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
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 concentrations (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
freshwater 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.
ACKNOWLEDGMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Wyoming Department of Environ-
.mental Quality for professional involvement, to the Wyoming National
Guard for conducting the tributary sampling phase of the Survey,
and to those Wyoming wastewater treatment plant operators who
voluntarily provided effluent samples.
The staff of the Water Quality Division provided invaluable
lake documentation and counsel during the Survey, reviewed the
preliminary reports, and provided critiques most useful in the
preparation of this Working Paper series.
Brigadier General James L. Spence, The Adjutant General of
Wyoming, and Project Officer Colonel Donald L. Boyer, who directed
the volunteer efforts of the Wyoming National Guardsmen, are also
gratefully acknowledged for their assistance to the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Big Sandy Reservoir is entrophi'c.
It ranked tenth in overall trophic condition when the 14 Wyoming
lakes and reservoirs sampled in 1975 were compared using a com-
bination of six parameters*. All of the other water bodies had
less median total phosphorus, 12 had less median dissolved
orthophosphorus, six had less median inorganic nitrogen, three
had less mean chlorophyll a_, and all of the others had greater
mean Secchi disc transparency. No significant depression of
dissolved oxygen with depth occurred at any of the sampling
times.
Survey limnologists observed heavy turbidity on each sampling
occasion. The Wyoming Game and Fish Commission reports that the
turbidity is due to finely divided, almost colloidal silt and
is serious enough to have depressed the brown trout population
in the reservoir (Miller, 1973).
B. Rate-Limiting Nutrient:
Due to significant changes in the sample nutrient levels,
the assay results are not considered representative of conditions
in the reservoir at the times the samples were taken.
The reservoir data indicate nitrogen limitation at all sampling
times; however because of turbidity, primary productivity probably
is light-limited much of the time.
* See Appendix A.

C. Nutrient Controllability:
1. Point sources--No known point sources impacted Big
Sandy Reservoir during the sampling year.
2. Non-point sources--The Big Sandy River coi~.tributed
71.7% of the total phosphorus load to the reservoir, and the
minor tributaries and immediate drainage contributed an esti-
mated 26.8% of the load.
The reservoir received a total phosphorus loading over twice
that proposed by Vollenweider (Vollenweider and Dillon, 1974)
as a eutrophic loading (see page 11). The apparent lack of
nuisance plant growth in the lake probably is due to light
limitation caused by turbidity.

III. WATER QUALITY SUMMARY
Big Sandy 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
a number of depths at two 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 composited for algal assays. Also each
time, a depth-integrated sample was collected from each of the stations
for chlorophyll a_ analysis. The maximum depths sampled were 13.4
meters at station 1 and 7.3 meters at station 2.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

at the times the samples were collected (05/19/75 and 10/16/75).
The reservoir data indicate nitrogen limitation at all sam-
pling times (the mean inorganic nitrogen/orthophosphorus ratios
were 4/1 or less, and nitrogen limitation would be expected).

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Wyoming 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 month of May when two samples were collected. Sampling was
begun in October, 1974, and was completed in July, 1975.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Wyoming District Office of the U.S. Geological Survey for the
tributary sites nearest the reservoir.
In this report, nutrient loads for sampled tributaries were
determined by using a modification of a U.S. Geological Survey computer
program for calculating stream loadings*. Nutrient loads for unsampled
"minor tributaries and immediate drainage" ("ZZ" of U.S.G.S.) were
estimated using the nutrient loads, in kg/km2/year, at station A-2
and multiplying by the ZZ area in km2.
No known wastewater treatment plants impacted the reservoir during
the sampling year.

E. 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 eutrcphic 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.
Total Phosphorus Total Nitrogen
Total Accumulated Total Accumulated
grams/m2/yr 1.20 0.18 16.0 4.1
Vollenweider phosphorus loadings
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Big Sandy Reservoir:
"Dangerous" (eutrophic loading) 0.54
"Permissible" (oligotrophic loading) 0.27
