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)],
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, arid 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 Canyon Ferry Reservoir is eutrophic.
It ranked last in overall trophic quality when the 15 Montana
lakes and reservoirs sampled in 1975 were compared using a combi-
nation of six water quality parameters*. Twelve of the water
bodies had less median total phosphorus, 13 had less median dis-
solved orthophosphorus, 12 had less median inorganic nitrogen,
11 had less mean chlorophyll a_, and 11 had greater mean Secchi
disc transparency. Depression of dissolved oxygen with depth
occurred at stations 2 and 3 in July and at station 4 in September.
Survey limnologists noted a bloom of filamentous algae at
stations 2, 3, 4, and 5 during the July sampling and submerged
macrophytes at station 1 in September. The periodic dominance
of blue-green algae in late summer has been noted in reports of
limnological investigations of the reservoir (Wright, 1958; 1959;
1960; 1961; 1965).
B. Rate-Limiting Nutrient:
The algal assay results indicate that Canyon Ferry Reservoir
was nitrogen limited at the times the samples were collected (09/
04/75 and 10/22/75). The reservoir data indicate nitrogen limi-
tation at all sampling stations and times except for station 1 in
September.
* See Appendix A.

C. Nutrient Controllability:
1. Point sources—During the sampling year,
point sources contributed less than 0.5% of the total phos-
phorus load to Canyon Ferry Reservoir. The wastewater treat-
ment plant at Townsend contributed 0.4%, and septic tanks
serving shoreline dwellings and campgrounds were estimated to
have contributed less than 0.1%. In addition, a wastewater
treatment plant of unknown significance at Bozeman was not
included as a point source since it is beyond the 40-kilometer
limit of the Survey* (see map, page v).
The present phosphorus loading of 2.27 g/m2/year is
twice that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 16). The phosphorus
loadings of 2.85 g/m2/yr and 2.44 g/m2/yr, derived from the 1971
and 1972 phosphorus budgets prepared by Wright et al. (1974), support
the Survey findings and indicate the need for nutrient control
to establish a more persistent phosphorus-limited condition and
slow the present rate of eutrophication of the reservoir.
2. Non-point sources--Non-point sources contributed over
99% of the total phosphorus load during the sampling year. The
Missouri River contributed 97.8%, Beaver Creek contributed 0.2%,
and Confederate Creek contributed 0.1%. The ungaged minor tribu-
taries and immediate drainage contributed an estimated 0.7%.
* See Working Paper No. 175, "...Survey Methods, 1973-1976".

As noted above, part of the phosphorus load in the Missouri
River may be due to the Bozeman wastewater treatment plant
effluent rather than non-point sources. In addition, irrigation
in the drainage basin also may be significant. An additional
study is needed to determine the contribution and significance
of all point and non-point sources impacting the Missouri River
and its tributaries upstream from the reservoir.

III. WATER QUALITY SUMMARY
Canyon Ferry Reservoir was sampled four 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 five 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 September
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 1.5 meters at station
1, 13.7 meters at station 2, 24.1 meters at station 3, 34.4 meters
at station 4, and 50.3 meters at station 5.
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 Canyon Ferry Reservoir was relatively high at the times
the samples were collected (09/04/75 and 10/22/75). Also,
in all three assays, the lack of growth response with the
addition of phosphorus alone until nitrogen was also added
indicates that the reservoir was limited by nitrogen at those
times. Note that the addition of nitrogen alone resulted in
yields significantly greater than those of the controls in all
assays.
The reservoir data indicate nitrogen limitation at all
stations with the exception of station 1 in September; i.e.,
the mean inorganic nitrogen/orthophosphorus ratios were 12/1
-------
11
or less and nitrogen limitation would be expected. However,
the September N/P ratio at station 1 was 15/1, and phosphorus
limitation would be expected there.
Nitrogen limitation, as indicated by the algal assay or
by in-reservoir nitrogen to phosphorus ratios, does not necessarily
mean that the trophic condition of the reservoir can be improved
by controlling nitrogen inputs. In many cases, the apparent
condition of nitrogen-limitation results from excessive phos-
phorus input from point sources and is often accompanied by a
corresponding increase in primary production. In such cases,
the reversal of the enriched condition depends upon phosphorus
control, not nitrogen control.

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" ("II" of U.S.G.S.) were estimated using the means of the
nutrient loads, in kg/km2/year, at stations B-l, E-l, and G-l and
multiplying the means by the II area in km2.
The operator of the Townsend 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.
