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, 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 quality criteria/standards review
L§303(c)J, 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.
ACKNOWLEDGMENTS

I. CONCLUSIONS
A. Trophic Condition:*
Survey data indicate that Lake Thunderbird is eutrophic.
Chlorophyll a_ values in the lake ranged from a summertime low
of 2.7 ng/1 to a high of 13.2 yg/1 in spring, with a mean of
8.4 yg/1. Nutrient losses in the samples likely contributed
to the low apparent potential for primary productivity estimated
by algal assay control yield. Of the 16 Oklahoma lakes sampled
in 1974 (including Lake Texoma) 13 had higher median total
phosphorus levels, 9 had higher median inorganic nitrogen values,
and 12 had higher median orthophosphorus levels than Lake
Thunderbird.
Survey limnologists did not report any problem conditions
in the lake but did note that it was highly turbid. The direct
relationship between Secchi disc depth (light penetration) and
chlorophyll a_ levels, often noted in light-limited systems,
was not apparent in Lake Thunderbird. It is likely that a
significant portion of the turbidity can be attributed to
phytoplankton growth in the moderately rich lake.
*See Appendix E.
-------
B. Rate-Limiting Nutrient:
The algal assay results indicate that Lake Thunderbird was
limited by available phosphorus at the times of sampling. The
lake data, however, suggest that although phosphorus was limiting
in March and June nitrogen was limiting to primary production in
October.
C. Nutrient Controllability:
1. Point sources -
No known municipal or industrial point sources impacted
Lake Thunderbird during the sampling year. The Oklahoma
Department of Pollution Control (1975) states that the reser-
voir currently provides water to Oklahoma City, Del City,
Midwest City, and Norman; thus no discharges are allowed to
Little Creek upstream of Lake Thunderbird. Septic tanks
serving lake shore residences and state parks were estimated
to have contributed only 0.1% of the total phosphorus load
to the lake. A shoreline survey would be needed, however,
to determine the actual contributions of these sources.
2
The phosphorus loading of 0.32 g P/m /yr measured during
the sampling year is a little more than twice that proposed
by Vollenweider (1975) as a "eutrophic" loading. Any future
nutrient contributions should be carefully evaluated as to
their potential effect on the water quality of this lake.
-------
2. Nonpoint sources -
Gaged tributaries contributed 73.0% of the total phos-
phorus load to Lake Thunderbird and ungaged drainage areas
were estimated to have contributed 21.5%.
-------
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
means 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
Lake Thunderbird was sampled three times during the open-
water season of 1974 by means of a pontoon-equipped Huey heli-
copter. Each time, samples for physical and chemical parameters
were collected from three stations on the lake 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 sampled were 16.5 meters at Station 01, 8.2 meters at
Station 02, and 8.5 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
maximum depth for each site. Results of the phytoplankton counts
and chlorophyll ^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-
cornuturn, indicates that the potential primary productivity in
Lake Thunderbird was low at the times of assay sample collection
(03/30/74, 10/23/74). However, if nutrients were not lost between
sampling and analysis, the control yield would likely have been
higher. In both assays, there was a significant increase in yield
over that of the control when orthophosphorus was added, indicating
phosphorus limitation. The addition of nitrogen alone to the
spring sample did not result in an increase in yield over that of
the control, although a slight increase was noted in the fall sample
with nitrogen addition.
Mean inorganic nitrogen to orthophosphorus (N/P) ratios in
the lake data were 17/1 and 14/1 in the spring and summer, suggesting
phosphorus limitation, but 10/1 in the fall, suggesting nitrogen
was the primary limiting nutrient on that sampling occasion.
-------

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 pro-
vided 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
immediate drainage" ("II" of USGS) were estimated by using the mean
2
annual nutrient loads, in kg/km /year, in Hog Creek, Rock Creek,
and Jim Blue Creek at Stations B-l, C-l, and D-l and multiplying
2
the means by the II area in km .

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 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.
