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 fresh water lakes and
reservoirs.
OBJECTIVES
The Survey was designed to develop, in conjunction with state
environmental agencies, information on nutrient sources, concentrations,
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 non-point
source pollution abatement in lake watersheds.
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 water-
shed 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 [ g3l4(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 condi-
tion are being made to advance the rationale and data base for
refinement of nutrient water quality criteria for the Nation’s
fresh water lakes. Likewise, multivarjate 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 EPA
and to augment plans implementation by the states.
ACKNOWLEDGMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Wisconsin Department of
Natural Resources for professional involvement and to the Wis-
consin National Guard for conduct of the tributary sampling
phase of the Survey.
Francis H. Schraufnagel, Acting Assistant Director, and Joseph
R. Ball of the Bureau of Water Quality, and Donald R. Winter, Lake
Rehabilitation Program, provided invaluable lake documentation and
counsel during the Survey. Central Office and District Office per-
sonnel of the Department of Natural Resources reviewed the prelim-
inary reports and provided critiques most useful in the preparation
of this Working Paper series.
Major General James J. Lison, Jr., the Adjutant General of
Wisconsin, and Project Officer CW-4 Donald D. Erickson, who directed
the volunteer efforts of the Wisconsin National Guardsmen, are also
gratefully acknowledged for their assistance to the Survey.

BIG EAU PLEINE RESERVOIR
STORET NO. 5565
I. CONCLUSIONS
A 0 Trophic Condition:
Survey data and the records of others indicate the Big Eau
Pleine Reservoir is eutrophic.
B. Rate—Limiting Nutrient:
The results of the algal assay indicate borderline nitrogen
limitation. However, the Reservoir data indicate phosphorus
limitation at station 1 on all sampling dates, while station 2
was phosphorus limited only in June and nitrogen limited in August
and November.
C. Nutrient Controllability:
1. Point sources——During the sampling year, the Big Eau
Pleine Reservoir received a phosphorus load at a rate over twice
that proposed by Vollenweider (in press) as “dangerous”; i.e.,
a eutrophic rate (see page 15). Of this load, it is estimated
that the Village of Stratford contributed less than 3%, and it
is concluded that phosphorus control at this source alone would
not result in a significant improvement in the trophic condition
of the reservoir.
2. Non—point sources——The phosphorus export of the Big Eau
Pleine River during the sampling year was more than twice that
of Fenwood Creek and nearly six times that of Freeman Creek (see
-------
2
page 15). If it is reasonable to assume that the phosphorus
export of Fenwood Creek, not known to be impacted by point
sources, represents typical areal or non-point source contri-
butions of the drainage, then it appears that municipal and
possibly industrial point sources tributary to the Big Eau
Pleine River, but not included in the Survey, were contributing
significant amounts of phosphorus during the sampling year.

II. INTRODUCTION
The Big Eau Pleine Reservoir was created by impoundment of the Big
Eau Pleine River by the Wisconsin Valley Improvement Company in 1937
(Martin and Hanson, 1966). The primary use of the reservoir is flow
augmentation for the hydroelectric plant downstream on Lake DuBay.
Recreational uses of the reservoir include swimming, boating, and
fishing. Game fish said to be present are muskellunge, northern pike,
walleyes, largemouth bass, and panfish (Anonymous, 1972).
Though much of land around the reservoir is owned and controlled by
the Wisconsin Valley Improvement Company, there are privately owned cot-
tages and permanent homes on the shoreline, and public access is provided
(Gall, 1972).

IV. LAKE WATER QUALITY SUMMARY
The Big Eau Pleine Reservoir was sampled three times during the
open-water season of 1972 by means of a pontoon—equipped Huey helicopter.
Each time, samples for physical and chemical parameters were collected
from two stations on the lake and from a number of depths at each station
(see map, page vi). During each visit, a single depth—integrated (15
feet to surface) sample was composited from the stations for phytoplankton
identification and enumeration; and during the last visit, a single five—
gallon depth—integrated sample was composited for algal assays. Also each
time, a depth-integrated sample was collected from each of the stations
for chlorophyll a analysis. The maximum depths sampled were 36 feet at
station 1 and 20 feet at station 2.
The results obtained are presented in full in Appendix B, and the
data for the fall sampling period, when the lake was essentially well—
mixed, are summarized below. Note, however, the Secchi disc summary
is based on all values.
For differences in the various parameters at the other sampling
times, refer to Appendix B.

The yield responses to the orthophosphorus spikes were
somewhat erratic, but the increased yields resulting from
the addition of nitrogen alone and in combination with ortho-
phosphorus indicates some nitrogen limitation in the assay
sample. The sample N/P ratio was a borderline 13/1.
The mean reservoir data indicate a borderline nitrogen
limitation at the time the sample was collected; however, at
the same time, the mean N/P ratio at station 1 was 17/1 and
at station 2 was 11/1 (i.e., phosphorus limitation would be
expected at station 1, and nitrogen limitation would be ex-
pected at station 2). The reservoir data also indicate
phosphorus limitation at station 1 at the other two samp-
ling times as well, but station 2 is indicated to have been
phosphorus limited in June and nitrogen limited again in
August.
Survey data do not provide an explanation for these unusual
circumstances, but the hydraulics of the reservoir and the
proximity of station 2 to Freeman Creek may be involved.
D. Trophic Condition:
Survey data and the reports of others (Schmidt, et al., 1972)
show that the Big Eau Pleine Reservoir is eutrophic. Reportedly,
rooted aquatic vegetation is essentially non—existent because of
-------
10
fluctuating water levels, but algal blooms are common. Survey
limnologists noted a heavy algal bloom in June, 1972.
Of the 46 Wisconsin lakes studied, 22 had less mean total phos-
phorus, 37 had less mean inorganic nitrogen, 30 had greater
Secchi disc transparency, 35 had less mean chlorophyll a, and 36
had less algal assay control yield.
Marked depression of dissolved oxygen was noted at both samp-
ling stations during the August, 1972 sampling.

V. NUTRIENT LOADINGS
(See Appendix C for data)
For the determination of nutrient loadings, the Wisconsin National
Guard collected monthly near—surface grab samples from each of the tribu-
tary sites indicated on the map (page vi), except for the high runoff months
of April and May when two samples were collected. Sampling was begun in
September, 1972, and was completed in August, 1973.
Through an interagency agreement, stream flow estimates for the year
of sampling and a “normalized” or average year were provided by the Wis-
consin District Office of the U.S. Geological Survey for the tributary
sites nearest the lake.
In this report, nutrient loads for sampled tributaries were determined
by using a modification of a U.S. Geological Survey computer program for
calculating stream loadings. Nutrient loads for unsampled “minor tribu-
taries and immediate drainage” (“ZZ” of U.S.G.S) were determined by using
the means of the loads, in lbs/mi 2 /year, calculated for stations B—i and
C—l and multiplying the means by the ZZ area in square miles.
The Village of Stratford declined participation in the Survey and
nutrient loads from there were estimated at 2.5 lbs P and 7.5 lbs NI
capita/year 0 In the following loading and export tables, the loads at-
tributed to the Big Eau Pieine River do not include the Stratford loads.
The communities of Abbotsford, Colby, and Stetsonville were outside
of the 25-mile limit of the Survey, and industries in the drainage basin
were excluded because of the constraints of the Survey. However, it
-------
12
appears these sources may have had an impact on the Big Eau Pleine Reservoir
during the sampling year (see discussion, page 2).

2 Industrial —
Reportedly (McKersie, et al., 1970), in the Big Eau Pleine
drainage basin there are nine cheese plants, a whey—drying
plant, a milk—processing plant, a rendering plant, and a mink
farm, all having individual waste treatment facilities. When
last surveyed by the Wisconsin Department of Natural Resources
in 1969—70, the waste treatment of three of the cheese plants
was considered unsatisfactory. However, the treatment facilities
and/or practices were improved and are adequate at this time
(Schraufnagel, 1974).

* There was an apparent loss of nitrogen during the sampling year. This
may have been due to nitrogen fixation in the Reservoir, solubilization
of previously sedimented nitrogen, recharge with nitrogen-rich ground
water, or (probably) the seasonal drawdown of the Reservoir for power
production at downstream Lake DuBoy.
