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
reservol 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 0 f 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
enviror nental agencies with specific information for basin
planning [ 3O3(e)], water quality criteria/standards review
L 3O3(c)], clean lakes [ 3l4(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. ‘tikewise, 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 PICKWICK LAKE, ALABAMA
STORET NO. 0109
I. CONCLUSIONS
A. Trophic Condition:*
Pickwick 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 deter-
mined by its actual or potential impact upon designated bene-
ficial water uses of each lake.
Algae blooms were reported by Survey limnologists during
the field investigation. Water clarity is low, being “green-
ish and turbid. Of the 11 Alabama lakes sampled in 1973,
only two had higher median total P and inorganic N levels, and
none had higher median dissolved P. The algal assay results
indicated the potential primary productivity in Pickwick Lake
was high when sampled.
B. Rate-Limiting Nutrient:
Algal assay results and the high field ratio of inorganic
nitrogen to orthophosphorus (N/P) at the spring sample collec-
tion indicates primary limitation by phosphorus. However, low
N/P ratios were detected during the sumer and fall sampling
periods, suggesting nitrogen limitation.
*See Appendix E.

C. Nutrient Controllability:
1. Point sources -
The mean annual phosphorus contribution from known
point sources was estimated to be 10.4% of the total load
reaching Pickwick Lake during the sampling year. The
Muscle Shoals National Fertilizer Development Center con-
tributed 7.7% of the total load.
The present calculated loading of 16.09 g P/m 2 /yr is
about five times that proposed by Vollenweider (1975) as
eutrophic for a lake with such volume and retention time.
However, Vollenweider’s model may not apply to lakes with
short hydraulic retention times; the retention time of
Pickwick Lake is only nine days. Loading calculations
yield a net export of phosphorus from Pickwick Lake, indi-
cating that sampling was not adequate to depict actual
loading and export rates. Additional sampling and an
evaluation of current land use and presently undetected
industrial or municipal sources is necessary before a nutri-
ent budget for the lake can be determined.
2. Nonpoint sources -
The mean annual phosphorus load from “nonpoint” sources
was about 89.6% of the total reaching Pickwick Lake. The
Tennessee River contributed 85.6% of the total load, and
ungaged drainage areas were estimated to have contributed

-------

0.4%. Included in this Tennessee River “nonpoint” contri-
bution is the entire chain of impoundments upstream from
Pickwick Lake. An evaluation of the nutrient control re-
quirements for the upstream sources in the Tennessee River
watershed is needed as well as a determination of control
requirements for Pickwick Lake.
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 con-
trol technology and subsequent establishment of phosphorus
limitation within the water body.

III. LAKE WATER QUALITY SUMMARY
Pickwick Lake was sampled three times during the open-
water season of 1973 by means of a pontoon-equipped Huey heli-
copter. Each time, samples for physical and chemical para-
meters were collected from six stations on the lake (one sta-
tion was sampled once, three stations were sampled twice, and
two stations were sampled three times) and from a number of
depths at each station (see map, page v). During each visit,
depth-integrated samples were collected from each station for
chlorophyll a analysis and phytoplankton identification and
enumeration. During the first visit, two 18.9-liter depth-
integrated samples were composited from Stations 1 through 3,
and from Stations 5 through 6 for algal assays. Maximum depths
sampled were 23.2 meters at Station 1, 9.4 meters at Station 2,
9.1 meters at Station 3, 9.8 meters at Station 4, 15.2 meters
at Station 5, and 9.4 meters at Station 6. For a more detailed
explanation 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 Ill-B.
Results of the limiting nutrient study are presented in Ill-C.

3. Discussion -
The control yields of both algal assays with Selenastrum
capricornutum indicate that the potential primary productivity
of Pickwick Lake was high at the time assay samples were
collected. Also, the significantly increased yields with
increased levels of orthophosphate in both assays indicate
the lake was phosphorus limited at the time of sample collec-
tion. Simultaneous addition of nitrogen and phosphorus
spikes produced the maximum yield obtained for each assay.
No growth response accompanied spikes of nitrogen alone.
The N/P ratio in the field samples was about 19/1, in-
dicating that the lake was phosphorus limited at the time
assay samples were collected. However, N/P field ratios of
about 12/1 and 10/1 for the sumer and fall samples respec-
tively suggest primary limitation by nitrogen (an N/P ratio
of 14/1 or greater generally reflects phosphorus limitation).

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 pro-
vided by the Alabama District Office of the USGS for the tributary
sites nearest the lake.
In this report, nutrient loads for sampled tributaries were
determined by using a modification of the USGS computer program
for calculating stream loadings. Nutrient loads indicated for
tributaries are those measured minus known point source loads, if
any.
Nutrient loadings for unsampled “minor tributaries and ime-
diate drainage” (“ZZ” of USGS) were estimated by using the mean
annual nutrient loads, in kg/km 2 /year, at Stations C(1), D(l),
F(1), G(l), H(l), K(l), L(l), M(l), N(l), and Q(1), and multiplying
the means by the ZZ drainage area in km 2 .
Nutrient loads for the cities of Sheffield, Florence, Muscle
Shoals, Tuscumbia, and Cherokee wastewater treatment plants were

-------
13
estimated at 1.134 kg P and 3.401 kg N/capita/year. Annual
nutrient loads for the National Fertilizer Development Center
were provided by the plant operator (personal communication).

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 morphonietry permitted. A mesotrophic 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.
Total Yearly
Phosphorus Loading
(gJm 2 /yr)
Estimated loading for Pickwick Lake 16.09
Vollenweider’s eutrophic loading 3.43
Vollenweider’s oligotrophic loading 1 .71
