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 [ 3l4(a,b)],
and water quality monitoring [ lO6 and §305(b)] activities mandated
by the Federal Water Pollution Cor trol 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 Wis-
consin National Guard for conduct of the tributary sampling
phase of the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate Altoona Lake is eutrophic. Records of
others support this conclusion.
B. Pate-Limitino Nutrient:
Algal assay results indicate Altoona Lake was nitroaen limited
at the time the assay sample was collected. The lake data indicate
nitrogen limitation durinç the other sampling periods as well.
C. Nutrient Controllability:
1. Point sources--During the sampling year, Altoona Lake
received a total phosphorus load at a rate more than four times
the rate proposed by Vollenweider (in press) as “danqerous”; i.e.,
a eutrophic rate (see page 14). Of that load it is estimated that
point sources contributed less than 2%, and it is unlikely that
control of phosphorus at any or all of the point sources known to
be impacting Altoona Lake would result in any significant improve-
ment in the trophic condition of the lake.
2. Non-point sources (see page 14)--It is estimated that non-
point sources contributed over 98% of the total phosphorus load to
the lake. However, the phosphorus export of the Eau Claire River
was about twice that of unimpacted Wisconsin streams elsewhere and
-------

indicate underestimation of the point-source load. Nonetheless,
even if the Eau Claire River load was reduced to half the present
load, the loading rate to Altoona Lake would still be more than
twice the eutrophic rate.

:i. INTRODUCTION
Altoona Lake is an impoundment of the Eau Claire River in the lower
Chippewa River Drainage of northwest Wisconsin. The 27-foot dam was
constructed in 1939.
The primary uses of the lake are recreational. Swimming, boating,
and fishing are among these uses. Game fish present in the lake include
walleyes, largemouth bass, and panfish, but carp are reportedly a problem
(Sather and Threinen, 1964).
Although most of the shoreline is privately owned, public access is
provided. One resort provides services. Other uses of the lake are flood
control and low-flow augmentation.
About 80% of the drainage is in agricultural use, and most of the re-
mainder is wooded. The main agricultural uses are dairying and the pro-
duction of canning crops.

IV. LAKE WATER QUALITY SUMMARY
Altoona Lake was sampled three times at station 1 and twice at the
other three stations 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 the stations and from a number
of depths at each station (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 enum-
eration; and during the last visit, a single five-gallon depth-integrated
sample was composited from the four stations 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 25 feet at
station 1, 20 feet at station 2, 12 feet at station 3, and 20 feet at
station 4.
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 capri-
cornutum , indicates the potential primary productivity of
Altoona Lake was high at the time the sample was collected.
Also, the lack of response to increasing levels of orthophos-
phorus, until nitrogen was also added, indicates the lake was
nitrogen limited. Note that the addition of only nitrogen

resulted in a yield significantly greater than that of the
control
The lake data indicate nitrogen limitation during the
other sampling periods as well. Nitrogen to phosphorus ratios
were 10 to 1 or less; i.e., nitrogen limitation would be
expected.
D. Trophic Condition:
Survey data and the records of others indicate that Altoona
Lake is eutrophic. A former resident reports that heavy algal
blooms were common during the summer months and that odor problems
were associated with the blooms at times (McCrady, 1974). Wisconsin
records show that the lake has been chemically treated for algae
control nearly every year since 1961 (Lueschow, 1972).
Of the 46 Wisconsin lakes included in the Survey, 30 had less
mean total phosphorus, 32 had less mean inorganic nitrogen, 26
had less mean chlorophyll a, and 37 had greater mean Secchi disc
transparency.

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 vii), except for the high runoff
months of April and May, when two samples were o1lected, and the colder
months of the year when ice cover prevented sampling at site A-i. Samp-
ling 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 tributary
sites nearest the lake.
In this report, the Eau Claire River nutrient loads were determined
by using a modification of a U.S. Geological Survey computer program
for calculating stream loadings*. Because no unimpacted streams were
sampled in the Altoona Lake basin, nutrient loadincis for unsampled ‘minor
tributaries and immediate drainage” (“ZZ” of U.S.G.S.) were calculated
using the mean concentrations in unimpacted Paint Creek, tributary to
nearby Lake Wissota, and the mean ZZ flow.
The effluent of the Village of Fall Creek wastewater treatment plant
was not sampled during the Survey. Nutrient loads attributed to this
source are based on the estimated contributing population and annual per
capita contributions of 2.5 lbs of phosphorus and 7.5 lbs of nitrogen.

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 nor-
phornetry permitted. A mesotrophic rate would be considered one
between “dangerous” and “permissible”.
Total Phosphorus — Total NitroQen
Units Total Accumulated Total Accumulated
lbs/acr /yr 177.6 loss* 1,936.0 loss*
grams/rn /yr 19.91 - 217.0 -
Vol1e weider loading rates for phosphorus
(g/m /yr) based on mean depth and mean
hydraulic retention time of Altoona Lake:
“Dangerous” (eutrophic rate) 4.20
“Permissible” (oligotrophic rate) 2.10
* During the sampling year, there appeared to be a significant loss of both
nitrogen and phosphorus from Altoona Lake. This would not be expected
even with the very short retention time of five days. Neither the avail-
able information on Altoona Lake and the drainage nor the Survey data pro-
vide an explanation for this unlikely imbalance, but it is noted that the
mean concentrations of both phosphorus and nitrogen were higher at the
outlet sampling site than at the inlet site. This, too, would not be
expected.
