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)]5 water
quality criteria/standards review [§303(c)j, clean lakes [§314(a,b)J,
and water quality monitoring [§106 and §305(b)] activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.
-------
111
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 Seeley Lake is meso-eutrophic.
It ranked sixth in overall trophic quality when the 15 Montana
lakes and reservoirs sampled in 1975 were compared using a com-
bination of six water quality parameters*. Five of the water
bodies had less median total phosphorus, nine had less median
dissolved orthophosphorus, none of the others had less but four
had the same median inorganic nitrogen, four had less mean chloro-
phyll ju and six had greater mean Secchi disc transparency. Marked
depression of dissolved oxygen with depth occurred at stations 1
and 2 in September.
Survey limnologists noted submerged and emergent macrophytes
along the shoreline during the September sampling. Periodic domi-
nance of blue-green algae in the early autumn and abundant emer-
gent macrophytes have been noted in another study (Cladouhos, 1971).
B. Rate-Limiting Nutrient:
The algal assay results are not considered representative of
conditions in the lake at the time the samples were collected
(05/28/75 and 09/04/75) due to significant changes in nutrient
concentrations during shipment of the samples from the field to
the laboratory.
* See Appendix A.

The lake data indicate nitrogen limitation at all stations
and sampling times with the exception of station 3 in September.
C. Nutrient Controllability:
1. Point sources—No known municipal or industrial point
sources impacted Seeley lake during the sampling year. Septic
tanks serving lakeshore dwellings, resorts, and campgrounds are
estimated to have contributed 1.2% of the total phosphorus load;
however, a shoreline survey would be necessary to determine the
actual contributions of those sources.
The present phosphorus loading of 0.97 g/m2/year is more than
that proposed by Vollenweider (Vollenweider and Dillon, 1974) as
an oligotrophic loading but less than his suggested eutrophic
loading (i.e., a mesotrophic loading; see page 11). Cladouhos
(op. cit.) notes that Seeley Lake is potentially productive due
to its morphometry, including the unique position of the outlet
which causes poor circulation in the southern portion of the lake
and accumulation of nutrients there.
2. Non-point sources—Non-point sources contributed 98.8% of
the total phosphorus input during the sampling year. The Clear-
water River contributed 64.6%, Deer Creek contributed 21.0%, and
Seeley Creek contributed 1.5%. Ungaged minor tributaries and
immediate drainage contributed an estimated 9.9% of the total.
A study of land-use practices in the drainage is needed to
determine whether any significant reduction of non-point nutrient
inputs can be accomplished.

III. WATER QUALITY SUMMARY
Seeley Lake 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 two stations in May and July and from three
stations in September (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 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 18.9 meters at station
1, 34.1 meters at station 2, and 7.9 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 representative of
conditions in the lake at the times the samples were collected
(05/28/75 and 09/04/75) due to significant changes in nutrient
levels during shipment of the samples from the field to the
laboratory.
The lake data indicate nitrogen limitation at all sampling
stations and times with the exception of station 3 in September.
Following is a tabulation of the mean inorganic nitrogen/ortho-
phosphorus ratios for each sampling station and time with the
indicated limiting nutrient in parentheses.

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), except for the high
runoff month of July when two samples were collected at most of the
sites. Sampling was begun in October, 1974, and was completed in Sep-
tember, 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 lake.
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 for unsampled "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 E-l and multi-
plying the means by the II area in km2.
No known wastewater treatment plants impacted Seeley Lake during the
sampling year.

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.
Total Phosphorus Total Nitrogen
Total Accumulated Total Accumulated
grams/mz/yr 0.97 0.37 21.8 loss*
Vollenweider phosphorus loadings
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Seeley Lake:
"Dangerous" (eutrophic loading) 1.36
"Permissible" (oligotrophic loading) 0.68
* There was an apparent loss of nitrogen during the sampling year. This may
have been due to nitrogen fixation in the lake, solubilization of previously
sedimented nitrogen, recharge with nitrogen rich ground water, unknown and
unsampled point sources, or underestimation of the nitrogen loads from lake-
shore dwellings. Whatever the cause, a similar nitrogen loss has occurred
at Shagawa Lake, Minnesota, which has been intensively studied by EPA's
former National Eutrophication and Lake Restoration Branch (Malueg et al.,
1975).
