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.
-------
m
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
freshwater 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.
ACKNOWLEDGMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Nebraska Department of
Environmental Control for professional involvement, to the
Nebraska National Guard for conducting the tributary sampling
phase of the Survey, and to those wastewater treatment plant
operators who voluntarily provided effluent samples and flow
data.
The staff of the Water Pollution Control Division, Department
of Environmental Control, provided invaluable 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 Francis L. Winner, the Adjutant General of Nebraska,
and Project Officer Colonel Burl M. Johnson, who directed the volun-
teer efforts of the Nebraska National Guardsmen, are also gratefully
acknowledged for their assistance to the Survey.

I. CONCLUSIONS
A. Trophic Condition
Survey data indicate Harry D. Strunk Reservoir is eutrophic.
It ranked seventh in overall trophic quality when the nine
Nebraska reservoirs sampled in 1974 were compared using a combina-
tion of six lake parameters*. Four of the reservoirs had less
median total phosphorus, one had less and one had the same
median dissolved phosphorus, seven had less median inorganic
nitrogen, two had less mean chlorophyll a_, and six had greater
mean Secchi disc transparency. Depression of dissolved
oxygen with depth occurred at both stations in July.
Survey limnologists noted an algal bloom along the north
shore near sampling station 2 in September, and the phytoplankton
data indicate bloom conditions in April (see page 6).
B. Rate-Limiting Nutrient:
The algal assay results indicate the reservoir was limited by
phosphorus at the time the sample was collected (04/16/74). The
reservoir data indicate phosphorus limitation in April and Septem-
ber.
C. Nutrient Controllability:
1. Point sources—It is calculated that known point
sources contributed about 3% of the total phosphorus load to
* See Appendix A.

Strunk Reservoir during the sampling year. The Curtis muni-
cipal wastewater treatment plant was the major contributor.
During the sampling year, the reservoir received a total phos-
phorus loading over eleven times that proposed by Vollenweider
(Vollenweider and Dillon, 1974) as a eutrophic loading (see page
11). Therefore, it is unlikely that removal of phosphorus at
the Curtis wastewater treatment plant would result in signifi-
cant improvement in the trophic condition of the reservoir.
2. Non-point sources—It is estimated that non-point sources
contributed about 97% of the total phosphorus load to the reser-
voir during the sampling year. Medicine Creek contributed 80.5%
of the total load. Apparently, a significant reduction in the
phosphorus loading to the reservoir can be achieved only through
non-point-source control in the Medicine Creek drainage.
The phosphorus export rate of Medicine Creek was 27 kg/km2
during the sampling year (see page 10). This rate is about twice
that of Red Willow Creek, a tributary of nearby Hugh Butler Reser-
voir*, and about 13 times that of the Republican River at the inlet
of Swanson Reservoir**.

III. LAKE WATER QUALITY SUMMARY
Harry D. Strunk Reservoir was sampled three times during
the open-water season of 1974 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 reservoir (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 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 9.1 meters
at station 1 and 10.7 meters at station 2.
The sampling results are presented in full in Appendix D and
are summarized in the following table (the July nutrient samples
were not properly preserved and were not analyzed).

2. Discussion -
The control yield of the assay alga, Selenastrum ca pr i-
cornutum, indicates that the potential primary productivity
of Harry D. Strunk Reservoir was low at the time the assay
sample was collected (04/16/74). Also a significant increase
in yield with the addition of phosphorus alone indicates
that the reservoir was limited by phosphorus at that time.
Note that the addition of nitrogen alone resulted in a
yield no greater than that of the control.
The reservoir data further indicate phosphorus limitation;
i. e., the mean inorganic nitrogen/orthophosphorus ratios at
both stations were 15/1 or greater in April and September.

IV. NUTRIENT LOADINGS
See Appendix E for data)
For the determination of nutrient loadings, the Nebraska National
Guard attempted to collect monthly near-surface grab samples from
each of the tributary sites indicated on the map (page vi), except
for the high runoff month of May, when the sites were visited twice.
Sampling was begun in August, 1974, and was completed in June, 1975.
Because of insufficient flows, no samples were collected at the sam-
pling sites on Mitchell and Spring creeks during the sampling year.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Nebraska District Office of the U.S. Geological Survey for the
tributary sites nearest the reservoir.
In this report, nutrient loads for sampled tributaries were
determined by using a modification of a U.S. Geological Survey
computer program for calculating stream loadings*. Nutrient loads
shown are those measured minus point-source loads, if any.
Nutrient loads for unsampled "minor tributaries and immediate
drainage" ("ZZ" of U.S.G.S.) were estimated using the means of the
nutrient loads, in kg/km2/year, at station A-2 and multiplying the
means by the ZZ area in km2.
The operator of the Curtis wastewater treatment plant provided
an insufficient number of monthly effluent samples and corresponding
flow data; nutrient loads were estimated at 1.134 kg P and 3.401 N/
capita/year, and flows were estimated at 0.3785 m3/capita/day.
Results of analyses of the Curtis samples are included in Appendix E.

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.
