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
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.

STORE! NO. 4813
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Eagle Mountain Lake is meso-eutrophic;
i.e., moderately well supplied with nutrients and 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 lake.
Eagle Mountain Lake ranked third in overall trophic quality
when the 39 Texas reservoirs sampled in 1974 were compared using
a combination of six lake parameters*. Eleven of the water bodies
had less median total phosphorus, eight had less and two had the
same median dissolved orthophosphorus, two had less and three had
the same median inorganic nitrogen, eight had less mean chlorophyll
a_, and 25 had greater mean Secchi disc transparency. Some depres-
sion of dissolved oxygen with depth occurred at sampling station 2
in May.
Survey limnologists noted substantial shoreline beds of macro-
phytes in the upper end of the lake in March. Turbidity due to
suspended silt was observed throughout the lake in August.
B. Rate-Limiting Nutrient:
Due to significant changes in nutrient levels in the samples,
the algal assay results are not representative of conditions in
the lake at the times the samples were collected.
* See Appendix A.
-------
The lake data indicate that primary productivity was predom-
inately nitrogen-limited.
C. Nutrient Controllability:
1. Point sources —It is calculated that point sources con-
tributed only about 3% of the total phosphorus load to Eagle Moun-
tain Lake during the sampling year. The Springtown and Azle
municipal wastewater treatment plants were the major contributors.
During the sampling year, the lake received a total phosphorus
loading over three times that proposed by Vollenweider (Vollenweider
and Dillon, 1974) as a eutrophic loading (see page 14). However,
because of the large non-point contribution, it does not seem likely
i
that point-source phosphorus control would result in a significant
improvement in the trophic condition of the lake.
. 2. Non-point sources — It is calculated that non-point sources
contributed about 97% of the total phosphorus load to the lake
during the sampling year. The West Fork of the Trinity River con-
tributed nearly 83% of the total load, the minor tributaries and
immediate drainage contributed about 7%, Walnut Creek 3.5%, and
Ash Creek contributed about 2%.
The phosphorus export rates of the Eagle Mountain Lake tribu-
taries (see page 13) were somewhat high as compared to Texas streams
/
sampled elsewhere; e.g., the mean of the export rates of three tribu-
taries of nearby Possum Kingdom Reservoir* was 5 kg/km2/yr (range of
3 to 8 kg/km2/yr).

III. LAKE WATER QUALITY SUMMARY
Eagle Mountain Lake 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 four
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 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 5.2 meters at station 1, 12.8 meters at
station 2, 8.5 meters at station 3, and 1.8 meters at station 4.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

C. Limiting Nutrient Study:
Significant changes in nutrient levels occurred in the assay
samples during shipment from the field to the laboratory, and the
results are not indicative of conditions in the lake at the times
the samples were taken (03/07/74 and 10/30/74).
The lake data indicate that primary productivity was predom-
inately nitrogen-limited each sampling time (the mean inorganic
nitrogen to orthophosphorus ratios were less than 14 to 1). Phos-
phorus limitation occurred only at sampling station 1 in May and
-------
at station 3 in May and August (the N to P ratios were 17 to 1,
15 to 1, and 20 to 1, respectively).
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-
limitation 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 en-
riched 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 high
runoff month of April when two samples were collected at most of the
sites. 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 lake.
In this report, nutrient loads for sampled tributaries were
calculated using mean annual concentrations and mean annual flows.
Nutrient loads for outlet station B-l, which was sampled only four
times, were calculated using the mean annual concentrations at
outlet station A-l and the mean annual flow at station B-l. Tribu-
tary loads shown are those measured minus point-source loads, if any.
Nutrient loads for unsampled "minor tributaries and immediate
drainage" ("IT." of U.S.G.S.) were estimated using the mean concentra-
tions in Ash Creek at station C-l and the mean annual ZZ flow.
The operators of the Azle, Springtown, and Fort Worth Boat Club
wastewater treatment plants provided monthly effluent samples and cor-
responding flow data.

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.
