FOREWORD
The National Eutrophication Survey was initiated in 1972 in
response to an Administration comitment 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 [ 5303(e)], water
quality criteria/standards review [ 5303(c)], clean lakes [ 5314(a,b)],
and water quality monitoring [ 5106 and 5305(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 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 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.

NAGAWICKA LAKE
STORET NO. 5531
I. CONCLUSIONS
A. Trophic Condition:
Survey data and the records of others show that Nagawicka
Lake is eutrophic.
B. Rate—Limiting Nutrient:
Algal assay results are not indicative of the rate-limiting
nutrient because of a significant loss of phosphorus in the sam-
ple. The lake data indicate nitrogen limitation at all sampling
times.
C. Nutrient Controllability:
1. Point sources——During the sampling year, Nagawicka Lake
received a total phosphorus load at a rate well in excess of that
proposed by Vollenweider (in press) as hldangerousu; i.e., a eu-
trophic rate (see page 15). It is estimated that the Village of
Hartland contributed just over 56% of this load. This estimate
may be too conservative; the P load in the Bark River at A—3,
below the STP, minus the load at A—2, above the SIP, is nearly
7,500 ibs, or 61% of the total phosphorus load for the sampling
year. Also, using limited nutrient and flow data obtained in
1969 by the Wisconsin Department of Natural Resources (McKersie,
et al,, 1971), it is calculated that Hartland was discharging
about 8,000 lbs of phosphorus per year at that time.
-------
2
However, considering only the conservative estimate, the total
phosphorus loading rates that can be achieved by specified levels
of phosphorus removal at the Hartland SIP, as compared to
Vollenweider’s suggested rates, are:
Total P Loading Rate
% P Removal lbs/acre/yr g/m 2 /yr
Existing 11.9 1.33
50 8.5 0.95
70 7.1 0.80
80 6 5 0.72
90 6.8 0.65
100 5.1 0.57
Vollenweider:
“Dangerous” (eutrophic rate) 0.50
“Permissible” (oligotrophic rate) 0.25
None of the removal options would result in a loading rate
less than “dangerous”, assuming the load estimated for Hartland
is correct. However, if the load indicated by the difference in
stream loads (i.e., 7,500 ibs) is more accurate, 100% removal
would result in a loading rate of 4.5 lbs/acre/yr or 0.50 g/
m 2 /yr.
Presently, the Village of Hartland is proposing a connection
to new treatment facilities to be constructed at the City of
Delafield with effluent discharge to the Bark River below Naga—
wicka Lake. It appears that this action would result in at least
-------
some improvement of the trophic condition of the lake after a
new nutrient equilibrium becomes established.
2. Non-point sources (see page 15)—-The estimated phosphorus
export of the Bark River during the sampling year was appreciably
higher than that calculated for unimpacted Otter Creek (74 Ibs/
2
mi /yr), tributary to Lake Koshkonong elsewhere in the Rock River
drainage. Considering that the Bark River was sampled near the
headwaters, the higher export probably resulted from underestima-
tion of the point-source load.

II. INTRODUCTION
Nagawicka Lake is located in the upper portion of the Bark River
subdrainage in the lower Rock River drainage in the glaciated south-
eastern part of Wisconsin. Land use in the drainage is predominately
agricultural.
The primary uses of the lake are recreational; these include swim-
ming, boating, and fishing. Game fish present are northern pike, wall—
eyes, large— and smailmouth bass, and panfish. Reportedly, fishing is
good, but weeds constitute a major use problem (Poff and Threinen, 1963).
Much of the shoreline is privately owned, but public access is pro-
vided. The county park on the east side of the lake provides excellent
access for multiple uses. Commercial facilities are available.

IV. LAKE WATER QUALITY SUMMARY
Nagawicka Lake 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 station 1 (see map,
page vi). During each visit, a single depth-integrated (15 feet or
near bottom 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 75 feet at station 1 and 4 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 esentially 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

2. Discussion —
The control yield of the assay alga, Selenastrurn capri—
cornutum , indicates that the potential primary productivity
of Nagawicka Lake was quite high at the time the sample was
collected despite a loss of over half of the dissolved phos-
phorus (74 pg/i) between the time of sample collection and
the beginning of the assay.

The assay results indicate phosphorus limitation; however,
had the phosphorus loss not occurred, the sample would have
been nitrogen limited. The lake data indicate an N/P ratio
of 8/1 at the time the assay sample was collected; i.e.,
nitrogen limitation would be expected. The N/P ratios at the
other sampling times were 5/1 or less.
D. Trophic Condition:
Survey data and the records of others (Ketelle and Uttormark,
1971) show that Nagawicka Lake is eutrophic. Wisconsin Department
of Natural Resource records show that the lake has been chemically
treated for algae and weed control almost every year since 1950
(Lueschow, 1972), and Survey limnologists noted the occurrence of
heavy growths of aquatic vegetation, particularly in the northern
end of the lake.
Of the 46 Wisconsin lakes studied, 34 had less mean total phos-
phorus, 37 had less mean dissolved phosphorus, 40 had less mean
inorganic nitrogen, and only three lakes had a higher algal assay
control yield.
Marked depression of dissolved oxygen with depth was evident
at station 1 in June and August of 1972, and oxygen was depleted
near the bottom in November, 1972.

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 loadings for unsampled “minor tribu-
taries and immediate drainage” (“ZZ” of U.S.G.S.) were calculated using the
mean concentrations in the Bark River at station A-2 and the mean ZZ flow.
The Village of Hartland declined participation in the Survey, and nu-
trient loads were estimated at 2.5 lbs P and 7.5 lbs N/capita/year. The
loads attributed to the Bark River at station A—3 do not include the esti-
mated Hartland STP loads.

In the following table, the existing phosphorus loading
rates are compared to those proposed by Vollenwieder (in press).
Essentially, his “dangerous” rate is the rate at which the

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 consid-
ered one between “dangerous” and “permissible”.
