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 [5303(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.
-------
Ill
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 & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Texas Water Quality Board
for professional involvement, to the Texas National Guard for
conducting the tributary sampling phase of the Survey, and to
those Texas wastewater treatment plant operators who voluntarily
provided effluent samples.
Hugh C. Yantis, Jr., Executive Director of the Texas Water
Quality Board, and John B. Latchford, Jr., Director, and the staff
of the Field Operations Division provided invaluable lake documen-
tation and counsel during the Survey, reviewed the preliminary
reports, and provided critiques most useful in the preparation of
this Working Paper series.
Major General Thomas Bishop, the Adjutant General of Texas,
and Project Officer Colonel William L. Seals, who directed the
volunteer efforts of the Texas National Guardsmen, are also grate-
fully acknowledged for their assistance to the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Possum Kingdom Reservoir is meso-
eutrophic; i.e., moderately-well supplied with nutrients and pro-
ductive. Whether nutrient enrichment is beneficial or deleterious
depends on the actual or potential effect on the uses of the
reservoir. In this regard, no nuisance conditions are known to
personnel of the Texas Water Quality Board and there is little
or no impairment of the designated beneficial uses of this water
body.
Possum Kingdom Reservoir ranked ninth when the 39 Texas reser-
voirs sampled in 1974 were compared using a combination of six
parameters*. Nine of the reservoirs had less and one had the
same median total phosphorus, 11 had less and six had the same
median dissolved orthophosphorus, two had less and three had the
same median inorganic nitrogen, 16 had less mean chlorophyll a^
and six had greater mean Secchi disc transparency. Marked depres-
sion or depletion of hypolimnetic dissolved oxygen occurred at
sampling stations 1, 2, 3 and 4 in May and August, and depression
or depletion.with depth occurred at the same stations in October.
* See Appendix A.
-------
B. Rate-Limiting Nutrient:
Due to significant losses of total phosphorus in the algal
assay samples from the times of collection to the beginning of
the assays, the results are not representative of conditions in
the reservoir at the times the samples were taken (03/08/74 and
10/30/74).
The reservoir data indicate nitrogen limitation at all stations
in March, phosphorus limitation at all stations except station 5 in
May, nitrogen limitation at all stations except station 4 in August,
and nitrogen limitation at all stations in October.
C. Nutrient Controllability:
1. Point sources—The point-source phosphorus contribution
amounted to 4.2% of. the total load reaching Possum Kingdom Reservoir
during the sampling year. The City of Graham contributed 3.9% of
the total load, the community of Bryson added 0.2%, and septic tanks
serving lakeside dwellings were estimated to have contributed 0.1%
of the total.
The present phosphorus loading of 2.70 g/m2/yr is four times
that proposed by Vollenweider (Vollenweider and Dillon, 1974) as
a eutrophic loading (see page 15). Regardless of the applicability
of Vollenweider's eutrophic level to Texas reservoirs, it is not
likely that elimination of point-source phosphorus would signifi-
cantly improve the trophic condition of the reservoir because of
the large non-point load.
-------
2. Non-point sources—Over 95% of the total phosphorus
input to Possum Kingdom Reservoir during the sampling year came
from non-point sources. The Brazos River contributed 91.1%;
Cedar Creek, 1.3%; and Rock Creek, 0.5% of the total load. The
ungaged tributaries were estimated to have contributed 2.2%.
The Brazos River, Cedar Creek, and Rock Creek had phosphorus
export rates of 3, 8, and 4 kg P/km2/yr, respectively (see page
14). These rates are slightly higher than two tributaries of
nearby Lake Brownwood* (1 and 3 kg P/krn2/yr) and higher than a
tributary of Lake Colorado City** (1 kg P/km2/yr).

III. WATER QUALITY SUMMARY
Possum Kingdom Reservoir was sampled four times during 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 five
stations on the reservoir in March and May and from six stations in
August and October (see map, page vi). 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 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 28.0 meters at station 1, 21.3 meters at
station 2, 15.2 meters at station 3, 19.8 meters at station 4, 7.9 meters
at station 5, and 9.8 meters at station 6.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

Limiting Nutrient Study:
There were significant losses of total phosphorus in the algal
assay samples from the time of collection to the beginning of the
assays. Therefore, the results are not representative of conditions
in the reservoir at the time the samples were collected in March
and October, 1974.

The reservoir data indicate a temporal and spatial combina-
tion of limiting nutrients. Following is a tabulation of the
mean inorganic nitrogen/orthophosphorus ratios for each of the
sampling stations and times with the indicated limiting nutrient
in parentheses. Note that station 5, closest to point sources,
was nitrogen limited at all sampling times, while the stations
further away were phosphorus limited at times.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Texas National
Guard collected monthly near-surface grab samples from each of the
tributary sites indicated on the map (page vi), except for the high
runoff months of April and May when two samples were collected.
Sampling was begun in September, 1974, and was completed in August,
1975.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Texas 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" ("II" of U.S.G.S.) were estimated using the means of the
nutrient loads, in kg/km2/year, at stations A-2, C-l, and D-l and
multiplying the means by the II area in km2.
The operator of the Bryson wastewater treatment plant provided
monthly effluent samples and corresponding flow data. The City
of Graham did not participate; nutrient loads from this source were
estimated at 1.134 kg P and 3.401 kg N/capita/year, and flows were
estimated at 0.3785 m3/capita/day.

E. 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.
