FOREWORD
The National Eutrophication Survey was initiated in 1972 in
response to an Administration commitment to investigate ti-.e 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>t>)],
and water quality monitoring [§106 and §305(b)] activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.
-------
iii
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 uses nutrient export, and trophi"
conditions 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 & Developments 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 and reports (McKnight, 1971; Miller, 1972)
indicate that Fremont Lake is oligotrophic. It ranked second
in overall trophic quality when the 14 Wyoming lakes and reser-
voirs sampled in 1975 were compared using a combination of six
parameters*. None of the other water bodies had less median
total phosphorus, none had less and four had the same median
inorganic nitrogen, none had less and one had the same median
dissolved orthophosphorus, two had less mean chlorophyll a^,
and none of the others had a greater mean Secchi disc trans-
parency. No depression of dissolved oxygen occurred at depths
as great as 51.8 meters.
B. Rate-Limiting Nutrient:
Because of significant nutrient changes in the samples dur-
ing shipment from the field to the laboratory, the algal assay
results are not considered representative of conditions in the
lake at the times the samples were taken (08/28/75 and 10/17/75).
The lake data indicate phosphorus limitation both sampling
times.
C. Nutrient Controllability:
1. Point sources—No known municipal or industrial waste-
water treatment plants impacted Fremont Lake during the sampling

year. Septic tanks serving lakeshore dwellings and recreational
areas were estimated to have contributed 0.6% of the total phos-
phorus load to the lake during the sampling year, but a shore-
line survey would be needed to determine the significance of
those sources.
The present phosphorus loading of 0.12 g/m2/yr is less than
that proposed by Vollenweider (Vollenweider and Dillon, 1974)
as an oligotrophic loading (see page 11), and every effort should
be made to prevent any increase in phosphorus inputs to preserve
the existing trophic Quality of Fremont Lake.
2. Non-point sources—The phosphorus contributions of non-
point sources, including direct precipitation, accounted for
99.4% of the total phosphorus load to the lake during the samp-
ling year. Pine Creek added 61.0% of the total load, and the
ungaged tributaries contributed an estimated 23.3%.
The phosphorus export rate of Pine Creek was 7 kg/km2/yr
(see page 10). This rate was somewhat lower than that of an
unimpacted tributary of nearby Boulder Lake (12 kg/km2/yr)*.

III. WATER QUALITY SUMMARY
Fremont Lake was sampled two 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 num-
ber of depths at three stations on the lake (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 both visits, a single 18.9-liter depth-inte-
grated sample was composited for algal assays. Also each time, a depth-
integrated sample was collected from each of the stations for chloro-
phyll a_ analysis. The maximum depths sampled were 51.8 meters at
stations 1 and 2 and 30.5 meters at station 3.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

Limiting Nutrient Studies:
Because of significant nutrient changes in the samples during
shipment from the field to the laboratory, the algal assay re-
sults are not considered representative of conditions in Fremont
Lake at the times the samples were taken (08/28/75 and 10/17/75).
-------

The lake data indicate phosphorus limitation both sampling
times. The mean inorganic nitrogen to orthophosphorus ratios
were 22 to 1 in August and 20 to 1 in October, and phosphorus
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 tri-
butary sites indicated on the map (page v), except for the high runoff
month of July when two samples were collected from the inlet tributary
sites. 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 tri-
butary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were deter-
mined by using a modification of a U.S. Geological Survey computer pro-
gram for calculating stream loadings*. Nutrient loads for unsampled
"minor tributaries and immediate drainage" ("II" of U.S.G.S.) were esti-
mated using the nutrient loads at station A-2, in kg/km2/year, and multi-
plying by the II area in km2.
No known wastewater treatment plants impacted Fremont Lake during the
sampling year.

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" leading 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.
Total Phosphorus Total Nitrogen
Total Accumulated Total Accumulated
grams/m2/yr 0.12 0.02 11.1 9.7
Vollenweider phosphorus loadings
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Fremont Lake:
"Dangerous" (eutrophic loading) 0.60
"Permissible" (oligotrophic loading) 0.30
