FOREWORD
The National Eutrophication Survey was initiated in 1972 in
response to an Administration commitment to investigate the nation-
wide threat of accelerated eutrophication to freshwater lakes and
reservoirs.
OBJECTIVES
The Survey was designed to develop, in conjunction with state
environmental agencies, information on nutrient sources, concentrations,
and impact on selected freshwater lakes as a basis for formulating
comprehensive and coordinated national, regional, and state management
practices relating to point-source discharge reduction and non-point
source pollution abatement in lake watersheds.
ANALYTIC APPROACH
The mathematical and statistical procedures selected for the
Survey's eutrophication analysis are based on related concepts that:
a. A generalized representation or model relating
sources, concentrations, and impacts can be constructed.
b. By applying measurements of relevant parameters
associated with lake degradation, the generalized model
can be transformed into an operational representation of
a lake, its drainage basin, and related nutrients.
c. With such a transformation, an assessment of the
potential for eutrophication control can be made.
LAKE ANALYSIS
v
In this report, the first stage of evaluation of lake and water-
shed data collected from the study lake and its drainage basin is
documented. The report is formatted to provide state environmental
agencies with specific information for basin planning [§303(e)], water
quality criteria/standards review [§303(c)], clean lakes [§314(a,b)],
and water quality monitoring [§106 and §305(b)] activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.
-------
Beyond the single lake analysis, broader based correlations
between nutrient concentration (and loading) and trophic condi-
tion are being made to advance the rationale and data base for
refinement of nutrient water quality criteria for the Nation's
fresh water lakes. Likewise, multivariate evaluations for the
relationships between land use, nutrient export, and trophic
condition, by lake class or use, are being developed to assist
in the formulation of planning guidelines and policies by EPA
and to augment plans implementation by the states.
ACKNOWLEDGEMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U.S. Environmental Protection Agency)
expresses sincere appreciation to the California State Water
Resources Control Board and the nine Regional Water Quality
Control Boards for professional involvement, to the California
National Guard for conducting the tributary sampling phase of
the Survey, and to those California wastewater treatment plant
operators who voluntarily provided effluent samples and flow
data.
The staff of the Division of Planning and Research of the
State Water Resources Control Board provided invaluable lake
documentation and counsel during the Survey, coordinated the
reviews of the preliminary reports, and provided critiques
most useful in the preparation of this Working Paper series.
Major General Glen C. Ames, the Adjutant General of Cali-
fornia, and Project Officer Second Lieutenant Terry L. Barrie,
who directed the volunteer efforts of the California National
Guardsmen, are also gratefully acknowledged for their assistance
to the Survey.

I. CONCLUSIONS
A. Trophic Condition*:
Survey data indicate that Don Pedro Reservoir is meso-
trophic. It ranked eighth in overall trophic quality among
the 24 California lakes and reservoirs sampled in 1975 when
compared using a combination of six water quality parameters**.
Four of the water bodies had less median total phosphorus,
four had less and two had the same median dissolved orthophos-
phorus, nine had less and five had the same median inorganic
nitrogen, nine had less mean chlorophyll a^ and ten had greater
mean Secchi disc transparency. Some depression of dissolved
oxygen with depth occurred at stations 1, 2, and 3 in November.
Survey limnologists noted small amounts of macrophytes in
the shallows in June. Others also have assessed Don Pedro
Reservoir as mesotrophic with no apparent nuisance conditions
(Johns, 1975).
B. Rate-Limiting Nutrient:
The algal assay results are not considered representative
of conditions in the reservoir at the times the samples were
collected.
The reservoir data indicate nitrogen limitation in March
and phosphorus limitation in June and November.
* Trophic assessment is based on levels of nutrients, dissolved oxygen, and
chlorophyll a; phytoplankton kinds and numbers; and transparency (Allurn
et al., 1977T.
** See Appendix A.
-------
C. Nutrient Controllability:
1. Point sources—It is estimated that the four known
wastewater treatment plants contributed a little over 19% of the
total phosphorus load to the reservoir during the sampling
year. The Sonora plant accounted for 11.3% of the total,
and the other three plants collectively contributed 8.0%.
The estimated phosphorus loading of 1.05 g/m2/yr is a
little more than that proposed by Vollenweider (Vollenweider
and Dillon, 1974) as a eutrophic loading (see page 13). It
appears that 85% phosphorus removal at the four wastewater
treatment plants would reduce the overall loading to 0.88
g/m2/yr (a mesotrophic loading). However, the point-source
proportion of the total phosphorus load may be less than is
shown since several of the significant tributaries of the
reservoir were not gaged, and background phosphorus loads for
those streams had to be estimated (see below). Therefore, the
limitation of this assessment of point-source phosphorus con-
trol should be recognized.
2. Non-point sources—It is estimated that non-point sources,
including direct precipitation, accounted for almost 81%
of the total phosphorus load during the sampling year. The
actual non-point contribution may be greater than that, however,
since the North Fork Tuolumne River and Sullivan, Turnback, and
Woods creeks were not gaged; and the drainage areas and flows of
these streams were included in the estimated drainage area and
flow of the "minor tributaries and immediate drainage" ("II" of
-------
U.S.G.S.). The phosphorus load attributed to ZZ was esti-
mated using the mean ZZ flow and the mean phosphorus concen-
tration in Moccasin Creek (0.040 mg/1) which was assumed to
be a typical non-point concentration.

III. WATER QUALITY SUMMARY
Don Pedro Reservoir was sampled three times during the open-water
season of 1975 by means of a pontoon-equipped Huey helicopter. Each
time, samples for physical and chemical parameters were collected from
one or more depths at five stations on the reservoir (see map, page v).
During each visit, a single depth-integrated (4.6 m to surface) sample
was composited from the stations for phytoplankton identification and
enumeration; and during the first and last visits, a single 18.9-liter
depth-integrated sample was collected from each of the stations for
chlorophyll a_ analysis. The maximum depths sampled were 54.9 meters
at stations 1, 2, and 3; 73.2 meters at station 4; and 32.0 meters at
station 5.
The sampling results are presented in full in Appendix D and are

C. Limiting Nutrient Study:
Due to significant nutrient changes in the samples
during shipment from the field to the laboratory, the algal
assay results are not considered representative of conditions
in the reservoir at the times of sampling (03/11/75 and 11/12/75),
The reservoir data indicate nitrogen limitation in March
and phosphorus limitation in June and November (the mean in-
organic nitrogen/orthophosphorus ratios were 11/1, 15/1, and
21/1, respectively).
-------
IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the California National
Guard collected monthly near-surface grab samples from each of the
tributary sites indicated on the map (page v), except for the high
runoff months of April and May when two samples were collected. Sam-
pling was begun in November, 1974, and was completed in August, 1975.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the California District Office of the U.S. Geological Survey for the
tributary sites nearest the reservoir.
In this report, nutrient loads for sampled tributaries were cal-
culated using mean annual concentrations and mean annual flows. Nu-
trient loads shown are those measured minus point-source loads, if any.
Nutrient loads for unsampled "minor tributaries and immediate
drainage" ("ZZ" of U.S.G.S.) were estimated using the mean concentrations
in Moccasin Creek at station D-l and the mean annual ZZ flow.
The operators of the Tuolumne Co. W.D. #1, Jamestown, Sonora, and
Tuolumne wastewater treatment plants provided monthly effluent samples
and corresponding flow data.

F. Yearly Loads:
In the following table, the existing phosphorus loadings
are compared to those proposed by Vollenweider (Vollenweider
and Dillon, 1974). Essentially, his "dangerous" loading is
one at which the receiving water would become eutrophic or
remain eutrophic; his "permissible" loading is that which
would result in the receiving water remaining oligotrophic
or becoming oligotrophic if morphometry permitted. A meso-
trophic loading would be considered one between "dangerous"
and "permissible".
Note that Vollenweider's model may not be applicable to
water bodies with short hydraulic retention times.
