FOREWORD
The National Eutrophication Survey was initiated in 1972 in
response to an Administration comitnient to Investigate the nation-
wide threat of accelerated eutrophication to freshwater lakes and
reservoi r.s.
OBJECTIVES
The Survey was designed to develop, in conjunction with state
environmental agencies, Information on nutrient sources, concen-
trations, 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 nonpoint source pollution abatement in lake water-
sheds.
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
watershed 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 [ 3O3(e)], water quality criteria/standards review
[ 3O3(c)], clean lakes [ g314(a,b)], and water quality monitoring
[ lO6 and §305(b)] activities mandated by the Federal Water
Pollution Control Act Amendments of 1972.
-------
111
Beyond the single lake analysis, broader based correlations
between nutrient concentrations (and loading) and trophic condition
are being made to advance the rationale and data base for refine-
ment of nutrient water quality criteria for the Nation’s freshwater
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 the U.S. Environmental Protection
Agency and to augment plans implementation by the states.

REPORT ON WILSON LAKE, ALABAMA
STORET NO. 0114
I. CONCLUSIONS
A. Trophic Condition:*
Wilson Lake is considered eutrophic, i.e., nutrient
rich and highly productive, based upon field observations
and analysis of Survey data. Whether such nutrient enrich-
ment is to be considered beneficial or deleterious is
determined by its actual or potential impact upon desig-
nated beneficial water uses of each lake.
Of the 11 Alabama lakes surveyed in 1973, 7 had less
median total and median dissolved orthophosphorus, 6 had
less median inorganic nitrogen, 7 had less mean chloro-
phyll a, and 2 had greater Secchi disc transparency.
Chlorophyll a levels ranged from a low of 2.1 pg/i in
the spring to a high of 19.1 pg/i in the fall. Phyto-
plankton genera identified were generally pollution tole-
rant forms.
B. Rate-Limiting Nutrient:
Algal assay results indicate that Wilson Lake was
limited by available phosphorus levels. The ratios of
inorganic nitrogen to orthophosphorus (N/P) in sampled
*See Appendix E.
-------
2
waters indicate primary limitation by phosphorus during the
spring (22/1) and summer (23/1) sampling periods and nitrogen
limitation during the fall (12/1).
C. Nutrient Controllability:
1 . Point sources -
The mean annual phosphorus load from point sources
was estimated to be less than 1% of the total load directly
reaching Wilson Lake. The cities of Courtland and Moulton
contributed this load.
Nutrient loading to Wilson Lake is excessive, exceed-
ing Vollenweider’s (1975) proposed eutrophic loading for
phosphorus by eight times, and exceeding the oligotrophic
loading by sixteen times for a lake of such mean depth and
hydraulic retention time. However, it should be noted that
Vollenweider’s model may not fully apply to lakes with short
hydraulic retention times (six days for Wilson Lake).
2. Nonpoint sources -
Loading to Wilson Lake is largely uncontrollable, with
the Tennessee River contributing approximately 97% of the
phosphorus and nitrogen input to the lake. Surrounding
land uses and point sources upriver contributing to the
Tennessee River load should be analyzed before a nutrient
budget for the lake is defined.
-------
3
In general, few lakes are nitrogen limited as a
result of low nitrogen. Rather, excessive phosphorus
levels shift limitations to nitrogen or other factors.
Regardless of the primary nutrient limitation suggested
by either algal assay or nutrient ratios, the most feasible
approach to nutrient control, if desirable, is through
available phosphorus control technology and subsequent
establishment of phosphorus limitation within the water
body.

III. LAKE WATER QUALITY SUMMARY
Wilson Lake was sampled three times during the open-
water season of 1973 by means of a pontoon-equipped Huey
helicopter. Each time, samples for physical and chemical
parameters were collected from three stations on the lake
(Station 1 was sampled three times, Stations 2 and 3 were
sampled twice) and from a number of depths at each station
(see map, page v). During each visit, depth-integrated sam-
ples were collected from each station for chlorophyll a
analysis and phytoplankton identification and enumeration.
During the first visit, a single l8.9-liter depth-integrated
sample was composited for algal assays. Maximum depths
sampled were 26.8 meters at Station 1, 13.7 meters at Station
2, and 5.2 meters at Station 3. For a more detailed explana-
tion of NES methods, see NES Working Paper No. 175.
The results obtained are presented in full in Appendix
C and are summarized in 111-A for waters at the surface and at
the maximum depth for each site. Results of the phytoplankton
counts and chlorophyll a determinations are included in 111-B.
Results of the limiting nutrient study are presented in Ill-C.

3. Discussion —
The control yield of the assay alga, Selenastrum capri-
cornutum , indicates that the potential for primary production
in Wilson Lake was high at the time of sampling. Increased
growth of the test alga in response to incremental additions
of orthophosphorus to and beyond 20 .ig/liter concentration
indicates that the lake was phosphorus-limited when sampled.
Spikes with nitrogen and phosphorus simultaneously resulted
in maximum yield. The addition of nitrogen alone did not
stimulate growth significantly when compared to the control
yield.
-------
10
The N/P ratio in the field samples suggests primary limi-
tation by phosphorus during the spring (22/1) and sumer (23/1)
sampling periods and nitrogen limitation during the fall (12/1).

IV. NUTRIENT LOADINGS
(See Appendix D for data)
For the determination of nutrient loadings, the Alabama
National Guard collected monthly near-surface grab samples from
each of the tributary sites indicated (see map, page v), except
for the high runoff months of January and February when two sam-
ples were collected. Sampling was begun in March 1973, and was
completed in February 1974.
Through an interagency agreement, stream flow estimates for
the year of sampling and a “normalized” or average year were
provided by the Alabama District Office of USGS for the tributary
sites nearest the lake.
In this report, nutrient loads for sampled tributaries except
the Tennessee River, at outlet Station A(1), were determined by
using a modification of a USGS computer program for calculating
stream loadings. Nutrient loads indicated for tributaries are those
measured minus known point source loads, if any. Nutrient loads
for Station A(1) were calculated using the mean annual flow and
nutrient concentrations in the Tennessee River at that site.
Nutrient loadings for unsampled “minor tributaries and imme-
diate drainage” (“ZZ” of USGS) were estimated by using the mean of
the nutrient loads, in kg/km 2 /year, at Station 8(1) and multiplying
the means by the ZZ area in km 2 .

E. Yearly Loadings:
In the following table, the existing phosphorus annual
loading is compared to the relationship proposed by Vollenweider
(1975). Essentially, his eutrophic loading is that at which
the receiving waters would become eutrophic or remain eutrophic;
his oligotrophic loading is that which would result in the
receiving water remaining oligotrophic or becoming oligotrophic
if ruorphometry permitted. A rnesotrophic loading would be
considered one between eutrophic and oligotrophic.
Note that Vollenweider’s model may not apply to lakes with
short hydraulic retention times or in which light penetration is
severely restricted by high concentrations of suspended solids
in the surface waters.
