                          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.

-------
                                 m
    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 South Carolina Department
of Health and Environmental Control for professional involvement,
to the South Carolina National Guard for conducting the tributary
sampling phase of the Survey, and to those South Carolina waste-
water treatment plant operators who voluntarily provided effluent
samples and flow data.

    The staff of the South Carolina Bureau of Wastewater and
Stream Quality Control 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 Robert L. McCrady, the Adjutant General of South
Carolina, and Project Officer Lt. Colonel John P. DuPre (Retired),
who directed the volunteer efforts of the South Carolina National
Guardsmen, are also gratefully acknowledged for their assistance
to the Survey.

I.  CONCLUSIONS
    A.  Trophic Condition:
            Survey data indicate that Lake William C.  Bowen is  meso-
        eutrophic.  It ranked seventh in overall  trophic quality when
        the 13 South Carolina lakes sampled in 1973 were compared using
        a combination of six parameters*.   Three  of the lakes  had less
        median total phosphorus, six had less and one  had the  same median
        dissolved phosphorus, nine had less median inorganic nitrogen,
        three had less mean chlorophyll a_, and five had greater mean
        Secchi disc transparency.
            No nuisance conditions were noted by  Survey 1imnologists;
        however, some emergent vegetation  was observed in the  shallow
        areas near sampling station one, and oxygen depression  or depletion
        occurred at station three.
    B.  Rate-Limiting Nutrient:
            The algal assay results show phosphorus limitation  at the time
        the sample was collected (03/29/73).  The lake data indicate  phos-
        phorus limitation at all sampling  times.
    C.  Nutrient Controllability:
            1.  Point sources--The phosphorus contribution of  the Landrum
        wastewater treatment plant accounted for  9.7%  of the total  load
        reaching the lake.
* See Appendix A.

-------
                             2
    During the sampling year, the lake received a total  phos-
phorus loading only slightly more than that proposed by  Vollen-
weider (Vollenweider and Dillon, 1974} as an oligotrophic  loading
(see page 11).  However, the hydraulic retention time of the
lake is not known, and it is possible that Vollenweider's  model
is not applicable.  Also, the apparent loss of phosphorus  from
the lake during the year while over 20% of the nitrogen  was
retained (pages 9 and 10), indicates an underestimation  of phos-
phorus inputs or phosphorus sources discharging directly to  the
lake or to unsampled tributaries.
    While a phosphorus wash-out could have occurred if inputs
had been recently reduced, there is no indication that such a
reduction occurred, and a need for further study of the  phos-
phorus balance of the lake is indicated.
    2.  Non-point sources--Although the sampled tributaries
accounted for over 76% of the total load, the phosphorus export
rates were quite low during the sampling year (page 10).

III.   LAKE WATER QUALITY SUMMARY
      Lake William C. Bowen was sampled three times  during  the open-
  water season of 1972 by means of a pontoon-equipped  Huey  helicopter.
  Each time, samples for physical  and chemical  parameters were collected
  from a number of depths at three stations  on  the lake  (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 first visit, 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 2.1  meters at station 1, 7.0  meters at  station 2,
  and  10.7 meters  at station 3.
      The sampling results are presented in  full  in  Appendix D and
  are  summarized in the following  table.

    2.   Discussion -
            The  control  yield  of  the assay  alga, Selenastrum capri-
        cornutum, indicates  that  the potential primary  productivity
        of the lake was low  at the time  the sample was  collected (03/
        29/73).   The  increase  in  yield with increased levels of phos-
        phorus,  as well  as the lack of increase when only nitrogen
        was added, indicates phosphorus  limitation.
            The  lake  data also  indicate  phosphorus limitation; i.e.,
        the mean inorganic nitrogen/orthophosphorus  ratios were 26/1
        or greater at all sampling times, and phosphorus limitation
        would be expected.

IV.   NUTRIENT LOADINGS
     (See Appendix E for data)
     For the determination of nutrient loadings,  the South Carolina
 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 January when two samples  were collected.  Sampling
 was begun in February, 1973, and was completed in February, 1974.
     Through an interagency agreement, stream flow estimates for the
 year of sampling and a "normalized"  or average year were provided by
 the South Carolina District Office of the  U.S.  Geological Survey for the
 tributary sites nearest the lake.
     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 at stations B-l  and C-l,  in kg/km2/year, and multi-
 plying the means by the II area in km2.
     The operator of the Landrum 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.

        "Permissible"  (oligotrophic loading)          0.38
