                          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 freshv/ater 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 freshv/ater 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 bnsin is
documented.  The report is fornvattcd to provide state environmental
agencies with specific information for basin planning [§303(e)], water
quality criteria/standards review [§303(c)]>  clean lakes [S314(a,b)~J,
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 betv/een 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 Eutroplvication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Florida Department of Environ-
mental Regulation for professional involvement and to the Florida
National Guard for conducting the tributary sampling phase of the
Survey.

    Joseph W.  Landers, Jr., Secretary of the Department of Environ-
mental Regulation; John A Redmond, fbrnter Director of the Division
of Planning, Technical Assistance, and Grants; and Dr. Tim S.  Stuart,
Chi'••' of the Bureau of Water Quality, provided invaluable lake docu-
mentation and counsel  during the survey, reviewed the preliminary
reports, and provided critiques most useful in the preparation of this
Working Paper series.

    Major General  Henry W. McMillan (Retired), then the Adjutant
General of Florida, and Project Officer Colonel  Hugo F.  Windham,
who directed the volunteer efforts of the Florida National Guard,
are also gratefully acknowledged for their assistance to the Survey.

 I.   INTRODUCTION
     South Lake was included in the National  Eutrophication  Survey  as  a
 water body of interest to the Florida Department of Environmental  Regu-
 lation.   Tributaries and nutrient sources were not sampled,  and  this
 report relates only to the lake sampling data.
     South Lake was surveyed by the Florida Game and Freshwater Fish
 Commission from 1966 to 1973 (Dingell-Johnson projects,  1966-1973).
II.   CONCLUSIONS
     A.   Trophic Condition:
             Survey data indicate that South Lake is eutrophic.   It ranked
         twelfth when the 41 Florida lakes sampled in 1973 were compared
         using an index of six parameters*.  Fifteen of the  lakes had  less
         median total phosphorus, 17 had  less and one had the same  median
         orthophosphorus, 11 had less and two had the same median
         inorganic nitrogen, 13 had less  mean chlorophyll  a.,  and  12 had
         greater and one had the same mean Secchi disc transparency.
             Survey limnologists noted floating and submerged aquatic  vege-
         tation at all  sampling times.
     B.   Rate-Limi ting Nutrient:
             The algal  assay results indicate nitrogen limitation at the
         time the sample was collected (03/15/73).   The lake  data indicate
         nitrogen limitation at all  sampling times.

IV.   WATER QUALITY SUMMARY
     South Lake was sampled three times  in  1973  by means of a pontoon-
 equipped Huey helicopter.   Each time, a near-surface  sample for
 physical and chemical  parameters was  collected  from one station
 on  the lake (see map,  page v).   During  each  visit,  a  single depth-
 integrated (near bottom to surface) sample was  collected  for phyto-
 plankton identification and enumeration; and a  similar sample was
 collected for chlorophyll  a_ analysis.   During the first visit, a
 single 18.9-liter surface sample was  taken for  algal  assays.
     The sampling results are presented  in  full  in Appendix C 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 South Lake was high at the  time the sample was collected.
        A significant increase in yield occurred  with the addition
        of nitrogen alone, but the addition of phosphorus alone did
        not result in a significant difference in yield as compared
        to that of the control.   Therefore, nitrogen limitation would
        be expected.
            The lake data also indicate nitrogen  limitation.  The
        inorganic nitrogen to orthophosphorus  ratios were 9 to 1
        or less at all sampling times.
