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.

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.

STARVATION RESERVOIR
STORET NO. 4921
CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Starvation Reservoir is rneso-
trophic. It ranked tenth in overall trophic quality when
the 27 Utah lakes and reservoirs sampled in 1975 were com-
pared using a combination of six parameters*. Seven of the
water bodies had less and one had the same median total phos-
phorus, none had less and ten had the same median inorganic
nitrogen, five had less and two had the same median dissolved
orthophosphorus, ten had less chlorophyll a_, and nine had
greater mean Secchi disc transparency. Significant depression
of dissolved oxygen with depth occurred at sampling station 1
in August and September and at stations 2 and 4 in August.
Survey limnologists did not observe surface concen-
trations of algae or aquatic macrophytes in the reservoir.
B. Rate Limiting Nutrient:
The results of the algal assay are not considered re-
presentative of conditions in the reservoir because of significant
changes in nutrients in the samples from the time of col-
lection to the beginning of the assays.
The reservoir data indicate nitrogen limitation all three
sampling times.
* See Appendix A.
-------
C. Nutrient Controllability:
1. Point sources—No known wastewater treatment plants
impacted Starvation Reservoir during the sampling year.
The sampling year phosphorus loading of 2.70 g/m2 is four
times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 11). During the
sampling year. Starvation Reservoir was still filling and, at
that time, apparently had not responded to the high loading.
However, it is probable the trophic quality of the reservoir
will deteriorate if the load measured during the sampling year
is not reduced.
2. Non-point sources—Non-point sources, including direct
precipitation, contributed all of the total phosphorus load
to the reservoir during the sampling year. The Strawberry
River added 82.5% of the total; the Duchesne River diversion,
5.3%; and the ungaged tributaries contributed an estimated
11.6%.
The phosphorus export rate of the Strawberry River was
10 kg/km2 during the sampling year (see page 10).

III. WATER QUALITY SUMMARY
Starvation 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 a number of depths at four stations on the reservoir (see map,
page v). During each visit, a single depth-Integrated (4.6 m to sur-
face) sample was composited from the stations for phytoplankton identi-
fication and enumeration; and during the first and last 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 18.3 meters at station 1, 22.9 meters at station 2,
5.8 meters at station 3, and 14.0 meters at station 4.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

C. Limiting Nutrient Study:
The results of the el gal assay are not considered repre-
sentative of reservoir conditions because significant nutrient
changes occurred in the samples from the time of collection
to the beginning of the assays.
The reservoir data indicate nitrogen limitation; i.e.,
the mean inorganic nitrogen to orthophosphorus ratios were
8 to 1 in May, 13 to 1 in Augusts and 8 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 months
of May and June when two samples were collected. Sampling was begun
in November, 1974, and was completed in September, 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 tri-
butary sites nearest the reservoir.
In this report, nutrient loads for sampled tributaries were deter-
mined by using a modification of a U.S. Geological Survey computer
program for calculating stream loadings*. Nutrient loads for un-
sampled "minor tributaries and immediate drainage" ("ZZ" of U.S.G.S.)
were estimated using the nutrient loads, in kg/km2/year, at station
A-2 and multiplying by the ZZ area in km2.
No known wastewater treatment plants impacted Starvation Reservoir
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/m2/yr 2.70 2.45 34.0 26.2
Vollenweider phosphorus loadings
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Starvation Reservoir:
