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 freshwater 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 [ S303(e)], water
quality criteria/standards review [ 3O3(c)], clean lakes [ 3l4(a,b)],
and water quality monitoring [ 1O6 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
freshwater 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 South Dakota Departments of
Environmental Protection and Game, Fish and Parks for professional
involvement, to the South Dakota National Guard for conducting the
tributary sampling phase of the Survey, and to those wastewater
treatment plant operators who voluntarily provided effluent samples.
Allyn Lockner, Secretary, and Blame Barker and Duane Murphy,
Department of Environmental Quality; Douglas Hansen, Department
of Game, Fish and Parks; and James Hayden, Director, State Lakes
Preservation Committee provided invaluable lake documentation and
counsel during the Survey, reviewed the preliminary reports, and
provided critiques most useful in the preparation of this Working
Paper series.
Major General Duane L. Corning, the Adjutant General of South
Dakota, and Project Officer Colonel Robert D. Chalberg, who directed
the volunteer efforts of the South Dakota National Guardsmen, are also
gratefully acknowledged for their assistance to the Survey.

I. INTRODUCTION
Due to the lack of flows, only a few tributary samples were collected
at Lake Poinsett, and this report relates only to lake sampling data. The
few tributary data obtained are included in Appendix E for the record.
Lake Poinsett is the largest natural lake managed for fisheries in
South Dakota. It is of glacial origin and is situated in two extensive
glacial outwash aquifers. One to the northeast connects Lake Poinsett
to Dry Lake and the Big Sioux River, and another to the west connects Lake
Poinsett and Lake Albert. Land use in the lake drainage is predominantly
agricultural.
Lake Poinsett is used heavily for other recreational activities
besides fishing. These include boating, swimming, water-skiing, camping,
and picnicking. There are 467 lakeshore residences, most of which are
sumer homes. In addition, there are five resort areas located around
the lake and private y-owried campgrounds on the west side (Sharps and
Hanten, 1974).
II. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Poinsett is eutrophic. It
ranked nineteenth in overall trophic quality when the 31 South
Dakota lakes sampled in 1974 were compared using a combination
-------
2
of six water quality pararneters*. Thirteen of the lakes
had less median total phosphorus, 15 had less and one had the
same median dissolved orthophosphorus, 28 had less median inor-
ganic nitrogen, 17 had less mean chlorophyll a, and 17 had
greater mean Secchi disc transparency.
Survey limnologists noted that the shoreline at station 3
was fringed with submerged vegetation and observed an algal
bloom in progress in September.
Previous investigators of this lake have noted the advanced
degree of eutrophication present in the lake and attribute it to
the large annual nutrient load entering and retained in the lake
(Skille, 1971).
B. Rate-Limiting Nutrient:
The algal assay results indicate that Lake Poinsett was limi-
ted by phosphorus at the time the sample was collected (04/25/74).
The lake data indicate phosphorus limitation in April but nitrogen
limitation in iuly and September.

IV. LAKE WATER QUALITY SUMMARY
Lake Poinsett was sampled three times during the open—water season
of 1974 by means of a pontoon-equipped Huey helicopter. Each time,
samples for physical and chemical parameters were collected from two
or more depths at three stations on the lake (see map, page v). 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 first visit, a single 18.9—liter 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 2.1 meters at
station 1, 3.7 meters at station 2, and 3.0 meters at station 3.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

2. Discussion —
The control yield of the assay alga, Selenastruni capri-
cornutum , indicates that the potential primary productivity
of Lake Poinsett was moderate at the time the sample was col-
lected (04/25/74). Also, the significant increase in yield
with the addition of phosphorus alone indicates that the lake
was limited by phosphorus at that time. Note that the addi-
tion of nitrogen alone resulted in a yield not significantly
different from that of the control.
The lake data indicate phosphorus limitation in April
as well; i.e., the mean inorganic nitrogen to orthophosphorus
ratio was 20 to 1. However, nitrogen limitation is indicated
in July and September (the mean N to P ratios were 5 to 1 or
less, and nitrogen limitation would be expected).
