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 imSact on selected freshwater lakes as a basis for formulating
comprehensive and coordinated national, regional, and state n^agement
prSi«s relating to point-source discharge reduction and non-point
source pollution abatement in lake watersheds.
ANALYTIC APPROACH
ThP mathematical and statistical procedures selected for the
Survey's eutroThication 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 rode!
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
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.

I. CONCLUSIONS
A. Trophic Condition:
Yellowtail Reservoir ranked seventh in overall trophic quality
among the 14 Wyoming lakes and reservoirs sampled in 1975 using a
combination of six water quality parameters*. However, Survey
data indicate this long water body (98 km) is mesotrophic at
stations 6 and 7; meso-eutrophic at station 5; and eutrophic at
stations 1, 2, 3, and 4.
At mesotrophic stations 6 and 7, spring and fall mean total
phosphorus ranged from 14 to 41 yg/1; spring and fall mean ortho-
phosphorus ranged from 6 to 31 yg/1; mean inorganic nitrogen
ranged from 240 to 600 yg/1; mean chlorophyll a_ ranged from 1.6
to 2.7 ijg/1; and mean Secchi disc transparency ranged from 2.4
to 15.2 meters.
At meso-eutrophic station 5, spring and fall mean total phos-
phorus ranged from 24 to 116 yg/1; mean orthophosphorus ranged
from 16 to 28 yg/1; mean inorganic nitrogen ranged from 280 to
810 yg/1; chlorophyll <* ranged from 1.3 to 4.4 yg/1; and Secchi
disc transparency ranged from 1.5 to 6.1 meters.
At eutrophic stations 1, 2, 3, and 4, spring and fall mean
total phosphorus ranged from 19 to 950 yg/1; mean orthophosphorus
ranged from 8 to 45 yg/1; mean inorganic nitrogen ranged from
* See Appendix A.
-------
2
260 to 670 vig/1; mean chlorophyll a_ ranged from 1.6 to 41.8
yg/1; and mean Secchi disc transparency ranged from 0.2 to 6.1
meters. No significant depression of dissolved oxygen occurred
at any of the sampling stations or times.
In a previous study, it was noted that a 60-fold increase in
turbidity and associated nitrate nitrogen and orthophosphate
occurred from the dam to the upper end of the reservoir; and
phytoplankton volumes also were noted to have increased similarly
(Wright and Soltero, 1973; Soltero, Wright, and Horpestad, 1973).
B. Rate-Limi ting Nutrient:
The algal assay results indicate Yellowtail Reservoir was
phosphorus limited at the time the sample was collected (10/17/75).
The reservoir data indicate phosphorus limitation at all sampling
stations and times, with the exception of stations 4 and 5 in
August.
C. Nutrient Controllability:
1. Point sources—The listed point sources accounted for 0.8%
of the total phosphorus input to the reservoir during the sampling
year. The wastewater treatment plants at Lovell, Byron, and Grey-
bull contributed 0.3%, 0.2%, and 0.1% of the total, respectively.
The Great Western Sugar Company at Lovell contributed 0.2%. In
addition, municipal wastewater facilities of unknown significance
-------
3
at Powell, Cody, Worland and Thermopolis discharge well upstream
in the Shoshone and Wind-Bighorn river drainages. Further investi-
gation is needed to determine the nutrient contributions of those
sources.
The present phosphorus loading of 20.42 g/m2/year is nearly 14
times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 15). Phosphorus loadings
of 33.40 g/m2/year and 15.23 g/m2/year derived from 1968 and 1969
phosphorus and flow data reported by Wright and Soltero (1973)
support Survey findings and indicate the need for nutrient control
to slow the present rate of eutrophication. However, it is cal-
culated that the present yearly load would have to be reduced by
nearly 93% to just equal the eutrophic loading. Such a reduction
would involve control of non-point as well as point-source phos-
phorus inputs.
2. Non-point sources--Non-point sources contributed 99.2% of
the total phosphorus load during the sampling year. The Bighorn
River contributed 64.1%, the Shoshone River contributed 32.9%,
Dry Head Creek contributed 0.1%, and Crooked Creek contributed
less than 0.1%. The ungaged minor tributaries and immediate
drainage contributed an estimated 2.0%.
The Bighorn and Shoshone rivers had phosphorus export rates
of 16 and 57 kg/km2/year, respectively. These rates are sub-
stantially higher than the rates of the other tributaries in the
-------
4
drainage basin (mean of 4 kg/km2/year; see page 14). This may
be indicative of significant inputs from the unsampled point
sources noted above or non-point sources. For the Bighorn River,
about 4.5% (30,360 kg/yr) of the load can be attributed to the
outflow of eutrophic Boysen Reservoir*; the remaining 95.5% was
contributed by runoff below the Boysen Dam and the Worland and
Thermopolis wastewater treatment facilities. In a previous study,
it is noted that increased flows in both rivers result in fer-
tilization of the reservoir with enriched suspended sediment (Sol-
tero, Wright, and Horpestad, 1973); and in another report, it is
stated that agricultural practices contribute an increased silt
load to the rivers from mid-April until late fall (Anonymous, 1974).
Further investigation is needed to determine the controllability of
such phosphorus inputs to the Bighorn and Shoshone rivers as well
as the significance of the unsampled point sources.

III. WATER QUALITY SUMMARY
Yellowtail Reservoir was sampled three times during the open-
water season of 1974 by means of a pontoon-equipped Huey helicopter.
Each times samples for physical and chemical parameters were collected
from one or more depths at seven 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 last
visit, a single 18., 9-liter depth-Integra ted sample was composited
from stations 1, 2, 3, and 4 for algal assays. Also each time, a
depth-integrated sample was collected from each of the stations for
chlorophyll ^analysis. The maximum depths sampled were 4.3 meters
at station 19 14.6 meters at station 2, 35.1 meters at station 3,
50.3 meters at station 4, 62.2 meters at station 5, 51.8 meters at
station 6S and 68.6 meters at station 7,

alga, Selenastrum capri-

of Yellowtail Reservoir was moderate at the time the sample
was collected (10/17/75). Also, a substantial increase in
yield with the addition of phosphorus alone indicates the
reservoir was phosphorus limited at that time. Note that
the addition of nitrogen alone resulted in a yield not sig-
nificantly greater than that of the control.
The reservoir data indicate phosphorus limitation as
-------

well; i.e., the mean inorganic nitrogen to orthophosphorus
ratios were 15 to 1 or greater at all sampling times, with
the exception of stations 4 and 5 in August (12 to 1 and 11
to 1, respectively). Phosphorus limitation is expected when
N/P ratios are greater than 13/1.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Wyoming and Montana
National Guard collected monthly near-surface grab samples from each of
the tributary sites indicated on the map (page y). 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 Wyoming and Montana District Offices 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" ("ZZ" of U.S.G.S.) were estimated using the nutrient loads
at station D-l, in kg/km2/year, and multiplying by the ZZ area in km2.
The operators of the Byron, Greybull, and Lovell wastewater treat-
ment plants provided monthly effluent samples and corresponding flow
data. The Great Western Sugar Company at Lovell, which discharges
untreated effluent, also provided monthly 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.
