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.
-------
ili
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, muHivariate 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 Piute Reservoir is eutrophic. It
ranked twenty-third in overall trophic quality when the 27 Utah
lakes and reservoirs sampled in 1975 were compared using a com-
bination of six parameters*. Eighteen of the waterbodies had less
and one had the same median total phosphorus, 18 had less median
inorganic nitrogen, 14 had less and one had the same median dissolved
orthophosphorus, 22 had less mean chlorophyll a^, and 24 had greater
mean Secchi disc transparency. Some depression of dissolved oxygen
with depth occurred at sampling station 2 in August (3.4 mg/1 at
6.4 meters), and the near-surface concentration at station 1
in September was only 67% of saturation.
Survey limnologists did not: report surface concentrations
of algae or rooted aquatic plants in the reservoir. However,
the rather high chlorophyll a^ concentrations and numbers of phyto-
plankton at all sampling stations and times are indicative of
bloom or near-bloom conditions (see page 6).
B. Rate Limiting Nutrient:
The results of the algal assay indicate phosphorus limi-
tation in May.
The reservoir data indicate phosphorus limitation in May and
August and nitrogen limitation in September.
* See Appendix A.

C. Nutrient Controllability:
1. Point sources—No known wastewater treatment plants
impacted Piute Reservoir during the sampling year.
The present phosphorus loading of 2.03 g/m2/yr is nearly
three times that proposed by Vollenweider (Vollenwelder and Dil-
lon, 1974) as a eutrophic loading (see page 11).
2. Non-point sources—Non-point sources, including direct
precipitation, contributed all of the total phosphorus load dur-
ing the sampling year. The Sevier River added 76.0% of the total
load; the East Fork Sevier River, 20.0%; West Canal, 0.3%; and
the ungaged tributaries contributed an estimated 2.8%.
The phosphorus export rates of the Sevier River and the East
Fork Sevier River were relatively low (5 and 1 kg/km2/yr, respec-
tively; see page 10).

III. WATER QUALITY SUMMARY
Piute 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 two
or more depths at three stations in May and August and two stations in
September (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 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 ji analysis. The maximum depths
sampled were 7.6 meters at station 1, 9.8 meters at station 2, and 2.7
meters at station 3.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum, indicates that the potential primary productivity
of Piute Reservoir was moderately low when the sample was
taken (05/09/75). Also, the lack of increase in yield with
the addition of nitrogen alone and the significant increase
in yield when only phosphorus was added indicate phosphorus
limitation at that time.
The reservoir data indicate phosphorus limitation in
May and August and nitrogen limitation in September. The
mean inorganic nitrogen to orthophosphorus ratios were
36 to 1 in May, 14 to 1 in August, and 7 to 1 in September.

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), except for the high runoff month
of May when two samples were collected at three of the sites. 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 deter-
mined by using the mean annual nutrient concentrations and the mean
annual flows. Nutrient loads for unsampled "minor tributaries and
inmediate drainage" ("II" of U.S.G.S.) were estimated using the means
of the nutrient concentrations at stations A-2 and C-l and multiplying
the means by the ZZ mean annual flow.
No known municipal wastewater treatment plants impacted Piute Reser-
voir 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.
Total Phosphorus Total Nitrogen
Total Accumulated Total Accumulated
grams/mVyr 2.03 0.97 27.0 6.8
Vollenweider phosphorus loadings
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Piute Reservoir:
"Dangerous" (eutrophic loading) 0.76
"Permissible" (oligotrophic loading) 0.38
