FOREWORD
The National Eutrophication Survey was initiated in 1972 in
response to an Administration coninitment 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 { 3O3(e)J, 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, h and Parks for professional
involvement, to the South Dakota Nat nal 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 Coninittee 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. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Richmond Lake is eutrophic. It
ranked fifteenth in overall trophic quality when the 31 South
Dakota lakes sampled in 1974 were compared using a combination
of six water quality parameters*. Sixteen lakes had less median
total phosphorus, 25 had less median dissolved orthophosphorus,
17 had less and two had the same median inorganic nitrogen, 12
had less mean chlorophyll a, and three had greater mean Secchi
disc transparency.
Survey limnologists noted emergent vegetation along the shore-
line at stations 1 and 3 in April and an algal bloom at all sta-
tions in September.
B. Rate—Limiting Nutrient:
The algal assay results indicate that Richmond Lake was limited
by nitrogen at the time the sample was taken (09/18/74). The lake
data indicate nitrogen limitation at all sampling stations and times.
C. Nutrient Controllability:
1. Point sources--Septic tanks serving lakeshore dwellings and
two recreation areas contributed an estimated 8% of the total phos-
phorus load to Richmond Lake during the sampling year. However, a
* See Appendix A.

shoreline survey would have to be done to determine the actual
significance of those sources.
In addition, the Leola municipal wastewater treatment pond
discharges intermittently to Foot Creek about 45 kilometers
upstream. The treatment facility was not sampled, and the sig-
nificance of this source is not known. However, the phosphorus
export rate of Foot Creek was very low (see below) which indicates
the Leola discharge had a minimal impact during the sampling year.
The present phosphorus loading of 0.11 g/m 2 /year is 1.8 times
that proposed by Vollenweider (Vollenweider and Dillon, 1974) as
a eutrophic loading (see page 11). In view of the extremely long
mean hydraulic retention time (54 years), point-source phosphorus
reduction alone probably would not result in a significant improve-
ment in the trophic condition of the lake.
2. Non-point sources--Non-point sources contributed 92% of the
total phosphorus input during the sampling year. Foot Creek con-
tributed 42.7%, and the ungaged minor tributaries and immediate
drainage contributed an estimated 33.3%.
The phosphorus export rate of Foot Creek was less than 0.5 kg!
km 2 /yr (see page 10).

III. LAKE WATER QUALITY SUMMARY
Ricliiiond Lake 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 (4.6 m or near bottom to
surface) sample was composited from the stations for phytoplankton
identification 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 6.1 meters at station 1, 3.4 meters at station 2, and 1.5 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, Selenastrum capri-
cornutum , indicates that the potential primary productivity
of Richmond Lake was high at the time the sample was collected
(09/18/74). Also, the lack of growth response with the addition
of phosphorus alone until nitrogen was also added indicates
that the lake was limited by nitrogen at that time. Note
that the addition of only nitrogen resulted in a yield sig-
nificantly greater than that of the control.
The lake data also indicate nitrogen limitation; i.e.,
the mean inorganic nitrogen to orthophosphorus ratios were
2 to 1 or less at all sampling stations and times, and nitro-
gen limitation would be expected.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the South Dakota
National Guard collected monthly near-surface grab samples from
each of the tributary sites indicated on the map (page v). Sampling
was begun in October, 1974, and was completed in September, 1975.
Through an interagency agreement, stream flow estimates for the
year of sampling and a “normalized” or average year were provided by
the South Dakota District Office of the U.S. Geological Survey for the
tributary sites nearest the lake.
In this report, i’utrient loads for sampled tributaries were
calculated using mean annual concentrations and mean annual flows.
Nutrient loads for unsampled “minor tributaries and immediate
drainage” (“ZZ” of U.S.G.S.) were estimated using the mean concentra-
tions in Foot Creek at station A-2 and the mean annual ZZ flow.
The Leola wastewater treatment plant was not sampled and since
discharges to Foot Creek would be intermittent, estimates of nutrient
loads were not made.

F. Yearly Loads:
In the following table, the existing phosphorus loadings
are compared to those proposed by Vollenweider (Vollenweider
and Dillon, 1974). Essentially, his “dangerous” loading is
one at which the receiving water would become eutrophic or
remain eutrophic; his “permissible” loading is that which
would result in the receiving water remaining oligotrophic
or becoming oligotrophic if morphometry permitted. A meso-
trophic loading would be considered one between “dangerous”
and “permissible”.
Note that Vollenweider’s model may not be applicable to
water bodies with short hydraulic retention times.
