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)], clean lakes [§314(a,b)J,
and water quality monitoring [§106 atid §305(b)j activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.
-------
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.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake McDonald is oligotrophic. It
ranked second in overall trophic quality when the 15 Montana
lakes and reservoirs sampled in 1975 were compared using a com-
bination of six parameters*. None of the other water bodies had
less median total phosphorus, median dissolved orthophosphorus,
or mean chlorophyll aj> 13 had less and one had the same median
inorganic nitrogen; and none of the others had greater mean Secchi
disc transparency.
Survey limnologists noted some submerged macrophytes in July.
B. Rate-Limiting Nutrient:
The algal assay results indicate the lake was phosphorus limited
in June. The lake data indicate phosphorus limitation in July as
well.
C. Nutrient Controllability:
1. Point sources—It is calculated that known point sources
contributed only 2.1% of the total phosphorus load received by
Lake McDonald during the sampling year. The Lake McDonald Lodge
wastewater treatment plant was the major contributor (1.4%).
* See Appendix A.
-------
2
In May of 1976, nutrients from these sources were eliminated
by diversion to the new Lake McDonald Valley wastewater treat-
ment plant with effluent disposal by spray irrigation outside the
Lake McDonald drainage basin (Gingery, 1976).
During the sampling year, the lake received a total phos-
phorus loading amounting to about 81% of that proposed by Vollen-
weider (Vollenweider and Dillon, 1974) as a permissible loading
(see page 12). Therefore, elimination of the known point source
loads may not result in significant improvement in the water
quality in the lake. Nevertheless, minimization of phosphorus
inputs to the lake will provide protection for the existing tro-
phic condition.
2. Non-point sources—It is estimated that non-point inputs
accounted for about 98% of the total phosphorus load to the lake
during the sampling year. McDonald Creek contributed 79% of the
total load, and the three remaining gaged tributaries collectively
contributed 8.1%.
The phosphorus export rates of McDonald and Snyder creeks were
relatively high compared to the 8 kg/km2/year mean rate of 37
Montana streams gaged and sampled during the Survey. The higher
rate of Snyder Creek may have resulted from underestimation of
the point-source load, but the cause of the higher rate of unim-
pacted McDonald Creek is not obvious since the entire drainage
of the creek is within Glacier National Park.

III. WATER QUALITY SUMMARY
Lake McDonald was sampled two times during the open-water season
of 1974 by means of a pontoon-equipped Huey helicopter. Each time,
samples for physical and chemical parameters were collected from
a number of depths at three 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 identification
and enumeration; and during the first 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 each station
was 61.0 meters.
The sampling results are presented in full in Appendix D and
are summarized in the following table.

of the assay alga, Selenastrum capri-
cornutum, indicates that the potential primary productivity
of Lake McDonald was relatively low at the time the sample
-------

was collected (06/01/75). Also, a significant increase in
yield with the addition of phosphorus alone indicates the lake
was phosphorus limited at that time. Note that the addition
of nitrogen alone resulted in a yield which was not signifi-
cantly different from that of the control.
The lake data indicate phosphorus limitation both sam-
pling times (the mean inorganic nitrogen/orthophosphorus
ratios were at least 25/1 in June and 74/1 in July, respec-
tively).

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 months of May and June when two samples were collected.
Sampling was begun in October, 1974, and was completed in September,
1975.
Through an i'nteragency 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 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 means of the
nutrient loads, in kg/km 2/year, at stations B-l and E-l and multi-
plying by the ZZ area in km2.
The operator of the Lake McDonald Lodge wastewater treatment plant
did not participate in the Survey, and nutrient loads from the plant
were estimated using 1.134 kg P and 3.401 kg N/capita/year. The oper-

ation of this plant, which previously was from May through September
each year (the peak visitation period at Glacier National Park), was
discontinued in September, 1975. Sewage from the lodge is now treated
at the new Lake McDonald Valley wastewater treatment plant along with
wastes previously treated in septic tanks. The new plant was initially
opened in May of 1976 and will operate on a May through September basis
(Gingery, op. cit.).

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.
