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)j, clean lakes [§3l4(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
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 Koocanusa Reservoir is mesotrophic.
It ranked eleventh in overall trophic quality when the 15 Montana
lakes and reservoirs sampled in 1975 were compared using a com-
bination of six parameters*. Eleven of the water bodies had less
median total phosphorus, 14 had less median dissolved orthophos-
phorus, ten had less median inorganic nitrogen, six had less mean
chlorophyll a_, and four had greater mean Secchi disc transparency.
No significant depression of dissolved oxygen occurred at depths
as great as 71.6 meters.
Survey limnologists noted some surface concentrations of algae
in September.
B. Rate-Limiting Nutrient:
The algal assay results indicate the reservoir was nitrogen
limited in June. The reservoir data indicate nitrogen limitation
at all sampling times.
C. Nutrient Controllability:
1. Point sources--Koocanusa Reservoir is an international
water body, and about 17% of the volume, 38% of the surface area,
and 86% of the drainage area are in Canada (Bonde, 1976). Because
* See Appendix A.
-------
2
Canadian tributaries were not sampled during this study, it is
not possible to calculate overall nutrient loadings to the reser-
voir.
The only known point source in Montana is the Eureka waste-
water treatment plant which contributed an estimated 6.9% of
the total phosphorus loading originating in the U.S. portion
of the drainage during the sampling year.
If the total phosphorus loading from the entire drainage basin
during the sampling year is assumed to equal the phosphorus load
leaving the reservoir, the reservoir received a loading amounting
to about 90% of that proposed by Vollenweider (Vollenweider and
Dillon, 1974) as a eutrophic loading (see page 11). Undoubtedly
this is a conservative estimate since the reservoir has a mean
hydraulic retention time of 271 days and would be expected to retain
from 40 to 60 percent of the incoming phosphorus load.
2. Non-point sources—It is estimated that non-point sources
contributed about 93% of the phosphorus loading originating in the
U.S. portion of the drainage basin during the sampling year. The
Tobacco River added 47% of the total U.S. load.

III. WATER QUALITY SUMMARY
Koocanusa 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 a number of depths at 5 or 6 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 first visit, two 18.9-
liter depth-integrated samples were 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 sam-
pled were 52.4 meters at station 1, 70.1 meters at station 2, 71.6
meters at station 3, 58.8 meters at station 4, 56.7 meters at station
5, and 44.5 meters at station 6.
The sampling results are presented in full in Appendix D and
are summarized in the following table.

2. Discussion -
The control yields of the assay alga, Selenastrum capri-
cornutum, indicate that the potential primary productivity
of Koocanusa Reservoir was moderately high to high at the
time the samples were collected (06/02/75). Also, signifi-
cant increases in yields with the addition of nitrogen
alone indicate the reservoir was nitrogen limited at that
time.
The reservoir data also indicate nitrogen limitation; i.e.,
the mean inorganic nitrogen/orthophosphorus ratios were 3/1
or less at all sampling times.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Montana National
Guard collected monthly near-surface grab samples when possible from
each of the U.S. 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 U.S.
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 the unsampled U.S. portion of the "minor tributaries
and immediate drainage" ("II" of U.S.G.S.) were estimated using the
means of the nutrient loads, in kg/km 2/year, at stations B-l and C-l
and multiplying the means by the U.S. II area in km2.
The operator of the Eureka wastewater treatment plant provided
monthly effluent samples and corresponding flow data; note, however,
the flows appear to be estimated (see Appendix E).

F. Yearly Loads:
In the following table, the phosphorus loadings that would
exist if inputs equaled outputs 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 oligo-
trophic 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.
