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 Iowa Department of Environ-
mental Quality for professional involvement, to the Iowa National
Guard for conducting the tributary sampling phase of the Survey,
and to those wastewater treatment plant operators who voluntarily
provided effluent samples and flow data.
The staff of the Water Quality Division of the Department of
Environmental Quality 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 Joseph G. May, the Adjutant General of Iowa,
and Project Officer Colonel Cleadeth P. Woods, who directed the
volunteer efforts of the Iowa National Guardsmen, are also grate-
fully acknowledged for their assistance to the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Red Rock Reservoir is eutrophic.
It ranked thirteenth in overall trophic quality when the 15 Iowa
lakes and reservoirs sampled in 1974 were compared using a com-
bination of six parameters*. Twelve of the water bodies had less
median total phosphorus, all of the others had less median dis-
solved phosphorus, 12 had less median inorganic nitrogen, five
had less mean chlorophyll a_, and nine had greater mean Secchi disc
transparency. Marked depression of dissolved oxygen with depth
occurred at stations 1, 3, and 5 in July.
B. Rate-Limiting Nutrient:
The algal assay results indicate the reservoir was phosphorus
limited at the time the sample was collected (04/18/74). The
reservoir data indicate phosphorus limitation in September also.
C. Nutrient Controllability:
1. Point sources--The phosphorus contribution of known point
sources accounted for about 17% of the total load reaching Red
Rock Reservoir during the sampling year. Almost all of the point-
source load came from the Des Moines wastewater treatment plant
(16.4% of the total).
* See Appendix A.
-------
2
The present phosphorus loading of 68.95 g/m2/yr is more than
35 times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 14). However, Vollenweider's
model probably is not applicable to water bodies with short hydrau-
lic retention times, and the mean hydraulic retention time of Red
Rock Reservoir is only 10 days. Nonetheless, the existing trophic
condition of the reservoir is evidence of excessive nutrient loads.
On the basis of Survey data, the trophic condition of Red
Rock Reservoir will very likely continue to deteriorate if the
present loading is maintained. Therefore, all phosphorus inputs
should be minimized to the greatest practicable extent to reduce
the rate of eutrophication.
2. Non-point sources--Non-point sources accounted for about
83% of the total phosphorus load reaching the reservoir during
the sampling year. The Des Moines River contributed over 78% of
the total.
The phosphorus export rate of the Des Moines River was 65
kg/km2/yr (see page 13). This rate is within the range of other
tributaries studied in this area of the state and appears to
be typical of a heavily-cultivated watershed.
Fluctuations in the water level of the reservoir may add to
the non-point contributions. In July, 1974, the Survey limnologists
reported flooded farmland in the vicinity of Red Rock Reservoir.
During the April and September visits, however, lake sampling
sites 4, 5, and 6 were dry (see map, page v).
-------
3
The upper portion of Red Rock Reservoir is a wildlife refuge,
and ducks and geese utilize the area during spring and fall migra-
tions (Harrison, 1976). However, only a few waterfowl counts were
made during the Survey sampling year (Bishop, 1976), and an assess-
ment of the nutrient contributions of migrating ducks and geese
cannot be made.

III. LAKE WATER QUALITY SUMMARY
Red Rock Reservoir was sampled three times during the open-water
season of 1974 by means of a pontoon-equipped Huey helicopter. Samples
for physical and chemical parameters were collected from a number of
depths at two stations on the reservoir in April, five stations in July,
and three stations in September (see map, page v). During each visit,
a single depth-integrated (4.6 m or near bottom to surface) sample was
composited from the sampled stations for phytoplankton identification
and enumeration; and during the April visit, a single 18.9-liter depth"
integrated sample was composited for algal.assays. Also each time, a
depths-integrated sample was collected from each of the sampled stations
for chlorophyll a^ analysis. The maximum depths sampled were 18.9 meters
at station 1, 6.4 meters at station 2, 13.7 meters at station 3, 9.8
meters at station 4, 13.1 meters at station 5, and 4.6 meters at station
6.
The sampling results are presented in full in Appendix D and are
summarized in the following table (the July nutrient samples were not
preserved properly and were not analyzed).

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum, indicates that the potential primary productivity
of Red Rock Reservoir was high at the time the sample was
collected in April. The addition of phosphorus alone produced
a significant increase in yield, but no such increase occurred
when only nitrogen was added. This indicates limitation by
phosphorus.
The reservoir data also indicate phosphorus limitation. The
mean inorganic nitrogen to orthophosphorus ratios were 18 to
1 or greater in April and September.
-------
IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Iowa National
Guard collected monthly near-surface grab samples from each of the
tributary sites indicated on the map (page vi)s except for the high
runoff months of April and May when two samples were collected.
Sampling was begun in August, 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 Iowa District Office of the U.S. Geological Survey for the
tributary sites nearest the reservoir.
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 unsampled "minor tributaries and immediate
drainage" ("II" of U.S.G.S.) were estimated using the means of the
nutrient concentrations at stations E-l, F-l, G-l, and H-l and the
mean annual II flow.
The operator of the Des Moines wastewater treatment plant provided
monthly effluent samples and corresponding flow data. The operators
of the wastewater treatment plants of Carlisle9 Des Moines Highland
Hills, Indianola, Knoxville, Monroe, Pleasantville, and Prairie City
did not participate; nutrient loads from these sources were estimated
at 1.134 kg P and 3.401 kg N/capita/year, and flows were estimated at
0.3785 m3/capita/day.

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.
