FOREWORD
The National Eutrophication Survey was Initiated 1n 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, concen-
trations, 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 nonpoint source pollution abatement in lake water-
sheds.
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
watershed 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 qualitv 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 condition
are being made to advance the rationale and data base for refine-
ment 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 the U.S. Environmental Protection
Agency and to augment plans implementation by the states.

REPORT ON ELSWORTH LAKE, OKLAHOMA
STORE! NO. 4003
I. CONCLUSIONS
A. Trophic Condition:*
Survey data indicate that Elsworth Lake is eutrophic,
i.e., nutrient rich and potentially highly productive. Whether
such nutrient enrichment is to be considered beneficial or
deleterious is determined by the actual or potential impact
upon designated beneficial water uses of the lake.
Of the 16 Oklahoma lakes (including Texoma Lake) sampled
in 1974, 12 had higher median total phosphorus levels, 13 had
higher median inorganic nitrogen values, and 13 had higher
median orthophosphorus levels than Elsworth Lake. Chlorophyll
a^ levels in the lake ranged from 1.5 yg/1 in June to 21.0 ug/1
in October, with a mean of 8.4 yg/1. Potential for primary
production as measured by algal assay control yield was low
during spring collection, and Secchi disc transparency was
poor.
Survey limnologists did not observe any problem algal
blooms or aquatic macrophytes in Elsworth Lake during the
sampling year.
*See Appendix E.
-------
B. Rate-Limiting Nutrient:
The lake data (ratios of inorganic nitrogen to orthophosphorus)
suggest primary limitation by nitrogen during the April and October
sampling periods, but phosphorus limitation during June.
C. Nutrient Controllability:
1. Point sources -
It is calculated that known point sources contributed
36.0% of the total phosphorus load to Elsworth Lake during
the sampling year. The Apache plant contributed 33.1% of
the total phosphorus load, and the Fletcher plant contri-
buted 2.9%.
During the 1974 sampling year, the lake received a
total phosphorus loading greater than that proposed by
Vollenweider (1975) as an "oligotrophic" loading but less
than his "eutrophic" loading values (Section IV-F). Al-
though Vollenweider's model may not be applicable to
highly turbid water bodies, elimination of known point
sources would reduce loading to an "oligotrophic" level
and substantially lower the potential for the occurrence
of nuisance conditions in Elsworth Lake.
-------
2. Nonpoint sources -
It is estimated that nonpoint sources, including pre-
cipitation, contributed 64.0% of the total phosphorus load
to Elsworth Lake during the sampling year. East Cache
Creek contributed 22.7% of the total load, and Chandler
Creek and Mission Creek contributed 1.6% and 4.3%, respec-
tively. Ungaged drainage areas were estimated to have con-
tributed 28.1% of the total phosphorus load.
The phosphorus export rates of the gaged tributaries
to Elsworth Lake (range of 3-8 kg P/km2/yr, mean of 6 kg
P/km2/yr) compare favorably with the tributary rates of
nearby Fort Cobb Reservoir* (range of 8-13 kg P/km2/yr,
mean of 11 kg
*See "Preliminary Report on Fort Cobb Reservoir."

II. LAKE AND DRAINAGE BASIN CHARACTERISTICS
Lake and drainage basin characteristics are itemized below.
Lake surface area and mean depth were provided by the Oklahoma
Department of Pollution Control; maximum depth was provided by
the Oklahoma Water Resources Board. Tributary flow data were
provided by the Oklahoma District Office of the U.S. Geological
Survey (USGS). Outlet drainage area includes the lake surface
area. Mean hydraulic retention time was obtained by dividing
the lake volume by mean flow of the outlet. Precipitation values
are estimated by methods as outlined in National Eutrophication
Survey (NES) Working Paper No. 175. A table of metric/English
conversions is included as Appendix A.

III. LAKE WATER QUALITY SUMMARY
Elsworth Lake 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 four stations on the lake (Stations 03 and 04
were only sampled twice) and from a number of depths at each
station (see map, page v). During each visit, depth-integrated
samples were collected from each station for chlorophyll a_
analysis and phytoplankton identification and enumeration.
During the first and last visits, 18.9-liter depth-integrated
samples were composited for algal assays. Maximum depths sam-
pled were 10.7 meters at Station 01, 6.1 meters at Station 02,
12.5 meters at Station 03, and 4.6 meters at Station 04. For
a more detailed explanation of NES methods, see NES Working
Paper No. 175.
The results obtained are presented in full in Appendix C
and are summarized in III-A for waters at the surface and at
the maximum depth for each site. Results of the phytoplankton
counts and chlorophyll a_ determinations are included in III-B.
Results of the limiting nutrient study are presented in III-C.

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum, indicates that the potential for primary produc-
tion was low in Elsworth Lake during the time of sampling.
The addition of orthophosphorus alone produced a significant
increase in yield over that of the control, indicating the
sample was phosphorus limited at that time. The addition
of nitrogen alone did not result in any increase in yield
over that of the control, while the simultaneous addition
of both nutrients produced maximum increase in yield over
the control. It should be noted that significant nutrient
losses occurred in assay samples prior to analysis; the
results should not be considered representative of growth
responses in the lake.
The autumn assay sample was broken during shipment,
so is not included in this report.
-------
11
The mean inorganic nitrogen to orthophosphorus (N/P)
ratios in the lake data were 9/1 and <4/l in the spring and
fall, respectively, suggesting primary limitation by nitro-
gen at those times. The summer N/P ratio was 14/1, sug-
gesting phosphorus limitation (a mean N/P of 14/1 or greater
generally reflects phosphorus limitation).
-------
12
IV. NUTRIENT LOADINGS
(See Appendix D for data)
For the determination of nutrient loadings, the Oklahoma
National Guard collected monthly near-surface grab samples from
each of the tributary sites indicated on the map (page v), ex-
cept for the high runoff months of April and May when two sam-
ples were collected. 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 Oklahoma District Office of the USGS for the
tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were
determined by using a modification of a USGS computer program
for calculating stream loadings. Nutrient loads indicated for
tributaries are those measured minus known point source loads,
if any.
Nutrient loadings for unsampled "minor tributaries and imme-
diate drainage" ("ZZ" of USGS) were estimated by using the mean
annual nutrient loads, in kg/knr/yr, in Chandler Creek and
Mission Creek at Stations B-l and C-l, and multiplying the means
by the ZZ area in km^.
The operators of the Fletcher and Apache wastewater treat-
ment plants provided monthly effluent samples and corresponding
flow data.

F. Yearly Loadings:
In the following table, the existing phosphorus annual
loading is compared to the relationship proposed by Vollenweider
(1975). Essentially, his "eutrophic" loading is that at which
the receiving waters would become eutrophic or remain eutrophic;
his "oligotrophic" loading is that which would result in the
receiving water remaining oligotrophic or becoming oligotrophic
if morphometry permitted. A "mesotrophic" loading would be
considered one between "eutrophic" and "oligotrophic".
Note that Vollenweider's model may not apply to lakes with
short hydraulic retention times or in which light penetration is
severely restricted by high concentrations of suspended solids
in the surface waters.
