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 arid 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 [ 5303(c)], clean lakes [ 53l4(a,b)],
and water quality monitoring [ 5106 and 5305(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, 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.
Major General James J. Lison, Jr., the Adjutant (eneral 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.

STORET NO. 5509
I. CONCLUSIONS
A. Trophic Condition:
Survey data and the records of others indicate that Butternut
Lake is eutrophic.
B. Rate—Limiting Nutrient:
Algal assay results and lake data indicate that Butternut
Lake was nitrogen limited during the period of Survey sampling.
C. Nutrient Controllability:
1. Point sources--It is calculated that during the sampling
year, the total phosphorus load to Butternut Lake from all sources
just exceeded that proposed by Vollenweider (in press) as “danger-
ous”; i.e., a eutrophic rate (see page 14). Of that load, it is
estimated that the Village of Butternut contributed about 34%.
In the following table, the total phosphorus loading rates
that can be achieved by specified levels of phosphorus removal at
the Butternut treatment facilities are shown and compared to Vol-
lenweider’s suggested loading rates.

A final discharge permit has been issued to the Village of
Butternut by the Wisconsin Department of Natural Resources.
Included in the conditions of the permit is a requirement for
either 85% phosphorus removal or elimination of effluent dis-
charge to the lake.
It will be noted that either of these phosphorus removal
options will reduce the loading rate to less than the dangerous
or eutrophic rate and should at least result in a reduction of
the incidence and severity of nuisance algal blooms in Butternut
Lake. On the basis of Vollenweider’s models, a significant im-
provement in the trophic condition of the lake would be predicted.
2. Non-point sources (see page 14)--The phosphorus exports
of Butternut and Spiller creeks were similar to those of Wisconsin
streams studied elsewhere in the Chippewa River drainage.
In all, non-point sources are estimated to have contributed
about 60% of the total phosphorus load to Butternut Lake during
the sampling year.

II. INTRODUCTION
Butternut Lake is located in a sparsely populated area on the Ashland-
Price County line in northwestern Wisconsin. Topography in the watershed
is primarily rolling glacial terrain and is characterized by mixed conifers
and deciduous forest with limited farming activity except for dairying.
The primary uses of the lake are boating and fishing. Game fish present
include muskellunge, northern pike, walleyes, largemouth bass, and panfish;
commercial boating facilities are available, and public access is provided
(Anonymous, 1972).

IV. LAKE WATER QUALITY SUMIIARY
Butternut Lake was sampled three times during the open water season
of 1972 by means of a pontoon-equipped Huey helicopter. Except for the
first sampling period, samples for physical and chemical parameters were
collected from a number of depths at two sampling stations (see map, page
vi). During each visit, a single depth-integrated (near bottom to surface)
sample was composited from the two sites for phytoplankton identification
and enumeration; and during the last visit, a single five-gallon depth-
integrated sample was collected 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 10 feet at station 1 and 2C 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,

The control yield of the assay alga, Selenastrum capri-
cornutum , indicates the potential primary productivity of
Butternut Lake was moderate at the time the sampie was coi-
lected (about 55% of the Wisconsin iakes studied had lower
control yields). Also, the lack of significant change in
yields with increased levels of orthophosphorus, until nitro-
gen was also added, indicates the lake was nitrogen limited

at the time the sample was collected (note that the addition
of only nitrogen resulted in a yield significantly greater
than the control yield).
There was a 25% loss of inorganic nitrogen in the sample
between the time of collection and the beginning of the assay;
however, nitrogen limitation is also indicated by the lake data;
i.e., inorganic nitrogen to dissolved phosphorus ratios were
less than 8 to 1 on all occasions, and nitrogen limitation
would be expected.
D. Trophic Condition:
Survey data indicate Butternut Lake is eutrophic. Of the 44
Wisconsin lakes on which sampling was completed, 29 had less mean
total phosphorus, 31 had less mean dissolved phosphorus, 22 had
less mean inorganic nitrogen, and 22 had greater mean Secchi disc
transparencies.
Survey limnologists noted that Butternut Lake clarity varied
from “poor” to “very turbid,” and an algal bloom was observed in
June. Also, in a 1970 Department of Natural Resources report
(McKersie, et al., 1970), it is noted that Butternut Lake “...has
experienced heavy algae blooms”.
Butternut Lake is listed in “Problem Lakes in the United
States” (Ketelle and Uttormark, 1971).

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 calculated
using mean annual concentrations and mean annual flows. Nutrient loadings
for unsampled “minor tributaries and immediate drainage” (“ZZ” of U.S.G.S.)
were estimated by using the mean annual concentrations in Spiller Creek
at station B-l and the mean annual ZZ flow. In the nutrient loading tables
that follow, the loads attributed to Butternut Creek are those measured
at 44-1 minus the loads attributed to the Village of Butternut wastewater
treatment facility.
Since the Village of Butternut declined participation in the Survey,
nutrient loads from there were determined indirectly; i.e., the loads in
Butternut Creek at station A-l just below the treatment facility, minus
the loads in the creek at station A-3, just above the facility, equal
the loads from the facility.

E. Yearly Loading Rates:
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 mor-
phometry permitted. A mesotrophic rate would be considered one
between “dangerous” and “permissible”.
