found
throughout a 27.44-m core from Clear Lake. Most scales occurred between the mud
surface and deposits approximately 11,000 years old. Changes in growth rates of
the animals were examined by measuring scale annuli and applying an empirically
established regression of fish length on scale radius. The data indicate a
pattern of accelerating growth rates, reaching a peak between reverse similar,
equals4000 and 2800 BP. After reverse similar, equals2800 BP, growth rates
decline markedly. Because the growth rates of these animals are essentially
dependent on temperature, the changes observed in the patterns of growth
probably reflect changes in climate in the northern Coast Range. The general
pattern of inferred temperature increase during the early and middle Holocene,
ending between reverse similar, equals4000 and 2800 BP, is consistent with
evidence from tree-line studies and palynology indicating higher temperatures
in parts of the western United States during this period.

Abstract:
Suspension-feeding fishes use gill structures for both respiration (lamellae)
and food capture (rakers). During hypoxic exposure in eutrophic lakes or poorly
circulated sloughs, many fishes, including Sacramento black-fish, Orthodon
microlepidotus, increase their gill water flows, in part by increasing
ventilatory stroke volumes. Stroke volume increases could compromise particle
sieving efficiency by spreading interdigitated gill rakers from adjacent gill
arches, although blackfish capture food particles by raker-guided water flows
to a sticky buccal roof. Using van Dam-type respirometers, blackfish
respiratory variables and feeding efficiency (Artemia nauplii) were measured
under normoxia (>130 torr PO2) and hypoxia (60 torr PO2). Compared with
non-feeding, normoxic conditions, gill ventilation volume, frequency, stroke
volume, and gape all increased, while O-2, uptake efficiency decreased, during
hypoxia and during feeding. O-2, consumption increased during feeding
treatments, and % uptake of nauplii showed no difference between normoxic and
hypoxic groups. Thus, blackfish display respiratory adaptations, including
increased ventilatory stroke volumes, to survive in hypoxic environments such
as Clear Lake, California. Importantly, they have also evolved a particle
capture mechanism that allows efficient suspension-feeding under both normoxic
and hypoxic conditions.

Title: Growth of juvenile sacramento blackfish, Orthodon microlepidotus
Abstract:
Growth rates of juvenile (1-8 g) Sacramento blackfish, an omnivorous California
cyprinid which grows to >1 .5 kg, were measured at three temperature ranges
in laboratory aquaria where several diets were offered ad lib . and at four
stocking densities in small ponds where natural food was available . Growth
rates generally increased with elevations in environmental temperature . Growth
in aquaria was possible with strictly plant-based diets, but was faster with
pelleted diets higher in protein, lipids, and total calories . Growth rates
in
ponds increased with decreased stocking densities and approximated or exceeded
those measured in laboratory aquaria for blackfish fed pelleted diets . The
data also support the importance of energy-rich food organisms (e.g.,
zooplankton) in the diet of young-of-the-year blackfish in Clear Lake,
California .

01504 Effects on organisms
Abstract:
The Clear Lake basin, like others in Northern California, is rich in
mercury-containing cinnabar ore. Mercury from the Lake sediment and water is
taken up by organisms and accumulates to levels detrimental to humans. For
example, fish muscle tissue concentrations exceed USFDA safe limits (1 ppm) in
bass Micropterus and catfish Ictalurus. It had been found that mercury is
present in freshwater fish species almost all as methyl mercury. While it is
well documented that mercury accumulates in animal tissues after exposure,
mechanisms underlying the uptake of mercury by fish are not fully understood.
There have been numerous direct toxicity studies as well as studies of
biochemical and physiological effects of mercury in fish. Many studies have
demonstrated experimentally that fish accumulate mercury directly from the
surrounding water as well as from food. In many studies, it has been
demonstrated that the accumulation of heavy metals in aquatic organisms can be
affected by the presence of suspended or dissolved substances, such as
sediment, humic substances and other sources of dissolved organic carbon (DOC).
About 50% of the DOC in uncolored surface waters of the U.S. consist of humic
substances. It has been well established that this aquatic humus, apparently in
solution, complexes with or chelates heavy metal ions in natural waters and thereby
changes the state of trace metals in solution. This reduces the amount of metal
that is "freely dissolved" and therefore the amount bioavailable to
fish. During the past 10 years, there have been several reports on the
influence of inorganic and organic chelators on the uptake, accumulation and
toxicity of heavy metals to living organisms.

Keywords:

Abstract:
The effect of dissolved organic carbon (DOC) on methylmercury (MeHg) uptake
across the gills of Sacramento blackfish (Orthodon microlepidotus) was
investigated using the Hg-203 radioisotope (half life 5 46.9 d). The efficiency
of fish gills in extracting MeHg (1.4 ng/L) from water was measured using a
McKim-type fish respirometer that separated exposure (inspired) water from
expired water. Blackfish gill ventilation and oxygen consumption rates remained
constant, while Me203Hg uptake was decreased significantly (p , 0.05) in the
presence of DOC (2 and 5 mg C/L). Mean Me203Hg extraction efficiency, uptake
rate constant, and blood to inspired water ratio decreased 78%, 73%, and 63%,
respectively, with 2 mg C/L of DOC, and 85%, 82%, and 70% with 5 mg C/L DOC,
compared to the Me203Hg reference treatment group. Because respiratory parameters
remained unchanged, reductions in Me203Hg uptake indicate strong interactions
between DOC and Me203Hg. Methyl203Hg levels in fish gills, kidney, and spleen
from 2 and 5 mg C/L were significantly lower (p , 0.05) than those observed
from the reference treatment group. These reductions in uptake
(bioavailability) support the hypothesis that trans-gill transport of Me203Hg
is inhibited when it is complexed by DOC in the aqueous medium, decreasing
Me203Hg uptake and accumulation in fish organs

Abstract:
The midge, or gnat, of primary concern in this study was the Clear Lake gnat,
Chaoborus astictopus Dyar and Shannon (Culicidae: Chaoborinae) , a species of
considerable economic concern to this area. Despite its great abundance in this
environment, this gnat species was found in less than 16% of the 1940 stomachs
examined from representatives of virtually every fish species occurring in
Clear Lake. Chironomid midges, on the other hand, though far less abundant than
chaoborids in this lake, were found in 43% of the stomachs examined. From an overall
evaluation of the results obtained, an attempt was made to explain possible
reasons why the Clear Lake gnat was not more heavily utilized for food. This
information will provide a basis to be used in evaluating those characteristics
most potentially desirable in any alien fish species under consideration for
introduction into Clear Lake as a possible biological control agent of the
Clear Lake gnat.

Abstract:
Menidia audens were introduced into Upper and Lower Blue Lakes, and in Clear
Lake, Lake County, during the fall of 1967, as a result of previous study
indicating a high potential for this species as a biological control agent for
aquatic midges, and as a forage species for game fishes. Although the species
has not as yet been recovered from Upper Blue Lake, it is doing well in Lower
Blue Lake, and has already become a predominant component of the fish
fauna of Clear Lake.

Abstract:
After repeated failures to control midges and algae at Clear Lake, California,
through conventional methods, a small fish, the Mississippi Silverside, was
introduced into the lake in 1967 as a possible means of biological control.
Algal levels in the lake have since declined and the Clear Lake
"Gnat" appears to be contained. Clear Lake may thus prove to be one
of the first examples of successful ecological pest management.

Abstract:
Clear Lake, Lake County, California, was treated to control the Clear Lake
gnat, Chaoborus astictopus Dyar and Shannon, during the summer of 1962 with 3
ppb methyl parathion. Concurrent with this control project, information was
gathered on representatives of the major trophic groups. This data was compared
with similar data gathered at the same time the previous non-treatment year to
determine if any immediate side effects of the insecticide were manifest.
Although it was impossible to study all the organisms involved with the
treatment, results indicated a possible depressing effect only upon the
zooplankton levels. No direct effects on the bottom fauna, other than C.
astictopus, or on the fishery were observed. || ABSTRACT AUTHORS: Authors

Abstract:
The population levels of the major insect groups subsequent to rotenone
treatment in the treated and untreated zones in robinson creek were examined in
both pools and riffles. a great resurgence of insect fauna after their initial
near annihilation in the treated zone was noticed. the simuliids were the first
major group to make a comeback in the treated riffles. within two weeks they
had taken over all available attachment space in the riffles. the authors feel
that elimination of potential predators may account for this resurgence. it
appears as if rotenone treatment had little lasting effect upon the non-target
insect fauna of significance as fish forage. the authors caution relating these
data to other instances of stream poisoning, since only a portion of robinson
creek was treated. season of treatment, sampling biases, and possible undetected
species shifts are other points to be considered in evaluation of such
projects. (sjolseth-washington)

Abstract:
When Nature was handing out her gifts so generously to California she was
guilty of one oversight: she left a serious scarcity of game fishes in the
warmer inland waters of the State. The salmon swarmed through San Francisco Bay
and the Delta to their spawning grounds in the cooler tributaries above, and
the steelhead swam up the coastal streams to lay their eggs and return to the
sea. But when the first white man came there was only one game fish which
resided permanently in the warm inland waters-the Sacramento perch, confined
mostly to the
Sacramento-San
Joaquin River system. The striped bass, the black basses, the sunfishes, the
catfishes, which are now so widespread and furnish so much fishing, are not
native sons; they have been brought by man from east of the Rockies since 1870.
The
purpose of this article is to tell something of the habits and the geographical
range of these fishes, and to enable anglers and others to identify them. It is
based to some extent on original observation and experience, but also draws on
the published work of others (see "References" at end). In its
preparation, valuable technical advice has been received from several members
of the Bureau of Fish Conservation of the California State Division of Fish and
Game, particularly from William A. Dill, Chester A. Woodhull, and Garth I.
Murphy; and valuable suggestions from Dr. R. W. Eschmeyer the Tennessee Valley

commercially in California. Rough fish landings in 1960 amounted to nearly a
half million pounds worth about $55,000 to the fisherman. Lakes and reservoirs
yielded 91% of all commercial landings with rivers and irrigation canals
supplying the remainder. Clear Lake, the main producer, contributed 57% of the
1960 catch. Three types of gear are used to harvest commercial rough fish;
shore seines accounted for the largest poundage followed by traps, and hook and
line. The best season for shore seining is during fall and winter when
reservoirs are shallow, water temperatures drop, and canals are drained. Carp
are more readily taken by trap from Aug. through Nov. No seasonal pattern is
evident for best hook and line fishing. || ABSTRACT AUTHORS: S. P. Davis

Abstract:
Clear Lake in northern California has received inputs of mercury (Hg) mining
wastes from the Sulfur Bank Mercury Mine (SBMM). About 1.2 million tons of
Hg-contaminated overburden and mine tailings were distributed over a 50-ha
surface area due to mining operations from 1865 to 1957 (Gerlach et al., 2001).
The SBMM includes an open, unlined mine pit, Herman Pit, which covers
approximately 23 acres and is 750 feet up gradient of Clear Lake. Reynolds et
al. (1997) analyzed water samples collected from Herman Pit and Clear Lake and
reported the pH values at those locations as 3 and 8, respectively. The SBMM
was placed on the Final National Priorities List (NPL) list in 1990. The site
has been under investigation as a Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA) site and has experienced some minor
corrective actions. Clear Lake remains under a fish advisory due to the mercury
contamination.

Abstract:
Unlike previous histories on the subject (the last being in 1976), this one is
fully documented by primary references to the original publication or other
sources. There are also explanations as to why some of the previous errors
occurred.
The
detailed history of each introduction, including the primary references, is
given. The subsequent history and status of each species in California is
given. The attitude of administrators, ichthyologists, fish culturists, fishery
biologists, fishermen, and the public toward each introduction is given, and
there is a discussion of their value. There is, with respect to California, a
review of the present regulations concerning introduced fishes, and a
prognostication of the future concerning them.
Approximately
111 full species of freshwater and euryhaline fishes occur in California.
(Salton Sea fishes are excluded.) of these, 53 have been introduced from
without the state and have been established successfully. Another five
subspecies or races have become established. Twelve introduced fishes have
uncertain status. Thirty-nine, including one marine fish which was deliberately
introduced, have achieved no lasting success. Eight introduced fishes are
listed as "hypothetical." Five were scheduled for introduction, but
the introductions were never completed. Three species have been listed
erroneously in scientific papers as having been introduced. About 26 other
species have been formally suggested as introductions. Three species are likely
candidates for introduction.

Abstract:
The Restoration Center is working to forge closer ties between NOAA and local
constituencies. In FY96, the Restoration Center began a community-based
restoration initiative to enable staff to become more directly involved in
local habitat restoration activities that benefit NOAA trust resources. To
date, this effort provided funds for 20 habitat restoration projects at the
local or community level, where the Center participation served as a catalyst
or essential element for project implementation. Through community-based
restorations, the Center hopes to form strong partnerships with local
government agencies and volunteer organizations, as well as promote stewardship
and a community conservation ethic for natural resources. The Adobe Creek Fish
Passage Project in California is an example of community-based partnership in
which a permanent step-pool fish ladder system was constructed to provide
passage for steelhead trout past a 12 foot blockage at the base of a culvert.
The project involved a partnership with the United Anglers of Casa Grande,
California Department of Fish and Game, and three Sonoma County Agencies. This
solution makes it possible for fish to ascend the perched culvert and continue
swimming upstream to spawn.

Abstract:
Mercury contamination of aquatic habitats results in bioaccumulation in fishes
to levels that threaten ecosystem function. For my dissertation research I
explore how factors such as foraging habitat and temporal variability in food
web structure can influence mercury concentrations in freshwater fish. In
Chapter 1 I analyze diets of six fish species from a mine-impacted lake and
show that mercury trophic transfer is positively related to the degree of
profundal foraging. Further, I show that energy from pelagic autotrophs drives
the benthic transfer of mercury to fishes, suggesting that pelagic detritus can
be strongly coupled with benthic mercury accumulation. Next, in Chapter 2 I use
20 years of monitoring data and archived fish samples to assess how a nonnative
fish invasion affected food web structure and mercury accumulation in Clear
Lake, California. I demonstrate that the invasion of a planktivorous fish
resulted in a dramatic decline in pelagic prey densities, causing an energetic
shift among fish to greater benthic reliance. Concomitant with this diet shift,
mercury concentrations increased in fish that previously foraged on pelagic
prey. Moreover, both diet and mercury concentrations returned to pre-invasion
benchmarks following the planktivore's collapse. Thus, transient perturbations
to a food web can shifts foraging habitats which can strongly determine mercury
levels in fishes. Lastly, in Chapter 3 I examine how mercury concentrations
vary in the food web of Eagle Lake, California and use an information theoretic
approach to determine important variables determining mercury concentrations in
fish. I show that fish length, date, pelagic reliance, and trophic position are
all important but the rankings of importance differ among species. Overall, my
dissertation highlights the need to incorporate the temporally dynamic
energy-flow paradigm of food webs, rather than a static topological approach to
understand mercury bioaccumulation in fishes. I show that foraging habitat can
be as important as trophic position and that mercury concentrations can respond
rapidly to transient food web perturbations. Thus, simplifying assumptions
regarding temporal stability, and the direction and magnitude of energy flow
can lead to spurious interpretation.

California: Effects of an Invasive Planktivorous Fish

Abstract:
The invasion, boom, collapse, and reestablishment of a population of the
planktivorous threadfin shad in Clear Lake, California, were documented over a
20 year period, as were the effects of changing shad populations on diet and
mercury (Hg) bioaccumulation in nearshore fishes. Threadfin shad competitively
displaced other planktivorous fish in the lake, such as inland silversides,
young-of-year (YOY) largemouth bass, and YOY bluegill by reducing zooplankton
abundance. As a result, all three species shifted from a diet that was
dominated by zooplankton to one that was almost entirely zoobenthos. Stable
carbon isotopes corroborated this pattern with each species becoming approximately
3% enriched in δ^13 C, which is elevated in benthic versus pelagic
organisms. Concomitant with these changes, Hg concentrations roughly doubled in
all three species. In contrast, obligate benthivores such as prickly sculpin
showed no relationship between diet or δ^13 C and the presence of
threadfin shad, suggesting that effects of the shad were not strongly linked to
the benthic fish community. There were also no changes in Hg concentrations of
prickly sculpin. The temporary extirpation of threadfin shad from the lake
resulted in zooplankton densities, foraging patterns, isotope ratios, and Hg
concentrations in pelagic fishes returning to pre-shad values. These results
indicate that even transient perturbations of the structure of freshwater
food-webs can result in significant alterations in the bioaccumulation of Hg
and that food webs in lakes cam be highly resilient.

foraging
Keywords:

Abstract:
Mercury (Hg) trophic transfer and bioaccumulation in fish from a mine-impacted,
eutrophic lake were examined in relation to foraging habitat, trophic position,
and size. Diet analysis indicated that there were clear ontogenetic shifts in
foraging habitats and trophic position. Pelagic diet decreased and benthic diet
increased with increasing fish length in bluegill, black crappie, inland
silverside, and largemouth bass, whereas there was no shift for prickly sculpin
or threadfin shad. Stable carbon isotope values (δ^13 C) were inversely
related to proportion of pelagic prey items in the diet, but there was no clear
relationship with benthic foraging. There were distinct differences between
pelagic and benthic prey basal δ^13 C values, with a range of ca. -28% in pelagic
zooplankton to ca. -20% in benthic caddisflies. Profundal prey such as
chironomid larvae had intermediate δ^13 C values of approximately -24%,
reflecting the influence of pelagic detrital subsidies and suppressing the
propagation of the benthic carbon isotope signal up the food chain. Fish total
mercury (THg) concentrations varied with habitat-specific foraging, trophic
position and size; however, the relationships differed among species and ages.
When corrected for species, length, and trophic position, THg and δ^13m C
were positively correlated, indicating that Hg trophic transfer is linked to
benthic foraging. When examined on a species specific basis, THg was positively
correlated with δ^13 C only for bluegill, largemouth bass, and threadfin
shad. However, diet-based multiple regression analyses suggested that THg also
increased with benthic foraging for inland silverside and black crappie. In
both species, benthic prey items were dominated by chironomid larvae,
explaining the discrepancy with δ^13 C. These results illustrate the
importance foraging habitat to Hg bioaccumulation, and indicate that pelagic
carbon can strongly subsidize the basal energy sources of benthic organisms.

Abstract:
In the last century, mining activities in many areas have increased the
likelihood of exposure to excessive amounts of mercury compounds through the
release of previously hidden, naturally occurring mercury (cinnabar). An
abandoned mercury mine site at Clear Lake. Lake County, CA has caused greatly
elevated amounts of mercury in the sediments near the mine site (Suchanek, et
al., 1993; Chamberlin, et al., 1990). Fish accumulate high concentrations of
mercury (Suchanek. et al., 1993). Fish-eating (piscivorous) birds are exposed
mainly via consumption of this contaminated food and the subsequent
bioconcentration of mercury by partitioning phenomena; piscivorous birds
therefore offer good bioindicators of mercury exposure. However, Clear Lake
also has many other factors that could affect survival, behavior, and
reproduction of birds.
This
study focuses on Clear Lake (high levels of mercury) and two other study sites
(Eagle Lake and Tule Lake with lower levels of mercury), each of whid'1
ext1ibits different combinations of environmental stressors. The wildlife of
Clear Lake may be exhibiting Icwer reproductive output than the other two lakes
because of the combination of stressors. Eagle Lake and Tule Lake, have a
different combination of environmental stressors. This paper examines the possibility
that mercury is causing or exacerbating reproductive problems of piscivorous
birds at Clear Lake.
Part
I of this report is a literature review on the dynamics and effects of mercury
in birds, as an introduction to understanding mercury as an environmental
contaminant. Possible effects of mercury will be addressed along with an
evaluation of levels that may cause those effects. Part II describes the field
study results, as well as pertinent conclusions.

Abstract:
Twenty-three healthy adult western and Clark's grebes (Aechmophorus
occidentalis and Aechmophorus clarkii) were collected at three study sites in
California, USA, in 1992: Clear Lake, Lake County; Eagle Lake, Lassen County;
and Tule Lake, Siskiyou County. Liver, kidney, breast muscle, and brain were
analyzed for total mercury (Hg) concentration (ppm wet weight), and blood was
analyzed for various blood parameters. Clear Lake birds (n = 13) had greater Hg
concentrations in kidney, breast muscle, and brain than birds from the other
two lakes (p < 0.05), whereas liver concentrations were not statistically
different (p > 0.05). Average concentrations for Clear Lake birds were 2.74
ppm for liver, 2.06 ppm for kidney, 1.06 ppm for breast muscle, and 0.28 ppm
for brain. The tissue levels of kidney, breast muscle, and brain at the other
two study sites were one half the levels found at Clear Lake. These mean tissue
levels were near, but below, those known to cause adverse effects. When data
from all sites were merged. kidney, breast muscle, and brain concentrations are
positively correlated to each other (p < 0.05). Liver concentrations were
not correlated to any other value. Brain Hg concentrations were also negatively
correlated to blood potassium and blood phosphorus levels (n = 11, p <
0.05). Kidney Hg levels were positively correlated to percent blood heterophils
and negatively correlated to percent eosinophils (n = 13, p < 0.05),
suggesting that mercury levels might be affecting immune function. These
biomarkers could not be related to any obvious ecological effects.

Abstract:
We report here the results of an experimental study designed to compare algal
responses to short-term manipulations of zooplankton in three California lakes
which encompass a broad range of productivity (ultra-oligotrophic Lake Tahoe,
mesotrophic Castle Lake, and strongly eutrophic Clear Lake). To assess the
potential strength of grazing in each lake, we evaluated algal responses to a
16-fold range of zooplankton biomass. To better compare algal responses among
lakes, we determined algal responses to grazing by a common grazer (Daphnia
sp.) over a range of Daphnia densities from 1 to 16 animals per liter. Effects
of both ambient grazers and Daphnia were strong in Castle Lake. However,
neither ambient zooplankton nor Daphnia had much impact on phytoplankton in
Clear Lake. In Lake Tahoe, no grazing impacts could be demonstrated for the
ambient zooplankton but Daphnia grazing had dramatic effects. These results
indicate weak coupling between phytoplankton and zooplankton in Clear Lake and
Lake Tahoe, two lakes which lie near opposite extremes of lake trophic status
for most lakes. These observations, along with work reported by other
researchers, suggest that linkages between zooplankton and phytoplankton may be
weak in lakes with either extremely low or high productivity. Biomanipulation
approaches to recover hypereutrophic lakes which aim only to alter zooplankton
size structure may be less effective if algal communities are dominated by
large, inedible phytoplankton taxa. (DBO)

Abstract:
Boron, chloride, sulfate, delta D, delta O-18, and H-3 concentrations in
surface water and groundwater samples from the Sulphur Bank Mercury Mine
(SBMM), California, USA were used to examine geochemical processes and provide
constraints on evaporation and groundwater flow. SBMM is an abandoned sulfur
and mercury mine with an underlying hydrothermal system, adjacent to Clear Lake,
California. Results for non-H-3 tracers (i.e., boron, chloride, sulfate, delta
D, and delta O-18) identify contributions from six water types at SBMM.
Processes including evaporation, mixing, hydrothermal water input and possible
isotopic exchange with hydrothermal gases are also discerned. Tritium data
indicate that hydrothermal waters and other deep groundwaters are likely
pre-bomb (before similar to 1952) in age while most other waters were recharged
after similar to 1990. A boron-based steady-state reservoir model of the Herman
Impoundment pit lake indicates that 71-79% of its input is from meteoric water
with the remainder from hydrothermal contributions. Results for groundwater
samples from six shallow wells over a 6-month period for delta D and delta O-18
suggests that water from Herman Impoundment is diluted another 3% to more than
40% by infiltrating meteoric water, as it leaves the site. Results for this
investigation show that environmental tracers are an effective tool to
understand the SBMM hydrogeologic regime.

Abstract:
The Clear Lake area of northern California is the location of hot spring
activity, some of which is associated with the formation of Au and Hg deposits.
129-I/I and 36-Cl/Cl ratios were measured in nine warm springs (formation
springs), six cold springs with elevated levels of Cl and I (mineral springs),
and five springs of recent meteoric origin. Dating of the I in the formation
waters indicated that sources of I in these waters are formations with minimum
ages between 60 and 80 Ma. This age range is in good agreement with the ages of
the Franciscan Complex and the Great Valley Sequence, the dominant formations
in this area. Because the mineral waters are essentially formation waters
diluted with meteoric water, I in these waters is of the same origin. Residence
times of the waters were calculated based on the build-up of 129-I and 36-Cl as
a consequence of the presence of U and Th in the crust. The residence time of the
formation waters in the Great Valley Sequence, the location for most of these
springs, was probably not longer than 84,000 yr. The concentrations found for
36-Cl and 129-I in the mineral waters indicate that these waters have residence
times of similar magnitude in formations such as the Franciscan Complex or the
Clear Lake Volcanics, which have slightly higher levels of U and Th than the
Great Valley Sequence. (Author's abstract)

ISSN:

Number: BIOSIS:PREV200600206976
Abstract:
Methylmercury has been thought to be produced predominantly by sulfate-reducing
bacteria in anoxic sediments. Here we show that in circumneutral pH sediments
(Clear Lake, CA) application of a specific inhibitor of sulfate-reducing
bacteria at appropriate concentrations typically inhibited less than one-half
of all anaerobic methylation of added divalent mercury. This suggests that one
or more additional groups of microbes are active methylators in these sediments
impacted by a nearby abandoned mercury mine. From Clear Lake sediments, we
isolated the iron-reducing bacterium Geobacter sp. strain CLFeRE, which can
methylate mercury at a rate comparable to Desulfobulbus propionicus strain
1pr3, a sulfate-reducing bacterium known to be an active methylator. This is
the first time that an iron-reducing bacterium has been shown to methylate
mercury at environmentally significant rates. We suggest that mercury
methylation by iron-reducing bacteria represents a previously unidentified and
potentially significant source of this environmental toxin in iron-rich
freshwater sediments.

Abstract:
Chapter 1 - The effect of Azolla filliculoides (Azfi) on the nutrient budgets
of Scirpus acutus, S. tuberosus. and Typha latifolia was investigated using
mesocosms and a mass balance approach. Nutrient levels remained low throughout
the experiment because no added nutrients were used and the macrophytes placed
heavy demands on the available nutrient pools. Azfi productivity and hence N
contribution to the system was severely limited under the oligotrophic
conditions. The three emergent macrophyte species: 1) produced significantly
different quantities of biomass based on their colonizing abilities and growth
characteristics, 2) had significantly different root:shoot ratios, and 3) had
significantly different tissue content of N and P. The mass balance analysis
along with the other analyses indicated that the significant differences
between macrophyte species in nutrient uptake, nutrient partitioning, resource
allocation and biomass were due to the growth characteristics of the
macrophytes. The addition of Azfi produced only limited changes in these
parameters.
Chapter
2 - Anion exchange membranes (AEMs) were used for measuring soluble reactive
phosphorus (SRP) in sediments of Clear Lake, CA. The results of AEM sampling
were correlated with the results of the dilute-acid Truog's P extraction and a
sequential P extraction (NH.CI, NaOH, HCI, and total). AEMs were also used to
measure the relative quantities of SRP at five paired lakeshore sites with and
without Scirpus acutus. A method for inserting AEMs in situ to measure deep
lakebed sediment SRP was developed. The only significant correlation was
between the NaOH extraction and the AEM results (r2=0.835, P<0.0001). The negative
correlation indicates that as the amount of iron- and aluminum-bound P
decreases, more SRP is adsorbed by the AEMs.
Chapter
3 - The Coordinated Resource Management and Planning (CRMP) process is being
used in Lake County by a group of government agency and citizen group
representatives to formulate long term, integrated and sustainable solutions to
a variety of environmental problems. The group makes recommendations for
implementing those solutions to the county Board of Supervisors. Examples of
changes in policy and regulations, and restoration projects that are
specifically related to the authors research are presented

Abstract:
The life history of the Clear Lake hitch (Lavinia exilicauda) is examined by
study of age, growth, size, fecundity, food habits, and spawning behavior. This
study is compared with a study of hitch
biology in Beardsley Reservoir and an earlier study of the Clear Lake
hitch done in 1947. Growth of Clear Lake hitch has remained about the same in
the Clear Lake studies. Both growth and maximum size of Clear Lake hitch are
greater than that of Beardsley hitch, as is fecundity. Clear Lake hitch spawn
in both the Lake and its tributaries; however, hitch recruitment. comes
entirely from stream spawning. Clear Lake hitch less than 50 mm are found
inshore, feeding on insects and zooplankton, while fish larger than 50 mm
become limnetic and exclusive zooplanktivores.

Abstract:
Growth, diet, and fecundity of Clear Lake hitch (Lavinia exilicauda chi) were
investigated to see if any changes had taken place following the establishment
of a large population of Mississippi silversides (Menidia audens) in the lake.
No changes were found. Hitch seem to avoid competing with silversides for
zooplankton by being limnetic in all except the early life history stages.
Fecundity was found to be higher than that of Beardsley Reservoir hitch, but
considerably lower than a previous estimate had indicated.

Abstract:
To assess the impact of elevated levels of inorganic mercury in soil and dust
and organic mercury in fish, biological monitoring was conducted among Native
Americans living next to an inactive mercury mine in Clear Lake, California. Of
resident tribal members, 46% (n = 56) participated in biomonitoring. Urine
mercury levels are equivalent to background, indicating that soil and dust
exposures among study participants are not substantial. The average blood
organic mercury level among study participants is 15.6 plus or minus 8.8 mu g/l
(n = 44), which is higher than levels reported by others among those who do not
consume fish (2 mu g/l). Consistent with results from other studies, a
correlation between fish consumption and blood organic mercury is observed (p =
0.03). The margin between observed and established adverse effect levels for
adults is examined for blood organic mercury and found to be less than 10-fold
for 20% of the study population. Protective public health efforts for the study
population and other similarly exposed populations, notably those who consume
commercial fish products, are considered.

Abstract:
The purpose of this study was to evaluate the trophic status of three natural
lakes in Lake County, California. From February through October 1972, monthly
samples of water (surface, mid-depth, and bottom) were collected from a
selected station on each lake and analyzed for temperature, dissolved oxygen,
carbon dioxide, orthophosphate, metaphosphate, nitrite nitrogen, nitrate
nitrogen, and phytoplankton and zooplankton. Plankters were classified to genus
or species and the numbers per cubic meter of water calculated. Partial
correlations were obtained between the number of plankters in each major
taxonomic grouping (i.e. Cyanophyta, Chlorophyta, Rotatorla, etc.. ) and each
water quality measurement. Significant positive correlations were found between
measurements of Cyanophyta density and dissolved oxygen, Chlorophyta density
and orthophosphates, Bacillariophyceae density and dissolved carbon dioxide,
Ciliata density and temperature, and Copepoda density and oxygen. Based on
water quality and plankton studies and basin morphology, Upper Blue Lake has
the least amount of enrichment, Lower Blue Lake has a slightly greater amount
of enrichment, and the Oaks Arm of Clear Lake has the greatest amount of
enrichment.
This
work was part of the M.S. Thesis presented by the author to the Graduate

Title: Emissions pathways, climate change, and impacts on California
Abstract:
The magnitude of future climate change depends substantially on the greenhouse
gas emission pathways we choose. Here we explore the implications of the
highest and lowest Intergovernmental Panel on Climate Change emissions pathways
for climate change and associated impacts in California. Based on climate
projections from two state-of-the-art climate models with low and medium
sensitivity (Parallel Climate Model and Hadley Centre Climate Model, version 3,
respectively), we find that annual temperature increases nearly double from the
lower B1 to the higher A1fi emissions scenario before 2100. Three of four
simulations also show greater increases in summer temperatures as compared with
winter. Extreme heat and the associated impacts on a range of
temperature-sensitive sectors are substantially greater under the higher
emissions scenario, with some interscenario differences apparent before
midcentury. By the end of the century under the B1 scenario, heatwaves and
extreme heat in Los Angeles quadruple in frequency while heat-related mortality
increases two to three times; alpine-subalpine forests are reduced by 50–75%;
and Sierra snowpack is reduced 30–70%. Under A1fi, heatwaves in Los Angeles are
six to eight times more frequent, with heat-related excess mortality increasing
five to seven times; alpine-subalpine forests are reduced by 75–90%; and
snowpack declines 73–90%, with cascading impacts on runoff and streamflow that,
combined with projected modest declines in winter precipitation, could
fundamentally disrupt California’s water rights system. Although interscenario
differences in climate impacts and costs of adaptation emerge mainly in the
second half of the century, they are strongly dependent on emissions from
preceding decades.

Abstract:
The Sulphur Bank Mercury Mine (SBMM) is an abandoned open pit mine located on
the eastern shore of Clear Lake, California where mining operations resulted in
deposits of waste material (overburden, tailings) stockpiled along the
shoreline. Because of Hg pollution of Clear Lake, SBMM is listed as an
Environmental Protection Agency (EPA) Superfund site. A survey was conducted at
SBMM to examine mercury (Hg) and arsenic (As) concentrations in plants and sods.
Compared to native soil, the waste materials had elevated concentrations of Hg
and As. Soils on the bare areas of the overburden material had much higher Hg
and As concentrations compared to vegetated areas. However, tissue
concentrations of Hg and As in oak and annual grasses were lower than levels
considered to cause toxicity in many species. A greenhouse study examined
interacting effects of lime, fertilizer and organic matter (OM) additions on
soil solution chemistry and As and Hg uptake by Zorro fescue (Vulpia myuros
L.). Fescue was grown on three mine-soils from SBMM containing high (164 mg/kg)
(S-H), medium (123 mg/kg) (S-M) and low (31 mg/kg) (S-L) As. Mercury in these
sods ranged between 1700-3000 mg/kg. Lime and OM additions were negatively correlated
with soluble Hg and Hg tissue concentration. Mercury uptake was more strongly
related to root length density (RLD) than to soluble Hg indicating that plant
root characteristics are an important factor affecting uptake. Compared to
total As, extractable As decreased in the order: total-As > oxalate-As >
dithionite-As > mixed acid-As > water soluble-As. Oxalate extractable Fe
correlated well with total As and As extracted by oxalate, dithionite and mixed
acid methods. Soluble As was strongly correlated with soluble P and DOC for the
sods. The effect of soluble P on soluble As was much greater in S-H than in S-M
or S-L; while the effect of DOC on soluble As was similar in S-H and S-M but
considerably lower than in S-L Since the solution phase was undersaturated with
respect to possible solid phase As containing solids, adsorption/desorption
reactions appear to control solution As in these soils.

01503 Characteristics, behavior and fate
Abstract:
One of the best-known examples of trophic concentration of pesticide residues
occurs in Clear Lake, California. The entire lacustrine ecosystem contains
chlorinated hydrocarbon residues, chiefly of the DDT series. The effects of
trophic concentration are most obvious in the Western grebe (Aechmophorus
occidentalis), a fish-eating bird, in which both acute mortality and
reproductive inhibition, presumably attributable to high residue loads, have
combined to cause population declines. This report centers on probable pathways
of residue transfer and on the precise manner in which reproduction might be
affected. Various aspects of the population biology of the Western grebe and
its prey species are described. The breeding population of this colonially
nesting species is approximately 150 pairs. Regular aerial censusing shows
variation in total numbers throughout the year as well as differential
distribution in the lake. Residue loads in grebe tissues have remained
relatively high over several years, averaging, as examples, in 1967 in DDD
alone 544 ppm (wet weight) in subcutaneous fat, 296 ppm (lipid weight) in eggs,
and 546 ppm (lipid weight) in the yolk sacs of hatchling grebes. All fishes
contain DDD and other residues. Residues in grebes vary seasonally and appear
strongly correlated with feeding rates and selection of prey types. Comparison
with another breeding population of grebes at Topaz Lake, California reveals a
different distribution and abundance of tissue residues and a different
seasonal variability. Maintenance of captive grebes has given precise
information on rates of growth and on feeding characteristics. Various
components of physiological, biological, and trophic concentration are
described in detail. Studies will continue for two additional reproductive
seasons.

Abstract:
The complex geological history of the Clear Lake region, which is given, has
influenced the evolution of fishes in the Clear Lake Basin. Of the 8 fams of
fish native to the area 3 include endemic spp. These are the Cyprinidae,
Embiotocidae and Cottidae. Details of subspp observed are given. All endemics
are derivatives of lowland spp common in the warm waters near the Delta, and
are the result of fluviolacustrine speciation. Intraspecific competition is
considered to be the most important selective pressure operative in the evolution
of lacustrine adaptations. The major adaptive difference between lake and river
populations in the region is in gillraker number. It is noted, however, that
minor differences in morphology and behaviour can reproductively and
ecologically isolate symapatric populations of lake-and river-adapted fishes.

Abstract:
Clear Lake in Lake County, California, has an endemic fish fauna composed of
five lake-adapted forms derived from lowland stream-adapted forms present in
surrounding drainage basins. Two of the five endemic forms are extinct. The
three remaining endemics maintain themselves despite the destruction of sloughs
and tule beds surrounding Clear Lake that are used for spawning and nursery
areas. Trophic specializations of the endemic fishes indicate past selection
for feeding on small benthic and pelagic invertebrates. The presence of fine
particles in the substrate and the reduced activity of tributary streams for at
least the past 10,000 years are major hydrographic features contributing to the
evolution of these trophic adaptations. Subfossil scales of the endemic Clear
Lake tuleperch (Hysterocarpus traskii lagunae), present in three U.S.
Geological Survey cores (CL-73-7 , -6, and -8), removed from the bottom of
Clear Lake in 1973 were analyzed by for age and growth rate. Periods of
increased scale growth were inferred to represent warming of the lake.
Comparison of the scale data with pollen data indicate that maximum scale
growth (core CL-75-8) occurred at about 19 ka, or 15 ka, during a cold
interval. Fluctuations in scale density in cores CL-73-4 and CL-73-7, however,
seem to follow fluctuations in oak pollen. It is therefore concluded that
maximum-scale growth represents cool periods, whereas maximum-scale density
represents warm periods in the history of the lake. During the period that
maximum-scale growth occurred, Clear Lake basin may have also been closed off
from surrounding basins and the lake enriched with nutrients. (See also

Abstract:
Day and night measurements of Nz fixation (as acetylene reduction) were made
during spring blooms of Aphanixomenonjlos-aquae and two autumn blooms of
Anabaena spp. From 9 to 23% of the 24-h fixation occurred between 1100 and 1300
hours. Nitrogen fixation in spring showed complex, physically shallow but
optically deep and mobile subsurface peaks of nitrogenase activity, which were
totally unrelated to Aphanixomenon biomass but may have been due to diel changes
in light penetrating the relatively clear water. Nocturnal fixation was
uniformly distributed with depth and accounted for t/J to $5 of daylight
fixation. In more turbid autumn waters, the pattern of N2 fixation for Anabaena
blooms was simpler, with a surface (or near-surface) peak decreasing with
depth. Nocturnal fixation was more uniformly distributed with depth. The
difference in fixation patterns between the two species is attributable to the
interactions of oxygen with the nitrogenase enzyme system. The diel changes in
nitrogenase activity suggest a need to establish whether the precursors of
nitrogenase accumulate in an oxygen-stable form.

Abstract:
Nitrogen fixation at three stages of an autumnal bloom of Anabaena circinalis
was measured after almost simultaneous collection at up to 32 stations in Clear
Lake and algal heterocysts, phytoplankton cell numbers, N03-N, NH4-N, dissolved
organic-N, P04-P, Fe, primary production, particulate carbon, and chlorophyll a
were also measured. Nitrogen fixation was significantly and positively
correlated to Anabaena heterocyst numbers (P >0.001), negatively correlated
to N03-N (P> 0.01), and positively correlated to dissolved organic-N (P >
0.01) and P04-P (P > 0.05). A negative correlation with NH4 is probable; no
significant relationship was found with the other variables measured. An
explanation of the apparent restriction of substantial cyanophycean N2 fixation
to nonoligotrophic waters is proposed. The results are consistent with the
theory that heterocysts are responsible for N2 fixation in situ under oxic
conditions.

Abstract:
The annual contribution of N2 fixation to Clear Lake in 1970 was about 550
tonnes, 500 Mg (megagrams) or 18 kg ha-\ 43% of the lake's yearly nitrogen
inflow. Biological N2 fixation can provide the nitrogen for almost half the
blue-green algal standing crop during blooms and is implicated as the main
cause of large algal nuisance blooms on this lake. The large quantity of
nitrogen fixed may be typical for large, shallow, cyanophyceandominated lakes.
A sustained spring peak of fixation was associated with a simultaneous bloom of
Aphanizomenon flos-aquae in all three basins, an autumn peak with an ephemeral
bloom of Anabaena circinaliY occurring at a different time in each basin. A
stepwise multiple regression analysis showed that fluctuations in N2 fixation
were best described by variations in heterocysts, quantities of blue-green
algae, P04-P, NOs-N, and temperature. Annual rates of N2 fixation were
correlated with the proportion of heterocysts to vegetative cells in
Aphanizomenon and with total number of heterocysts in Anabaena. Previous
nitrogen budgets for Clear Lake have shown a large excess of nitrogen in
outflow over inflow, which is accounted for by the levels of N2 fixation
measured.

it were estimated simultaneously for 31 sites at eight stages of the 1971 and
1972 spring blooms of Aphanixomenon in naturally eutrophic Clear Lake. The major
factor controlling rates of N2 fixation was the number of Aphanixomenon
heterocysts (P < 0.001). Environmental influences on fixation were largely
mediated through heterocyst induction or repression. Regression analysis showed
heterocysts highly negatively related to NO3 (P < 0.05). At high (linear
regressions) but not at low (log-transformed regressions) numbers, heterocysts
were positively correlated with phosphate (P < 0.05). At low rates of Nz
fixation, heterocysts were also positively related to water clarity,
chlorophyll (both P < 0.05), and temperature (P < 0.01). The role of very
low levels of nitrate (2-22 pg. liter-l NO,-N) in (apparently) indirectly
suppressing heterocyst induction was unexpected. Only at high rates was N,
fixation correlated with phosphate. Presumably at low rates sufficient
phosphorus is available in this P-rich lake (14- 43 pg*liter-’ PO,-P) to permit
repression of heterocyst formation by low NO, levels. Ammonium suppressed N,
fixation and heterocyst formation only where it was present in relatively large
quantities (20-170 pgmliter-’ NH,-N). Early in the blooms, low rates of
vegetative (i.e. nonheterocyst) N, fixation were indicated in the “flake
colonies of Aphanixomenon. These may have an anoxic center like that of Trichodesmium.

Abstract:
Although much is known about the biogeochemical cycling of mercury in the
environment, relatively little is known about methylmercury (MeHg)
bioaccumulation in fishes and how chronic sub-lethal exposures affect their
functioning. Several species of fish in Clear Lake, California have high MeHg
tissue levels, including Sacramento blackfish, Orthodon microlepidotus, a large
native cyprinid that is fished commercially. We fed juvenile blackfish one of
four diets containing MeHg (0.21 mg/kg control; 0.52 mg/kg low; 22.2 mg/kg
medium; and 55.5 mg/kg high treatments) for 70 days. There were no statistical
differences (P > 0.05) in food consumption among the treatment groups. By 35
days the high treatment group had a significantly depressed growth rate when
compared to the control group (P < 0.05) and by 70 days both the medium and
the high groups had significantly lower growth rates (P < 0.05). The
high-dose group had a significantly (P < 0.05) lower specific growth rate
(SGR) compared all other treatment groups at 35 days, although by 70 days these
differences were not significant. The wet/dry muscle mass and muscle mass/total
mass ratios, condition factor, and resting routine metabolic rates at both 35
and 70 days were statistically indistinguishable (P > 0.05) between
treatment groups. All treatment groups assimilated the dietary MeHg into muscle
tissue in a dose-dependent fashion. Percent assimilation was significantly
lower (P < 0.05) in the high-dose group compared to the low-dose group at 35
days, (control 53%, low-dose 61%, medium-dose 50%, and high-dose 40%) but at 70
days assimilation was lower (35, 43, 42, and 32%, respectively) and
statistically indistinguishable (P > 0.05) among the treatment groups.
Dietary MeHg concentrations and bioaccumulation rates were correlated (r(2) =
0.98 at 35 days, 0.99 at 70 days). These results may contribute to construction
of ecosystem mercury models and more informed natural resources management at Clear
Lake. (C) 2004 Elsevier B.V. All rights reserved.

Abstract:
It is proposed to construct a demonstration Hot Dry Rock (HDR) geothermal plant
in the vicinity of the City of Clearlake. An interim evaluation has been made
of the availability of surface water to supply the plant. The evaluation has
required consideration of the likely water consumption of such a plant. It has
also required consideration of population, land, and water uses in the drainage
basins adjacent to Clear Lake, where the HDR demonstration project is likely to
be located. Five sources were identified that appear to be able to supply water
of suitable quality in adequate quantity for initial filling of the reservoir,
and on a continuing basis, as makeup for water losses during operation. Those
sources are California Cities Water Company, a municipal supplier to the City
of Clearlake; Clear Lake, controlled by Yolo County Flood Control and Water Conservation
District; Borax Lake, controlled by a local developer; Southeast Regional
Wastewater Treatment Plant, controlled by Lake County; and wells, ponds, and
streams on private land. The evaluation involved the water uses, water rights,
stream flows, precipitation, evaporation, a water balance, and water quality.
In spite of California's prolonged drought, the interim conclusion is that
adequate water is available at a reasonable cost to supply the proposed HDR
demonstration project.

Abstract:
The general objective of this research was to understand the phylogenetic
relationships among two closely related freshwater minnows (Cyprinidae; Lavinia
symmetricus and L. exilicauda ) in California. In particular, the aims were to
(1) establish a phylogenetic hypothesis of relationships among currently
recognized subspecies of Lavinia ; (2) use molecular systematics and
morphological characters to define the evolutionary distinct Red Hills L.
symmetricus ; and (3) use a suite of molecular markers to document levels of
hybridization and introgression between L. symmetricus and L. exilicauda .
Phylogenetic relationships among Lavinia subspecies were estimated using two
mitochondrial genes and one nuclear intron. In the majority of cases,
recognized subspecies of Lavinia formed reciprocally monophyletic groups for
mitochondrial DNA (nDNA) and appeared fixed for subspecies-specific nuclear DNA
alleles (nDNA). In populations where L. symmetricus and L. exilicauda have been
known to hybridize (Monterey Bay Rivers and the Sacramento-San Joaquin Rivers),
mtDNA haplotypes and nuclear alleles were shared across species boundaries.
Molecular phylogenetics and multivariate analysis of morphological data for the
Red Hills subspecies of L. symmetricus were used to better understand the
historical relationships and the extent of gene flow between the
state-protected Red Hills populations and their widespread congeners. As in a
previous study, the Red Hills population was distinct morphologically from
neighboring populations. Molecular data further suggested that the Red Hills
populations are reciprocally monophyletic for mitochondrial DNA and thus form
an evolutionary unique assemblage. Hybridization between L. symmetricus and L.
exilicauda was estimated using three nuclear markers and one mitochondrial
marker. Lavinia symmetricus and L. exilicauda occur sympatrically in three
independent river drainages. The influence of drought conditions and low
rainfall were investigated to see if there was a correlation between these
environmental factors with either hybrid abundance or spawning between L.
symmetricus and L. exilicauda . Introgression of "alien" alleles were
similar for species, drainages, and nuclear markers. However, mitochondrial DNA
introgressed across species boundaries to a higher degree. Drought conditions
appear to play a role in that hybrids were more common when there was no
drought (as indicated by the Palmer Index). Spawning between L. symmetricus and
L. exilicauda appeared more common in years when there were drought or low
rainfall conditions.

Abstract:
Beginning with M. R. Harrington's controversial 1948 report on the Borax Lake
Site, the Clear Lake area of Lake County, northern California has been of
considerable interest as a candidate for early human occupation in western
North America. Both new and existing archaeological evidence have been examined
with the objective of elucidating the chronology and adaptations of early human
populations in the Clear Lake basin. Obsidian hydration dating and radiocarbon
dating constitute the primary analytical procedures. The research also
emphasizes studies of specific problems intrinsic to the successful application
of obsidian hydration and radiocarbon dating. The asemblages analysed consisted
primarily of local obsidian materials and included specimens from the Mostin
Site and several other contexts near Clear Lake. Obsidian hydration dating
reveals a general occupation of the study area at a time level equivalent to
the earliest use of the Borax Lake Site reported by Meighan and Haynes (1970).
Source characterization analysis indicates an overall predominance of Borax
Lake obsidian although Mt. Konocti and Napa sources were also utilized.
Obsidian hydration seriation of bifacial artifact specimens suggests potential
chronological significance for many of the types analysed, although most tool
categories exhibited considerable hydration range and overlap. Hydration data
from the Houx Site suggest that the Houx and Borax Lake components are of
nearly the same maximum age. Data also indicate some possibility for variation
in hydration rates due to microenvironmental conditions and intra-source
variation in obsidian composition. Analysis of contemporary lake shells
provides evidence of minor contamination of Clear Lake by magmatic carbon
emitted from gaseous springs. Most importantly, analysis of the Mostin Site
reveals an extensive burial population as well as considerable evidence for
habitation activities. Radiocarbon dating of Mostin Site human bone collagen
and charcoal results in ages between approximately 7000 and 11,000 radiocarbon
years B.P. The association of a conical stone pestle with a ca. 10,000 B.P.
dated Mostin Site burial implies substantially greater antiquity than is
normally attributed to this artifact form. Overall, the data provide extensive
evidence for widespread human occupation of the Clear Lake basin during
terminal Pleistocene and early Holocene times and confirm major importance for
this area in the study of early human populations in the New World.

Abstract:
Wetlands are valuable as sources, sinks and transformers of a multitude of
chemical and biological materials. Since the Industrial Revolution, wetlands in
many regions have been lost or changed their roles at an exponential rate
mostly due to human activities. These anthropogenic impacts should be evaluated
in the sense of wetland structure and function. Sediment cores were collected
from three montane marshes in the Northern Sierra Nevada, two mediterranean
inland marshes around Clear Lake, CA and six tropical inland marshes in Belize
to assess the impact of watershed environmental conditions altered by human
activities and climatic change. Pollen analysis was conducted in montane
marshes and physico-chemical characteristics were determined in all marshes.
Cores were <super>210</super>Pb dated with the Constant Rate of Supply
model or the Constant Initial Concentration model. Pollen analyses indicated
changes in plant communities caused by human activities. It was possible to
track the arrival time of introduced species from the combined pollen record
and <super>210</super>Pb date. Physico-chemical records documented
human activities such as logging, road construction and maintenance.
Establishment of unpaved roads in the marsh proximity was reflected in
increased sedimentation rate. Road salt application increased the concentration
of sodium and calcium. Water quality was responsible for the change of
sedimentation rate in the mediterranean marsh. Water level was responsible for
the change of plant community, resulting in the change of sediment
characteristics and sedimentation rate in tropical marshes. Relative values,
such as C/N, N/P, and P/Ca, as well as absolute concentrations of nutrients
were useful tools to assess the response of wetland sediments to the increased
nutrient input. Physical disturbance (road building) and vegetation change
caused by variation in water quality and water level were most important for
the change of sediment characteristics and sedimentation rate. This study
suggests that sedimentation processes should be evaluated in the context of
related physico-chemical and biological processes: change of water level,
change of nutrient input, response of plant and microbial communities
(production and decomposition). This work contributes to the fundamental
biogeochemical knowledge of the sedimentation process and provides information
potentially useful for wetland management and restoration.

Abstract:
The Clear Lake watershed, California, USA has been modified for agriculture
since the arrival of Europeans in the early 1800s, and this has led to the
deterioration of lake water quality. To assess the response of Clear Lake
wetland sediments to recent environmental changes caused by watershed
modification, physical and chemical properties of sediment cores at the inlet
(Rodman Slough) and outlet (Anderson Marsh) were analyzed. Pb-210 dating showed
increases of sedimentation rate for Anderson Marsh in the 1930s and 1980s, and
those increases corresponded to algal blooms and the increase of P input into
Clear Lake, respectively. Ranges of recent sedimentation and mass accumulation
rates in Anderson Marsh were 0.41-0.52 cm/yr and 1070-1380 g m(-2) yr(-1).
Accumulation rates-of P, Cal Mg, K, and Pb were slightly higher in Rodman
Slough than in Anderson Marsh. Sediment analyses showed that the excess P
originating from agricultural activities reach Clear Lake through Rodman Slough
and were removed in the lake.

From a total of 333 disk dangler and staple tags inserted between June, 1953,
and March, 1954, a 3-year return of 94 (28.2%) tags was received, 54 the 1st
year, 37 the 2d year, and 3 the 3d year. Movements were undirected. Survival
was calculated to be 44% and the annual expectation of death was 56%. Fishing
mortality accounted for 20% of the annual expectation of death and natural

Abstract:
Letter dated May 27, 1855, written by Eli Knapp to his wife, Mabel, no address.
One folded sheet of four closely-written pages, it begins with "Clear Lake
Nappa Co Cal"and the salutation "Dear Mabel" and ends abruptly
with Knapp's signature. Transcription included. Eli describes his journey to
Clear Lake: "I Left Grass valley for the purpose of viewing on May the 8th
went on foot to Mariesville at which place I bought a Mule Saddle & Bridle
& rope Called here Lassso or Lariat for stakeing out animals in this
country and some provisions necessary." In the "Seaport town on the
sacramento river (Collousa)", Knapp takes up with Mr. Stewart, Mr. Rawlens
and Mr. Handy and they jointly venture to Clear Lake where they intend to stake
out claims and settle down to farm and ranch. Settlement at Clear Lake is just
beginning: "... first settlers came in last summer." Knapp comments
on the fine prospects there as if to justify his extended stay away from home.
His plan is to ranch, perhaps begin a dairy. "I feel queer to step out of
my Cabin Because I cant walk without treading on Claover and Oats eaqual in
quantity to any I have eaver Cultivated my range in preferable to any I have seen
... " He talks also of the abundance of game and fish, including mention
of the Indians fishing with scoop nets. He is most anxious to have family join
him "At a proper time after Indian difficulties are settles I want my
family here I want you fathers family here Mother knapp Elliott & horace
and all good neighbors ... " He sends a message to his children "tell
children I have got a spoted watch puppy that will stay all day to the cabin
and watch and will sleep out with my little mule if i want him to whose back is
about as high as Ellies Head and who will let children ride him as well as any
boddy." He ends with "if we succeed i hoap for better Digings on Deck
than I have long since been accustomed to I will try and write often Mr H will
remail yours by order I trust I have you co-operation. ... I have written bad
on bad paper which i have carried some 150 [miles?]"

Bio/History:
There is little biographical information about Eli Knapp beyond what can be deduced
from this letter. He evidently came to California somewhat prior to 1855,
possibly from a town called Windsor, state unknown, and had spent some time in
Grass Valley. He left a family including his wife, Mabel, and two sons, Elliott
and Horace. There is also a reference to extended family members, "Mother
Knapp", "Pa", "Brother Alexander and Lady(?)",
"Paul Grant", etc. Nor can we determine anything about his fate after
1855. There are several E. Knapps and variants in later census (1860 and 1870)
-- but no definite identification is possible.
Unrestricted.

Abstract:
Hardhead (Mylopharodon conocephalus) and Sacramento squawfish (Ptychocheilus
grandis) are large cyprinids native to the Sacramento-San Joaquin river system
in California. Although squawfish are widely distributed, hardhead are more
restricted and found only where squawfish are present. The microhabitats and
temperature requirements of both species were studied to determine reasons for
this phenomenon. Microhabitat data from 17 stream sites were compiled,
including measurements on fish size, total water depth, fish focal point depth,
focal point velocity, and substrate composition. The data were divided (120 mm
SL) into two fish size categories. Total water depths were greater for adults
over juveniles of both species. Substrates were primarily of the gravel-boulder
range, with few differences between species or size classes. Principal
components analyses were similar for both species--water velocity variables
were important primarily and depth variables were important secondarily. Both
species were found in slow water (<15 cm/s) of moderate depths (mostly
0.5-2.0 m) with most fish near the bottom or less than halfway up in the water
column. Squawfish were observed in shallower water and closer to the substrate
than hardhead. Temperature requirements of both species were determined by
laboratory studies of acute temperature preferences, routine metabolic rates,
and critical thermal maxima. Acute final temperature preferenda for hardhead
and squawfish were 28.4 and 26.0(DEGREES)C, respectively, determined by linear
regressions of preferred against five acclimation temperatures. Squawfish had
higher and more variable metabolic rates at every acclimation temperature above
10(DEGREES)C. Partial results for hitch (Lavinia exilicauda), California roach
(L. symmetricus), Sacramento blackfish (Orthodon microlepidotus), Sacramento
perch (Archoplites interruptus), tule perch (Hysterocarpus traski) and
Sacramento sucker (Catostomus occidentalis) are also presented. Critical
thermal maxima were very consistent (e.g. low variability), ranging from
28.3(DEGREES)C for squawfish at 10(DEGREES)C to 38.1(DEGREES)C for hitch at
30(DEGREES)C. The laboratory results generally agree with field observations of
activities and macrohabitats. Successful management of these native fishes
depends on maintaining adequate summer stream temperatures (25-30(DEGREES)C).
Although the hardhead-Sacramento squawfish association phenomenon could not
directly be explained, this study is the first to quantitatively describe the
microhabitat and temperature requirements of hardhead.

Abstract:
Bass feed heavily on Hitch, as shown in stomach contents of lake record
Largemouth bass. Anglers use lures that imitate hitch, 5 inches long, technique
known as "hitching or ripping". Bass are opportunistic predators and
the bass population is cyclical. DFG has been conducting electroshocking for 20
years on lake. Silverside introduced by vector control. Plankton drift on the
lake, hitch and silversides follow. Threadfin shad, cyclical fish as well with
current low numbers. He feels that the #
of birds represents # of bait fish present. Pelicans can consume 4 lbs. of fish
a day, currently low numbers of pelicans and cormorants. Ospreys, grebes, etc.
Told to look up commercial fishing harvest for blackfish and carp, knows of a
father and son team.Very minimal tribal fishing recently.

Abstract:
The Sulphur Bank Mercury Mine on the eastern shore of Clear Lake is the source
of poor quality acid mine drainage seeping into Clear Lake. Lateral and
vertical geochemical trends in ground water composition point to a number of
redox reactions taking place as a function of subsurface water-rock
interactions. An understanding of these reactions suggests opportunities to
remediate the acid mine drainage through suppression of undesirable geochemical
reactions. Two geochemically based remediation steps are proposed.

Abstract:
The growth of black crappie (Pomoxis nigromaculatus) and of white crappie (P.
annularis) before a new forage fish, the Mississippi silverside (Menidia
audens), became established in Clear Lake, California, was compared to their
growth after the silverside had become established. Following the establishment
of the silverside, growth rates of both species were slower than the
presilverside growth rates for the first two years of life, and were apparently
faster beyond year II. No correlation was found between changes in
climatological conditions and crappie growth patterns. The overall impact of
the silverside on the crappie fishery in Clear Lake may be negative if
increased juvenile mortality rates result from the smaller sizes observed at the
younger age classes.

Abstract:
17 spp. of fish taken in Clear Lake are listed. The digestive tracts from 355
fish comprising 10 spp. were examined. All stages of Chaoborus were found in 9
spp. of fish, but it is believed that all spp. feed on this insect at some time
during their life. The fork-tail catfish, square-tail catfish and split-tail
are important feeders on all stages of the gnat. As many as 1,076 larvae have
been found in the stomach of a 9-inch fish; several thousands have been
estimated in the intestine. Nearly 77% of the stomachs of the square-tail catfish
that contained food material had Chaoborus larvae; 100% of the intestines
showed larval remains. Indications of abundance of various species of fish were
sought from gill net catches, spawning runs, commercial seining, and illegal
fishing. Clear Lake apparently harbors an enormous fish population. Data on the
water chemistry are given. ABSTRACT AUTHORS: A. W. Lindquist

Abstract:
Thirteen collections taken from clear lake, california, between 1959 and 1965,
comprising eight fish species, four bird species and one plankton sample, were
analyzed for tde (ddd) residues. colorimetric method (before 1962) and electron
capture gas chromatography were used to determine concentrations of pesticide.
no well-defined year-to-year trend in residue levels was noted when all samples
were examined together. white catfish showed some tendency toward increased
residue levels with increasing age, while mean annual tde residue in largemouth
bass (1958 year class) decreased from 23.5 parts/million (ppm) in 1958 to 7 ppm
in 1963. evidence indicates that tde contamination, originating from three
applications for insect control in 1949, 1954 and 1957, is declining. mean
annual levels in white catfish have declined from 85.7 ppm (1958) to 9.6 ppm
(1965) and levels in largemouth bass have declined from 40.9 ppm (1958) to 12.2
ppm (l963). tabular data include results of flesh and fat analyses for all
collections and a comparison of data derived by colorimetric and gas
chromatographic methods. (voigtlander-wisconsin)

Abstract:
Mortalities of western grebes(Aechmophorus occidentalis) occurred at Lake
Berryessa, Napa County, California in 1982 and 1986. Kidney and liver tissues
of those birds and others from Lake Berryessa and Clear Lake were analyzed to
determine if mercury, known to occur in these locations, was present at
deleterious levels. Residue analyses indicated mercury was present at hazardous
levels (20 ppm, wet weight) in the two instances.

Abstract:
Spatial and temporal variations in sediment microbial community structure in a
eutrophic lake polluted with inorganic mercury were identified using polar
lipid fatty acid (PLFA) analysis, Microbial community structure was strongly
related to mercury methylation potential , sediment organic carbon content, and
lake location. Pore a ater sulfate, total mercury concentrations, and organic
matter C/N ratios showed no relation ships with microbial community structure.
Seasonal changes and changes potentially attributable to temperature regulation
of bacterial membranes were detectable but were less important influences on
sediment PLFA composition than were differences due to lake sampling location.
Analysis of biomarker PLFAs characteristic of Desulfobacter and Desulfovibrio
groups of sulfate-reducing bacteria suggests that Desulfobacter-like organisms
are important mercury methylators in the sediments, especially in the Lower Arm
of Clear Lake.

Abstract:
In 1971, flood control levees extending 1,540 miles were maintained under
cooperative state and federal agreements in the sacramento and san joaquin
valleys and in lake and placer counties. such flood control projects include
the sacramento, american, san joaquin, calaveras, and truckee rivers;
littlejohns and middle creeks; merced county stream group; sacramento river
bank protection project, and the lower san joaquin flood control project; and
the fresno county stream group. twice during 1971, department of water
resources specialists inspected and classified the quality of levee maintenance
performed by maintaining agencies. this bulletin reports both the 1971 ratings
and the method of rating, discusses proper maintenance procedures, and reports levee
construction by the u.s. army corps of engineers, channel maintenance,
applications for levee encroachments, and the condition of the flood control
project structures. maps locate project levees and local maintenance agencies.

Abstract:
Clear Lake is the largest and oldest lake completely within the California
border. It supports a complex warmwater fishery and is a popular lake for both
novice and professional anglers. The objective of this study was to update the
description of the spring sport fishery of Clear Lake by documenting catch
composition by size and species, angler success, angler origin, and tournament
activity. Boat anglers were interviewed from March 2 through June 26, 1988. Of
the 31 fish species which inhabit Clear Lake, 11 were noted during this survey.
Largemouth bass dominated the catch (67%), followed by bluegill (15%), and
crappie (6%). Catfishes, Sacramento hitch, carp and Sacramento perch together
comprised 12% of the total sport catch. Catch per unit effort for largemouth
bass taken in Clear Lake is 0.21 fish/h. Catch per unit effort is 0.25 fish/h
when largemouth bass is the target species.

Abstract:
During mid-Aug. of 1948, 1956, 1957, and 1958, fingerling largemouth bass
(Micropterus salmoides) were collected and their stomach contents analyzed.
Mean fork lengths ranged from 2.1 inches in 1956 to 3.6 inches in 1958.
Plankton and insects were the most important foods for bass under 2.5 inches
fork length, while fish became the major food for larger bass. In 1948,
Sacramento blackfish (Orthodon microlepidotus) were the major food item with
bluegills (Lepomis macrochirus) of only minor importance. In all later
collections, blue-gills constituted over half of the fish consumed, and were
the most important single item. Blackfish, with one exception, were not found
in any of the stomachs examined during the later studies. ABSTRACT AUTHORS:

Abstract:
In August and September of 1952, 722 white catfish and 724 brown bullheads were
single-tagged with disk-dangler, staple, or hydrostatic tags. Anglers
voluntarily returned 15.2% of the white catfish tags and 6.5% of the brown
bullhead tags. Additional tagging was done in 1954-55. It was found that huge
underfished stocks of these fish exist in Clear Lake. Hydrostatic tags proved
unsuitable for long-term mortality studies. || ABSTRACT AUTHORS: C. M. Ferrel

Abstract:
Examination of 510 stomachs of Sacramento perch from five localities showed
that they feed primarily by picking insect larvae and snails from the bottom
and aquatic plants or by capturing zooplankton, fish, or emerging insects in
midwater. The diet varies with season and size of fish but no daily feeding
rhythms were found. Similarity of their diet to that of bluegill indicates that
Sacramento perch may have been eliminated from their native habitat through
competitive interactions with bluegill.

Abstract:
Young-of-year largemouth bass in Clear Lake, California, switched from feeding
largely on bluegill (Lepomis
macrochirus)
to feeding largely on Mississippi silverside or on a mixture of prey species
following the establishment of
the
silverside in the lake in 1967. Choice of prey, however, was influenced by
relative abundance of the prey, the
habitat
occupied by the bass, time of day, and size of the bass. The bass usually
switched to a predominantly fish diet at
a
smaller size when silversides were the main prey than when bluegill or
Sacramento blackfish (Orthodon microlepidotus) were the main prey. The success
of the introduction of small numbers of Florida largemouth bass into the lake
in 1969-1971 was demonstrated by the presence of significant numbers of bass
that could be classified as intergrades between Florida and northern largemouth
bass (M.s. salmoides), the subspecies originally introduced into Clear Lake. No
meaningful differences in the feeding habits or average lengths of the
intergrades and "pure" northern bass were found.

Introduction
Hybridization
between species of Cyprinidae is'a comm~n occurrence in North America, but
large numbers of any hybrid combination are rarely found (Schwartz 1972). Few
hybrids have been found among the 10 species of native cyprinids found in the
Sacramento-San joaquin drainage of central California. Alii known cases of
hybridization involve the hitch, Lavinia exilicauda, which has been reported to
hybridize with thicktail chub, Gila crassicauda (Miller 1963); California
roach, Lavinia symmetricus 1 (Avise, Smith, and Ayala 1975); and
Sacramento
blackfish, Orthodon microlepidotus (Hopkirk 1973). While hitch- roach hybrids
may be locally abundant, the other hybrids are known only from a few
individuals. The hitch-blackfish hybrid combination has been previously
represented by a single juvenile individual from Coyote Creek, Alameda County
(Hopkirk 1973). This note reports the presence of adult hitch-blackfish hybrids
in the catches of commercial blackfish fishermen from San Luis Reservoir,
Merced County. The hybrids are common and distinct enough that they wer
noticed
by the fishermen and consequently called to our attention.

Abstract:
Collections were made of fishes occurring in the streams of the Sierra Nevada foothills
in Central California. Environmental factors associated with each collection
were recorded. Correlation analyses indicated which environmental factors
affected the distribution of 11 of the 21 spp collected: Micropterus salmoides,
Lepomis cyanellus, L. macrochirus, Gambusia affinis, Notemigonus crysoleucas,
Lavinia exilicauda, Ptychocheilus grandis, Mylopharodon conocephalus,
Hesperoleucus symmetricus, Catostomus occidentalis and Salmo gairdneri. The
fishes were found to belong to 4 distinct fish associations, each found in a
distinctive set of environmental conditions. The Rainbow Trout Association was
found in the cold, clear permanent streams of the higher elevations. The
California Beach Association was found in the small, warm Intermittent tributaries
to the larger streams. The Native Cyprinid-Catostomid Association was found in
the larger low elevation streams. The Introduced Fishes Association was found
in low elevation intermittent streams that had been highly modified by man's
activities.

Abstract:
Sacramento splittail were once widely distributed throughout the Central
Valley, to which the species is endemic. Splittail have disappeared from much
of their native range because of the loss or alteration of lowland habitats
following dam construction, water diversion, and agricultural development. They
are now largely confined to the Sacramento-San Joaquin estuary. Population
levels appear to have fluctuated strongly over the past two decades, with a
general decline since 1986, the last year of strong recruitment. Recruitment of
young to the population evidently is episodic and depends upon sufficient flows
in the lower reaches of rivers during spawning and subsequent high outflows
through the Delta. Principal spawning areas and juvenile rearing habitat need
to be identified and protected. Water management to maintain adequate water
flows throughout the Delta at appropriate times will be necessary to promote
successful population recruitment and, hence, preservation of the species.

Abstract:
The Sacramento perch, a primitive centrarchid, is restricted to the
Sacramento-San Joaquin and allied drainages. At the present time its numbers
are greatly reduced. A brief study of the life history of this fish was made in
1947 The principal departure from the life histories of other members of the
family Centrarchidae lies in the spawning behavior. Spawning Sacramento perch
aggregate into schools and deposit their eggs on plants, bare rock, and algae
covered rock without prior nest-building activity. Subsequent guarding of the
eggs is probably non-existent, or at best, weakly developed, with the exception
of territoriality of the males during spawning. It is possible that the failure
of this fish to guard its exposed eggs is responsible for its marked reduction
subsequent to the introduction of several possible "egg eating" spp.
into California waters. || ABSTRACT AUTHORS: G. I. Murphy

Abstract:
The Sacramento hitch (Lavinia exilicauda) is restricted to the Sacramento-San
Joaquin drainage. A brief study of its life history was made in 1947 Hitch
deposit non-adhesive eggs over gravel riffles of slight gradient in the streams
tributary to Clear Lake during Mar. and Apr/ The eggs lodge in crevices and
hatch in about 10 days at 62 F. At a length of 2.5 cm. the young migrate
downstream to the lake. They range the littoral zone until Aug. when they move
into off-shore waters. Their principal food is plankton. Males first spawn at
the end of their 1st yr. at a length of 10 cm.; females first spawn at the end
of their 3d year of life at a length of 25 cm. Variations in rainfall as
reflected in the condition of the spawning streams cause marked fluctuations in
the success of hitch spawning. Under certain conditions hitch may be a valuable
forage fish for warm water game fish. || ABSTRACT AUTHORS: G. I. Murphy

Abstract:
This cyprinid is native to the Sacramento-San Joaquin and Pajaro River drainage
systems. Specimens from 1.6 to 3.0 in. in length appear to feed selectively on
animal plankton, small midges, algae, etc., the selection varying from
individual to individual. Fish over 3 in. long feed on plant and animal
plankton, bottom detritus, and diatoms. Foods are extracted by brushlike
branching gill rakers. Spawning takes place in April, May, and June. The eggs
are adhesive and are placed on plant material at a depth of about 3 ft. A
17-in. female contained approx. 350,000 maturing eggs. The majority first spawn
at the end of their 3d year and most fish die after their 2d spawning. Young
blackfish occupy the littoral zone during their 1st summer. After their 1st
year they leave the shore and do not return until they spawn. At 1 yr.,
blackfish are 4.3 in. long; at 2, males are 10 in. long, females 10.2; at 3,
males are 13.6 in. long, females 14.3; at 4, males are 15.4 in. long, females
16.3; at 5, females are 17.2 in. long. The blackfish may prove useful as a
forage fish in other waters, particularly fluctuating reservoirs. || ABSTRACT

Abstract:
The introduction of exotic fish, land cultivation, and intensified irrigation
have changed considerably the fish population of Clear Lake. The
stream-spawning cyprinids, which serve as forage fish, are greatly depleted,
leading to increased predation on young game fish. There is now a poor
production of fish per acre, although the growth of game fish is good. To
increase the supply of forage fish, commercial fishing for the greaser
blackfish was stopped and a lake-spawning shiner (Notemigonus crysoleucus)
introduced. Angling has had no noticeable effect on the fish population except
to reduce the number of old fish. || ABSTRACT AUTHORS: G. F. Weisel

Abstract:
The critical swimming velocity (Ucrit) of four California stream fishes,
hardhead, Mylopharodon conocephalus, hitch, Lavinia exilicauda, Sacramento
pikeminnow, Ptychocheilus grandis, and Sacramento sucker, Catostomus
occidentalis was measured at 10, 15, and 20
C.
Hardhead, Sacramento sucker, and Sacramento pikeminnow swimming performances
tended to be lowest at 10
C,
higher at 15
C,
and then decreased or remained constant at 20
C.
Hitch swimming performance was lower at 10
C
than at 20
C.
There were no significant differences among species at 10 or 15
C,
although pikeminnow and hitch were ca. 20% slower than hardhead or sucker. At
20
C
hardhead, Sacramento sucker, and Sacramento pikeminnow had remarkably similar
Ucrit but hitch were significantly (by 11%) faster.We recommend that water
diversion approach velocities should not exceed 0.3 ms−1 for hitch (20–30
cm total length) and 0.4 ms−1 for hardhead, Sacramento pikeminnow, and
Sacramento sucker (20–30 cm TL).

Abstract:
"The Yaqui farmers are forced to work as exploited laborers on their own
land. They are provided virtually no information about the chemicals they
apply," [Margaret Reeves] told Indian Country Today. Attracting about 300
people, the workshop was hosted by the North-South Indigenous Network Against
Pesticides, a project of the International Indian Treaty Council. It was held
in coordination with the Traditional Yaqui Authorities of Potam, Torim, Vicam,
Rahum and Huirivis Pueblos and the local Yaqui organization, "Yaquis
United for Mother Earth." "Three children were at the conference as
testimony to the cruel and avoidable injustice wielded on the Yaqui people by
those who own and control the local systems of agricultural production, by the
chemical companies and by the negligent Mexican regulatory authorities,"
she said.

Abstract:
Since the advent of environmental land use planning laws in the 1970's, local,
state, and federal agencies have been requiring the identification and
protection of archaeological resources. This cultural resource management (CRM)
activity has generated many volumes of reports listing properties inspected,
prehistoric site locations, and other information needed to serve land use
planning needs. This dissertation attempts to understand the type of data
contained in these studies and develops a suite of analytical techniques which
can utilize this information to generate meaningful inferences about prehistoric
cultural and natural processes. The data used in the current study comes from
the Clear Lake Basin, located in California's North Coast Range. The least cost
model of subsistence economics is applied to ethnographic, paleo-environmental,
and archaeological data in an effort to develop a hypothetical scenario
outlining the periods and expected economic changes which occurred in the
region. Archaeological expectations concerning settlement pattern, technology,
and population for each period are developed. The CRM data from the Clear Lake
Basin is studied using the concepts of constrained exploratory data analysis,
remnant settlement patterns, and persistent place. A combination of obsidian
hydration and diagnostic artifacts is used to place sites within a
chronological framework. Patterns derived from the exploratory data analysis
are then compared with the expectations which were derived based on previously
existing data and the least cost model. Through the use of site distribution
maps, changes in site area and site size over time, the current analysis
succeeds in identifying the earliest evidence of settlement in the Clear Lake
Basin, outlines periods of major economic change, and suggests various
motivating factors which may have led to this change. The following aspects of
Clear Lake Basin and surrounding regional prehistory are entertained: (1)
Regional resource areas which were in use during various periods throughout
prehistory; (2) Major technological/economic changes, when they occurred, and
the circumstances which may have led to their inception, and; (3) The
demographic history of the Clear Lake Basin (Pomo) inhabitants and how it
effected the prehistory of surrounding regions.

Abstract:
Since its development in the early 1980s, the mass-balance approach
incorporated in the Ecopath software has been widely used for constructing
food-web models of marine and other ecosystems. Generalizations on the
structure and functioning of such ecosystems, relevant to the issue of
fisheries impacts, have been developed and these have affected the evolution of
the Ecopath approach. Thus, the description of the average state of an
ecosystem, using Ecopath proper, now serves to parametrize systems of coupled
difference and differential equations, which are used to depict changes in
biomasses and trophic interactions in time (Ecosim) and space (Ecospace). The
outcomes of these simulations can then be used to modify the initial
parametrization, and the simulations are rerun until external validation is
achieved. This reconceptualization of the Ecopath approach as an iterative
process, which helps address issues of structural uncertainty, does not
increase its input requirements markedly. Rather, it has become possible,
through a Bayesian resampling routine, to explicitly consider the numerical
uncertainty associated with these inputs. We present the key features of the
reconceptualized approach, and two indices based thereon for quantifying the
ecosystem impacts of fisheries. We conclude with a brief discussion of its
limitations, both present and intrinsic.

Abstract:
M. salmoides floridanus had a notable genetic impact following their
introduction into five northern California waters containing northern
largemouth bass, M. s. salmoides , populations: Folsom Lake, New Hogan
Reservoir, Lake Amador, Lake Isabella, and Clear Lake. Information from this
study and from a similar study at southern California waters indicates that
introductions of Florida bass into northern bass populations have generally
been beneficial through reducing high exploitation rates, increasing the mean
size of bass in the catch, and providing exceptional fishing for trophy-sized
bass at some waters. Results of this study indicate that current largemouth
bass populations possess a wider spectrum of performance capabilities through
the inclusion of desirable traits attributed to Florida bass. This is
particularly advantageous in the reservoir setting where heavy angling
pressure, water level manipulation, competition of prey species with small
bass, and other factors work against the maintenance of a bass population.

Title: Fishery Survey at Clear Lake, Lake County, California
Abstract:
16 species captured during 1972 survey including: Largemouth bass, bluegill,
green sunfish, crappie, catfishes, blackfish, goldfish, hitch, carp,
silversides, sculpins, tule perch, and one splittail. Commercial fishing for
blackfish and carp has been to sustain numbers and large sizes of these
species. Largemouth bass population is quite low. Young-of-year probably
compete for same food items.

Abstract:
Fishing has long been a principal attraction at Clear Lake(Murphy, 1951;
Hinton, 1971). Today Clear Lake supports one of the most important warmwater
fisheries in California. Historically, the sport fishery was comprised of
rainbow trout and Sacramento perch. Changes in the watershed however, have
created a habitat suitable only for warmwater species, such as bass, catfish,
and crappies.
Clear
Lake is being considered as a route for exporting water, developed in the Eel
River Basin, to southern conveyance systems. This could result in a diversion
through the lake of over 1 million acre-feet per year. In order to evaluate the
impact of this proposed routing on the Clear Lake sports fishery, it was
necessary to gather information on current angler use and sport fish yield.
These data will be used to demonstrate the value of the Clear Lake sports
fishery and to provide a base for comparing changes in the fishery which may
result from the diversion of water through the lake.
The
objectives of this study were (1) to estimate the existing level and seasonal
trends of use, and to determine the quality, pattern, and yield of the sport
fishery; and (2) to provide basic data needed for developing management plans
for the lake.

Abstract:
The process of zooplankton grazing and its impact upon algal populations as a
possible management technique to alleviate eutrophication problems is examined.
grazing rates are expressed as clearing volumes--volume of water filtered
(cleaned) of algae or other particles of a defined type per unit time--and are
measured for common representatives of important freshwater zooplankton.
zooplankton often exhibit considerable selectivity in their grazing and there
are usually pronounced difference in feeding efficiency depending upon the size
of the algae. many blue-green algae are not grazed at all, perhaps contributing
to the obnoxious blooms. phytoplankton biomass seems to cause an increase in
zooplankton, which then graze the phytoplankton intensely, reducing
phytoplankton biomass, although other hypotheses could be operative. it appears
from the estimations presented that grazing is more likely to be a dominant
term in the biomass equation in eutrophic than oligotrophic lakes. zooplankton
grazers may derive a significant proportion of their nutrition from sources
other than algae, perhaps detritus and bacteria. several schemes are
conceivable in considering zooplankton as populations whose manipulation might
contribute to control of algal blooms. although management of zooplankton for
control of eutrophication symptoms is not impossible, no proven techniques
exist at present. (see also w73-12391) (jones-wisconsin)

Abstract:
PCBs, like some other contaminants, both bioaccumulate and biomagnify. They
settle in fatty tissue in their animal and human hosts. It is suspected that
PCBs can be passed from human mothers to babies in the womb through the
placenta. It is known that PCBs pass from mothers to nursing babies through
breast milk, which is a rich fluid high in fat. This is not a reason not to
breastfeed your child. If you suspect you have had significant levels of PCB
exposure, you should talk to your doctor about breastfeeding. Women of
childbearing age and pregnant and nursing mothers are urged to be extremely
cautious about eating fish from tainted areas. Some cautionary notices advise
that women stop eating fish for up to a year prior to an anticipated pregnancy.
Young children and babies have much lower tolerance for toxins than do adults
and are at higher risk. According to the OEHHA, suspected effects of PCB
contamination in humans include cancer, gastrointestinal discomfort, anemia,
fatigue, and acne-like skin irritations. In children, lighter birth weights and
delayed development of mental function and muscle coordination are suspected.
In animals, PCBs affect the liver, stomach, thyroid glands, and reproduction.
The other big culprit is mercury, which appears in California waters as
methylmercury. This means that it has gone through a methylization process and
is now part of a larger hydrocarbon molecule. There are also inorganic forms of
mercury (elemental mercury). The OEHHA states "mercury is released from
the earth as a vapor, condenses in clouds, and then falls in rain. Rain water
runs off the land, also carrying with it mercury from soil and rocks, and
particularly from tailings from abandoned mercury mines." In California,
especially in the Coastal Range, mercury was mined in the form of cinnabar ore.
This was converted to liquid metallic mercury that was then used to extract
small amounts of gold from ore in the Sierras. Now there is contamination at many
of these mining sites in both the Coastal Range and the Sierras. Industrial
sources such as paper making, burning of fossil fuels, and large-scale earth
disturbances such as mining and dam building can also increase the amount of
mercury in our environment. Different advisories have been issued for different
parts of California. In Clear Lake and Lake Berryesa, due to elevated mercury
levels, nine fish species are on the advisory list. These include largemouth
and small-mouth bass, white and channel catfish, rainbow trout, brown bullhead,
Sacramento blackfish, crappie, and hitch. Carp is not listed here for Clear
Lake but some people do eat them. Carp appear as a "less safe" fish
on a cautionary notice for the Lake Erie Basin. An advisory exists for the San
Francisco Bay and Delta Region because of mercury, PCBs and other chemicals,
with sturgeon and striped bass as named species. In the Salton Sea (Imperial
and Riverside Counties), croaker, orangemouth, corvina, sargo, and tilapia are
listed. Los Angeles and Long Beach harbor have recommended limits for white
croaker, queenfish, surfperches, and black croaker. The overall list is
daunting and more than a little discouraging, yet not having this information
can be dangerous. If you or your tribe are not sure about the water in your
area, seek testing. If you feel like a "lone wolf" in your concern
about water contaminants, there are private companies that analyze water
samples for a fee. Before you take this step, contact a state office such as the
OEHHA to see if testing is in progress or planned for your area.

Abstract:
The internal dynamics of Clear Lake, California-a large, multibasin and
polymictic lake-are examined using simulations conducted with a
three-dimensional (3D) hydrodynamic model. The model is based on an accurate
and efficient semi-implicit finite difference algorithm for the hydrodynamic
equations, that has been previously subject to extensive verification with
analytical test cases. The high level of agreement-without extensive
calibration-between the model results and the observations at several locations
in the lake is comparable with previously published 3D modeling results. The
model results confirm the baroclinic-pumping model of circulation proposed for
the Oaks Arm of Clear Lake in Part I. The simulations show that the interaction
of stratification, periodic wind forcing, and Coriolis effects drive this
circulation. The diurnal readjustment of the circulation from being wind driven
to baroclinically driven is examined and shown to vary spatially. This
transition in circulation-type has a wavelike nature, with a distinct frontal
structure and converging currents at the surface. Asymmetries in the forcing
and response, combined with rotational effects, impart a cyclonic residual
circulation on the flow.

Abstract:
The fauna of California has undergone marked changes In the last 125 years, and
this is especially true of the fishes of the Sacramento-San Joaquin Valley. Many
of the native fish species have become severely depleted, and a few have been
brought to the verge of extinction. Little quantitative information is avail-
able from which to judge either the early abundance of these depleted forms or
the rapidity of their decline. Since archaeology can provide one source of such
information, fish remains from a historic Indian midden in the Sacramento
Valley were investigated.

need abstract
The
new approach to ecosystem health is proactive. As a result, the scope of
environmental studies is growing and the methods are evolving. Integrated
Assessment of Ecosystem Health aggressively broadens the range of ecotoxicology
to include its related fields. The book begins with John Cairns, Jr.'s
predictions and recommendations for the future ecotoxicology: "New goals
must lead to new techniques.... the field of ecotoxicology is in the early
stages of a major paradigm shift that is driven by three interrelated forces:
1) heightened interest in sustainable use of the planet, 2) protection of
ecosystem , and 3) the shift from emphasis on avoiding deleterious effects to
maintaining them in robust health." Later chapters explore the integration
of data, intrinsic remediation studies and the ever- increasing number of
associated disciplines that are improving our environmental potential.
Methodology, itself, is considered as an evolving tool, always in need
examination and revision. Cairns, and his co-authors all advocate a constructive,
offensive new form of ecoscience. The consensus of scientists is clear: toxic
threat and, especially, habitat destruction are the most important environmentl
issues, today. The mandate from Integrated Assessment of Ecosystem Health is
also decisive: expand the parameters of ecoscience. The future of life on earth
depends upon our ability to grow and learn.

Abstract:
In addition to affecting biogeochemical transformations, the speciation of As
also influences its transport from tailings at inoperative mines. The
speciation of As in tailings from the Sulfur Bank Mercury Mine site in Clear
Lake, California (USA) (a hot-spring Hg deposit) and particles mobilized from
these tailings have. been examined during laboratory-column experiments.
Solutions containing two common, plant-derived organic acids (oxalic and citric
acid) were pumped at 13 pore volumes d(-1) through 25 by 500 mm columns of
calcined Hg ore, analogous to the pedogenesis of tailings. Chemical analysis of
column effluent indicated that all of the As mobilized was particulate (1.5 mg,
or 6% of the total As in the column through 255 pore volumes of leaching).
Arsenic speciation was evaluated using X-ray absorption spectroscopy (XAS),
indicating the dominance of arsenate [As(V)] sorbed to poorly crystalline
Fe(III)-(hydr)oxides and coprecipitated with jarosite [KFe3(SO4,
ASO(4))(2)(OH)(6)] with no detectable primary or secondary minerals in the
tailings and mobilized particles. Sequential chemical extractions (SCE) of
<45 mu m mine tailings fractions also suggest that As occurs adsorbed to Fe
(hydr)oxides (35%) and coprecipitated within poorly crystalline phases (45%).
In addition, SCEs suggest that As is associated with 1 N acid-soluble phases
such as carbonate minerals (20%) and within crystalline Fe-(hydr)oxides (10%).
The finding that As is transported from these mine tailings dominantly as As(V)
adsorbed to Fe (hydr)oxides or coprecipitated within hydroxysulfates such as
jarosite suggests that As release from soils and sediments contaminated with tailings
will be controlled by either organic acid-promoted dissolution or reductive
dissolution of host phases. (C) 2007 Elsevier Ltd. All rights reserved.

Abstract:
The ability to predict sprouting of aquatic macrophyte vegetative propagules is
an important step in understanding their temporal distribution and abundance
and in developing long-range management strategies. We examined the ability of
degree-day based equations to predict monoecious hydrilla, (Hydrilla
verticillata L. f. Royle) tuber and turion sprouting in Clear Lake, California
using sediment and water temperatures measured in the lake. Sediment
temperature data were used to calculate accumulated degree-days. Sprouting of
turions and tubers was estimated using previously developed equations relating
sprouting to accumulated degree-days. There was good agreement between
sprouting predictions and field data on the presence of hydrilla in weed rake
samples. Small differences among water temperatures at the five sites and
strong relationships between water and sediment temperatures indicate that
sprouting should be similar in hydrilla beds found along the western and
southern shores of upper Clear Lake. These results can be used to estimate
optimal timing for surveys of hydrilla abundance and the application of
hydrilla management techniques.

Abstract:
Clear Lake, California receives acid mine drainage and mercury (Hg) from the
Sulphur Bank Mercury Mine, a USEPA Superfund site active intermittently from
1873-1957, and partially remediated in 1992. Hg concentrations were analyzed
primarily in four species of Clear Lake
5
fishes: inland silversides (Menidia beryllina, planktivore), common carp
(Cyprinus carpio, benthic scavenger/omnivore), channel catfish (Ictalurus
punctatus – benthic omnivorous predator), and largemouth bass (Micropterus
salmoides – piscivorous top predator). These data represent one of the largest
fish Hg datasets for a single site, especially in California.
Spatially,
total Hg (TotHg) in silversides and bass declined with distance from the mine,
indicating that the mine site represents a point source for Hg loading to Clear
Lake. Temporally, fish Hg has not declined significantly over 12 yrs since mine
site remediation. Hg concentrations were variable throughout the study period
with no monotonic trends of increase or decrease, except those correlated with
boom and bust cycles of an introduced fish, threadfin shad (Dorosoma
petenense). However, stochastic events such as storms also influence juvenile
largemouth bass Hg as evidenced during an acid mine drainage overflow event in
1995.
Compared
to other sites regionally and nationally, most fish in Clear Lake exhibit Hg
concentrations similar to other Hg-contaminated sites, up to ca. 2.0 mg/kg wet
weight (ww) TotHg in largemouth bass. However, even these elevated
concentrations are less than would be anticipated from such high inorganic Hg
loading to the lake. Hg in some Clear Lake largemouth bass exceeded all human
health fish consumption guidelines established over the past 25 years by the
USFDA (1.0 mg/kg ww), the NAS (0.5 mg/kg ww) and the USEPA (0.3 mg/kg ww). Hg
in higher trophic level fishes exceed ecotoxicological risk assessment
estimates for concentrations that would be safe for wildlife, specifically the
non-listed common merganser and the recently delisted bald eagle.
Fish
populations of 11 out of 18 species surveyed exhibited a significant 1 decrease
in abundance with increasing proximity to the mine; this decrease is correlated
with increasing water and sediment Hg. These trends may be related to Hg or
other lake-wide gradients such as distribution of submerged aquatic vegetation.

Abstract:
The Sulphur Bank Mercury Mine (SBMM), active intermittently from 1873-1957 and
now a USEPA Superfund site, was previously estimated to have contributed as
least 100 metric tons (10^5 kg) of mercury (Hg) into the Clear Lake aquatic
ecosystem. To better quantify the contribution of the mine in relation to other
sources of Hg loading into Clear Lake and provide data that might help reduce
that loading, we analyzed Inputs and Outputs of Hg to Clear Lake and Storage of
Hg in lakebed sediments using mass balance approach. We evaluated Inputs from
(1) wet and dry atmospheric deposition from both global/regional and local
sources, (2) watershed tributaries, (3) groundwater inflows, (4) lakebed
springs and (5) the mine. Outputs were quantified from (1) efflux
(volatilization) of Hg from the lake surface to the atmosphere, (2) municipal
and agricultural water diversions, (3) losses from out-flowing drainage of
Cache Creek that feeds into the California Central Valley and (4) biotic Hg
removal by humans and wildlife. Storage estimates include (1) sediment burial
from historic and prehistoric periods (over the past 150-3,000 years) from
sediment cores ca.2.5m depth dated using dichloro diphenyl dichloroethane
(DDD), ^210^Pb and ^14^C and (2) recent Hg deposition in surficial sediments.
Surficial sediments collected in October 2003 (11 years after mine site
remediation) indicate no reduction (but a possible increase) in sediment Hg concentrations
over that time and suggest that remediation has not significantly reduced
overall Hg loading to the lake. Currently, the mine is believed to contribute
ca.322-331 kg of Hg annually to Clear Lake, which represents ca. 86-99% of the
total Hg loading to the lake. We estimate that natural sedimentation would
cover the existing contaminated sediments within ca. 150-300 years.

Abstract:
Mining operations conducted at the Sulphur Bank Mercury Mine at Clear Lake,
California, from 1872-1957, together with acid mine drainage since abandonment,
deposited ca. 100 metric tons of mercury (Hg) in the sediments of Clear Lake.
In 1992 Hg in surficial sediments (up to 183 mg kg(-1) total Hg and 15.9 mu g
kg(-1) methyl Hg) exhibited a classic point source distribution with maximum
concentrations adjacent to the mine. However, the ratio of methyl:total Hg in
sediments increased with distance from the mine, suggesting either differential
transport of methyl Hg or a non-linear relationship between sediment inorganic
Hg concentrations and methylation. Water exhibited an even more gradual decline
in total Hg concentrations with distance from the mine, in both unfiltered
bottom water (max, ca. 70 ng L-1) and filtered surface water (max. ca. 7 ng
L-1). In comparison with other studies, Clear Lake exhibits high total Hg in
sediment and water, yet relatively low methyl Hg concentrations. Our findings
indicate a non-linearity between total and methyl Hg concentrations in sediments.
The ratio of methyl:inorganic Hg is approximately 2 orders of magnitude higher
in the water column than in the sediments, making the methyl fraction much more
available for downgradient transport away from the mine. Particulate Hg
comprises ca. 33-94% of the total Hg and ca. 25-78% of the methyl Hg in the
water column. Geothermal springs do not appear to represent a significant
source of Hg to Clear Lake. The present pattern of Hg distribution in Clear
Lake shows that water column transport plays some role in the lake-wide
contamination of methyl Hg, but high methylation at relatively low inorganic Hg
concentrations cannot be ruled out. No quantitative estimate of the area of
sediments requiring remediation is possible from these descriptive data alone.

Abstract:
Mercury (Hg) in the aquatic ecosystem of Clear Lake has been documented since
the 1970s when fishes were found to have elevated levels of toxic methyl
mercury (meHg). Mining practices at the Sulphur Bank Mercury Mine (active
intermittently from 1872-1957) along the shoreline of Clear Lake included the
bulldozing of waste rock and overburden ore into the shallow nearshore regions
of the lake and the creation of steeply sloped piles of waste rock at the
water's edge. This process, plus erosion of the waste rock piles, resulted in
the accumulation of an estimated 100 metric tons of Mg in Clear Lake. A
monitoring program to assess Mg in Clear Lake was established in 1992, and
conducted continuously from 1994. Drought conditions in California had
persisted for fa. 6 yrs prior to 1992, when the U.S. Environmental Protection
Agency (USEPA) remediated the steeply sloped eroding waste rock piles, which
appeared to reduce sediment Hg concentrations significantly. In April 1995, a
white flocculent material was observed in Clear Lake adjacent to the mine and
has been observed every year since, leading to the discovery of ongoing acid
mine drainage (AMD), low pH fluids high in Mg and extremely high in sulfate.
AMD is now believed to be the most likely cause of elevated meHg in Clear Lake.
The discovery of this source of meHg production in Clear Lake, which will significantly
influence remedial options, was only made possible by implementation of a
diligent monitoring program.

Abstract:
Benthic invertebrates from Clear Lake, site of an inactive mercury (Hg) mine,
were analyzed for population and community level parameters in response to a
significant point source of sediment-associated Hg. Using multiple regression,
at least one taxon (Placobdella leeches) showed a significant decline and
another taxon (Procladius midges) showed a significant increase in response to
increasing sediment Hg. Responses of invertebrates to sediment Hg levels are
complex, likely due to partial confounding between sediment Hg (especially
methyl Hg), grain size and depth. Stepwise multiple regression analyses
indicate that individual taxa often responded significantly to several
environmental factors. Chironomus populations declined with increasing grain
size, depth and total Hg; Procladius declined with increasing depth, but
increased with increasing sediment grain size and Hg levels; Chaoborus declined
with increasing depth; oligochaetes increased with increasing TOC; and
Placobdella leeches declined with both increasing depth and sediment Hg levels.
Additional multi-variate routines were used to demonstrate more complex relationships
than are typically elucidated by standard multiple regression statistics. The
complex results presented here may indicate that there are significant
population effects above some threshold of sediment Hg concentrations.
Community level parameters (diversity and evenness) declined with increasing
sediment Hg levels, but with considerable variation at low Hg levels. Simple
regression yielded a negative relationship between diversity and evenness
versus sediment total Hg that was nearly significant, and one with sediment
methyl Hg that was not close to significance. Multiple regression indicated
that depth was more important than sediment Hg in describing the variation in
diversity.

Title: Mercury, a Gold Rush legacy, haunting coastal creeks
Abstract:
THIS IS THE ARTICLE
SACRAMENTO
(AP) - Mercury from California's Gold Rush days is lingering in three waterways
flowing from the coastal mountains northeast of San Francisco, prompting
warnings Tuesday from state health officials.
The
California Environmental Protection Agency's Office of Environmental Health
Hazard Assessment issued a draft advisory warning against consuming too much
fish from Clear Lake, Cache Creek and Bear Creek in Lake, Yolo and Colusa
counties, respectively.
The
draft advisory recommends that no one eat any fish or shellfish from Bear
Creek, a 39-mile-long tributary of Cache Creek.
For
Clear Lake and Cache Creek, the draft advisory recommends women of childbearing
age and children age 17 and younger eat bass, catfish and certain other fish no
more than once a month, and men and women beyond childbearing age no more than
once a week.
If
none of those fish are eaten, women of childbearing age and children 17 years
and younger can have one meal a week of bluegill, hitch, carp, trout or
crayfish, while women beyond childbearing age and adult men can have up to
three meals a week of those fish.
An
advisory has been in place since 1987 for Clear Lake, but the new proposal
includes the entire 81-mile length of Cache Creek from Clear Lake to the Yolo
Bypass of the Sacramento River, as well as the North Fork of Cache Creek and
all of Bear Creek.
Mercury
can affect the nervous system. Naturally occurring mercury can accumulate in
fish and shellfish at many times the concentrations of the surrounding
environment. Mercury was mined in the Clear Lake area starting in the
mid-1800s.
State
scientists plan to discuss the draft advisory Friday at the Lake County
Coordinating Resource Management Committee meeting in Clearlake. The public has
until June 16 to comment.

Abstract:
Mercury measurements in lake sediments from cores from Clear Lake, California,
reveal that high Hg levels (up to 65 ppm) have been characteristic for the
sediments for >10,000 yr. A strong Hg anomaly occurs in sediments deposited
between 10.5 and 8.5 (thousand yr), which the authors relate to a period of
relatively rapid tectonic subsidence of part of Clear Lake. It is hypothesized
that mercury-rich geothermal fluids rose along the activated fractures and
faults and were discharged into the lake, causing the anomalously high Hg
content of the sediments and leading to deposition of the Sulphur Bank Hg
deposit. The total amount of Hg discharged into Clear Lake over the past 15 ka
is estimated to be at least 2400 metric tons. Chemostratigraphy of lake
sediments in geothermally active areas may hold promise for the detection and
dating of major paleoseismic periods. (Author 's abstract)

Abstract:
Dichotomous keys were developed from examination of preserved and live
specimens to identify the early life stages for 11 species of cyprinid fish
(minnows) residing in Suisun Bay (the Bay) and the extended area associated
with the Sacramento-San Joaquin River Delta (Delta). Three keys were developed
for each of the 11 species based on 3 defined life stages: prolarvae-postlarvae,
late postlarvae-prejuvenile, and early juvenile. Keys are presented for
goldfish, Carassius auratus; red shiner, Cyprinella lutrensis; common carp,
Cyprinus carpio; California roach, Hesperoleucus symmetricus; hitch, Lavinia
exilicauda; hardhead, Mylopharodon conocephalus; golden shiner, Notemigonus
crysoleucas; Sacramento blackfish, Orthodon microlepidotus; fathead minnow,
Pimephales promelas; splittail, Pogonichthys macrolepidotus; and Sacramento
pikeminnow, Ptychocheilus grandis. A description of spawning habits,
developmental biology, and life histories for each species are also included.
This report places special emphasis on the early life stages and spawning of
splittail. Catch and salvage of adult splittail in spawning condition, observed
behavior of newly hatched larvae, and the widespread collection of prolarvae
suggest that the Bay and Delta are both used for spawning. Based on data
presented in this report, we conclude that splittail are not all potamodromous:
some reside and spawn each year in the suitable habitat of the Bay and Delta.

Title: Modern Fishes of Clear Lake, California
Abstract:
The composition of fish species in Clear Lake has changed dramatically over the
last century in response to habitat alteration and the introduction of
non-native species. Urban and agricultural encroachment has destroyed nearly
84% of the original vast marsh complex. A total of 15 non-native species have
become established in addition to 12 native species. The synergistic effect of
habitat manipulation and fish introduction has resulted in the extirpation of
two native species (one indigenous to Clear Lake), and the near extirpation of
the only centrarchid native to Clear Lake.
Existing
fish populations are generally found near remnant marshes reflecting the direct
life support function of these areas. Distribution patterns of prehistoric fish
fauna were probably similar.

Title: Chi Council for the Clear Lake Hitch Interim Report on Activities
Abstract:
THIS IS THE ARTICLE
Introduction
In
early spring, hitch migrate up streams tributary to Clear Lake to spawn.
Longtime residents vividly recall the vast numbers of spawning hitch in every
tributary to Clear Lake. Over the past 50 years, the numbers of spawning hitch
have plummeted dramatically. In recent years, no hitch have been sighted in
some major tributaries during the spawning season.
Early
in 2004, the Lake County Group of the Sierra Club organized volunteers to
survey the hitch migration. In August of 2004, the Chi Council for the Clear
Lake Hitch was formed with the assistance of the Eastlake & Westlake
Conservation Districts as a Coordinated Resource Management and Planning (CRMP)
organization. The organizers were Sierra Club members, local landowners,
tribes, state and local governmental agencies and interested citizens.
As
stated in its Memorandum of Understanding, the goals of the Chi Council are to:
Study,
protect, restore, and maintain the watershed ecosystem leading to a restored
population of Clear lake Hitch
Study
and recognize the "lake effect" on the hitch population by the
introduction of nonnative fish, the condition of the shoreline habitat, the
effects of pollutants in the water column, and aquatic conditions generally
Study
the fish population during migratory runs
Streams
have been monitored in each of the successive spawning seasons. The data has
been compiled by Chi Council and posted on its website at
www.lakelive.org/chicouncil.
Summary
of Findings
Spring
hitch surveys made over the past four years have resulted in the following
observations:
The
numbers of hitch that spawn in the creeks each year appear to be declining.
In
the major tributaries of Middle Creek and Clover Creek, hitch were observed in
2004 & 2005; none were observed in 2006 or 2007.
No
hitch have been observed over the past four years in Seigler or Schindler
Creeks.
Conversely,
significant numbers of hitch have been observed in Adobe Creek each year.
For
over 30 years, physical barriers in Kelsey, Scotts, Middle and Clover Creeks
have deprived hitch of access to miles of historic spawning beds.
The
causes for the decline in the hitch population are not clearly identified or
understood
The
effect of non-native species of fish in Clear Lake on hitch populations is not
yet understood.
The
Need for Scientific Research
Two
of the objectives of the Chi Council are to:
Establish
scientific protocols for the monitoring of the hitch population, and
Encourage
scientific research on hitch and their habitat through colleges, universities
and other agencies.
While
volunteer surveys of hitch spawning have provided significant information regarding
current hitch populations and the location of physical barriers to streambed
access, scientifically designed and supervised studies are needed to answer
fundamental questions regarding the condition and fate of this important native
fish. The Chi Council has solicited assistance from the University of
California to help organize and conduct such studies.
Removal
of Physical Barriers
Modification
or removal of physical barriers in the creeks to allow free passage of spawning
hitch is a vital first step to restore a viable population of hitch. The Chi
Council urges ongoing, focused efforts by governmental agencies and private
parties to achieve that end.
Volunteer
Support Is Vital
Monitoring
of the spring hitch migration is essential to learn more about hitch behavior
and establish population trends. The continued participation of volunteers to
monitor the hitch spawn is vital to the success of this project. For detailed
results of past surveys, log onto the Chi Council's website at www.lakelive.org/chicouncil.
Thank
you for your continued support of the Chi Council to save the Clear Lake hitch
from extinction.

Abstract:
Birds and mammals exposed to waterborne mercury (Hg) and methylmercury (MeHg)
were collected and/or sampled at Clear Lake, California, USA, to field test the
predictive wildlife criteria model developed for the Great Lakes Water Quality
Initiative (GLWQI). Tissue samples collected from sampled animals were analyzed
for Hg and organochlorine residues, and for selected physiologic parameters
known to be affected by Hg. All mammalian organ tissues analyzed contained less
than 12 ppm total Hg, wet weight. All avian tissue samples analyzed contained
less than 3 ppm total Hg, wet weight. No evidence of Hg-associated health
effects was found. Tissue Hg residues were compared with water, sediment, and animal
food samples to characterize bioaccumulation of mercury in the Clear Lake food
web. Total Hg bioaccumulation factors for the Clear Lake site closest to the Hg
source were: TL-2: 11,100; TL-3: 31,200; TL-4, 190,000. Our results support the
final wildlife criterion (1,300 pg/L) and suggest that the GLWQI model, with
site-specific modifications, is predictive for other Hg-bearing aquatic
systems.

Abstract:
Simple and reliable diagnostics are needed for the assessment of sublethal
effects of toxicants. An ideal diagnostic would respond to a variety of
toxicants and stressors and could be applied across different types of systems.
The measure would be best assessed on organisms found (or placed) in the
stressed environment so as to include not only the toxicant stress but also
response under natural conditions. Two measures were assessed in the mercury
contaminated Clear Lake, Lake County, California. Both utilized chronomid
larvae ( Chironomus plumosus ) a genus commonly found worldwide. The second
measure was further tested for potential correlation with allozyme
heterozygosity and the repeatabilty of the measure. The first examined allozyme
frequencies along a gradient of sediment mercury concentrations. We examined
whether allozyme frequencies could be used to distinguish populations along the
gradient or between contaminated and reference sites. No significant correlations
were found between allozyme frequencies and contamination, but an overall
deficit of heterozygotes was found at all sites sampled. While toxicant stress
could be the cause, a more parsimonious explanation would be sampling over a
patch population structure leading to a heterozygote deficiency (Wahlund
effect). Examination of allozyme frequencies along a transect indicated that
the observed deficiency of heterozygous genotypes was due to sampling across
some fine-scale substructuring of the populations. The second measure examined
the use of developmental stability as an indicator. Developmental stability is
the ability of an organism to produce a consistent phenotype in a given
environment. Measures of developmental stability, such as fluctuating asymmetry
and phenodeviation, provide a simple method for detecting stress in
populations. Fluctuating asymmetry is the deviation from perfect bilateral
symmetry in traits. Phenodeviants are aberrations from the normal phenotypic
expression of a character. Developmental stability was examined for chironomid
larvae collected along a gradient of sediment mercury concentrations. Four of
12 measures of fluctuating asymmetry differed significantly among sites.
Differences were correlated with mercury contamination. The frequency of
phenodeviants also showed differences among individuals from the three areas
examined. Finally, the midge larvae were assessed relative to a potential
relationship of these potential bioindicators to allozyme-heterozygosity.
Replicability of tested indices was examined. Asymmetries of the different
characters were uncorrelated. Fluctuating asymmetry and total heterozygosity
were significantly higher in the more contaminated site. However, no
significant relationship was found between the level of individual fluctuating
asymmetry and individual allelic heterozygosity.

California, Nevada
Abstract:
THIS IS THE ARTICLE
WASHINGTON,
March 21 -- The U.S. Department of the Interior's U.S. Fish & Wildlife
Service issued the following press release:
The
Department of the Interior today announced that 6 Native American conservation
projects in California and Nevada will receive $658,622 in grant funding
through the National Tribal Wildlife Grant Program administered by the U.S.
Fish and Wildlife Service. The grants provide technical and financial
assistance for the development and implementation of efforts that benefit fish
and wildlife resources and their habitat, including species that are not hunted
or fished.
Nationwide,
$6.2 million in grants will go to 38 Native American projects in 18 states to
fund a wide range of conservation projects.
"The
Tribal Wildlife Grants program has helped the Service to collaborate more
effectively with Native American tribes in conserving and restoring the vast
diversity of fish and wildlife habitat that they manage," said U.S. Fish
and Wildlife Service Director H. Dale Hall.
More
than $34 million has gone to Native American tribes through the Tribal Wildlife
Grants program in the past six years, providing funding for 175 conservation
projects administered by 133 participating Federally-recognized tribes. The
grants have enabled tribes to develop increased management capacity, improve
and enhance relationships with partners including State agencies, address
cultural and environmental priorities, and heighten interest of tribal students
in fisheries, wildlife and related fields of study. Some grants have been
awarded to enhance recovery efforts for threatened and endangered species.
The
grants are provided exclusively to Federally-recognized Indian tribal
governments and are made possible under the Related Agencies Appropriations Act
of 2002, and through a component of the State Wildlife Grant program.
During
the current grant cycle, tribes submitted a total of 110 proposals that were
scored by panels in each Service Region using uniform ranking criteria. A
national scoring panel recommended 38 proposals for funding.
The
conservation projects covered by the California and Nevada Tribal grants
include, in California: Three grants totaling $293,225 for projects addressing
the Clear Lake hitch, a culturally significant native fish in Clear Lake. This
multi-tribal effort will seek to accelerate the recovery of this fish and to
provide stock to other streams in the watershed. The three tribes and their
individual grant awards are: The Big Valley Rancheria Band of Pomo Indians in
California, $49,791 for the Big Valley Rancheria Clear Lake Hitch Study;
Habematolel Pomo of Upper Lake, $48,498 for the Clear Lake Hitch Study and
Recovery Project; and the Robinson Rancheria , $194,936 for the Clear Lake
hitch study.
A
grant to the Yurok Tribe of the Klamath River Reserve in northern California
for $200,000 to study the feasibility of reintroducing California condors to
the Yurok Ancestral Territory. The condor is listed as an endangered species by
Federal and State agencies.
A
grant to the Karuk Tribe for $100,000 for the Bluff Creek Habitat
Protection-Road Decommissioning Implementation Project will improve salmon
habitat by decommissioning a road that is a primary source of sedimentation
negatively impacting salmon spawning habitat.
In
Nevada the Moapa Band of Paiutes will receive $97,397 for the Muddy River
Habitat Enhancement Project (Stream Bank Restoration). This project will
restore and enhance the fishery and wildlife habitat of the Moapa River and
other important wetland habitats on the Moapa Indian Reservation. The Tribe
will restore stream channel and stream bank characteristics so that a riparian
component made up of native plants can be established.
The
mission of the U.S. Fish and Wildlife Service is working with others to conserve,
protect and enhance fish, wildlife, plants and their habitats for the
continuing benefit of the American people. We are both a leader and trusted
partner in fish and wildlife conservation, known for our scientific excellence,
stewardship of lands and natural resources, dedicated professionals and
commitment to public service. For more information on our work and the people
who make it happen, visit www.fws.gov [http://www.fws.gov].

Abstract:
In 1970, flood control levees extending 1,537 miles were operated under
cooperative state and federal agreements in the sacramento and san joaquin
valleys and in lake and placer counties, calif. flood control projects include
the sacramento, american, san joaquin, calaveras, and truckee rivers;
littlejohns and middle creeks; merced county stream group; sacramento river
bank protection project, and the lower san joaquin flood control project; and
the fresno county stream group. twice during 1970, department of water
resources specialists rated the quality of levee maintenance performed by local
maintaining agencies. this bulletin reports both the 1970 ratings and the
method of rating, discusses proper maintenance procedures, and reports levee
construction by the u. s. army corps of engineers, channel maintenance,
applications for levee encroachments, and the condition of the flood control
project structures. maps locate project levees and local maintenance agencies.

Abstract:
This dissertation addresses the impacts of nutrients, pesticides, algaecides
and introduced fish on the lake's plankton community. Nutrient addition
bioassays indicate that the growth of blue-green algae in Clear Lake is usually
directly limited by combined nitrogen. Nitrate stimulates growth and inhibits
nitrogen fixation, while phosphate additions usually have no effect on these
parameters. Low iron levels (2-30 mu g/L dissolved Fe) aggravate the effects of
low nitrogen by limiting nitrogen fixation (acetylene reduction). Nitrogen
fixation rates are stimulated as much as 500% above control levels by iron in
laboratory and in situ large-volume bioassays. Small additions of copper could
effect algal control in Clear Lake. At concentrations of 10-75 mu g/L, copper
significantly reduces blue-green algal carbon fixation, nitrogen fixation, and
biomass. At 2 mu g Cu/L there is a small but significant stimulatory effect,
especially on nitrogen fixation.

Abstract:
Copper toxicity bioassays were conducted on six stages of the spring
Aphanizomenon flos-aquae bloom in eutrophic Clear Lake, California. Major
variables tested were nitrogen fixation, carbon fixation, pigments, and cell
numbers. Inhibition of nitrogen fixation, carbon fixation, and pigment
accumulation increased linearly between 10 and 30 mu g Cu/L. Higher
concentrations produced little additional toxicity. In contrast, there was a
stimulatory effect of copper, especially on nitrogen fixation, at the very low
level of 2 mu g/L. There was no inhibitory effect of copper on nitrogen
fixation without a comparable or greater effect on carbon fixation or
chlorophyll a. Other algae growing with the Aphanizomenon bloom were not
affected by additions of copper up to 20-30 mu g Cu/L, but were affected at the
50-100 mu g/L level.

Abstract:
Clear Lake, California, is warm, shailow, polymictic, and eutrophic. During
1995, levels of dissolved (<0.45 prn) iron in all three basins of Clear Lake
were always low (1 5 - 30 pg a L- ' ) and decreased to 2 kg. L- ' during the
major bloom of Aphanizornenon flos-aquae. Nitrogen fixation (acetylene
reduction) rates of the blue-green algal populations were stimulated as much as
500% above control Bevels by iron additions in laboratory and in situ
large-volume bioassays. Carbon fixation rates and chlorophyll a Bevels were
also significantly stimulated by iron additions, but usually less rapidly and to
a lesser extent than N2 fixation. Additions of nitrate stimulated carbon
fixation and chlorophyli production but inhibited increases in nitrogen
fixation. Phosphate additions either had no effect or produced a mixture sf
stimulation or depression sf all three variables. The bioassays indicate that
the growth of blue-green algae and other algae in Clear Lake is usually
directly limited by combined nitrogen and occasionalEy by iron or phosphorus.
Low iron levels aggravate the effects of low nitrogen by limiting nitrogen
fixation, thus reducing blue-green algal growth.

Title: Diel migrations of a zooplanktivorous fish (Menidia beryllina) in
relation to the distribution of its prey in a large eutrophic lake
Abstract:
Diel changes in the distribution of the tidewater silverside (Menidia
beryllina) and its prey were measured in Clear Lake, California, a large,
shallow, eutrophic lake. Zooplankton prey densities were low in the littoral
zone, but increased rapidly to near peak abundances 50-200 m from shore. Gill netting,
trawling, and visual observations showed that tidewater silversides migrated
both horizontally and vertically to feed in areas of high zooplankton
abundance. At night the fish concentrated near shore and did not feed. At dawn
(8 x 10^8-2 x l0^10 photons cm^-2 nm^-1 s^-l) the fish migrated lakeward at
least 50-l,000 m, and littoral abundance decreased from more than 100 m^-2 to
only 0.1^-2. The migration preceded the initiation of feeding by 30-60 min.
After feeding 2-4 h, the fish returned to the littoral zone and swam rapidly
(6-11 body lengths s^-l) parallel to shore in narrow, continuous schools until
resting aggregations formed. The fish returned to shore before they were
satiated, perhaps to balance predation losses in offshore areas against foraging
gains. A second period of offshore activity and feeding occurred in the
afternoon and evening.

Abstract:
The bioaccumulation of mercury in fish is a function of several environmental
parame- ters. These parameters include, but are not limited to, water pH,
sediment mercury levels, and the nutrient level of the aquatic habitat. The
nutrient level, or trophic level, of the aquatic environment can be determined
as a function of total nitrogen availability of bottom sediments, total
phosphorous availability of the water columns, and algal pro- duction. These
parameters were used to determine the trophic level index, or bioproduc- tion
index (BPI), for Clear Lake in northern California. The water pH, sediment
mercu- ry levels, and bioproduction index for Clear Lake were incorporated into
a quantitative model to determine the methylmercury bioaccumulated in
largemouth bass (Micropterus salmoides). Fish methylmercury levels based on the
Clear Lake BPI are also determined for decreasing sediment mercury levels,
which would occur following the implementation of mercury amelioration
procedures. Tissue mercury concentrations in largemouth bass taken from Clear
Lake are compared to the derived fish mercury values. Predicted fish
methylmercury concentrations closely correspond to observed tissue mercury
concentra- tions taken from largemouth bass at Clear Lake. Based on these
parameters, it is deter- mined that a 95% reduction in sediment mercury levels
in the Oaks Arm is required to reduce fish mercury concentrations to the
recommended FDA guideline of 1 pg/ g, and a 99% reduction in sediment mercury
levels is required to produce fish mercury concentra- tions at the NAS
guideline of 0.5 p.g/l.

Abstract:
The range of splittail Pogonichthys macrolepidotus has decreased to less than a
third of its original range due to loss or alteration of habitats. We measured
the critical thermal minima (CT min) and maxima (CT max), critical dissolved
oxygen minima (CDOmin). critical salinity maxima (CSmax). salinity endurance,
and critical swimming velocity (Ucrit) for age-O (0.1-4.0 g), age-l (10-48 g),
and immature age-2 (72-201 g) splittails to assist in effective water and
habitat management and restoration of this species. Neither thermal acclimation
nor fish weight affected the CTmin (6.5-7.3°C), but CTmax (29-33°C) of fish
acclimated at 17 and 20°C were higher than CTmax (21-22°C) of fish acclimated
at 12°C. Mean CDOmin values were low (0.6-1.3 mg 02/L) for all age groups,
although immature age-2 fish acclimated at 12°C had a lower CDOmin than any
group acclimated at 17°C. Mean CSmax (20-29%0) did not vary with acclimation
temperature, but increased with increasing weight for fish acclimated at 17°C.
Mean time to loss of equilibrium in all age-groups generally decreased as
salinity increased and was generally lower for age-O fish than for those of
other age-groups. Mean absolute Ucrit (19.5-66.3 cm/s) increased with standard
length (SL), but relative Ucrit (3.4-6.8 body lengths/s) decreased with SL for
fish acclimated at 17°C. Increases in acclimation temperature by 3°C for small
age-O fish and 5°C for age-2 fish increased absolute Ucrit by 11 and 25 cm/s,
respectively. We conclude that age-O. age-1, and especially age-2 fish are
eurythermal. euryhaline, and tolerant of low DO levels and strong water
currents. This general hardiness probably permits splittails to exist in harsh
estuarine habitats such as dead end sloughs. A lack of sufficient flooded
vegetation for spawning and rearing, narrower environmental tolerances of other
life stages (i.e., eggs, larvae, and adult spawners), or biotic factors (e.g.,
predation, competition) may be limiting splittail abundance and distribution.
