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)J, 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
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

STORE! NO. 4832
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Tawakoni is eutrophic;
i.e., well supplied with nutrients and quite productive.
Whether nutrient enrichment is beneficial or deleterious
depends on the actual or potential effect on the uses of the
lake. 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.
Lake Tawakoni ranked twenty-eighth when the 39 Texas reser-
voirs sampled in 1974 were compared using a combination of six
parameters* as an index to overall trophic quality. Twenty-six
of the reservoirs had less median total phosphorus, 25 had less
and three had the same median dissolved phosphorus, 11 had less
and one had the same median inorganic nitrogen, 30 had less mean
chlorophyll £, and 24 had greater mean Secchi disc transparency.
Marked depression of dissolved oxygen with depth occurred at
station 1 in August.
Survey limnologists observed surface concentrations of algae
at station 6 in March and noted the occurrence of emergent
See Appendix A.
-------
macrophytes in the shoreline shallows near stations 3 and
6 at that time. Blue-green algae were dominant in the
August phytoplankton sample (page 9).
Water milfoil is reported to be very abundant in some
places in the lake (Moczygemba, 1974), and aquatic macro-
phytes are a potential problem in the Cowleech Fork embay-
ment (Anonymous, 1974±?1).
B. Rate-Limiting Nutrient:
A significant loss of phosphorus occurred in the assay
samples between the time of collection (11/01/74) and the
beginning of the algal assays, and the results are not
representative of conditions in the lake at the time the
samples were taken. The lake data indicate nitrogen limi-
tation at all stations in March and November but phosphorus
limitation at all stations, except station 5, in May.
C. Nutrient Controllability:
1. Point sources—The phosphorus contribution of the
point sources considered in this report apparently amounted
to 23.9% of the total phosphorus load reaching the lake during
the sampling year. The City of Greenville contributed 20.9%,
and five other dischargers collectively contributed 3.0% of
the total load.
The present phosphorus loading of 0.91 g/m 2/yr is three
times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 16). While even complete
-------
removal of phosphorus at the listed point sources probably
would still leave a loading in excess of the eutrophic loading,
it is likely that a high degree of phosphorus removal at the
Greenville wastewater treatment plant would result in improve-
ment in the quality of the Cowleech Fork embayment, particularly
in view of the probable error in the "non-point" load of the
Cowleech Fork (see below).
2. Non-point sources—It is calculated that over 76% of
the total phosphorus load reaching the lake during the sampling
year was contributed by non-point sources, but it is probable
that the actual non-point load was less than indicated.
The Cowleech Fork apparently contributed 45% of the total
phosphorus load (page 14) and had an exceptionally high export
rate of 175 kg P/km2 (page 16). However, the high nutrient
concentrations measured at station C-l (Appendix E) probably
resulted from the relatively large amounts of Greenville effluent
in the stream at that point in proportion to the total stream
flow.
During the sampling year, the mean Greenville discharge was
0.103 m3/sec, and the mean stream flow at the times the samples
were taken was 0.482 m3/sec (highest [30.299 m3/sec] and lowest
[0.003 m3/sec] flows omitted; see Appendix C). On a yearly mean
basis, then, the Greenville effluent would account for over 21%
of the flow in the stream and, during dry periods, would account
-------
for essentially all of the flow in the stream. In this regard,
personnel of the Texas Water Quality Board calculated that 71%
of the Cowleech Fork flow in January, 1974, was Greensville
effluent (Anonymous, 1974[?]).
Therefore, the true non-point phosphorus load of the Cowleech
Fork must have been much less than was measured; and, conversely,
the proportion of the total load contributed by point sources
must have been more that indicated above. For example, if the
actual phosphorus export rate of the Cowleech Fork was the same
as the somewhat high South Fork rate (48 kg/km2/yr), the non-
point contribution of the Cowleech Fork would have been 16,780 kg,
a difference of 44,335 kg; and the proportion of point-source
contribution would be increased from 23.9% to 35.6% of the total
load.

III. WATER QUALITY SUMMARY
Lake Tawakoni was sampled four times in 1974 by means of a pontoon-
equipped Huey helicopter. Each time, samples for physical and chemical
parameters were collected from two or more depths at six stations on the
lake (see map, page vi). During each visit, a single depth-integrated
(4.6 m or near bottom to surface) sample was composited from the stations
for phytoplankton identification and enumeration; and during the November
visit, two 18.9-liter depth-integrated samples were 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 13.7 meters at station 1, 10.7 meters at station 2, 7.6
meters at station 3, 9.1 meters at station 4, 4.6 meters at station 5,
and 3.4 meters at station 6.
The sampling results are presented in full in Appendix D and are
summarized in the following table (the August nutrient samples were not
preserved properly and were not analyzed).

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 month
of June when two samples were collected. Sampling was begun in Sep-
tember, 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 lake, except for the South Fork of the
Sabine River (station D-l). The drainage area of this stream and
the flow (mean of 15 years) were obtained from U.S.G.S. records
(Anonymous, 1975).
Except for the South Fork, nutrient loads in sampled tributaries
were determined by using a modification of a U.S. Geological Survey
computer for calculating stream loadings*. The nutrient loads in the
South Fork were calculated using mean concentrations and the mean flow.
Also, the nutrient loads in the water diverted by the Sabine River
Authority were calculated using the mean nutrient concentrations at
lake sampling station 1 and the mean diversion flow (Gray, 1976).
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 adjusted nutrient
* See Working Paper No. 175.

loads at station B-l, in kg/km2/year, and multiplying by the ZZ area
in km2.
The operators of the Caddo Mills, Celeste, Greenville, Quinlan,
Royse City, and Wind Point Park wastewater treatment plants provided
monthly effluent samples and corresponding flow data.
Four additional municipal wastewater treatment plants, with a
combined effluent flow of 268 m3/day, discharged in the drainage
during the sampling year; however, these plants do not significantly
influence the quality of the receiving streams and probably have
little effect on the lake (Anonymous, 1974[?]).

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.
Total Phosphorus Total Nitrogen
Total Accumulated Total Accumulated
grams/mVyr 0.91 0.80 6.3 4.5
Vollenweider phosphorus loadings
(g/mz/yr) based on mean depth and mean
hydraulic retention time of Lake Tawakoni:
"Dangerous" (eutrophic loading) 0.30
"Permissible" (oligotrophic loading) 0.15
