                          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)3, water
quality criteria/standards review [§303(c)l, clean lakes [§314(a.t>)],
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
freshwater 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.

ACKNOWLEDGMENT

    The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Wyoming Department of Environ-
mental Quality for professional involvement, to the Wyoming National
Guard for conducting the tributary sampling phase of the Survey,
and to those Wyoming wastewater treatment plant operators who
voluntarily provided effluent samples.

    The staff of the Water Quality Division 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.

    Brigadier General  James L. Spence, The Adjutant General  of
Wyoming, and Project Officer Colonel Donald L.  Boyer,  who directed
the volunteer efforts  of the Wyoming National Guardsmen, are also
gratefully acknowledged for their assistance to the Survey.

    I.  CONCLUSIONS
        A.  Trophic Condition:
                Survey data indicate that Ocean Lake is eutrophic.  It
            ranked fifth in overall trophic quality when the 14 Wyoming
            lakes and reservoirs sampled in 1975 were compared using a
            combination of six water quality parameters*.  Eight of the
            water bodies had less median total phosphorus, three had
            less and one had the same median dissolved orthophosphorus,
            none had less but four had the same median inorganic nitro-
            gen, eight had less mean chlorophyll a_, and 12 had greater
            mean Secchi disc transparency.
                Survey limnologists noted that the lake had a milky
            green appearance during the September sampling, and the
            chlorophyll ^concentration and numbers of phytoplankton
            in October indicate a light bloom (see page 6).  In a
            previous report it is suggested that eutrophication of
            this waterbody probably is responsible for changes in
            the abundance of certain species of fish (Anonymous, 1974).
        B.  Rate-Limiting Nutrient:
                The algal assay results are not considered representative
            of conditions in the lake at the times the samples were taken
* See Appendix A.

                             2
    (05/19/75 and 10/16/75)  due to  significant changes  in
    nutrient levels during sample shipment from the field  to
    the laboratory.
        The lake data indicate  nitrogen limitation in May  and
    October and phosphorus limitation in September.
C.  Nutrient Controllability:
        1.   Point sources—The  only known point source, the
    Pavillion wastewater treatment plant, contributed 1.1% of
    the total phosphorus input  to Ocean Lake during the samp-
    ling year.
        The present phosphorus  loading of 0.26 g/m2/year is more
    than that proposed by Vollenweider (Vollenweider and Dillon,
    1974) as a eutrophic loading.  However, since the point-source
    load is relatively small, any improvement in the present  tro-
    phic condition is dependent on control of non-point sources.
        2.   Non-point sources--Non-point sources accounted for
    98.9% of the total phosphorus load during the sampling year.
    Pilot Drain contributed 55.7%,  Unnamed Creek F-l contributed
    26.5%,  Unnamed Creek H-l contributed 2.1%, and the  Sand Butte
    Aqueduct (stations E-l and  E-2, collectively) contributed
    6.0%.  The ungaged minor tributaries and immediate  drainage
    contributed an estimated 2.0% of the total.
        Areas surrounding the lake are used extensively for farm-
    ing.   As a consequence,  nutrient loads in irrigation return  flows
    and natural  runoff probably are the most significant contributors
    to the  enrichment of the lake.   A further study is  needed to
    determine the controllability of nutrients from such sources.

III.   WATER QUALITY SUMMARY
     Ocean Lake 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 num-
 ber of depths at  one station on the lake  (see  map,  page v).  During
 each visit, a single depth  integrated  (4.6 m to  surface)  sample was col-
 lected for phytoplankton identification and  enumeration and a similar
 sample was collected for chlorophyll a_ analysis.  During  the first and
 last visits,  a single  18.9-liter  depth-integrated sample  was taken for
 algal assays.  The maximum  depth  sampled  was 6.4 meters.
     The sampling  results are presented  in full in Appendix D and are
 summarized in the following table.

C.   Limiting Nutrient Study:
        Due to significant changes in nutrient levels in the samples
    during shipment from the field to the laboratory, the algal
    assay results are not considered representative of conditions  in
    the lake at the time the samples were collected (05/19/75 and
    10/16/75).
        The lake data indicate nitrogen limitation in May and
    October and phosphorus limitation in September; i.e., the
    mean inorganic nitrogen/orthophosphorus ratios were 3/1  and
    10/1 in May and October,  respectively, and 14/1 in September.

IV.   NUTRIENT LOADINGS
     (See Appendix E for data)
     For the determination of nutrient loadings,  the Wyoming  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 at six  of the
 sites.   Sampling was begun in  October,  1974,  and was completed in
 August, 1975.
     Through an interagency agreement, stream  flow  estimates  for the
 year of sampling and a "normalized"  or average year were provided by
 the Wyoming District Office of the U.S.  Geological  Survey  for  the
 tributary sites near the lake.
     In  this report,  nutrient loads for sampled tributaries were
 calculated using mean annual concentrations and  .mean annual  flows.  Nu-
 trient 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 mean concentrations
 in  Sand Butte Aqueduct at stations E-l  and E-2 and the mean  annual II
 flow.
     The operator of the Pavillion wastewater  treatment plant provided
 monthly effluent samples and corresponding flow  data.

D.   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.

     (g/m2/yr) based on mean depth and mean
     hydraulic retention time of Ocean Lake:
        "Dangerous"  (eutrophic loading)                0.20
        "Permissible"  (oligotrophic loading)           0.10
