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 [ 3O3(e)], water
quality criteria/standards review [ 3O3(c)], clean lakes [ 3l4(a,b)],
and water quality monitoring [ lO6 and 3O5(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.
AC KNOWL EDGMENT
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 Connittee 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.

STOCKADE LAKE
STORET NO. 4628
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Stockade Lake is eutrophic. It
ranked twenty—third in overall trophic quality when the 31 South
Dakota lakes sampled in 1974 were compared using a combination
of six lake parameters*. Twenty—one of the lakes had less median
total phosphorus, 22 had less median dissolved orthophosphorus,
17 had less and two had the same median inorganic nitrogen, 15
had less mean chlorophyll a, and eight had greater mean Secchi
disc transparency. Marked depression or depletion of dissolved
oxygen with depth occurred in July and September at both sampling
stations.
Survey limnologists observed algal blooms in progress in July
and September.
B. Rate-Limiting Nutrient:
The algal assay results indicate that Stockade Lake was nitro-
gen limited at the times the samples were collected (04/24/74 and
09/11/74).
The lake data indicate nitrogen limitation at all sampling times.
C. Nutrient Controllability:
1. Point sources--Known point sources contributed 35.7% of
the total phosphorus load to Stockade Lake during the sampling

year. The City of Custer added 29.6% of the total phosphorus
load, and Sylvan Lake contributed 6.1%.
The present phosphorus loading of 1.25 g/m 2 /yr is 2.3 times
that proposed by Vollenweider (Vollenweider and Dillon, 1974) as
a eutrophic loading (see page 12).
On the basis of Survey data, even complete removal of phos-
phorus at the two point sources would still leave a loading nearly
1.5 times the eutrophic loading. However, the apparent marked
loss of both phosphorus and nitrogen during the year (see pages
10 and 11) indicates Survey sampling was not intensive enough to
determine the actual nutrient loadings.
2. Non—point sources--It is estimated that non-point sources
contributed 64.3% of the total phosphorus load reaching Stockade
Lake during the sampling year. French Creek added 54.5% of the
total, and the ungaged minor tributaries and immediate drainage
contributed an estimated 8.3%.

III. LAKE WATER QUALITY SUMMARY
Stockade 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 a number of depths at two 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
first and last visits, a sin ie 18.9-liter depth-integrated
sample was collected from each of the stations for chlorophyll a
analysis. The maximum depths sampled were 10.7 meters at station
1 and 5.2 meters at station 2.
The sampling results are presented in full in Appendix D and
are summarized in the following table.

2. Discussion -
The control yields of the assay alga, Selenastrum capri-
cornutum , indicate that the potential primary productivity
of Stockade Lake was high when the assay samples were taken
in April and September, 1974. The addition of nitrogen alone
resulted in significant increases in yield, but no such response
occurred with the addition of only phosphorus. Therefore, nitro-
gen limitation is indicated.
The lake data indicate nitrogen limitation at all sampling
times; i.e., the mean inorganic nitrogen to orthophosphorus
ratios were 1 to 1 in April and July and 2 to 1 in September.

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), except
for the high runoff months of April and May when two samples were
collected. Sampling was begun in October, 1974, and was completed
in July, 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, nutrient loads for sampled tributaries were
determined by using a modification of a U.S. Geological Survey computer
program for calculating stream loadings*. Nutrient loads shown are
those measured minus point-source loads, if any.
Nutrient loads for unsanipled “minor tributaries and imediate
drainage” (“ZZ” of U.S.G.S.) were estimated using the adjusted nutrient
loads at station A—2, in kg/km 2 /year, and multiplying by the ZZ area
in km 2 .
The operators of the Custer and Sylvan Lake wastewater treatment
plants provided monthly effluent samples and corresponding flow data.

F.
TTière was an apparent loss of nitrogen and phosphorus during the sampling
year. This may have been due to nitrogen fixation in the lake, solubili-
zation of previously sedimented phosphorus and nitrogen, recharge with
nutrient—rich ground water, unknown and unsampled point sources discharging
directly to the lake, or (probably) insufficier t tributary sampling.
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 mesa-
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.
