                          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)j, clean lakes [§3l4(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, 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 Koocanusa Reservoir is  mesotrophic.
        It ranked eleventh in overall  trophic quality when the 15  Montana
        lakes and reservoirs sampled in  1975 were compared using a com-
        bination of six parameters*.  Eleven of the water bodies had  less
        median total  phosphorus, 14 had  less median dissolved orthophos-
        phorus, ten had less median inorganic nitrogen,  six had less  mean
        chlorophyll a_,  and four had greater mean Secchi  disc  transparency.
        No significant depression of dissolved oxygen occurred at  depths
        as great as 71.6 meters.
            Survey limnologists noted some surface concentrations  of  algae
        in September.
    B.  Rate-Limiting Nutrient:
            The algal assay results indicate the reservoir was nitrogen
        limited in June.  The reservoir  data indicate nitrogen limitation
        at all sampling times.
    C.  Nutrient Controllability:
            1.  Point sources--Koocanusa Reservoir is an international
        water body, and about 17% of the volume, 38% of  the surface area,
        and 86% of the drainage area are in Canada (Bonde, 1976).   Because
* See Appendix A.

-------
                             2
Canadian tributaries were not sampled during this study, it is
not possible to calculate overall nutrient loadings to the reser-
voir.
    The only known point source in Montana is the Eureka waste-
water treatment plant which contributed an estimated 6.9% of
the total phosphorus loading originating in the U.S. portion
of the drainage during the sampling year.
    If the total phosphorus loading from the entire drainage basin
during the sampling year is assumed to equal  the phosphorus load
leaving the reservoir, the reservoir received a loading amounting
to about 90% of that proposed by Vollenweider (Vollenweider and
Dillon, 1974) as a eutrophic loading (see page 11).  Undoubtedly
this is a conservative estimate since the reservoir has a mean
hydraulic retention time of 271  days and would be expected to retain
from 40 to 60 percent of the incoming phosphorus load.
    2.  Non-point sources—It is estimated that non-point sources
contributed about 93% of the phosphorus loading originating in the
U.S. portion of the drainage basin during the sampling year.  The
Tobacco River added 47% of the total U.S. load.

III.   WATER QUALITY SUMMARY
      Koocanusa 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 a number of depths at 5 or  6 stations on the  reservoir (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, 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 sam-
  pled were 52.4 meters at station 1,  70.1  meters  at station 2,  71.6
  meters at station 3,  58.8 meters at station 4, 56.7  meters at station
  5,  and 44.5 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 capri-

        cornutum,  indicate that the potential  primary productivity

        of Koocanusa Reservoir was moderately  high to high  at the

        time the samples were collected (06/02/75).   Also,  signifi-

        cant increases in yields with the addition of nitrogen

        alone indicate the reservoir was nitrogen  limited at  that

        time.

            The reservoir data also indicate nitrogen limitation; i.e.,

        the mean inorganic nitrogen/orthophosphorus ratios  were  3/1

        or less at all sampling times.

IV.   NUTRIENT LOADINGS
     (See Appendix E for data)
     For the determination of nutrient loadings,  the  Montana  National
 Guard collected monthly near-surface grab samples when  possible  from
 each of the U.S.  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 U.S.
 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 the unsampled U.S.  portion of the  "minor  tributaries
 and immediate drainage" ("II"  of  U.S.G.S.) were  estimated using  the
 means of the nutrient loads,  in kg/km 2/year, at  stations  B-l and C-l
 and multiplying the means by the  U.S.  II  area  in km2.
     The operator of the Eureka wastewater treatment  plant provided
 monthly effluent samples and corresponding flow  data; note,  however,
 the flows appear to be estimated  (see Appendix E).

    F.  Yearly Loads:
            In the following table,  the phosphorus loadings  that would
        exist if inputs equaled outputs 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 oligo-
        trophic 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.

         (g/m2/yr)  based on mean depth and mean
         hydraulic  retention time of Koocanusa  Reservoir:
            "Dangerous"   (eutrophic loading)             1.36
            "Permissible"  (oligotrophic  loading)        0.68
* Based on outlet load,  assuming inlet load  is  at least equal  to  outlet  load.
