FOREWORD
The National Eutrophicatlon 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, 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 [§303(e)], water qualitv 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.
-------
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.

STORE! NOS. 2217 and 2201
I. CONCLUSIONS
A. Trophic Condition:*
On the basis of field observations and Survey data,
Lakes Vernon and Anacoco are considered mesotrophic. Of
the 19 Louisiana lakes sampled in 1974, 18 had higher
median total and orthophosphorus values, and 8 had higher
inorganic nitrogen than Lake Vernon. Chlorophyll a_ levels
ranged from 3.0 yg/1 to 7.8 yg/1 with a mean of 4.9 yg/1.
Potential for primary production as measured by algal assay
control yield was low. Marked depression of dissolved oxy-
gen with depth occurred at Station 03 during May and Novem-
ber sampling. Survey limnologists reported heavy concentra-
tions of floating macrophytes at the north end of the lake.
Of the 19 Louisiana lakes, 16 had higher median total
and orthophosphorus levels, and 14 had higher inorganic
nitrogen levels than Anacoco Lake. Chlorophyll a^ ranged
from 5.1 yg/1 to 13.6 yg/1, with a mean of 8.7 yg/1. Although
the lake has a past record of problem macrophytes, Survey
limnologists did not observe any nuisance conditions during
their visits to Anacoco Lake.
*See Appendix E.
-------
B. Rate Limiting Nutrient:
Algal assay results indicate that Lakes Vernon and Anacoco
were growth limited by available phosphorus levels during both
spring and autumn sampling. Mean inorganic nitrogen to ortho-
phosphorus (N/P) ratios for Lake Vernon were 26/1, 28/1, and
23/1 for the three sampling seasons, indicating phosphorus limi-
tation. However, mean N/P ratios for Anacoco Lake were 13/1 or
less on all three sampling occasions, suggesting nitrogen limi-
tation.
C. Nutrient Controllability:
1. Point sources -
There were no known point sources impacting Lakes Vernon
and Anacoco during the sampling year. The mean annual phos-
2
phorus loading of 0.24 g P/m /yr for Lake Vernon was less
than the "oligotrophic" level proposed by Vollenweider (1975)
for a lake with such volume and detention time. If this low
phosphorus loading can be maintained, the existing excellent
water quality of Lake Vernon should persist.
2
The phosphorus loading of 0.61 g P/m /yr for Anacoco Lake
is greater than Vollenweider's "oligotrophic" level but less
than his "eutrophic" value. However, loading calculations
yield a net export of both phosphorus and nitrogen from
Anacoco Lake, suggesting sampling was not adequate to depict
-------
actual loading and export rates. This export could be
attributed to inaccurate estimation of loading values
for the unmeasured tributaries (see Section IV-E) or to
undetected discharges reaching the lake from unknown
municipal or industrial sources. Additional sampling is
needed before a nutrient budget for Anacoco Lake can be
determined; nevertheless, any addition to the present
phosphorus loading should be carefully evaluated in order
to maintain the lake's existing high quality.
2. Nonpoint sources -
The mean annual phosphorus loads from measured tribu-
taries amounted to 60.7% and 85.7%, respectively, of the
total loads to Lakes Vernon and Anacoco. The estimated
phosphorus loads from ungaged drainage areas were respec-
tively 31.6% and 11.0%.

II. LAKE AND DRAINAGE BASIN CHARACTERISTICS
Lake and drainage basin characteristics are itemized
below. Lake morphometry was provided by the State of Louisi-
ana; tributary flow data were provided by the Louisiana Dis-
trict Office of the U.S. Geological Survey (USGS). Outlet
drainage area includes the lake surface area. Mean hydraulic
retention time was obtained by dividing the lake volume by
mean flow of the outlet. Precipitation values are estimated
by methods as outlined in National Eutrophication Survey (NES)
Working Paper No. 175. A table of metric/English conversions
is included as Appendix A.

III. LAKE WATER QUALITY SUMMARY
Lakes Vernon and Anacoco were sampled three times during
the open-water season of 1974 by means of a pontoon-equipped
Huey helicopter. Each time, samples for physical and chemical
parameters were collected from three stations on Lake Vernon
and two stations on Anacoco Lake, and from one or more depths at
each station (see maps, pages v-vi). During each visit, depth-
integrated samples were collected from each station for chloro-
phyll ^analysis and phytoplankton identification and enumera-
tion. During the first and last visit, 18.9-liter depth-
integrated samples were composited for algal assays. Maximum
depths sampled were:
Lake Vernon Anacoco Lake
Station 01 9.1 4.3 meters
Station 02 3.7 2.1 meters
Station 03 9.1 meters
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 III-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 III-B.
Results of the limiting nutrient study are presented in III-C.

2. Discussion -
The control yields of the assay alga, Selenastrum
capricornutum, indicate that the potentials for primary
production in Lakes Vernon and Anacoco were low to mod-
erate at the times of assay sample collection. In as-
says for both lakes, for both sampling occasions, growth
response with the additions of nitrogen indicated phos-
phorus limitation. Maximum growth yields were achieved
with the simultaneous addition of phosphorus and nitro-
gen.
Mean N/P ratios for Lake Vernon were 26/1, 28/1, and
23/1 for the spring, summer, and fall sampling seasons,
indicating phosphorus limitation. Mean N/P ratios for
Anacoco Lake were 9/1, 13/1, and 9/1 for the three sam-
pling seasons, suggesting nitrogen or co-limitation.
It should be noted that significant chemical changes
took place in Louisiana lake samples between collection
and algal assay. The assay data should be considered in
this context and until such differences are resolved, used
with caution for any prediction of actual lake conditions.
Such chemical changes are likely to alter the control
yield as well as modifying the N/P ratio.

IV. NUTRIENT LOADINGS
(See Appendix D for data)
For the determination of nutrient loadings, the Louisi-
ana National Guard collected monthly near-surface grab sam-
ples from each of the tributary sites indicated on the maps
(pages v-vi), except for the high runoff month of February (also
March and April for Lake Vernon) when two samples were col-
lected. Sampling was begun in June 1974. Sampling for Lake
Vernon was completed in May 1975 and for Anacoco Lake, in
March 1975.
Through an interagency agreement, stream flow estimates
for the year of sampling and a "normalized" or average year
were provided by the Louisiana 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 a USGS computer pro-
gram 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
immediate drainage" ("II" of USGS) were estimated by using the
mean annual nutrient loads, in kg/km^/yr, at Stations 2217C-1,
D-l, and 2201A-2, B-l, C-l, and F-l, and multiplying the means
by the II area in km^.

D-l Jurdon Creek 0.018 0.543
E-l Wyatt Creek 0.118 0.557
It should be noted that phosphorus levels in Wyatt Creek
were substantially higher than values found in other tributaries
impacting Anacoco Lake (other tributary total phosphorus values
ranged from 0.018 mg/1 to 0.038 mg/1). As the Wyatt Creek contri-
butions were not incorporated into the estimates, it is likely
that the ZZ phosphorus loading for Anacoco Lake is greatly
underestimated, resulting in the apparent phosphorus export from
that lake. Nitrogen levels for both tributaries D-l and E-l
were slightly lower than those observed in other streams of the
Anacoco Lake drainage basin.

F. 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
water would become eutrophic or remain eutrophic; his "oligotrophic"
loading is that which would result in the receiving water remaining
oligotrophic or becoming oligotrophic if morphometry 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.
