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)], water
quality criteria/standards review [§303(c)], clean lakes [§314(a,b)j,
and water quality monitoring [§106 and §305(b)] activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.
-------
iii
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.

LAKE HERMAN
STORET NO. 4612
I. INTRODUCTION
Due to lack of flows, only a few tributary samples 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 Herman is eutrophic. It
ranked twenty-fifth in overall trophic quality when the 31
South Dakota lakes sampled in 1974 were compared using a com-
bination of six water quality parameters*. Twenty-five of the
lakes had less median total phosphorus, 27 had less median dis-
solved orthophosphorus, 20 had less median inorganic nitrogen,
20 had less mean chlorophyll a^, and 22 had less mean Secchi disc
transparency."
Survey limnologists noted a heavy algal bloom and extensive
beds of submerged macrophytes in July, and this reportedly is an
annual occurrence (Churchill et al., 1975).
B. Rate-Limiting Nutrient:
The algal assay results indicate that the lake was nitrogen
limited in April. The lake data indicate nitrogen limitation at
all sampling times.

IV. LAKE WATER QUALITY SUMMARY
Lake Herman 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 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 and 1.2 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 Herman was high at the time the sample was collected
(04/23/74). Also, the significant increase in yield with the
addition of nitrogen alone indicates that the lake was limited
by nitrogen at that time. Note that the addition of phosphorus
alone did not result in an increased yield.
The lake data also indicate nitrogen limitation; i.e.,
the mean inorganic nitrogen/orthophosphorus ratios were 3/1
or less at all sampling times.
