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 Moon Lake is oligotrophic. It ranked
third in overall trophic quality when the 27 Utah 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 or dissolved orthophosphorus, none had less but ten had
the same median inorganic nitrogen, six had less mean chlorophyll a_,
and seven had greater mean Secchi disc transparency. No signifi-
cant depression of dissolved oxygen occurred at depths as great as
40.2 meters.
B. Rate-Limiting Nutrient:
The algal assay results indicate the lake was phosphorus limited
in September. The lake data indicate phosphorus limitation at all
sampling stations and times.
C. Nutrient Controllability:
1. Point sources—No known point sources impacted Moon Lake
during the sampling year.
2. Non-point sources--Non-point sources contributed the entire
phosphorus loading to the lake during the sampling year. The Lake
Fork River contributed about 76% of the total load, and Brown Duck
Creek contributed about 13%.
* See Appendix A.
-------
2
The estimated phosphorus loading of 0.52 g/m2/yr is less
than that proposed by Vollenweider (Vollenweider and Dillon,
1974) as an oligotrophic loading (see page 11). Management of
the lake should be directed toward prevention of any increase
in the existing loading.

III. WATER QUALITY SUMMARY
Moon Lake was sampled twice 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 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 the last visit, 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 ^analysis. The maximum depths sampled were 11.6
meters at station 1 and 40.2 meters at station 2.
The sampling results are presented in full in Appendix D and
are summarized in the following table.

of Moon Lake was low at the time the sample was collected
(09/23/75). Also, the significant increase in yield with
the addition of phosphorus alone indicates that the lake was
limited by phosphorus at that time.
The lake data also indicate phosphorus limitation; i.e.,
the mean inorganic nitrogen/orthophosphorus ratios were 23/1
or greater, and phosphorus 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 when possible from
each of the tributary sites indicated on the map (Pa9e v). 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 Fish Creek at station B-l and the mean annual ZZ flow.
No known wastewater treatment plants impacted Moon Lake 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 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/mVyr 0.52 <0.01 46.6 25.6
Vollenweider phosphorus loadings
(g/m2/yr) based on mean depth and mean
