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.
-------
Ill
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-
mental 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 l
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 James L. Spence, The Adjutant General of
Wyoming, 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 Woodruff Narrows Reservoir is
eutrophic. It ranked last in overall trophic quality when the
14 Wyoming lakes and reservoirs sampled in 1975 were compared
using a combination of six parameters*. Twelve of the water
bodies had less median total phosphorus, 11 had less median
dissolved orthophosphorus, seven had less median inorganic
nitrogen, 12 had less mean chlorophyll a^, and 11 had greater
mean Secchi disc transparency. Marked depression of dissolved
oxygen with depth occurred at station 1 in August.
B. Rate-Limi ting Nutrient:
Because of significant nutrient changes in the samples dur-
ing shipment from the field to the laboratory, the algal assay
results are not considered representative of conditions in the
reservoir at the times the samples were collected (09/18/75 and
10/16/75).
The reservoir data indicate nitrogen limitation all four sam-
pling times.
C. Nutrient Controllability:
1. Point sources—The City of Evanston was the only known
point source contributing phosphorus to the reservoir during the
sampling year and added 15.7% of the total phosphorus load.
* See Appendix A.
-------
The present phosphorus loading of 6.02 g/mz/yr is more
than five times that proposed by Vollenweider (Vollenweider and
Dillon, 1974) as a eutrophic load (see page 12). Because of
this, the phosphorus inputs of all sources, point and non-point,
would have to be minimized to the greatest possible extent to
result in a significant improvement in the trophic condition
of the reservoir.
1. Non-point sources--Non-point sources, including direct
precipitation, contributed 84.3% of the total phosphorus load
to the reservoir during the sampling year. The Bear River added
80.8% of the total, and the ungaged tributaries contributed an
estimated 3.2%.
The phosphorus export rate of the Bear River was 18 kg/km2/yr
(see page 11). This rate is considerably higher than the rate of
Hams Fork, the major tributary of nearby Viva Naughton Reservoir*
(7 kg/km2/yr).

III. WATER QUALITY SUMMARY
Woodruff Narrows Reservoir was sampled four 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
a number of depths at two stations on the reservoir (see map, page v).
During each visit, a single depth-integrated (4.6 m to surface) sample
was composited from the stations for phytoplankton identification and
enumeration; and during the last two 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 9.4 meters at
station 1 and 7.3 meters at station 2.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

Limiting Nutrient Study:
Because of significant changes in nutrients in the samples
from the time of collection to the beginning of the assays, the
results are not considered representative of conditions in the
reservoir at the times the samples were taken (09/18/75 and
10/16/75).
The reservoir data indicate nitrogen limitation at all four
sampling times. The mean inorganic nitrogen to orthophosphorus
ratios were 3 to 1 in May, 7 to 1 in August, 5 to 1 in September,
and 6 to 1 in October; and nitrogen limitation would be expected.
-------
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
tributary sites indicated on the map (page v). Sampling was begun in
October, 1974, and was completed in April, 1975.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Wyoming District Office of the U.S. Geological Survey for the
tributary sites nearest the reservoir.
In this report, nutrient loads for sampled tributaries were deter-
mined by using a modification of a U.S. Geological Survey computer pro-
gram for calculating stream loadings*. 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 nutrient loads at
station A-2, in kg/km2/year, and multiplying by the ZZ area in km2.
The operator of the Evanston wastewater treatment plant provided
monthly effluent samples and corresponding flow data.

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.
