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)j, 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.
-------
m
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
fresh water 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.
ACKNOWLEDGEMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U.S. Environmental. Protection Agency)
express sincere appreciation to the Montana Department of Health
and Environmental Sciences for professional involvement, to the
Montana National Guard for conducting the tributary sampling
phase of the Survey, and to those Montana wastewater treatment
plant operators who voluntarily provided effluent samples.
The staff of the Water Quality Bureau 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 John J. Womack, the Adjutant General of Montana,
and Project Officer Major William Yeager, who directed the volun-
teer efforts of the Montana National Guardsmen, are also gratefully
acknowledged for their assistance to the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Tongue River Reservoir is eutrophic.
It ranked fourteenth in overall trophic quality when the 15 Mon-
tana lakes and reservoirs sampled in 1975 were compared using a
combination of six water-quality parameters*. All of the other
water bodies had less median total phosphorus, eight had less
median dissolved orthophosphorus, five had less and three had the
same median inorganic nitrogen, and all of the others had less
mean chlorophyll a_ and greater mean Secchi disc transparency.
Marked depletion of dissolved oxygen with depth occurred at
station 1 in May.
B. Rate-Limiting Nutrient:
Due to significant changes in nutrient levels during shipment
of the samples 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 taken.
The reservoir data indicate nitrogen limitation at all sam-
pling stations and times, with the exception of station 1 in Octo-
ber.
C. Nutrient Controllability:
1. Point sources—The wastewater treatment plant at Sheridan,
* See Appendix A.
-------
2
Wyoming accounted for the entire point source load, contributing
11.1% of the total phosphorus input to Tongue River Reservoir
during the sampling year.
The present phosphorus loading of 9.44 g/m 2/year is nine
times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 11), and point-source phos-
phorus control alone probably would not result in any significant
improvement in the existing trophic condition of the reservoir.
2. Non-point sources—Non-point sources accounted for 88.9% of
the total phosphorus load during the sampling year. The Tongue
River contributed 75.4%, and ungaged minor tributaries and imme-
diate drainage contributed an estimated 13.3%.
In a previous report, it is noted that agriculture is the major
water use in the drainage basin (Polzin, 1974). Water is diverted
for the irrigation of about 260 km2above the reservoir (Anonymous,
1974). It appears that improvement in the trophic quality of this
water body could only result from control of nutrients in agricul-
tural runoff as well as in point-source discharges within the drain-
age. Further study is needed to determine the controllability of
non-point nutrients and to also determine the impact of mining
operations in the area which could further degrade the quality
of this water body.

III. WATER QUALITY SUMMARY
Tongue River 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 one or more depths at three 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
May and October 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 16.2 meters at station
1, 9.1 meters at station 2, and 5.8 meters at station 3.
The sampling results are presented in full in Appendix D and
are summarized in the following table.

C. Limiting Nutrient Study:
The algal assay results are not considered indicative of con-
ditions in the reservoir at the time the samples were collected
(05/23/75 and 10/15/75) due to significant changes in nutrient
levels during shipment of the samples from the field to the labora-
tory.
The reservoir data indicate nitrogen limitation at all sta-
tions and sampling times, with the exception of station 1 in
October; i.e., the mean inorganic nitrogen/orthophosphorus ratios
were 10/1 or less. However, the mean N/P ratio in October at sta-
tion 1 was 15/1, and phosphorus limitation would be expected.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Montana 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 September, 1975.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Montana 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" ("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 Sheridan 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.
