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.
-------
Hi
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. Panguitch Lake is eutrophic. It
ranked twenty-fifth in overall trophic quality when the 27 Utah
lakes and reservoirs sampled in 1975 were compared using a
combination of six parameters*. Twenty-three of the water bodies
had less median total phosphorus, 20 had less median dissolved
orthophosphorus, none had less but ten had the same median in-
organic nitrogen, 25 had less mean chlorophyll a^, and 13 had
greater mean Secchi disc transparency. Marked depression of
dissolved oxygen with depth occurred at sampling station 1 in
August (C.8 mg/1 at 7.6 meters).
Survey limnologists noted algal blooms in the lake each
sampling time and observed extensive beds of submerged macrophytes
in August.
B. Rate-Limiting Nutrient:
The algal assay results indicate the lake was nitrogen
limited in August. The lake data indicate nitrogen limitation
both sampling times.
See Appendix A.

C. Nutrient Controllability:
1. Point sources—No known wastewater treatment plants impacted
the lake during the sampling year. Lakeshore septic tanks contributed
an estimated 1.1%'of the total phosphorus load, but a shoreline survey
is needed to determine the significance of those sources.
The estimated phosphorus loading of 0.36 g/m2/year is a little
more than that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 11).
2. Non-point sources--Non-point sources contributed nearly 99%
of the phosphorus loading to the lake during the sampling year. Blue
Spring Creek contributed 46.6% of the total load, Ipson Creek
contributed 35.5%, Clear Creek added 8.0%, and the ungaged minor
tributaries and immediate drainage contributed an estimated 4.1%.

III. WATER QUALITY SUMMARY
Panguitch 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 two or more
depths at two 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 enumera-
tion; and during the first 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 a_ analysis.
The maximum depths sampled were 10.4 meters at station 1 and 1.8 meters at
station 2.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

Panguitc'n Lake was high at. the time the assay sample was
collected (08/13/75). A1so9 the significant increase in
yield with the addition of nitrogen alone indicates that
the lake was limited by nitrogen at that time.
The lake dats also indicate nitrogen limitation; i.e.,
the mear? inorganic nitrogen/orthophcsphorus ratios were 10/1
or less both sampling times.

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 (page 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 calcu-
lated 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 concentrations in Clear Creek at
station D-l and the mean annual ZZ flow.
No known wastewater treatment plants impacted the lake during the
sampl ing 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/m2/yr 0.36 0.09 5.2 0.6
Vollenweider phosphorus loadings
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Panguitch Lake:
"Dangerous" (eutrophic loading) 0.34
"Permissible" (oligotrophic loading) 0.17
