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.
-------
111
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
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 and Development, U.S. Environmental Protection Agency)
expresses sincere appreciation to the Utah Department of Social
Services and the Utah Department of Natural Resources for pro-
fessional involvement, to the Utah National Guard for conducting
the tributary sampling phase of the Survey, and to those Utah
wastewater treatment plant operators who voluntarily provided
effluent samples and flow data.
The staffs of the Bureau of Water Quality of the Division
of Health and the Division of Wildlife Resources provided inval-
uable lake documentation and counsel during the Survey, reviewed
the preliminary reports, and provided critiques most useful in
the preparation of this Working Paper series.
Major General Maurice L. Watts, the Adjutant General of Utah,
and Project Officer Lt. Colonel T. Ray Kingston, who directed, the
volunteer efforts of the Utah National Guardsmen, are also grate-
fully acknowledged for their assistance to the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that the main body of Fish Lake is
mesotrophic but shallow Widgeon Bay is eutrophic (station 3;
see map, page v). This lake ranked ninth in overall trophic
quality when the 27 Utah lakes and reservoirs sampled in 1975
were compared using a combination of six parameters* (however,
if the very high Widgeon Bay August chlorophyll £ value of 55.6
ug/1 is omitted, Fish Lake would rank fifth).
Ten of the water bodies had less median total phosphorus, none
had less and ten had the same median inorganic nitrogen, five
had less and two had the same median orthophosphorus, 20 had
less mean chlorophyll a^ (eight omitting the 55.6 value), and none
had greater mean Secchi disc transparency. No significant reduction
of dissolved oxygen with depth occurred at any sampling station or
time.
Survey limnologists did not observe surface concentrations of
algae but noted sparse macrophytes in Widgeon Bay at station 3.
B. Rate-Limiting Nutrient:
Due to significant changes in nutrients in the samples during
shipment to the laboratory, the algal assay results are not con-
sidered representative of conditions in the lake at the times
the samples were collected. The lake data indicate nitrogen limi-
tation both sampling times.
* See Appendix A.

C. Nutrient Controllability:
1. Point sources—No known municipal or industrial wastewater
treatment plants impacted Fish Lake during the sampling year. Septic
tanks serving lakeshore dwellings and recreational facilities
contributed an estimated 8.1% of the total phosphorus load, but
a shoreline survey is needed to determine the significance of
those sources.
The present phosphorus loading of 0.05 g/m2/year is less
than that proposed by Vollenweider (Vollenweider and Dillon, 1974)
as an oligotrophic loading Csee page 11). Because of the very long
hydraulic retention time (58.5 years), phosphorus inputs should be
minimized as much as possible to preserve the existing trophic
quality of the main body of Fish Lake.
2. Non-point sources—Non-point sources, including direct
precipitation, added 91.9% of the total phosphorus load to the lake
during the sampling year. Jorgenson Creek contributed 24.2% of
the total; Bowery Creek, 7.1%, Twin Creek, 3.0%; Doctor Creek, 2.0%;
and the ungaged tributaries, an estimated 20.2%.
The phosphorus export rates of Oorgenson Creek, Bowery
Creek, Twin Creek, and Doctor Creek were 14, 13, 12, and 1 kg/km2/
year, respectively (see page 10).

III. WATER QUALITY SUMMARY
Fish 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
one or more depths at three stations on the lake (see map, page v).
During each visit, a single depth-Integrated (4.6 m or near bottom
to surface) sample was composited from the stations for phytoplankton
identification and enumeration; and during both 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
29.9 meters at station 1, 30.8 meters at station 2, and near-surface
only at station 3.
The sampling results are presented in full in Appendix D and
are summarized in the following table.

Limiting Nutrient Study:
The algal assay results are not considered representative
of conditions in the lake because of significant changes in the
sample nutrients from the time of collection to the time the assays
were begun.
-------

The lake data indicate nitrogen limitation both sampling
times. The mean inorganic nitrogen to orthophosphorus ratios
were 8 to 1 in August and in September, and nitrogen limitation
would be expected.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Utah National
Guard collected monthly near-surface grab samples from each of the
tributary sites indicated on the map (page v) when the sites were
accessible. Sampling was begun in November, 1974, and was completed
in October, 1975.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Utah District Office of the U.S. Geological Survey for the
tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were
calculated using mean annual concentrations and mean annual flows.
Nutrient loads for unsampled "minor tributaries and immediate
drainage" ("ZZ" of U.S.G.S.) were estimated using the mean concen-
trations in Twin Creek at station D-l and the mean annual ZZ flow.
No known wastewater treatment plants impacted Fish 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" 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.
