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)]s 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.
-------
iii
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 cf this Working Paper series.
Major General 'John 0. 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 Tiber Reservoir is meso-eutrophic.
It ranked eighth 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*. Six of the water
bodies had less median total phosphorus, two had less and three
had the same median dissolved orthophosphorus, 13 had less and
one had the same median inorganic nitrogen, seven had less mean
chlorophyll £, and 12 had greater mean Secchi disc transparency.
Dissolved oxygen was not significantly depressed at depths as
great as 42.7 meters.
Survey limnologists did not observe nuisance aquatic plants
or surface concentrations of algae during their visits but
noted that the water at times was quite turbid. Turbidity appears
to be a major problem in this water body; it Is noted in another
study that the shores are steep, soft, and easily eroded, and
because of the resulting turbidity, phytoplankton numbers are low
(Stober, 1963).
* See Appendix A.

B. Rate-Limiting Nutrient:
The algal assay results indicate that Tiber Reservoir was
limited by phosphorus at the time the sample was taken (09/09/
75). The reservoir data indicate phosphorus limitation in July
and September (with the exception of station 6 in September) and
a combination of limiting nutrients in May. However, because of
turbidity (Stober, op. cit.), primary productivity may be light-
limited at times.
C. Nutrient Controllability:
1. Point sources—During the sampling year, the wastewater
treatment facility at Shelby contributed 13.7% of the total phos-
phorus input to Tiber Reservoir. In addition, three other facil-
ities of unknown significance at Valier, Cut Bank, and Browning
were not included since they are beyond the 40-kilometer Survey
limit* (see map, page v). Further investigation is needed to
determine the significance of nutrient contributions from those
sources; however, the nutrient export rates of the Marias River
indicate minimal impact (see below).
The present phosphorus loading of 0.64 g/m2/year is more than
that proposed by Vollenweider (Vollenweider and Dillon, 1974)
as an oligotrophic loading but less than his eutrophic loading
(see page 14). Since the reservoir is phosphorus limited dur-
ing much of the year, minimization of point-source loads could
be considered as a means to maintain the present water quality,
particularly if soil-conservation practices are initiated
to reduce erosion in the drainage basin and the resulting

turbidity in the reservoir.
2. Non-point sources--Non-point sources accounted for
86.3% of the total phosphorus load during the sampling year.
The Marias River contributed 67.9% and Willow Creek contri-
buted 10.3%. The ungaged minor tributaries and immediate
drainage were estimated to have contributed 5.4%.
The phosphorus export rate of the Marias River was a
low 2 kg/m2 during the sampling year as was that of unim-
pacted Willow Creek. This indicates the distant point
sources noted above probably were not significant contri-
butors of phosphorus during the sampling year.

III. WATER QUALITY SUMMARY
Tiber 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 one or more depths at six 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 last
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 sampled were 1.5 meters at station 1, 25.9 meters at station
2, 18.6 meters at station 3, 19.8 meters at station 4, 42.7 meters
at station 5, and 7.3 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 cajari-
cornutum, indicate that the potential primary productivity
of Tiber Reservoir was moderate at the time the samples
were taken (09/09/75). Also, the increases in yields with
the addition of phosphorus alone indicate the reservoir
was phosphorus limited at that time. Note that increased
yields did not result with the addition of nitrogen alone.
The reservoir data indicate phosphorus limitation in
July and September, with the exception of station 6, and a
combination of limiting nutrients is indicated in May.
Following is a tabulation of the mean inorganic nitrogen/
-------
orthophosphorus ratios at 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 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 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" ("ZZ" of U.S.G.S.) were estimated using the nutrient loads
at station D-l, in kg/km 2/year, and multiplying by the ZZ area in km2.
The operator of the Shelby wastewater treatment plant provided
monthly effluent samples and corresponding flow data.

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 Ni trogen
Total Accumulated Jotal Accumulated
grams/m2/yr 0.64 0.36 34.6 19.9
Vollenweider phosphorus loadings
