                          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 ANALYSI
    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 p'larming [§303(c)], 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.

-------
                                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.

I.   CONCLUSIONS
    A.   Trophic Condition:
            Survey data indicate Brownlee Reservoir is eutrophic.
        It ranked twentieth in overall  trophic quality when the 21
        Oregon and Idaho lakes and reservoirs sampled in 1975 were  com-
        pared using a combination of six water quality parameters*.
        Eighteen of the water bodies had less median total  phosphorus,
        dissolved orthophosphorus, and  inorganic nitrogen;  17 had  less
        mean chlorophyll £; and 15 had  greater mean Secchi  disc trans-
        parency.  Marked depression of  dissolved oxygen with depth
        occurred at sampling stations 2, 3, and 4 in August and at
        stations 2 and 3 in September,  and depletion occurred during
        a previous study of the reservoir (Ebel and Koski,  1968).
            Survey limnologists reported surface concentrations of
        algae at station 1  in September.  The concentrations of chlorophyll
        a^ at stations 2, 3, 4, and 5 in April (see page 7)  indicate
        possible bloom conditions at that time as well.
    B.   Rate-Limiting Nutrient:
            The algal assay results are not considered representative of
        conditions in the reservoir at  the time the samples were col-
        lected (04/19/75 and 09/15/75)  due to significant nutrient
        changes during shipment of the  samples from the field to the
        laboratory.
* See Appendix A.

-------
                                     2
            The reservoir data indicate phosphorus limitation at four
        of the five sampling stations in April, nitrogen limitation at
        four of the stations in August, and nitrogen limitation at all
        stations in September.
    C.  Nutrient Controllability:
            1.  Point sources—The wastewater treatment plants at Hun-
        tington, Oregon, and Weiser, Idaho, collectively contributed
        an estimated 0.2% of the total phosphorus load to Brownlee
        Reservoir during the sampling year.  However, other municipal
        and industrial point sources in the drainage basin beyond the
        40-kilometer limit of the Survey* probably are significant
        contributors (see page 10).
            The sampling year phosphorus loading of 33.47 g/m2 is nearly
        ten times that proposed by Vollenweider (Vollenweider and Dil-
        lon, 1974) as a eutrophic loading (see page 14).   Although
        Vollenweider's model may not be applicable to water bodies with
        .short hydraulic retention times, the trophic condition of Brownlee
        Reservoir is evidence of excessive nutrient loads.
            2.  Non-point sources—As considered in this report, "non-
        point" sources include those contributing nutrients as a result  of
        human activities (e.g., agricultural  practices, urbanization,
        extractive processes, etc.)  as well as natural  sources (i.e.,
        direct precipitation, leaf fall, wild birds and animals, etc.).
            The apparent non-point source contribution accounted for 99.8%
* See Working Paper No.  175,  "...Survey Methods,  1973-1976".

-------
                             3
of the total phosphorus load during the sampling year.   However,
as noted above, part of this load is attributable to point sources
further upstream.
    The Snake River contributed 95.3% of the total  phosphorus
load, the Powder River contributed 2.0%, and four other gaged
tributaries collectively contributed 2.2%.   The ungaged minor
tributaries and immediate drainage contributed an estimated 0.2%.
    While substantial point-source inputs occur upstream on
the Snake River, in a previous report it is noted that  up to
44% of the nutrient load in the river comes from agricultural
sources (Anonymous, 1974).   Also, in Oregon, agricultural runoff
and irrigation return flows have been noted as the major contributors
to the nutrient loads in the Burnt, Powder, and Pine rivers (Anony-
mous, 1969).  Any improvement in the trophic condition  of Brownlee
Reservoir would involve minimization of nutrients from  the non-
point as well as point sources in the drainage basin.

III.   WATER QUALITY SUMMARY
      Brownlee 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 five  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 and last 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  ^analysis.  The maximum depths samples  were 18.9  meters
  at station 1, 64.0 meters at station 2 and 3, 32.3 meters at station 4,
  and 18.6 meters  at station  5.
      The sampling results are presented in full  in Appendix D and are
  summarized in the following table.

C.  Limiting Nutrient Study:

        The algal  assay results are not considered representative of

    conditions in the reservoir at the time the samples were taken

    (04/09/75 and 09/15/75) due to significant nutrient changes in

    the samples during shipment from the field to the laboratory.

        The reservoir data indicate a combination of limiting nutrients.

    Following is a tabulation of the mean inorganic nitrogen/ortho-

    phosphorus ratios for each of the sampling stations and times

    with the indicated limiting nutrient in parentheses.

IV.   NUTRIENT LOADINGS
     (See Appendix E for data)
     For the determination of nutrient loadings,  the Oregon  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 January and February 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 Oregon District Office of the U.S.  Geological  Survey  for the tribu-
 tary sites nearest the reservoir.
     In this report, nutrient loads for sampled tributaries  were deter-
 mined 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 drain-
 age" ("II" of U.S.G.S.) were estimated using  the means of the nutrient
 loads, in kg/km2/year, at stations G-l  and K-l and  multiplying  the means
 by  the II area in km2.
     The operators of the Huntington,  OR and Weiser, ID wastewater treat-
 ment plants did not participate; nutrient loads from these  sources were
 estimated at 1.134 kg P and 3.401  kg N/capita/year, and flows were esti-
 mated at 0.3785 m3/capita/day.

            In addition, there are at least 27 other municipal  waste-
        water treatment facilities beyond the 40-kilometer Survey
        limit**.  These facilities collectively serve 228,880 people
        and discharge 196,435 m3/day.  Except for the plants at Vale,
        Ontario, and Baker, Oregon, most of these plants discharge into
        the Snake River and its tributaries in Idaho.
            2.  Known industrialt--At least 31 industries are known
        to discharge within the drainage basin in Oregon and Idaho.
        These include sugar-beet, potato, and other agricultural pro-
        cessing plants; fish hatcheries; car washes; timber processing;
        a phosphate reduction plant; and a cement plant.

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.
