FOR EWORD
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 rs.
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)J, 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.
-------
•I11
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 BAYOU D’ARBONNE LAKE, LOUISIANA
STORET NO. 2211
I. CONCLUSIONS
A. Trophic Condition:*
Based on Survey data and field observations Lake
Bayou D’Arbonne is considered meso-eutrophic. :Secchj disc
readings had a mean of 106 cm, and potential for primary
productivity as measured by algal assay control yield was
low. Chlorophyll a values ranged from 2.0 pg/i in the fall
to 13.0 pg/i in the sun ner, with a mean of 6.8 ig/1. Of
the 19 Louisiana lakes sampled in 1974, 14 had higher median
total phosphorus, 9 had higher median inorganic nitrogen, and
10 had higher median orthophosphorus levels than Bayou
D’Arbonne Lake.
Shampine (1971) reported that during the summer there are
significant quality changes in the lower part of the lake
including depletion of dissolved oxygen, ‘production of hydro-
gen sulfide and increases in the concentrations of iron and
dissolved solids.
‘kSee Appendix E.

B.. Rate-Limiting Nutrient:
Algal assay results indicate that Bayou D’Arbonne Lake
was limited by available phosphorus. Spikes with phosphorus
alone or phosphorus and nitrogen simultaneously resulted in
increases in assay yield. Addition of nitrogen alone did not
stimulate a growth response. The ratio of available nitrogen
to orthophosphorus (NIP) in sampled waters indicates nitrogen
limitation during the spring and fall and phosphorus limitation
during the summer.
C. Nutrient Controllability:
1. Point sources -
Nutrient loading to Lake Bayou D’Arbonne is In excess
of the eutrophic level proposed by Volienweider (1975) and
approximately three times greater than the oligotrophic
level for a lake of such volume and detention time. The mean
annual phosphorus load from point sources was estimated to be
30.8% of the total load reaching the lake. Of the point source
load, the city of Ruston contributed a total of 26.8% from two
wastewater treatment plants. The remaining four known point
sources contributed a total of 4.0% of the total load. Reduc-
tion of known point sources would reduce the phosphorus load-
ings to the lake to slightly below the eutrophic Vollenweider
level.

2. Nonpoint sources -
Nonpoint sources contributed 67.8% of the total load
to Lake Bayou D’Arbonne. Corney Creek contributed 26.5% and
the Middle Fork Bayou D’Arbonne contributed 14.1%. The load-
ing from ungaged tributaries was estimated to be 14.3% of
the total load. Loading calculations for Lake Bayou D’Arbonne
yield a net export of nitrogen, indicating sampling was not
adequate to accurately depict actual nitrogen loading and ex-
port rates.

P1. LAKE AND DRAINAGE BASIN CHARACTERISTICS
Lake and drainage characteristics are itemized below. Lake
surface area and mean depth were provided by the State of Loulsi-
ana. Maximum depth was obtained from contour maps provided by the
Louisiana Stream Control Conunission. Tributary flow data were pro-
vided by the Louisiana District Office of the U.S Geological Survey
(USGS) (outlet drainage area includes the lake surfacearea). 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 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
Bayou D’Arbonne Lake was 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 col-
lected 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 chloro-
phyll a analysis and phytoplanktori identification and enumeration.
During the first and last visits, 18.9-liter depth-integrated sam-
ples were composited for algal assays. Maximum depths sampled were’
4.6 meters at Station 01, 11.0 meters at Station 02, 7.0 meters at
Station 03, and 0.9 meters at Station 04. For a more detailed ex-
planation of NES methods, see NES Working Paper No. 175.
The results obtained are presented in full in Appendix C and
are summarized in Ill-A for waters at the surface and at the maxi-
mum 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.

C. Limiting Nutrient Study:
1. Autoclaved, filtered, and nutrient spiked -
a. 03/21/74
The control yield of the assay alga, Selenastrum capri-
cornutum , indicates that the potential for primary productivity
was low on Bayou D’Arbonne Lake during both spring and fall
samplings. The substantial increases in yield in each assay
with the addition of phosphorus and the lack of response to the
addition of nitrogen indicate phosphorus limitation. In both
assays the simultaneous addition of nitrogen and phosphorus re-
sulted in maximum yield.
The N/P ratio in the field was 7/1 in the spring and 5/1
in the fall suggesting nitrogen limitation. The N/P ratio was
47/1 in the summer indicating phosphorus limitation (a ratio of
-------
11
14/1 or greater suggests phosphorus limitation). Algal forms
generally 11 favored” by low N/P ratios, e.g. Dactylococcopsis
and Raphidiopsis , appeared during the spring and/or fall
sampling.
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 Louisiana
National Guard collected monthly near-surface grab samples from
each of the tributary sites indicated on the map (page v), ex-
cept 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 a USGS computer program for
calculating stream loadings. Nutrient loads indicated for tribu-
taries are those measured minus known point source loads, if any.
Nutrient loadings for unsampled “minor tributaries and imme-
diate drainage” (“ZZ” of USGS) were estimated by using the mean
annual nutrient loads, in kg/km 2 /year, in Cypress Creek, Stowe
Creek, and Camp Creek at Stations B-l, C-i, and F-i, respectively,
and multiplying the means by the ZZ area in km 2 .
The operator of the Ruston (North) wastewater treatment plant
provided monthly effluent samples and corresponding flow data. The
operators of the Bernice, Junction City, Dubach (South), Dubach
-------
13
(West), and Farmervil’Ie wastewater treatment plants provided
monthly effluent samples. Nutrient loads for those plants were
calculated using an estimated (per capita) flow and the provided
sample chemistries. Nutrient loads for the city of Ruston (South)
wastewater treatment plant were estimated at 1.134 kg P and
3.401 kg N/capita/year.

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 “o1igotrophic ’ 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.
