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 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.
-------
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, multivarlate 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 LAKE BISTINEAU, LOUISIANA
STORET NO. 2203
I. CONCLUSIONS
A. Trophic Condition:*
Survey data indicate that Lake Bistineau is eutrophic,
i.e., nutrient rich and highly productive. Whether such
nutrient enrichment is to be considered beneficial or dele-
terious is determined by its actual or potential impact upon
designated beneficial water uses of each lake. Of the 19
Louisiana lakes sampled in 1974, 9 had higher median total
phosphorus or inorganic nitrogen levels, and 6 had higher
median orthophosphorus values than Lake Bistineau. Low Secchi
disc visibility and high potential for primary productivity,
as measured by algal assay control yield, were reported.
Although there were.no visible algal blooms, there were emer-
gent and submerged macrophytes noted and chlorophyll a^ levels
ranged from 3.0 yg/1 to 46.6 yg/1 through the seasonal sampling,
Shampine (1971) reports that attempts have been made in
recent years to control the weed problem in Lake Bistineau by
lowering the water level in the late spring and keeping it low
until fall.
*See Appendix E.
-------
B. Rate-Limiting Nutrient:
Algal assay results indicate that Lake Bistineau was nitrogen
limited during the spring. Spikes with nitrogen or nitrogen and
phosphorus simultaneously resulted in increases of assay yield.
Addition of phosphorus alone did not stimulate a growth response.
The mean inorganic nitrogen to orthophosphorus (N/P) ratios in the
lake samples were 11/1 or less on all sampling occasions, also
suggesting nitrogen limitation.
C. Nutrient Controllability:
1. Point sources -
2
The mean annual phosphorus loading of 1.67 g P/m /yr to
Lake Bistineau is in excess of the eutrophic level proposed by
Vollenweider (1975) and four times greater than the oligotrophic
level for a lake with such volume and retention time. The
annual phosphorus load from the five known point sources was
estimated to be 24.2% of the total load reaching Lake Bistineau.
The Minden #1 plant contributed 5.9%, Minden #2 contributed 6.6%,
Springhill contributed an estimated 8.2% and the remaining two
plants an estimated 3.5% of the total phosphorus load.
In general, few lakes are nitrogen limited as a result of
low nitrogen. Rather, excessive phosphorus levels shift limi-
tation 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.
2. Nonpoint sources -
The mean annual phosphorus load from measured tributaries
amounted to 68.8% of the total load to Lake Bistineau. Bayou
Dorcheat contributed 54.0% of the total annual nutrient load
and ungaged tributaries were estimated to have contributed
5.6%. Background loading to Boone Creek is approximately four
times higher than the values encountered for unimpacted streams
This high loading is probably attributable to the fact that
Boone Creek flows through the Louisiana Ordnance Plant.
-------
II. LAKE AND DRAINAGE BASIN CHARACTERISTICS
Lake and drainage basin characteristics are itemized below.
Lake morphometry data was provided by the State of Louisiana.
Tributary flow data were provided bythe Louisiana District Office
of the U.S. Geological Survey (USGS) (outlet drainage area in-
cludes the Take surface area). Mean hydraulic retention time
was obtained by dividing the lake volume by the mean flow of the
outlet. Precipitation values are estimated by methods as out-
lined in National Eutrophication Survey (NES) Working Paper No. 175.
A table of metric/English conversions is included as Appendix A.
A. Lake Morphometry:
1. Surface area: 69.67 km2.
2. Mean depth: 2.1 meters.
3. Maximum depth: 7.6 meters.
4. Volume: 148.019 x 106 m3.
5. Mean hydraulic retention time: 42 days.

III. LAKE WATER QUALITY SUMMARY
Lake Bistineau was sampled three times during the open-
water season of 1974 by means of a pontoon-equipped Huey heli-
copter. Each time, samples for physical and chemical parameters
were collected from four stations on the lake and from one or
more depths at each station (see map, page v). During each
visit, depth-integrated samples were collected from each station
for chlorophyll ^analysis and phytoplankton identification and
enumeration. During the first and last visits, 18.9-liter depth-
integrated samples were composited for algal assays. Maximum
depths sampled were 1.8 meters at Station 01, 3.4 meters at
Station 02, 3.4 meters at Station 03, and 1.5 meters at Station 04,
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 yield of the assay alga, Selenastrum capri-
cornutum, indicates that the potential for primary production
was high in Lake Bistineau during spring sampling. A response
in assay yield to the addition of nitrogen as well as the lack
of response to the addition of phosphorus indicates nitrogen
limitation. Maximum yield was achieved with the simultaneous
addition of both nutrients.
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 predictions of actual lake conditions. Such
chemical changes are likely to alter the control yield as well
as modifying the N/P ratio. The autumn algal assay results have
not been included in this report as these substantial changes
in nutrient levels have removed their information value.
The N/P ratios in the field samples of 11/1 or less on all
sampling occasions suggest primary limitation by nitrogen (a
mean N/P ratio of 14/1 or more generally reflects phosphorus
limitation).
-------

IV. NUTRIENT LOADING
(See appendix D for data)
For the determination of nutrient loadings, the Louisiana
National Guard collected monthly near-surface grab samples from
each of the tributary sites indicated on the map (page v), except
for the high runoff months of February, March, and April when
two samples were collected. Sampling was begun in June 1974, and
was completed in May 1975.
Through an interagency agreement, stream flow estimates for
the year of sampling and a "normalized" or average year were pro-
vided by the Louisiana District Office of the USGS for the tribu-
tary 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
immediate drainage" ("ZZ" of USGS) were estimated by using the
mean annual of the nutrient loads (in kg/km^/year) at Stations
B-l, E-l, and G-l at Clarke Bayou, Brushy Creek, and Toulon
Bayou, respectively, and multiplying the means by the ZZ area in
km2.
-------

The operator of the Minden #2 wastewater treatment plant
provided monthly effluent samples and corresponding flow data.
Nutrient loads for the Minden #1, Springhill, Cullen and Cotton
Valley wastewater treatment plants were estimated at 1.134 kg/P
and 3.401 kg N/capita/year.

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 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 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.
Total Yearly
Phosphorus Loading
