                         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(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.

-------
                                 111
    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 that Indian Lake is eutrophic.   It
        ranked eleventh in overall trophic quality when the 20 Ohio
        lakes sampled in 1973 were compared using a combination of
        six parameters*.  Eleven lakes had less median total  phos-
        phorus, nine had less median dissolved phosphorus, four had
        less and one had the same median inorganic nitrogen,  16 had
        less mean chlorophyll a_, and 15  had greater Secchi disc trans-
        parency.  Depression of dissolved oxygen with depth occurred
        at station 3 in October.
            Survey limnologists reported an algal bloom in October
        and noted that macrophytes were  common in the shallow areas
        near shore.
             y
    B.  Rate-Limiting Nutrient:
            The algal assay results indicate that Indian Lake was phos-
        phorus limited at the time the sample was collected (05/04/73).
        The lake data indicate phosphorus limitation in May and August
        as well, but nitrogen limitation in October.
    C.  Nutrient Controllability:
            1.  Point sources—No municipal or industrial  wastewater
* See Appendix A.

                             2
treatment plants impacted Indian Lake during the sampling year,
and the mean estimated phosphorus contribution of shoreline
septic tanks amounted to only 4.2% of the total  load  reaching
Indian Lake during the sampling year.  However,  recent Ohio
Environmental Protection Agency investigations indicate major
pollution problems at the lake are over-development and by-
passing of sewage during wet periods when the capacity of sewer
lines is exceeded (Youger, 1975).  Therefore, it is likely that
the estimation of septic tank phosphorus contributions is much
too low.
    The calculated phosphorus loading of 0.28 g/m2/yr is less
than that proposed by Vollenweider (Vollenweider and  Dillon, 1974)
as a eutrophic loading (see page 12).  However,  in view of the
trophic condition of the lake and the problems associated with
over-development noted above, it is probable that the actual load-
ing is much higher than that indicated, and a need for a more-
detailed study of the lake is indicated.
    It is noted that an apparent phosphorus loss from the  lake
occurred during the sampling year (see page 10).  It is likely
that the "loss" resulted from underestimation of the shoreline
septic tank loads and solubilization of previously sedimented
phosphorus during the almost continuous dredging required  to
maintain satisfactory depths in the lake (Youger, op. cit.)
    2.  Non-point sources—About 94% of the total phosphorus
input to Indian Lake is attributed to non-point sources.  The
North Fork Miami River contributed 25.5% of the total, and  the

-------
                                     3
        South Fork Miami River contributed 38.0%.  Ungaged tributaries
        and immediate drainage were estimated to have contributed 26.1%
        of the total load.
            The phosphorus export rates of the Indian Lake tributaries
        were relatively low.  The North Fork rate was 34 kg/km2/yr, and
        the South Fork rate was 20 kg/km2/yr (see page 11).   These rates
        compare well with the 49 kg/km2/yr rate of Loramie Creek, a
        tributary of nearby Lake Loramie*.

III.   LAKE WATER QUALITY SUMMARY
      Indian 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
  three stations on the  lake  and from  one  or more depths  at each station
  (see map,  page v).   During  each visit, a single depth-integrated  (near
  bottom to  surface) sample was  composited from the stations for phyto-
  plankton 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 1.5 meters at  station 1, 0.9 meters at  station 2,  and
  3.0 meters at  station  3.
      The  lake 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-
        corniLtum, indicates that the potential  primary  productivity
        of Indian Lake was moderately high at the time  the sample
        was collected (05/04/73).  The addition  of phosphorus alone
        produced a significant increase in yield  over that of the
        control  which indicates phosphorus limitation (note that
        addition of nitrogen alone produced a yield which was not
        significantly greater than that of the control).
            The lake data also indicate limitation by phosphorus in
        May and August (the mean inorganic nitrogen/orthophosphorus
        ratios were 17/1 or greater at all stations).  However,
        nitrogen limitation is indicated in October; i.e., the mean
        N/P ratios were 5/1 or less at all stations, and  nitrogen
        limitation would be expected.

IV.   NUTRIENT LOADINGS
     (See Appendix E for data)
     For the determination of nutrient loadings,  the Ohio 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 March when three samples were collected.   Sampling
 was begun in May, 1973, and was  completed  in April, 1974.
     Through an interagency agreement, stream flow  estimates for the
 year of sampling and a "normalized" or average year were provided by
 the Ohio District Office of the  U.S.  Geological  Survey for the tribu-
 tary sites nearest the lake.
     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
 drainage" ("ZZ" of U.S.G.S.) were estimated using  the nutrient loads,
 in  kg/km2/year, at station D-l and multiplying by  the ZZ area in km2.
     No municipal or industrial wastewater  treatment plants impacted
 Indian Lake during the sampling  year.

        Yearly Loadings:
            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 oligo-
        trophic if morphometry permitted.  A mesotrophic 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)  0.17
* There was an apparent loss of phosphorus during the sampling year.   This
  may have been due to underestimation of the phosphorus loads from shore-
  line septic tanks, phosphorus release from the sediments during dredging,
  or both.
