FOREWO RD
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 [ 314(a,b)],
and water quality monitoring [ lO6 and §305(b)] activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.
-------
iii
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, 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 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 Wisconsin
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.

I. CONCLUSIONS
A. Trophic Condition:
Survey data show that Lake Wausau is eutrophic.
B. Rate-Limiting Nutrient:
The algal assay results indicate that phosphorus was
limiting at the time the sample was collected in November,
1972. However, the lake data indicate nitrogen limitation
at the other sampling times.
C. Nutrient Controllability:
During the sampling year, there was an unexpected loss
of both phosphorus and nitrogen from Lake Wausau; i.e., about
39% more phosphorus (308,000 ibs) and 23% more nitrogen (2,150,-
000 ibs) were measured leaving the lake at the outlet station
(A-i; see map, page vi) than can be accounted for by all
measured and estimated inputs.
The cause of this marked nutrient imbalance is not known,
but it is unlikely that a nutrient wash-out occurred or that
a direct-discharge point-source of that magnitude was overlooked.
Also, there is no indication that there was any unusual operation
of the Rothschild dam such that flushing could have occurred
during the sampling year (Schraufnagel, 1974).
Considering the input phosphorus loads only, it does not
appear that phosphorus control at the point sources included in

the Survey would result in a significant improvement of the
trophic condition of Lake Wausau. However, the nutrient
imbalance noted above points to a need for a more detailed
study before an assessment of effect of phosphorus control
is made.

II. INTRODUCTION
Lake Wausau is an impoundment of the upper Wisconsin River at the
Village of Rothschild. According to the Wisconsin Department of Natural
Resources (Anonymous, 1972), Lake Wausau supports a game-fish popula-
tion which includes muskellunge, northern pike, walleye, bass, and
panfish.

IV. LAKE WATER QUALITY SUMMARY
Lake Wausau 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 usually from a number of depths at each station (see map,
page vii). During each visit, a single depth-integrated (near bottom
to surface) sample was composited from the stations for phytoplankton
identification and enumeration; and during the last visit, a 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 15 feet at sta-
tion 1 and 5 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.

2. Discussion —
The control yield of the assay alga, Selenastrum
capricornutum , indicates that the primary productivity
of the lake was high at the time the sample was collected
(22 of the 44 Wisconsin study lakes assayed had less
control yield). Also, the increase in yields with in-
creasing increments of orthophosphorus, and the lack of
growth response when only nitrogen was added, show that
Lake Wausau was phosphorus limited at that time. However,
the lake data indicate nitrogen limitation at the other
sampling times; N/P ratios were 7/1 in June and 9/1 in
August, and nitrogen limitation would be expected.
D. Trophic Condition:
Survey data indicate that Lake Wausau is eutrophic. Of
the 46 Wisconsin lakes studied, 20 had less mean total phos-
phorus, 25 had less mean dissolved phosphorus, and 29 had less
mean inorganic nitrogen.
Only seven of the study lakes had less mean chlorophyll a,
but 35 of the lakes had greater mean Secchi disc transparency.
The Survey limnologists noted that the lake was very turbid
and humic colored on all sampling occasions, and the relatively
low chlorophyll a concentrations may have been due to light
limitation.

V. NUTRIENT LOADINGS
(See Appendix C for data)
For the determination of nutrient loadings, the Wisconsin National
Guard collected a monthly near-surface grab sample 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
Wisconsin District Office of the U.S. Geological Survey for the tribu-
tary 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 loadings for unsampled “minor
tributaries and immediate drainage” (“ZZ” of U.S.G.S.) were estimated
by using the means of the nutrient loads, in lbs/mi 2 /year, at stations
A-2, B-i, 0—1, and E-l and multiplying by the ZZ area in mi 2 .
The operators of the Wausau, Brokaw, and Marathon wastewater treatment
plants provided monthly effluent samples and corresponding flow data from
which nutrient loads were calculated. However, the Village of Edgar and
the cities of Antigo and Merrill did not participate in the Survey, and
nutrient loads were estimated at 2.5 lbs P and 7.5 lbs N/capita/year.
In the following tables, the tributary loads shown are those measured
minus point—source loads, if any.

In the following table, the existing phosphorus loading
rates are compared to those proposed by Vollenweider (in press).
Essentially, his “dangerous” rate is the rate at which the
receiving waters would become eutrophic or remain eutrophic;
his “permissible” rate is that which would result in the
receiving water remaining oligotrophic or becoming oligotrophic
if morphometry permitted. A mesotrophic rate would be con-
sidered one between “dangerous” and “permissible”.
