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
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 Still house Hollow Reservoir is
mesotrophic; i.e., moderately supplied with nutrients and mod-
erately 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.
Although it ranked twelfth in overall trophic quality when the
39 Texas reservoirs sampled in 1974 were compared using a combi-
nation of six water quality parameters*, the reservoir is phos-
phorus limited. If inorganic nitrogen is omitted, Stillhouse
Hollow Reservoir ranks eighth in overall quality.
Four of the reservoirs had less and one had the same median
total phosphorus, 18 had less and one had the same median dissolved
orthophosphorus, 24 had less and one had the same median inorganic
nitrogen, three had less mean chlorophyll a_, and five had greater
mean Secchi disc transparency. Marked depression or depletion of
hypolimnetic dissolved oxygen occurred at sampling stations 1 and
2 in May and August, and depression with depth occurred at station
3 at those times.
* See Appendix A.
-------
Survey limnologists noted small patches of submerged macro-
phytes in the shallows at stations 2 and 3 in August.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Still house Hollow
Reservoir was phosphorus limited at the time the sample was col-
lected (03/13/74). The reservoir data indicate phosphorus limi-
tation at all sampling times.
C. Nutrient Controllability:
1. Point sources—During the sampling year, estimated point-
source phosphorus loads accounted for over 66% of the total input
to Still house Hollow Reservoir. The two wastewater treatment plants
at Lampasas collectively contributed an estimated 59.2%, and the
facility at Florence contributed an estimated 7.1%.
The present phosphorus loading of 0.37 g/m2/year is less than
that proposed by Vollenweider (Vollenweider and Dillon, 1974) as
a eutrophic loading but more than his oligotrophic loading (see
page 14). Because the reservoir is phosphorus limited, elimina-
tion or reduction of point-source phosphorus inputs could be con-
sidered a measure to maintain good water quality.
2. Non-point sources--Non-point sources contributed about 34%
of the total phosphorus load during the sampling year. The Lam-
pasas River contributed 24.8%, and the ungaged minor tributaries
and immediate drainage contributed an estimated 4.2% of the total.
The phosphorus export rate of the Lampasas River was less than
1 kg/km2 during the sampling year (page 13).

III. WATER QUALITY SUMMARY
Stillhouse Hollow 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 three
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 31.1 meters at station 1, 25.6 meters at
station 2, and 12.2 meters at station 3.
The sampling results are presented in full in Appendix D and are
summarized in the following table (the August nutrient samples were not
properly preserved and were not analyzed).

2. Discussion -
The control yield of the assay alga, Selena strum capri-
cornutum, indicates that the potential primary productivity
of Stillhouse Hollow Reservoir was low at the time the sample
was collected (03/13/74). The significant increase in yield
-------
with the addition of orthophosphorus and the lack of change
in yield when only nitrogen was added indicate phosphorus
limitation.
The reservoir data indicate phosphorus limitation in
March, May, and November (i.e., the mean inorganic nitrogen
to orthophosphorus ratios were 15 to 1 or greater).

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
calculated using mean annual concentrations and mean annual flows.
Nutrient loads shown are those measured minus point-source loads,
if any.
Nutrient loads in the diversion by the Brazos River Authority
were calculated using the mean concentrations in Lampasas River
(station A-l) and the total of the 1974 diversion in cubic meters.
Nutrient loads for unsampled "minor tributaries and immediate
drainage" ("ZZ" of U.S.G.S.) were estimated using the mean, con-
centrations in Trimmer Creek at station B-l and the mean annual
ZZ flow.
The operators of the waste treatment facilities of Lampasas and
Florence did not participate; nutrient loads from these sources were
-------
11
estimated at 1.134 kg P and 3.401 kg N/capita/year, and flows were esti-
mated 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.
