                          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 fresh water 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(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.

-------
    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.

ACKNOWLEDGMENT

    The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Indiana State Board of
Health for professional involvement, to the Indiana National
Guard for conducting the tributary sampling phase of the Survey,
and to those Indiana wastewater treatment plant operators who
provided effluent samples and flow data.

I.  CONCLUSIONS
    A.  Trophic Condition:
            Survey data indicate that Sylvan Lake is eutrophic.   It  ranked
        eighteenth in overall  trophic quality when the 27  Indiana lakes
        sampled in 1973 were compared using a combination  of six  param-
        eters*.  Twenty-five lakes had less median total phosphorus,  20
        had less median dissolved phosphorus, one had less median inorganic
        nitrogen, 24 had less  mean chlorophyll  a_, and 19 had greater mean
        Secchi disc transparency.  Near-depletion of dissolved oxygen with
        depth occurred at station 2 in October.
            Survey limnologists reported a heavy algal  bloom in progress
        in August.
            The trophic condition of Sylvan Lake appears to have  improved
        somewhat since 1963-64 when it was studied by Wetzel  (1966)  and
        categorized as hypereutrophic and "...one of the most productive
        lakes in the temperate region of the world".   It is likely that
        at least some of the improvement can be attributed to the Indiana
        phosphate detergent ban which became effective in  January, 1972.
    B.  Rate-Limiting Nutrient:
            Because of nutrient changes in the sample,  the algal  assay
        results are not considered indicative of conditions in the lake at
* See Appendix A.

    the time the sample was taken (05/10/73).   The lake data indi-
    cate that Sylvan Lake was nitrogen limited at all  sampling times.
C.  Nutrient Controllability:
        1.  Point sources--The point-source phosphorus contribution
    amounted to 44.3% of the total reaching Sylvan Lake during the
    sampling year.  The City of Kendallville contributed 41.1%,  and
    lakeshore septic tanks were estimated to have contributed 3.1%
    of the total.
        The present phosphorus loading of 1.26 g/m2/yr is just over
    two times that proposed by Vollenweider (Vollenweider and Dillon,
    1974) as a eutrophic loading (see page 12).   Complete removal of
    phosphorus at the Kendallville treatment plant would lower the
    overall loading to 0.74 g/m2/yr.   While this would still  exceed
    the eutrophic loading of 0.62 g/m2/yr, it is likely the reduced
    loading would result in persistent phosphorus limitation and
    improvement in the trophic condition of the lake.
        2.  Non-point sources—Over 55% of the total phosphorus  input
    to Sylvan Lake was contributed by non-point sources during the
    sampling year.  The Henderson Lake Ditch contributed 37.5%;  Oviatt
    Ditch, 10.7%;  and the Latta Lake outlet contributed 1.9% of the
    total.  Ungaged tributaries were estimated to have contributed 4.3%
    of the total phosphorus input.
        The phosphorus export rates of the Sylvan Lake tributaries com-

III.   LAKE WATER QUALITY SUMMARY
      Sylvan Lake was sampled three times  during  the  open-water  season
  of 1973 by means of a pontoon-equipped Huey helicopter.   Each  time,
  samples for physical  and chemical  parameters were collected  from a
  number of depths at two 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 second 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 3.0
  meters at station 1  and 5.5 meters at station 2.
      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 indicative of
    conditions in the lake at the time of sampling because  of sig-
    nificant changes in nutrient concentrations  in the  sample
    between the field and the laboratory.   The lake data  indicate
    nitrogen limitation; the mean inorganic m'trogen/orthophosphorus
    ratios were 12/1 or less at all sampling stations and times.

-------
IV.   NUTRIENT LOADINGS
     (See Appendix E for data)
     For the determination  of nutrient loadings,  the  Indiana 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 February when  two samples  were collected.  Sampling
 was begun in June,  1973, and was  completed in May, 1974.
     Through an interagency agreement,  stream flow  estimates for the
 year of sampling and a  "normalized"  or average year  were provided by
 the Indiana 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" ("ZZ" of  U.S.G.S.) were estimated using  the means of  the
 nutrient loads at stations B-l  and D-l,  in kg/km2/year, and multi-  •
 plying the means by the ZZ area in km2.
     The operator of the Kendallville wastewater  treatment plant pro-
 vided monthly effluent  samples  and corresponding flow data.
     Estimated phosphorus loads  were  reduced by 50% to adjust for the
 phosphate detergent limitation  in effect in Indiana  since January, 1972.
 * See Working  Paper  No.  175.

    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.
                                  Total Phosphorus       Total Nitrogen
        	Total   Accumulated    Total   Accumulated
        grams/m2/yr             1.26       loss*       44.6       18.2

        Vollenweider phosphorus loadings
         (g/m2/yr) based on mean depth and mean
         hydraulic retention time of Sylvan Lake:
            "Dangerous"  (eutrophic loading)              0.62
            "Permissible"  (oligotrophic loading)          0.31
* There was an apparent loss of phosphorus during the sampling year.   This
  may have been due to solubilization of previously sedimented phosphorus,
  recharge with phosphorus-rich ground water, or unknown and unsampled
  point sources discharging directly to the lake or to one of the ungaged
  tributaries.
