                         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)j, 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.

-------
                                 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 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:
            The Survey data indicate that Tappan Reservoir is eutrophic.
        It ranked sixth in overall trophic quality when the 20 Ohio lakes
        sampled in 1973 were compared using a combination of six parameters*.
        Two lakes had less and one had the same median total phosphorus,
        three had less median dissolved phosphorus, three had less median
        inorganic nitrogen, ten had less mean chlorophyll a^, and six had
        greater mean Secchi disc transparency.  Dissolved oxygen was depleted
        at the 6.4 meter depth at station 1 in July.
            Survey limnologists reported surface algal blooms in July and
        October.
    B.  Rate-Limiting Nutrient:
            The algal assay results indicate that Tappan Reservoir was
        phosphorus limited when the sample was collected (04/21/73).  This
        finding is substantiated by the lake data which show mean inorganic
        nitrogen to orthophosphorus ratios of 23 to 1  or greater at all
        sampling times.
    C.  Nutrient Controllability:
            1.  Point sources—The estimated total phosphorus contribution
        from septic tanks amounted to 1.3/6 of the total load.  The present
        loading of 0.29 g/m2/yr is less than that proposed by Vollenweider
* See Appendix A.

         (Vollenweider and  Dillon, 1974) as a eutrophic loading (see
         page 11).  Nonetheless, the reservoir 1s eutrophic, and phosphorus
         inputs should be minimized to the greatest practicable degree.
            2.  Non-point  sources—About 99% of the total annual  phos-
         phorus input to Tappan Reservoir is attributable to non-point
         sources.  Ungaged  tributaries accounted for an estimated 44.3%
         of the total input.  The other non-point sources are Clear Fork
         (23.1%), Standingstone Fork (20.2%), and Beaverdam Run (5.0%).
            The phosphorus export rates of the sampled streams were quite
         low during the Survey sampling year (see page 10) and compare
         well with the mean export rate of the six Berlin Reservoir*
         tributaries (26 g/km2/yr).

III.   LAKE WATER QUALITY SUMMARY
      Tappan Reservoir 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 two  or more depths at each station  (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 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 7.0
  meters at station 1, 4.6 meters at station 2, and  1.8  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-
        cornutum, indicates that the potential  primary  productivity
        of Tappan Reservoir was moderate at the time the sample was
        collected (04/21/73).  The addition of phosphorus alone pro-
        duced a significant increase in yield,  whereas  no such increase
        was seen with the addition of nitrogen alone.  Therefore,
        phosphorus limitation is indicated.
            The lake data substantiate this conclusion.   At all
        sampling times, the mean inorganic nitrogen to  orthophosphorus
        ratios were  23 to 1 or greater.

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 months of February and March  when two  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
 tributary 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 means of the
 nutrient loads, in kg/km2/year,  at stations A-l, B-l, and  D-l and
 multiplying the means by the ZZ area  in km2.
     There are no known municipal waste treatment plants impacting
 Tappan Reservoir.

    E.  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.
                                  Total Phosphorus       Total Nitrogen
        	Total   Accumulated    Total   Accumulated
        grams/mVyr             0.29       loss*       9.3       loss*
        Vollenweider phosphorus loadings
         (g/m2/yi") based on mean depth and mean
         hydraulic retention time of Tappan Reservoir:
            "Dangerous"  {eutrophic loading)        0.52
            "Permissible"  (oligotrophic loading)   0.26
* There was an apparent loss of nutrients during the sampling year.   This  may
  have been due to nitrogen fixation in the lake, solubilization  of  previously
  sedimented nutrients, recharge with nutrient-rich ground water, unknown  and
  unsampled point sources discharging directly to the lake, or underestimation
  of the nutrient loads from ungaged tributaries.  By trimming the August  and
  September total phosphorus concentrations at the outlet, which  appear to be
  higher than normal, the outlet phosphorus loading is reduced to 2,330 kg/yr
  and a net accumulation of 1,080 kg/yr is seen.  Doing the same  for total
  nitrogen gives outlet N of 85,250 kg/yr and net accumulation of 28,935 kg/yr.
