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 [§303(e)J, water
quality criteria/standards review [§303(c)], clean lakes [§314(a,b)],
and water quality monitoring [§106 and §305(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
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 Blaine 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 lack of flows, only a few tributary samples were collected,
and no outlet samples were taken. Therefore, this report relates only
to the lake sampling data. However, the few tributary sampling data
obtained are included in Appendix D for the record.
II. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Byron is eutrophic. It
ranked thirtieth in overall trophic quality when the 31 South
Dakota lakes sampled in 1974 were compared using a combination
of six water quality parameters*. Twenty-seven of the lakes had
less median total phosphorus, 26 had less median dissolved ortho-
phosphorus, 29 had less median inorganic nitrogen, 28 had less
mean chlorophyll a_, and 25 had greater mean Secchi disc trans-
parency.
Survey limnologists noted that the lake was very turbid and
observed algal blooms in July and September.
B. Rate-Limiting Nutrient:
The algal assay results indicate that the lake was limited by
nitrogen at the time the sample was collected (09/18/74). The
lake data indicate nitrogen limitation at all sampling stations
and times.

IV. LAKE WATER QUALITY SUMMARY
Lake Byron 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
one or more depths at two 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 ide.otifica-
tion and enumeration; and during the last 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 0.6 meters
at station 1 and 0.9 meters at station 2.
The sampling results are presented in full in Appendix C and are
summarized in the following table.

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum, indicates that the potential primary productivity
of Lake Byron was very high at the time the sample was col-
lected (09/18/74). Also, the significant increase in yield
with the addition of nitrogen alone indicates that the lake
was limited by nitrogen at that time. Mote that the addition
of phosphorus alone did not result in an increased yield.
The lake data also indicate nitrogen limitation. The
mean inorganic nitrogen/orthophosphorus ratios were 3/1 or
less at all sampling times.
