                          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".

-------
                             3
    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.
