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 [ 3O3(e)], water
quality criteria/standards review [ 3O3(c)], clean lakes [ 53l4(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, 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 Minnesota Pollution Control
Agency for professional involvement and to the Minnesota National
Guard for conducting the tributary sampling phase of the Survey.
Grant J. Merritt, Director of the Minnesota Pollution Control
Agency, John F. McGuire, Chief, and Joel G. Schilling, Biologist,
of the Section of Surface and Groundwater, Division of Water Quality,
provided invaluable lake documentation and counsel during the course
of the Survey; and the staff of the Section of Municipal Works, Divi-
sion of Water Quality, were most helpful in identifying point sources
and soliciting municipal participation in the Survey.
Major General Chester J. Moeglein, the Adjutant General of
Minnesota, and Project Officer Major Adrian Beltrand, who directed
the volunteer efforts of the Minnesota National Guardsmen, are also
gratefully acknowledged for their assistance to the Survey.

LAKE PEPIN
STORET NO. 27A4
I. CONCLUSIONS
A. Trophic Condition:
Survey data show that Lake Pepin is eutrophic. Of the 60
Minnesota lakes sampled in the fall of 1972, when essentially
all were well-mixed, 42 had less mean total phosphorus, 43 had
less mean dissolved phosphorus, and 51 had less mean inorganic
nitrogen. Of all 80 Minnesota lakes sampled, 35 had less mean
chlorophyll a, and 42 had greater Secchi disc transparency.
Depression of dissolved oxygen with depth occurred at stations
1 and 2 in June, and low dissolved oxygen occurred at all stations
in September 1972.
B. Rate-Limiting Nutrient:
A significant loss of nutrients occurred in the algal assay
sample between the time of collection and the beginning of the
assay, and the results are not indicative of conditions in the
lake at the time of sampling. However, the lake data show
nitrogen limitation at all sampling times (N/P ratios were less
than 10/1 on all occasions).
C. Nutrient Controllability:
1. Point sources--During the sampling year, Lake Pepin
received a total phosphorus load at a rate nearly 11 times
the rate proposed by Vollenweider (in press) as “dangerous”;
-------
2
i.e., a eutrophic rate, see page 15). However, the mean
hydraulic retention time of Lake Pepln is quite short, and
Vollenweider’s model may not be applicable. Nonetheless,
the present trophic condition of the lake is indicative of
excessive nutrient loads.
It is calculated that complete removal of phosphorus
at the point sources considered in this study, including
the point sources impacting upstream Spring Lake* and Lake
St. Croix , would reduce the loading rate to about 21.6
g/m 2 /yr or about six times the eutrophic rate. A more
realistic phosphorus removal of 80% at the point sources
would reduce the loading rate to about 24.1 g/m 2 /yr or
about 7½ times the eutrophic rate. However, in view of
the questionable applicability of Vollenweider’s model to
Lake Pepin, it is believed that a high degree of point-
source phosphorus removal would improve the trophic condi-
tion of Lake Pepin, particularly if the high phosphorus
exports of the Lake Pepin tributaries (see below) can be
reduced by point or non-point phosphorus control.
2. Non-point sources (see page 14)--During the samp-
ling year, the phosphorus exports of all of the tributaries

to Lake Pepin were quite high. For example, the Mississippi
River, which had a mean non-point phosphorus export of about
77 lbs/m1 2 /yr at the outlet of Spring Lake, had a non-point
export of 102 lbs/mi 2 /yr at the inlet to Lake Pepin. Since
the mean non-point export of the St. Croix River near Prescott,
Wisconsin, was only 75 lbs/mi 2 /yr, it appears that unmeasured
point or non-point phosphorus sources between the Hastings,
Minnesota-Prescott, Wisconsin area and the inlet of Lake Pepin
contributed significantly to the Mississippi River export.
Likewise, the high phosphorus exports of the other tributaries,
ranging from 113 lbs to 216 lbs/mi 2 /yr, are indicative of un-
measured point or non-point source impacts.

III. LAKE WATER QUALITY SUMMARY
Lake Pepin 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 three stations
on the lake and usually 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 cornposited from the three 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 28 feet at station 1, 27 feet at station 2, and 19 feet at
station 3.
The results obtained are presented in full in Appendix B, and the
data for the fall sampling period, when the lake essentially was well-
mixed, are summarized below. Note, however, the Secchi disc summary
is based on all values.

C. Limiting Nutrient Study:
A significant loss of nutrients occurred in the algal assay
sample between the time of collection and the beginning of the
assay, and the results are not indicative of conditions in the
lake at the time of sampling. However, the lake data indicate
nitrogen limitation at all sampling times (N/P ratios were less
than 10/1 on all occasions).

IV. NUTRIENT LOADINGS
(See Appendix C for data)
For the determination of nutrient loadings, the Minnesota 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 March and May when two samples were collected. Sampling was
begun in October, 1972, and was completed in September, 1973.
Through an interagency agreement, stream flow estimates for the year
of sampling and a “normalized” or average year were provided by the Minne-
sota 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 ioadings*. 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 C—i,
H-i, J-1, and K—i and multiplying the means by the ZZ area in mi 2 .
The Chippewa River was sampled during the Survey, and nutrient loads
were determined. However, this river joins the Mississippi River down-
stream from the actual outlet of Lake Pepin but upstream from the Survey
outlet sampling station at A-i. Consequently, the Chippewa River nutrient
loads were subtracted from the loads measured at A-i to arrive at the
ee Working Paper No. 1.
-------
10
actual outlet loads. The nutrient loads given for the other tributaries
are those measured minus point sources, If any.
The operator of the Hastings wastewater treatment plant provided
monthly effluent samples and corresponding flow data. Nutrient loadings
for the cities of Red Wing, Lake City, and Cannon Falls, Minnesota, and
Pepin, Prescott, and Ellsworth, Wisconsin, were estimated at 2.5 lbs P
and 7.5 lbs N/capita/year.
The nutrient loads from the Ellsworth Creamery were not measured;
but, on the basis of comparable flows, the phosphorus load from the
Creamery was estimated to be the same as the Ellsworth waste treatment
plant load. However, nitrogen loads in dairy processing wastes are
usually about 1.4 times the phosphorus loads (Boydston, 1973), and the
Creamery nitrogen loads were estimated on that basis.
In the following loading tables, the point-source loads given for
Spring Lake point sources (above Hastings, MN) are those measured in
the Spring Lake study* adjusted for the calculated retention in that
lake (3% for phosphorus, none for nitrogen). The point source loads
given for Lake St. Croix point sources (above Prescott, WI) are those
measured in the St. Croix Lake study** adjusted for the calculated
retention in that lake (33% for phosphorus, <2% for 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 oligo-
trophic if morphometry permitted. A mesotrophic rate would
be considered one between “dangerous” and “permissible”.
Note that Vollenweider’s model may not be applicable to
water bodies with very short hydraulic retention times.
Total Phosphorus Total Nitrogen
Units Total Accumulated Total Accumulated
lbs/acre/yr 306.8 34.7 4,183.0 loss*
grams/mr/yr 34.39 3.89 468.8 -
Vollenweider loading rates for phosphorus
(g/m 2 /yr) based on mean depth and mean
hydraulic retention time of Lake Pepin:
“Dangerous” (eutrophic rate) 3.20
“Permissible” (oligotrophic rate) 1.60
* There was an apparent loss of nitrogen during the sampling year. This
may have been due to nitrogen fixation in the lake, solubilization of
previously sedimented nitrogen, recharge with nitrogen-rich ground water,
unknown and unsampled point sources discharging directly to the lake, or
underestimation of the nitrogen loads from the unmeasured municipal
sources. Whatever the cause, similar nitrogen loss has occurred at
Shagawa Lake which has been intensively studied by EPA’s National Eutro-
phication Research and Lake Restoration Branch.
