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,
a.nd 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 [f»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
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 Hater 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 Tally Lake is oligo-mesotrophic.
It ranked fourth in overall trophic quality when the 15 Montana
lakes and reservoirs sampled in 1975 were compared using a com-
bination of six parameters*. Four of the water bodies had less
median total phosphorus, five had less and three had the same
median inorganic nitrogen, two had less and three had the same
median orthophosphorus, three had less mean chlorophyll a_, and
five had greater mean Secchi disc transparency. No significant
depression of dissolved oxygen occurred at depths as great as 52
meters.
Survey limnologists did not observe any nuisance conditions
and commented on the attractive appearance of the lake.
B. Rate-Limiting Nutrient:
Due to significant nutrient changes in the algal assay samples,
the assay results are not considered representative of conditions
in the lake at the times of sampling.
The lake data indicate nitrogen limitation in June and
phosphorus limitation in July and September.
C. Nutrient Controllability:
1. Point sources—No known municipal or industrial point

sources impacted Tally Lake during the sampling year. Septic
tanks serving a lakeshore dwelling and a campground were esti-
mated to have contributed 0.2% of the total phosphorus load,
but a shoreline survey would be necessary to determine the actual
significance of those sources.
The present phosphorus loading of 0.51 g/m 2/year is slightly
more than that proposed by Vollenweider (Vollenweider and Dillon,
1974) as an oligotrophic loading, and every effort should be
made to keep phosphorus inputs at the lowest practicable level to
protect the existing trophic quality of Tally Lake.
2. Non-point sources--Non-point sources, including precipita-
tion, accounted for 99.8% of the total phosphorus load to Tally
Lake during the sampling year. Logan Creek contributed 80.9% of
the total load, and the ungaged tributaries added an estimated 15.5%
of the total.
The non-point phosphorus export rate of Logan Creek was 5 kg/km2/
yr. This rate is quite low as compared to the rates of two
unimpacted tributaries of nearby Whitefish Lake* (9 and 21 kg/km2/yr).

III. WATER QUALITY SUMMARY
Tally 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 on the lake (see map, page v).
During each visit, a single depth-integrated (4.6 m to surface)
sample was composited from the stations for phytoplankton identifi-
cation and enumeration; and during the first and last visit, 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 depth sampled
at both stations was 51.8 meters.
The sampling results are presented in full in Appendix D and
are summarized in the following table.

C. Limiting Nutrient Study:
Due to significant nutrient changes in the algal assay sam-
ples during shipment from the field to the laboratory, the
results are not considered representative of lake conditions
at the times of sampling (06/02/75 and 09/05/75).
The lake data indicate Tally Lake was nitrogen limited in
June and phosphorus limited in July and September. At those
times, the mean inorganic nitrogen to orthophosphorus ratios
were 5 to 1, 16 to 1, and 19 to 1, respectively.
-------
IV. NUTRIENT LOADINGS
(See Appendix £ 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 months of May and June when two samples were collected.
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 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" ("ZZ" of U.S.G.S.) were
estimated using the nutrient loads, in kg/km2/year, at station A-2
and multiplying by the ZZ area in km2.
No known wastewater treatment plants impacted Tally Lake during
the sampling year.

E. 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/m2/yr 0.51 0.13 34.4 2.6
Vollenweider phosphorus loadings
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Tally Lake:
"Dangerous" (eutrophic loading) 0.96
"Permissible" (oligotrophic loading) 0.48
