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 [§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. 4839
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Whitney Reservoir 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 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.
Whitney Reservoir ranked fifteenth in overall trophic quality
when the 39 Texas reservoirs sampled in 1974 were compared using
a combination of six water quality parameters*. Fourteen of the
reservoirs had less median total phosphorus, eight had less and
two had the same median dissolved orthophosphorus, 18 had less
and one had the same median inorganic nitrogen, 11 had less mean
chlorophyll a_, and eight had greater mean Secchi disc transparency.
Marked depression or depletion of hypolimnetic dissolved oxygen
occurred at all sampling stations in May and August.
Survey limnologists noted submerged vegetation in the shallows
near stations 1 and 2 in August. Reportedly, aquatic vegetation
is not a problem in this reservoir, however (Anonymous, 1973).
* See Appendix A.
-------
B. Rate-Limiting Nutrient:
The algal assay results are not considered representative of
conditions in the reservoir at the time of sampling due to sig-
nificant nutrient changes in the sample during shipment from the
field to the laboratory. The reservoir data indicate phosphorus
limitation at all stations in March and May but nitrogen limitation
at all but station 1 in November.
C. Nutrient Controllability:
1. Point sources—During the sampling year, point sources
contributed 9.7% of the total phosphorus load to Whitney Reservoir.
The wastewater treatment plants at Cleburne contributed an estimated
5.6%, the facility at Granbury contributed an estimated 2.2%, and
three other facilities, along with septic tanks serving shoreline
dwellings, collectively contributed an estimated 1.9%.
The present phosphorus loading of 1.24 g/m2/year is 1.9 times
that proposed by Vollenweider (Vollenweider and Dillon, 1974) as
a eutrophic loading (see page 16), but even complete removal of
phosphorus at the listed point sources would leave a loading of
1.12 g/m2/yr. However, regardless of the applicability of
Vollenweider's eutrophic level to Texas water bodies, Whitney
Reservoir is phosphorus-limited much of the time, and point source
phosphorus control could help slow the rate of eutrophication,
particularly if a significant portion of the phosphorus export
of the Nolan River proves to be controllable (see below).
-------
2. Non-point sources—It is estimated that the phosphorus
contribution of non-point sources accounted for 90.3% of the total
load impacting Whitney Reservoir. The Brazos River contributed
56.2%, Nolan River contributed 31.2%, and two other gaged tribu-
taries collectively contributed 0.5%. Ungaged minor tributaries
and immediate drainage were estimated to have contributed 1.0%.
The phosphorus export rate of Nolan River was from 20 to 40
times greater than the rates of the other reservoir tributaries
(see page 15). This is indicative of an underestimation of the
contribution of the wastewater treatment plants at Cleburne.

III. WATER QUALITY SUMMARY
Whitney Reservoir 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 a number of depths at four
stations on the reservoir (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 visit, 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 30.2 meters at station 1,
22.3 meters at station 2, 21.9 meters at station 3, and 12.8 meters
at station 4.
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).

C. Limiting Nutrient Study:
Due to significant nutrient changes in the samples during
shipment from the field to the laboratory, the algal assays are
not considered representative of conditions in the reservoir at
sampling time. The reservoir data indicate that phosphorus was
the limiting nutrient in March and May; i.e., the mean inorganic
nitrogen/orthophosphorus ratios were 18/1 or greater at all
stations. However, nitrogen limitation is indicated in November
at stations 2, 3, and 4 (nearest the point sources), and phos-
phorus limitation is indicated at station 1; i.e., the mean

inorganic nitrogen/orthophosphorus ratios were 12/1 or less
at stations 2, 3, and 4 and 15/1 at station 1.
Nitrogen limitation, as indicated by in-lake nitrogen to
phosphorus ratios, does not necessarily mean that the trophic
condition of the lake can be improved by controlling nitrogen
inputs. In many cases, the apparent condition of nitrogen-limi-
tation results from excessive phosphorus input from point sources
and is often accompanied by a corresponding increase in primary
production. In such cases, the reversal of the enriched condition
depends upon phosphorus control, not nitrogen control.

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 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 at stations B-l and C-l, in kg/km2/year, and multi-
plying the means by the II area in km2.
The operators of the Cleburne, Granbury, Glen Rose, Blum, and
Whitney wastewater treatment plants did not participate in the Survey;
nutrient loads from these sources were estimated at 1.134 kg P and
3.401 kg N/capita/year, and flows were estimated at 0.3785 m3/capita/
day.

F. 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.
