Abstract – As described in East Bay Municipal Utility District’s Water Quality and
Resource Management Program, twenty-two water quality constituents were monitored at
six locations in Camanche Reservoir and the lower Mokelumne River over a 55-month
period beginning in December 1999. None of the constituents monitored exceeded the
numerical water quality limits recommended by the California Regional Water Quality
Control Board, Central Valley Region except for concentrations of copper and zinc, and
measures of dissolved oxygen and pH. It is recommended that monitoring of copper,
zinc, dissolved oxygen, pH, temperature and total hardness continue in the lower
Mokelumne River below Camanche Dam and the remaining constituent sampling
program be discontinued.
INTRODUCTION
The Water Quality and Resource Management Program (Program) was developed as part
of the Joint Settlement Agreement for East Bay Municipal Utility District's (EBMUD)
Lower Mokelumne River Project. The Program, designed in partnership by EBMUD, the
California Department of Fish and Game, and the U.S. Fish and Wildlife Service, has 16
specific implementation measures, each with one or more performance criteria.
Four performance criteria identified in the Program focus on water quality:
• Continue monitoring CAMC and CAMD in Camanche Reservoir to measure
temperature, pH, dissolved oxygen, conductivity, oxidation-reduction
potential, and turbidity. In addition, collect monthly water quality samples at
CAMC and CAMD to analyze for volatile suspended solids (VSS), total
suspended solids (TSS), nutrients (total and dissolved phosphorus and

nitrogen), chlorophyll (corrected and uncorrected for phaeopigments), and
phytoplankton and zooplankton abundance and taxonomic composition (to
genus).
• Collect monthly water quality samples in the lower Mokelumne River at the
Elliott Road Bridge to analyze for VSS, TSS, nutrients (total and dissolved
phosphorus and nitrogen), chlorophyll (corrected and uncorrected for
phaeopigments), and phytoplankton and zooplankton abundance and
taxonomic composition (to genus). In addition, the samples are analyzed for
hardness, Al, Cd, Cr, Cu, Fe, Ni, Pb, Zn, Hg, Ti, pH and turbidity.
• Collect monthly water quality samples at CAMA and PENN20 in Camanche
Reservoir to analyze for TSS, hardness, Al, Cd, Cr, Cu, Fe, Ni, Pb, Zn, Hg,
Th, pH, and turbidity.
• Monitor temperature, pH, dissolved oxygen, conductivity, oxidation-reduction
potential, total and volatile suspended solids, total and dissolved
phosphorous and nitrogen, and turbidity of the Mokelumne River Fish
Hatchery water supply and effluent.
This report describes the methods and results of the water quality monitoring conducted
from December 1999 through June 2004.
METHODS
Samples were collected monthly and analyzed for the appropriate constituents by
EBMUD water quality staff. Sample collection locations are shown in Figure 1. During
reconstruction of the Mokelumne River Fish Hatchery or when the raceways were
dewatered, no samples were collected or analyzed at CAFH01 and CAFH02. Measures
of total hardness were not collected at DEPTH PENN20 for the months October 2003
through March 2004, so the lowest value measured during the monitoring period
(December 1999 through June 2004) was used to determine numerical water quality
limits for cadmium, chromium, copper, lead, nickel, and zinc.

The California Environmental Protection Agency’s and Regional Water Quality Control
Board’s (Central Valley Region) A Compilation of Water Quality Goals (Marschack
2003) lists numerical water quality limits to protect freshwater aquatic life. That report
and The Water Quality Control Plan (Basin Plan) for the California Regional Water
Quality Control Board, Central Valley Region (CRWQCB 1998) provide context (Table
1) for the numerical results reported here but are not regulatory limits.
RESULTS
Aluminum
As with most metals the speciation (the molecular form of atoms of an element or a
cluster of atoms of different elements in a given matrix) of aluminum (Al) is based on the
pH of the water. As the pH of water decreases (acidity increases) the amount of Al as
Al 3+ increases. Al 3+ is the form of aluminum toxic to fish. At neutral pH (7.0) and
nominal hardness levels aluminum is less toxic to fish. The mechanism for impact to fish
by Al is in the form of branchial ionic regulation (ion regulation at the gills). As Al 3+
increases, sodium levels in fish decrease presumably due to the inhibition of Na-K-
ATPase at the gills (Staurnes et al. 1984). In hard waters (high CaCOB3B
concentrations) with pH

within aquatic systems can lead to algal blooms. Algal blooms and increased macrophyte
production can lead to eutrophication, lowered over-night dissolved oxygen levels and
associated problems. Ammonia continually changes to ammonium (NH 4+ ) and vice
versa, with the relative concentrations of each depending on the water's temperature and
pH. Ammonia is extremely toxic; ammonium is relatively harmless. At higher
temperatures and pH, more of the nitrogen is in the toxic ammonia form than at lower
pH.
No ammonia concentrations exceeded the recommended numerical limits in Table 1.
Concentrations ranged from below minimum detection limits to 0.18 mg/L (CAFH02,
May 2004) (Appendix A).
Cadmium
Water hardness and pH values determine speciation of cadmium (Cd) in water. At a pH
of 5.0 Cd exists as Cd 2+ , while at pH of 7.5 it exists mainly as CdOH + . In the pH range
between 5.0 and 7.5 what portion of Cd exists as Cd 2+ is affected by water hardness and
the amount of organic matter within the system.
The impact mechanism of Cd varies. Cadmium induced anemia in fish is caused by
deformities of red and white blood cells (Heath 1995). In adult Atlantic salmon (Salmo
salar) concentration of 3.6 µg/L Cd over 178 days did not produce any changes in ionic
balance (Giles 1984). However, it is known that Cd accumulates in kidneys and gills,
even when exposure is through food. Cadmium seems to impair the ability of fish to
uptake ionic calcium from the environment through the gills (Rombough and Garside
1984). Calcium uptake can also be impacted by kidney damage resulting from Cd
exposure. Ultimately the continued reduction of Ca + in the blood leads to death.
Juvenile fish are more affected by the loss of ionic calcium than adult fish.
No cadmium concentrations exceeded the recommended numerical limits in Table 1.
Concentrations ranged from below minimum detection limits to 0.36 µg/L (BOTT
4

CAMA, June 2003) (Appendix A). The minimum detection limit on eight samples
exceeded the recommended numerical limits (Appendix A).
Chlorophyll
The concentration of chlorophyll is a measure of the plant life suspended in the water
column. There are several kinds of chlorophyll, the most important being chlorophyll
"a". This is the molecule that makes photosynthesis possible, by passing its energized
electrons on to molecules that will manufacture sugars. All plants, algae, and
cyanobacteria that photosynthesize contain chlorophyll "a". A second kind of chlorophyll
is chlorophyll "b", which occurs only in "green algae" and in the plants. A third form of
chlorophyll is chlorophyll "c", and is found only in the photosynthetic members of the
Chromista as well as the dinoflagellates. Phaeophyton is a chlorophyll degredation
product (i.e., dead stuff) often found in high quantities during and after an algal bloom
occurs. Phaeophyton may be an indicator of the past history of the phytoplankton
population in the water column. Phaeophyton can be formed when phytoplankton cells
remain in dark conditions, by bacterial action and the passage of phytoplankton cells
through the gut of zooplankton organisms. Samples were analyzed for Chlorophyll a and
Chlorophyll a corrected for phaeophyton.
There are no recommended numerical criteria for chlorophyll concentrations.
Chlorophyll a concentrations ranged from below minimum detection limits to 18 µg/L
(MS ELLIOTT, January 2002). Chlorophyll a corrected concentrations ranged from
below minimum detection limits to 12 µg/L (MS ELLIOTT, January 2002) (Appendix
A).
Chromium
The hexavalent form of chromium (Cr VI) is more toxic to aquatic organisms than the
trivalent form (Cr III). Generally chromium is not very toxic to fish but chromium is
more toxic to salmonids than to non-salmonids. The mechanism of impact for chromium
is not clear. Hexavalent Cr passes easily through biological membranes and is then easily
converted to trivalent Cr. Coho salmon exposed to Cr concentrations of 200 µg/L to 500
5

µg/L did not exhibit outward signs of stress. However, when challenged in saltwater
tests, those fish exposed to Cr suffered high rates of mortality (Sugatt 1980). Chromium
can also affect oxygen consumption by increasing an organism’s spontaneous movement.
Bluegill exposed to increasing concentrations of Cr (III) (50 µg/L to 24,000 µg/L)
exhibited increased amount of spontaneous movement (Heath 1995). There is also
evidence that chromium can affect glucose metabolism in trout. At a concentration of
200 µg/L rainbow trout showed depletions in glucosides (Arillo et al. 1982).
Bioaccumulation of Cr is not evident in salmonids, but is evident in bluegill.
No chromium concentrations exceeded the recommended numerical limits in Table 1.
Concentrations ranged from below minimum detection limits to 6.11 µg/L (SURF
CAMA, February 2003) (Appendix A).
Conductivity
Conductivity is a measure of the ability of water to conduct an electrical current. The
presence of metallic ions, inorganic acids, bases and salts result in high conductivity.
Conductivity is usually measured in micromhos per centimeter (µmhos/cm).
Conductivity in and of itself does not directly impact aquatic life, as different life forms
(stages) are adapted to various levels of conductivity. Typically, freshwater has a lower
conductivity than seawater.
There are no recommended numerical criteria for conductivity. Conductivity ranged
from 0.021 (CAMD, April 2001) to 0.055 µmhos/cm (CAFH02, April 2002) (Appendix
A).
Copper
As with most metals the speciation of copper (Cu) in water is dependent on pH and water
hardness. Below a pH of 5.0 copper exists as Cu 2+ ; while at pH of 7.5 Cu exists as
CuCO 3 with some Cu + . Between the pH of 5.0 and 7.5 the level of Cu 2+ increases as the
pH decreases. Water hardness plays a key role in speciation of copper. As water
hardness decreases the conditions for formation of Cu 2+ increases. Copper has a high
6

affinity to bind with suspended solids or organic matter, which results in lower toxicities
when these parameters are elevated (Heath 1995).
At low water hardness levels and low pH fish gills readily absorb copper. Moreover,
copper easily passes through cell membranes. In fish, copper tends to accumulate mainly
in the liver, while some builds up in the gills. Copper has been shown to have impacts on
the ability of fish to osmoregulate and the cause of death from lethal doses of copper is
ionoregulatory collapse (Wilson and Taylor 1993). The specific mechanism for death
appears to be inhibition of sodium and chloride uptake by the gills (McDonald et al.
1988). Fish are able to acclimate to sub-lethal concentrations of copper, which make
them better able to tolerate higher doses (Buckley et al. 1982).
Depending on sample location, copper concentrations exceeded the recommended
numerical limits in Table 1 in 38 samples; the minimum detection limit on 206 samples
exceeded the recommended numerical limits; and samples for dissolved copper were not
collected/analyzed from October 2003 through May 2004 at DEPTH PENN20 (Appendix
A).
Dissolved Oxygen
The amount of dissolved oxygen (DO) in water is based on a combination of pressure,
water temperature and salinity. Generally the warmer the water the harder it is to get
oxygen to dissolve. Low dissolved oxygen levels do not impact warm water fish species
such as minnows, catfish and carp. In fact, these fish have evolved to take advantage of
low oxygen conditions. However, in situations with high nutrient input or aquatic
vegetation populations the biological oxygen demand (BOD) can exceed the dissolved
oxygen available. Healthy aquatic systems generally have BODs that do not exceed 5.0
mg/L.
Cold water fish species, such as salmon and trout, are sensitive to DO levels below 5.0
mg/L. Sensitivity to lowered oxygen levels is greater in larval salmonid fry. Hatching
7

delays and smaller fry are observed when salmonid eggs are exposed to 2-3 mg/L. DO
levels within gravel are generally lower than those measured within the water column.
Sub-optimal levels of oxygen can result in adverse impacts to fish including build up of
lactic acid, hypoxia, increased respiration and energy demands, and decreased
performance.
Dissolved oxygen concentrations exceeded the recommended numerical limits in Table 1
in 68 samples (Appendix A).
Hardness (Total)
Total hardness is the measure of the total concentration of divalent metal ions (primarily
calcium and magnesium) expressed in milligrams per liter of equivalent calcium
carbonate (CaCO 3 ). Total hardness is related to total alkalinity and indicates the potential
for stabilizing pH. The importance of hardness relates to its ability to vary toxicity of
metals and pH. Increased hardness levels decrease the toxicity of many of the heavy
metals and of acidic pH levels. Fish do best when total hardness measures between 20
and 300 mg/L (Johnson 1985).
There are no recommended numerical criteria for total hardness. Hardness ranged from
10 mg/L (DEPTH PENN20 and SURF CAMA, December 1999) to 28 mg/L (BOTT
CAMA, August 2002).
Iron
Iron (Fe) is less toxic to fish than many of the metals. The cause of death from lethal
concentrations of iron appears to be precipitates forming on gill tissues and reducing gill
function.
None of the samples for iron concentrations exceeded the recommended numerical limits
in Table 1. Concentrations ranged from below minimum detection limits to 468 µg/L
(BOTT CAMA, February 2000) (Appendix A).
8

Lead
At a pH range of 4.0 to 5.0 lead (Pb) exists as Pb 2+ , while at pH>5.0 lead exist as PbCO 3
and Pb 2+ . One of the effects of lead is the inhibition of hemoglobin synthesis. Trout
exposed to various levels of lead exhibited anemia at a concentration of 300 µg/L (Heath
1995). However, decreases in the enzyme necessary for the production of hemoglobin
(ALA-D) were detected at 10 µg/L. Lead appears to have some minor effects on sodium
and calcium regulation in the body. Bioaccumulation of lead does not involve
accumulation in muscle tissue.
No lead concentrations exceeded the recommended numerical limits in Table 1.
Concentrations ranged from below minimum detection limits to 13.7 µg/L (DEPTH
PENN20, May 2004); the minimum detection limit on four samples (BOTT CAMA,
December 1999, January 2000; SURF CAMA, December 1999; MS ELLIOTT, January
2000) exceeded the recommended numerical limits; and, samples for lead concentrations
were not collected/analyzed for DEPTH PENN20 in July and August 2001 (dissolved),
and MS ELLIOTT and SURF CAMA in August 2002 (dissolved and total) (Appendix
A).
Mercury
Mercury (Hg) exists within aquatic environments in inorganic and organic
methylmercury forms. Aquatic organisms absorb mercury through water contact and via
dietary routes. As water hardness and pH decrease, mercury toxicity increases. There is
also a synergistic effect between inorganic mercury and methylmercury. Uptake of
methylmercury increases as inorganic mercury levels increase (Rogers and Beamish
1983).
Methylmercury is many times more toxic to aquatic organisms than inorganic mercury.
Mercury impacts the ability of fish to osmoregulate, which ultimately causes death at
lethal concentrations. Blood sodium levels dropped 40% in trout exposed to lethal
concentrations of inorganic mercury (Lock et al. 1981). An additional mode of impact is
9

through bioaccumulation of methylmercury. Invertebrates accumulate greater amounts of
Hg relative to body size. Therefore, top predators in the aquatic food chain tend to
accumulate mercury at the highest levels. Methylmercury can accumulate ten times
faster than inorganic mercury when contained in the diet. Moreover, elimination of
methylmercury is much slower than inorganic forms. Toxicity from bioaccumulated
organic mercury does not occur until levels reach or exceed 10-30 µg/g within tissues
(Spry and Wiener 1991).
None of the samples for mercury concentrations exceeded the recommended numerical
limits in Table 1. Concentrations ranged from below minimum detection limits to 0.33
µg/L (SURF CAMA, June 2004) (Appendix A). Samples for mercury concentrations
were not collected/analyzed for BOTT CAMA and DEPTH PENN20 in December 1999,
MS ELLIOTT in July 2000, and SURF CAMA in December 1999 and February 2000.
Nickel
Nickel (Ni) is always present as NiP2+P in waters ranging from 4.0 to 9.0 pH. In natural
unpolluted waters within the USA nickel concentrations range from 3 to 17 µg/L. Nickel
is known to cause damage to gill surfaces and inhibits ATP-ase activity (Calamari 1994).
Carp exposed to near lethal levels of nickel exhibited decreased protein metabolism.
No nickel concentrations exceeded the recommended numerical limits in Table 1.
Concentrations ranged from below minimum detection limits to 7.23 µg/L (MS
ELLIOTT, August 2001); and, samples for nickel concentrations were not
collected/analyzed for DEPTH PENN20 in December 1999 (total), and MS ELLIOTT
and SURF CAMA in August 2002 (Appendix A).
Nitrate
The nitrogen cycle is one of the more complex cycles occurring in aquatic systems.
Nitrogen can be present in various forms within water including dissolved nitrogen gas
(N 2 ), nitrate (NO 3- ), nitrite (NO 2- ) and ammonia (NH 3 ). The sum of all of the nitrogen
forms is referred to as total nitrogen. Nitrogen enters water through various inputs
10

including atmospheric gas, geologic sources, bacterial production, animal wastes and
fertilizers. Nitrogen is a vital nutrient to both animals and plants, however, excesses
within aquatic systems can lead to algal blooms. Algal blooms and increased macrophyte
production can lead to eutrophication, lowered over-night dissolved oxygen levels and
associated problems. Nitrate is generally nontoxic to fishes and can be expected to occur
at less than 2 mg/L in natural surface waters. Fish can tolerate several hundred mg/L of
nitrate.
There are no recommended numerical criteria for nitrate concentrations. Nitrate
concentrations ranged from below minimum detection limits to 0.11 mg/L (BOTT
CAMD, April 2002) (Appendix A). No samples were analyzed for nitrate at SURF
CAMD from December 1999 to August 2000.
Nitrite
Nitrite, which is one of the basic breakdown products of organic matter decomposition
acts as an intermediate stage in the conversion of ammonia to nitrate. It is changed
quickly to nitrate if oxygen is present.
Nitrite is the form of nitrogen that is toxic to aquatic species. The reduction of nitrate or
the oxidation of ammonia forms nitrite. Nitrite enters into the bloodstream of fish via the
chloride cells within the gills. Within the blood it oxidizes the iron in haemoglobin into a
trivalent form that does not react with oxygen (it does not pick up oxygen and release it
into tissues). The mechanism of death is hypoxia. Fish, such as salmonids, that have a
high density of chloride cells within their gills are more susceptible to nitrite. The 4-day
LC 50 value of nitrite for steelhead trout ranged from 0.5 to 12.1 mg/L (Wedemyer and
Yasutake 1978).
Acclimation to increased levels of nitrite has been exhibited by fish in a number of
studies (Eddy and Williams 1994). Fish eggs, fry and juveniles are generally more
tolerant of nitrite than adults. Rainbow trout fingerlings were reported to have an 24-
11

hour LC 50 value of 1.6 mg/L nitrite, while adults had a LC 50 value of 0.96 mg/L (Smith
and Williams 1974).
There are no recommended numerical criteria for nitrite concentrations. Nitrite
concentrations ranged from below minimum detection limits to 0.007 mg/L (CAFH02,
September 2000) (Appendix A). No samples were analyzed for nitrate at SURF CAMD
from December 1999 to August 2000.
Orthophosphate and Total Phosphate
As with nitrogen, phosphorous is a vital nutrient to aquatic life, especially plants. Orthophosphates
are the most biologically accessible form of phosphorous. Other forms
include elemental phosphorous and phosphine. Excess phosphorous within an aquatic
system leads to eutrophication and lower overnight dissolved oxygen levels.
There are no recommended numerical criteria for orthophosphate or total phosphate
concentrations. Orthophosphate concentrations ranged from below minimum detection
limits to 0.048 mg/L (CAFH02, April 2001) (Appendix A). Total phosphate
concentrations ranged from 0.007 mg/L (SURF CAMD, July 2001) to 0.11 mg/L
(CAFH02, September 2000).
Oxygen Reduction Potential
The oxidation-reduction potential (ORP) of water is also known as redox. It is a physical
measure of the potential of oxidation or reduction reactions to occur and is usually
reported in millivolts (mV). ORP values have no direct impacts to aquatic organisms.
But, low ORP values allow for the formation of metal species that can impact aquatic
organisms.
There are no recommended numerical criteria for oxygen reduction potential. Oxygen
reduction potential ranged from 298 mV (CAFH01, July 2003) to 689 mV (CAMD,
January 2003) (Appendix A).
12

pH
The term pH is associated with the degree of acidity or alkalinity of water. However, pH
is actually a measure of the level of hydrogen ion activity. The pH of waters can play an
important role in the speciation and bioavailability of various metals. The lower the pH
levels the higher the acidity and the greater toxicity of metals to aquatic organisms. For
most aquatic organisms a pH level of 6.5 to 8.5 (Basin Plan criterion) is considered
optimal. Maximum biological productivity is achieved in a pH range of 6.5 to 8.5, while
pH values between 5.0 and 9.0 are considered safe (Alabaster and Lloyd 1982, Piper et
al. 1982). The direct lethality of lower pH results from liberation of carbon dioxide from
water that results in the suffocation of fish and aquatic invertebrates. Sub-lethal effects
of pH include inhibition of ionic regulation and damage to gill surfaces. With many
pollutants, low pH increases their toxicity. Low pH values can decrease the amount of
nutrients within a system, thereby reducing the population of invertebrates. Aquatic
invertebrates can generally withstand lower pH values down to 3.0, which is lower than
the level lethal to fish.
The pH values exceeded the recommended numerical limits in Table 1 in 28 samples
(Appendix A).
Plankton
Plankton refers to the collection of small or microscopic organisms, including algae and
protozoa that float or drift in great numbers in fresh or saltwater, especially at or near the
surface, and serve as food for numerous organisms including fish.
Plankton sampled in Camanche Reservoir and the lower Mokelumne River are grouped
as chlorophyceans, crustacea, cyanobacteria, diatoms, dinoflagellates, euglenoids,
protozoa, and rotifers and results are presented in Appendix A. There are no
recommended numerical criteria for plankton.
13

Chlorophyceae
The sheer diversity of chlorophyceans, a green algae, in freshwater has impressed
ecologists interested in the roles of biotic diversity and functional redundancy in
community and ecosystem stability. Scenedesmus and Pediastrum, among the most
common members of the freshwater green plankton, have fossil records and are
implicated in formation of certain oil deposits. The following genera were identified in
samples taken in Camanche Reservoir and the lower Mokelumne River; Amphicampa,
Ankistrodesmus, Bulbochaete, Closterium, Coelastrum, Cosmarium, Crucigenia,
Elakatothrix, Eudorina, Gloeocystis, Golenkinia, Hormidium, Mougeotia, Nephrocytium,
Oocystis, Palmella, Pandorina, Pediastrum, Quadrigula, Scenedesmus, Schroederia,
Sphaerocystis, Spriogyra, Spondylosium, Staurastrum, Tetraedron, and Ulothrix.
Chrysophyceae
Chrysophyceans can exert significant ecological influence in oligotrophic lakes. Because
they leave siliceous remains in lake sediment, they are widely used as ecological
indicators in studies of past and present environmental change. Chrysophyceans typically
favor slightly acid, soft (low alkalinity and conductivity) waters of moderate to low
productivity. Species of Mallamonas (as well as other chrysophyceans) contribute to
odor and taste problems in water supplies. The following genera were identified in
samples taken in Camanche Reservoir and the lower Mokelumne River; Dinobryon,
Mallomonas, and Synura.
Crustacea
Crustaceans have evolved into several major groups which represent distinct
modifications for exploiting resources in many different habitats. The cladocerans and
copepods together constitute the dominant component of most freshwater planktonic
communities. Crustacean zooplankton are major consumers of phytoplankton and some
crustaceans are predatory on rotifers, protozoans, other crustaceans and fish larvae.
Crustaceans were not identified to genera.
14

Cyanobacteria
Cyanobacteria, also known as blue-green algae, is the only algae known to be capable of
transforming molecular nitrogen gas into ammonia, which can then be assimilated into
amino acids, proteins, and other nitrogen-containing cellular constituents. Cyanobacteria
collected in Camanche Reservoir and the lower Mokelumne River include the following
genera; Agmenellum, Anabaenopsis, Anacystis, Anabaena, Aphanizomenon,
Coccochloris, Gomphosphaeria, Nodularia, and Oscillatoria.
Diatoms
Diatoms are probably the most numerous eukaryotic aquatic organisms and are among
the most important aquatic photosynthesizers in terms of global primary productivity.
Greenberg (1964) found that diatoms comprised 75% of the phytoplankton counts in the
Sacramento River. The following genera were identified in samples taken in Camanche
Reservoir and the lower Mokelumne River; Achnanthes, Amphirora, Amphora,
Asterionella, Attheya, Ceratoneis, Cocconeis, Cyclotella, Cymbella, Diatoma, Fragilaria,
Frustulia, Gomophonema, Gyrosigma, Hantzschia, Melosira, Meridion, Navicula,
Nitzschia, Pinnularia, Rhizosolenia, Rhopalodia, Stephanodiscus, Surirella, Synedra,
Tabellaria, and Ursolenia.
Dinoflagellates
There are about 220 freshwater species of dinoflagellates. The most prominent are the
photosynthetic Peridium and Ceratium, which occur in high calcium-ion, low nutrient,
and low pH waters. Freshwater dinoflagellates overwinter (and in some cases
oversummer) as benthic cysts. They also are important food sources for large protozoa,
rotifers and planktivorous fish. The genera Peridium, Ceratium, and Gymnodinium have
been identified in samples collected in Camanche Reservoir and the lower Mokelumne
River.
Euglenoids
Euglenoids are generally found in environments where there is an abundance of decaying
organic matter. It is estimated that there are more than 40 genera of euglenoids. Two
15

genera, Phacus and Trachelomonas, (as well as unidentified genera of euglenoids) have
been identified in samples collected in Camanche Reservoir and the lower Mokelumne
River.
Protozoa
All protozoa are single-celled organisms, though many species form colonies consisting
of several to thousands of individuals. They occur in an extraordinary variety of habitats
wherever there is water. In general, waters that contain a large number of microhabitats,
such as ponds, pools, rivers and streams contain the greatest number of species but not
necessarily the greatest number of individuals. Although local distribution of protozoan
is governed by such factors as light, temperature, food, dissolved oxygen,
acidity/alkalinity, and chemical substances, ecological generalizations can only be based
on species (Pennak 1989). Organisms collected in samples in Camanche Reservoir and
the lower Mokelumne River and grouped as protozoa include Class Heliozoa; Genera
Aulomonas, Cladomonas, Bicosoeca (= Codomonas, = Domatomonas), Codonella,
Tintinnopsis, and Vorticella.
Rotifers
The Phylum Rotifera occurs in an extreme variety of freshwater habitats, although
approximately 75% of the known species occur in the littoral areas of lakes and ponds.
Most planktonic communities average between 40 and 500 rotifers per liter with
populations in excess of 1000 per liter being unusual (Pennak 1989). Rotifers were not
identified to genera.
Temperature
Temperature is controlled by a variety of factors including ambient air temperature,
source of water and impoundments. It is also an important parameter in terms of fish
health. Dissolved oxygen is affected in part by water temperature.
Optimal temperature ranges for fish vary by species. Generally optimal temperatures for
warm water species (bass, catfish, minnows) range from approximately 15ºC to 25ºC,
16

while coldwater species (salmon, trout) range from 5ºC to 16ºC. Among the fish species
inhabiting the lower Mokelumne River, chinook salmon and steelhead, have the greatest
exposure sensitivity to elevated water temperatures. Chinook salmon and steelhead are
anadromous species that have evolved and adapted to cold-water conditions. Exposure of
these species to seasonally elevated water temperatures within the Sacramento-San
Joaquin river systems and the lower Mokelumne River has been identified as a major
stressor by CALFED (1997), State Water Resources Control Board (SWRCB 1991), U.S.
Environmental Protection Agency (EPA 1994), U.S. Fish and Wildlife Service (USFWS
1992, 1995; Castleberry et al. 1993), and California Department of Fish and Game (Rich
1997).
Each life stage of chinook salmon and steelhead has different physiological responses to
water temperature. These responses may reflect chronic and sub-lethal effects, such as
changes in development rate, growth rate or condition, or they may be acute effects
resulting in the loss of equilibrium and ultimately mortality (Rich 1997, Schreck 1982,
Brett 1971, Boles 1982, Sullivan et al. 2000). The thermal tolerance response of each life
stage varies in response to a number of factors including (1) acclimation temperature, (2)
the absolute exposure temperature, (3) the duration of exposure to elevated temperature,
and (4) the overall health and condition of the organisms (Hanson 1997).
Eaton et al. (1995) studied the upper temperature limiting salmonid distribution. Their
threshold is 24.0ºC for Chinook salmon and steelhead. Sullivan et al. (2000) developed a
risk-based approach to analyze summertime temperature effects on juvenile salmon
species. Acute risk to high temperatures was assessed using laboratory-derived values of
mortality in relation to duration of exposure. Their analysis suggested that there is little
or no risk of acute mortality if annual maximum temperature is less than 26ºC.
The State Water Resources Control Board 1991 Water Quality Control Plan recognized
an upper threshold temperature objective for protection of fall-run chinook salmon at a
daily average of 20ºC during the spring (April through June). Baker et al. (1995)
analyzed the results of U.S. Fish and Wildlife Service studies of juvenile chinook salmon
17

in the Sacramento River and predicted that temperatures of 20.0, 22.8 and 26.1ºC resulted
in 10, 50 and 90 percent mortality, respectively. Hanson (1997) concluded that stressful
temperature conditions for juvenile chinook salmon and steelhead rearing in the lower
Mokelumne River were considered to occur within the range of 16.1 to 20ºC.
Sullivan et al. (2000) suggests that quantitative analysis of growth effects can be applied
at specific sites or on a regional scale to identify appropriate risk-based chronic
temperature thresholds. Their research indicated less than a 20% reduction in growth
when coho salmon were exposed to temperatures of 9.0 to 20.5ºC (maximum 7-day
average temperature) and when steelhead were exposed to temperatures of 10.0-24ºC.
Temperature impacts to invertebrates are generally similar to juvenile fish. Increased
temperatures lead to accelerated development and early transformation to adult life
stages. Tendipedid larvae development rates increased threefold with a temperature
increase from 15ºC to 25ºC (Alabaster and Lloyd 1982). Alteration in natural cycles of
invertebrate development could impact the food base of the river ecosystem.
There are no recommended numerical criteria for water temperature. Average water
temperatures ranged from 9.06ºC (CAFH02, February 2002) to 18.6ºC (CAMD,
September 2003) (Appendix A).
Thallium
Thallium (Th) is a soft metallic element that becomes bluish-gray when exposed to air. It
is a member of the aluminum family of metals. It occurs in combination with pyrites, zinc
blende, and hematite. Thallium sulfate, which is odorless, tasteless, and very poisonous,
is used to exterminate rodents and ants. It can also be released into the environment from
industrial sources. Atmospheric thallium contaminates surface soils by deposition
following for the exposure of humans by oral, dermal, or inhalation routes.
The primary targets of thallium toxicity are the nervous, integumentary, and reproductive
systems. Human and animal chronic exposures result in alterations of the brain, spinal
18

cord, and peripheral nerves. In both humans and other mammals, alopecia (hair loss) is
the most common indicator of long-term thallium poisoning.
None of the samples for thallium concentrations exceeded the recommended numerical
limits in Table 1. Concentrations ranged from below minimum detection limits to 2.23
µg/L (DEPTH PENN20, September 2003) (Appendix A). Samples for thallium
concentrations were not collected/analyzed for BOTT CAMA in September 2003;
DEPTH PENN20 in December 1999; MS ELLIOTT in August 2002 and September
2003; and SURF CAMA in August 2002.
Total Suspended Solids and Turbidity
Total suspended solids (TSS) are the evaporated, unfiltered residue of a water sample and
may impede natural food production in a stream when concentrations exceed 250 mg/L
and may interfere with reproduction of some fishes at concentrations of 500 mg/L.
Eroded soil, streambed material, organic matter and other material are all components of
the total suspended solid (TSS) parameter. TSS can be measured as mg/L or as a
turbidity value (NTU). Total suspended solids (TSS) concentrations and turbidity both
indicate the amount of solids suspended in the water, whether mineral (e.g., soil particles)
or organic (e.g., algae). However, the TSS test measures an actual weight of material per
volume of water, while turbidity measures the amount of light scattered from a water
sample (more suspended particles cause greater scattering). This difference becomes
important when trying to calculate total quantities of material within or entering a water
body. Such calculations are possible with TSS values, but not with turbidity readings.
TSS concentrations are reported in units of milligrams of suspended solids per liter of
water – mg/L. Turbidity is reported as nephelometric (NTU) units.
TSS and resulting turbidity can affect fish feeding ability especially in sight feeders.
Juvenile coho salmon and steelhead were found to feed less and grow slower in waters
with turbidity levels of 23 to 192 NTUs (Sigler et al. 1984). Besides feeding, there may
be sub-lethal effects of TSS related to physiological stress. Salmonids exposed to two
levels of TSS, high (2-3 g/l) and low (0.2-0.3 g/l), exhibited increased cortisol levels
19

(stress) (Redding et al. 1987). Yearling steelhead exposed to the high concentration
showed an increased susceptibility to bacterial infection. Lethal (96-hour LCB50B) TSS
values ranged from 488 mg/L for chinook salmon to 1,200 mg/L for coho salmon (Lloyd
1987).
There are no recommended numerical criteria for turbidity or total suspended solids.
Total suspended solids ranged from below minimum detection limits to 12 mg/L (BOTT
CAMA, August 2003). Turbidity ranged from 0.05 NTU’s (SURF CAMD, July 2002
and SURF CAMA, April 2003) to 15.7 NTU’s (BOTT CAMA, February 2000). No
measurements were taken at BOTT CAMD, December 2003; DEPTH PENN20,
December 1999 and March 2000; and, SURF CAMD, December 2003 (Appendix A).
Volatile Suspended Solids
Volatile suspended solids (VSS) are those solids lost on ignition (heating to 500ºC). They
give a rough approximation of the organic matter present in the total solids.
There are no recommended numerical criteria for volatile suspended solids. Volatile
suspended solids ranged from below minimum detection limits to 4.7 mg/L (CAFH02,
November 2003) (Appendix A). No samples were collected/analyzed at CAFH01,
CAFH02, CAMC and CAMD in December 1999.
Zinc
Zinc (Zn) exists as Zn 2+ at pH of 4.0 to 5.0 in freshwater. At a pH of 7.5, zinc exists as
ZnOH + and Zn 2+ . In short-term exposures salmonids are more sensitive to zinc compared
to other families of fish, but have similar sensitivity over long-term exposures. A direct
mechanism for death due to exposure to lethal concentrations of zinc is hypoxia. Gill
tissue is damaged to such an extent by zinc that oxygen uptake is inhibited. Increased
spontaneous activity, likely due to skin or tissue irritation, was reported from trout
exposed to zinc concentrations of 100-5000 µg/L. Zinc has been shown to cause damage
to olfactory and lateral line organs. Water exposure to zinc results in accumulation of the
20

metal in skin and bone, while dietary exposure results in accumulation in gill, liver and
spleen tissues (Heath 1995).
Zinc concentrations exceeded the recommended numerical limits in Table 1 in 15
samples (Appendix A).
CONCLUSIONS
The water quality component of the WQRMP provided a 55-month evaluation of
numerous constituents of the Mokelumne River below Pardee Reservoir. Numerical
limits exist for aluminum, cadmium, chromium, copper, iron, lead, mercury, nickel,
thallium, zinc, ammonia, dissolved oxygen and pH. Samples of these constituents
resulted in instances of copper, zinc, dissolved oxygen and pH measurements that
exceeded the recommended numerical limits for the protection of freshwater aquatic life.
Camanche Reservoir is located below Penn Mine, which was historically mined for
copper and zinc from the mid-1800s intermittently through 1952. Penn Mine lies within
a deposit of the Foothill copper-zinc belt, a group of massive sulfide deposits that extend
about 250 miles along the western Sierra Nevada with numerous surface exposures;
therefore, background levels of copper and zinc can be expected to be high in this area
(E.V.S. Consultants 1989). Remediation of the Penn Mine site by EBMUD and the
California Central Valley Regional Water Quality Control Board, completed in 1999,
should result in improved water quality in the Mokelumne River. It is recommended that
monthly monitoring of copper, zinc, total hardness (to calculate numerical recommended
limits for copper and zinc) dissolved oxygen and pH be continued in the lower
Mokelumne River immediately below Camanche Dam.
Chorophyll a concentrations ranged from 0.31µg/L (CAMC, July 2000) to 19µg/L
(CAMC, December 2001); chlorophyll a (corrected) concentrations ranged from –1.2
µg/L (MS ELLIOTT, October 2000) to 14 µg/L (CAMC, December 2001). Unless
specific studies are developed to examine chlorophyll production in the lower
Mokelumne River, it is recommended that measures of chlorophyll be discontinued.
21

Measures of conductivity were significantly lower (maximum of 0.055 µmhos/cm) than
the most stringent Basin Plan (CRWQCB 1998) requirements (0.54 µmhos/cm at the
South Fork Mokelumne River at Terminous). It is recommended that conductivity
measures be discontinued.
Concentrations of nitrates, nitrites and phosphorous have well below levels that would
impact fish or other aquatic organisms. Unless specific studies are developed to examine
nutrient cycling in the lower Mokelumne River, it is recommended that measures of
nitrates, nitrites and phosphorous be discontinued.
Water temperatures are critical to various life stages of aquatic organisms in the lower
Mokelumne River and an important component of reservoir operation. It is
recommended that water temperatures continue to be monitored daily at existing
locations in Camanche Reservoir and in the lower Mokelumne River downstream of
Camanche Dam.
Measures of turbidity (turbidity, total suspended solids and volatile suspended solids)
were well below levels that impact fish and other aquatic organisms. It is recommended
that these turbidity measures be discontinued.
Two important criteria for conducting ecological analysis of zooplankton and
phytoplankton samples include sampling scale and taxonomic identification. Scale is of
extreme importance in the study of plankton ecology. Different aspects of phytoplankton
ecology occur at different scales of time and space. Nutrient regeneration and grazing of
phytoplankton can take place at scales of seconds to minutes over distances of
millimeters. Growth rates operate at scales of hours to days. Phytoplankton patches
develop at scales of weeks and kilometers. The phenomenon of missing important events
by sampling at an inappropriate scale is called aliasing. Because of the short scales at
which many events involving phytoplankton occurs, aliasing is a persistent problem in
conducting ecological analysis of plankton populations. The use of monthly grab
samples of the water column at three sample locations (CAMC, CAMD and Elliott Road
22

Bridge) results in aliasing. Assuming no losses, if an alga started at a density of one per
liter with a reproductive rate of two doublings per day, it would reach a density of 16,384
per liter in one week. In addition, grab and composite sampling of the water column
typically undersamples epilithic, epidenric, epipelic, epiphytic, epipsammic and epizoic
phytoplankton.
Correct identification of algal species may be essential for their successful use in
understanding the ecology of aquatic ecosystems (Graham and Wilcox 2000). Stoermer
(1978) emphasized that generic designations alone are not sufficiently precise for use of
diatom assemblages as indicators of environmental conditions and change. Identification
of plankton to species is a formidable task. Identification of many algae and related
protists require proficiency in the use of dissecting and compound microscopes and, in
many cases, scanning or transmission electron microscopy. Distinguishing yellow-green
algae from structurally similar but unrelated forms requires pigment analysis by
chromatography and/or examination of cells by electron microscopy. In a number of
cases algae must be cultured to elicit expression of a particular taxonomic character.
Samples collected in Camanche Reservoir and the lower Mokelumne River have only
been identified to genera and in some cases only to phylum or subphylum. Unless
specific studies are developed to examine the phyto and zooplankton communities in the
lower Mokelumne River, it is recommended that measures of these constituents be
discontinued.
