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)]»
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 Wyoming Department of Environ-
roental Quality for professional involvement, to the Wyoming National
Guard for conducting the tributary sampling phase of the Survey,
and to those Wyoming wastewater treatment plant operators who
voluntarily provided effluent samples.
The staff of the Water Quality Division 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.
Brigadier General Games L. Spence, The Adjutant General of
Wyomingt and Project Officer Colonel Donald L. Boyer, who directed
the volunteer efforts of the Wyoming National Guardsmen, are also
gratefully acknowledged for their assistance to the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Keyhole Reservoir is eutrophic.
It ranked eighth in overall trophic quality when the 14 Wyoming
lakes and reservoirs sampled in 1975 were compared using a
combination of six parameters*. Four of the waterbodies had
less median total phosphorus, three had less and one had the same
median dissolved orthophosphorus, five had less median inorganic
nitrogen, nine had less mean chlorophyll a_, and eight had
greater mean Secchi disc transparency. Depression of dissolved
oxygen with depth occurred at stations 1 and 3 in August.
Survey limnologists noted an algal bloom in the reser-
voir in October.
B. Rate-Limiting Nutrient:
Due to nutrient changes in the samples from the time of col-
lection to the beginning of the assays, the results are not con-
sidered representative of conditions in the reservoir at the
times of sampling (05/23/75 and 10/15/75).
The reservoir data indicate nitrogen limitation in May and
October and phosphorus limitation in August.
C. Nutrient Controllability:
1. Point sources—The City of Moorcroft contributed 7.2%
of the total phosphorus load to Keyhole Reservoir during the
* See Appendix A.
-------
2
sampling year. The septic tanks serving a lakeshore campground
were estimated to have added less than 0.1% of the total load.
The City of Gillette, located approximately 50 km upstream
from station A-2, discharged 13,670 kg of total phosphorus into
Donkey Creek during the sampling year. However, the impact of
this discharge was not evident at station A-2, possibly because
of less than normal precipitation and stream flow during the
year of sampling. It is probable that the phosphorus load of
Gillette impacts Keyhole Reservoir during years of normal
precipitation and higher runoff.
The present phosphorus loading of 0.46 g/m2/yr is more than
three times that proposed by Vollenweider (Vollenweider & Dillon,
1974) as a eutrophic loading (see page 11). Because of the
high loading and the long hydraulic retention time of the reser-
voir, all phosphorus inputs should be minimized as much as possible
to slow the aging of the reservoir.
2. Non-point sources--Non-point sources, including direct
precipitation, contributed 92.8% of the total phosphorus load
to the reservoir during the sampling year. The Belle Fourche
River added 48.1% of the total; Wind Creek, 29.7%; Mule Creek,
1.3%; and the ungaged tributaries contributed an estimated 9.9%.
The phosphorus export rates of the Belle Fourche River, Wind
Creek, and Mule Creek were 2, 22, and 7 kg/km2/yr, respectively
(see page 10). The higher rate of Wind Creek may be due to an
unknown point source or to insufficient sampling.

III. WATER QUALITY SUMMARY
Keyhole Reservoir was sampled three times during the open-water
season of 1975 by means of a pontoon-equipped Huey helicopter. Each
time, samples for physical and chemical parameters were collected from
two or more depths at four stations on the reservoir (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 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 15.5 meters at station 1, 10.4 meters at station 2, 14.6
meters at station 3, and 4.6 meters at station 4.
The sampling results are presented in full in Appendix D and are

C. Limiting Nutrient Study:
Due to significant nutrient changes in the samples from the
time of collection to the beginning of the assays, the results
are not considered representative of conditions in the reser-
voir at the times the samples were collected (05/23/75 and
10/15/75).
The reservoir data indicate nitrogen limitation in May and
October and phosphorus limitation in August. The mean inorganic
nitrogen to orthophosphorus ratios were 12 to 1 in May, 14 to 1
in August, and 13 to 1 in October.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Wyoming National
Guard collected monthly near-surface grab samples from each of the tri-
butary sites indicated on the map (page vi), except for the high runoff
month of May when two samples were collected. Sampling was begun in
October, 1974, and was completed in June, 1975.
Through an interagency agreement, stream flow estimates for the year
of sampling and a "normalized" or average year were provided by the Wyo-
ming District Office of the U.S. Geological Survey for the tributary
sites nearest the reservoir.
In this report, nutrient loads for sampled tributaries were cal-
culated using mean annual concentrations and mean annual flows. Nutrient
loads shown are those measured minus point-source loads, if any.
Nutrient loads for unsampled "minor tributaries and immediate drain-
age" ("ZZ" of U.S.G.S.) were estimated using the means of the concen-
trations in Wind Creek and Mule Creek at stations B-l and C-l and the
mean annual ZZ flow.
The operators of the Gillette and Moorcroft wastewater treatment
plants provided monthly effluent samples and corresponding flow data.

E. 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.
