FOREWORD
The National Eutrophicatlon 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, 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
flanninq [§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 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 cf
planning guidelines and policies by the U.S. Environmental Protection
Agency and to augment plans implementation by the states.

REPORT ON FORT COBB RESERVOIR, OKLAHOMA
STORET NO. 4005
I. CONCLUSIONS
A. Trophic Condition:*
Survey data indicate that Fort Cobb Reservoir is eutrophic,
i.e., nutrient rich and highly productive. Whether such nutrient
enrichment is to be considered beneficial or deleterious is
determined by its actual or potential impact upon designated
beneficial water uses of each lake.
Chlorophyll a^ values in the lake ranged from 3.3 ug/1 in
April to 40.9 ug/1 in August, with a mean of 15.0 ug/1. High
productivity was particularly manifest in the area of the Cobb
Creek—Spring Creek inflows (mean chlorophyll a^ of 29.0 ug/1).
Potential for primary production as measured by algal assay
control yield was low in the spring sampling period and high
during the autumn. Of the 16 Oklahoma lakes sampled in 1974,
11 had higher median total phosphorus levels, 11 had higher
median inorganic nitrogen values, and 10 had higher median
orthophosphorus levels than Fort Cobb Reservoir.
Survey limnologists reported floating clumps of algae
during the spring at Station 01, but no problem aquatic macro-
phytes.
*See Appendix E.
-------
B. Rate-Limiting Nutrient:
The algal assay results suggest phosphorus limitation in
Fort Cobb Reservoir during the spring sampling and nitrogen
limitation in the fall. The lake data indicate nitrogen limi-
tation at all sampling times.
C. Nutrient Controllability:
1. Point sources -
Only one known point source, the town of Eakly, was
known to impact Fort Cobb Reservoir during the sampling year.
This source was estimated to contribute 2.8% of the total
phosphorus load to the lake.
The present calculated phosphorus loading of 0.57
g P/m^/yr is over three times that proposed by Vollenweider
(1975) as a "eutrophic" loading. If the present loading
continues, increasingly undesirable responses to enrichment
are likely to occur.
2. Nonpoint sources -
The phosphorus contributions of nonpoint sources,
including precipitation, accounted for 97.2% of the total
phosphorus load during the sampling year. Cobb Creek contri-
buted 42.9%, Spring Creek contributed 14.5%, and Willow Creek
contributed 6.3%. The ungaged minor tributaries and immediate
-------
drainage contributed an estimated 30.4% of the total
phosphorus load.
The nutrient export rates of the gaged tributaries
(range of 8-14 kg P/krcr/.yr, mean of 11 kg P/km^/yr) are
slightly higher but comparable to the tributary rates of
2
nearby Elsworth Lake* (range of 3-8 kg P/km /yr, mean of
6 kg P/km2/yr).
*See Working Paper No. 583, "Report on Elsworth Lake".

II. LAKE AND DRAINAGE BASIN CHARACTERISTICS
Lake and drainage basin characteristics are itemized below.
Lake morphometry 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 out-
let. 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.
A. Lake Morphometry:
1. Surface area: 16.47 krrr.
2. Mean depth: 6.4 meters.
3. Maximum depth: 19.2 meters.
4. Volume: 105.408 x 106 m3.

III. LAKE WATER QUALITY SUMMARY
Fort Gobb 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 three stations on the lake and from a number o,f
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 sampled were 15.2
meters at Station: 01, 6.4 meters at Station 02, and 1.5 meters at
Station 03. 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 maxi-
mum 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.

Discussion -
The control yields of the assay alga, Selenastrum capri-
cornutum, indicate that potential for primary production in Fort
Cobb Reservoir was low during spring collection and high during
autumn sampling. In the spring, 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 only nitrogen resulted in a yield which
was not significantly greater than that of the control.
In the autumn assay, the addition of nitrogen alone produced
a significant increase in yield over that of the control suggest-
ing primary nitrogen limitation in the sample. The addition of
only phosphorus produced a slight increase in yield over that of
the control. However, substantial nutrient changes in the samples
prior to assay place the findings of both spring and fall assays
in question.
The lake data indicate that nitrogen was the primary limiting
nutrient during all sampling periods (the mean inorganic nitrogen
to orthophosphorus (N/P) ratios were 10/1 or less, and nitrogen
limitation would be expected).
-------
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), except
for the high runoff months of April and May when two samples 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 tribu-
tary 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 tribu-
taries are those measured minus known point source loads, if any.
Nutrient loadings for unsampled "minor tributaries and immedi-
ate drainage" ("ZZ" of USGS) were estimated by using the mean
annual nutrient loads, in kg/km2/year, in Cobb Creek and Willow
Creek at Stations A-2 and C-l and multiplying the means by the ZZ
2
area in km .
Nutrient loads for the Eakly wastewater treatment plant were
estimated at 1.134 kg P and 3.401 kg N/capita/year.

E. 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 be applicable to water
bodies with very short retention times or in which light penetration
is severely restricted from high concentrations of suspended solids
in the surface waters.
