                         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.

-------
                                 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 Dillon Reservoir is eutrophic.
        It ranked eighteenth in overall trophic quality when  the 20
        Ohio lakes sampled in 1973 were compared using a combination  of
        six parameters*.  Sixteen of the lakes had less median total
        phosphorus, 18 had less median dissolved phosphours,  13 had
        less median inorganic nitrogen, eight had less mean chlorophyll
        a., and 11 had greater mean Secchi  disc transparency.   Marked
        depression of dissolved oxygen with depth occurred at sampling
        station 1 in July and October.
            Survey limnologists noted sumberged vegetation at station 1
        in October and an algal bloom along the shoreline at station  3
        in April.
    B.  Rate-Limiting Nutrient:
            The algal assay results indicate that Dillon Reservoir was
        phosphorus limited at the time the sample was collected (04/26/73),
        The reservoir data indicate phosphorus limitation at all sampling
        times.
    C.  Nutrient Controllability:
            1.  Point sources—The phosphorus contribution of known
        point sources amounted to about 41% of the total input to Dillon
        Reservoir during the sampling year.  Newark contributed 21.5%;
* See Appendix A.

-------
                             2
Heath, 4.435; Buckeye Lake SD, 4.3%; Johnstown, 2.7%;  Granville,
2.5%; Utica, 1.3%; Patalaska, 1.1%; Hebron, 1.1%; and seven other
domestic sources collectively contributed 1.8%.
    The present phosphorus loading of 32.91 g/m2/yr is over 15
times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 15).  However, Vollenweider's
model may not be applicable to water bodies with short hydraulic
retention times, and the mean hydraulic retention time of Dillon
Reservoir is a short nine days.  Nonetheless, the existing trophic
condition of the reservoir is evidence of excessive nutrient loads.
    While even a 100% reduction in the phosphorus loads from the
known point sources would still leave a loading  of 19.51  g/m2/yr,
the reservoir is phosphorus limited, and all phosphorus inputs
should be minimized to the greatest practicable  extent to slow the
eutrophication of Dillon Reservoir.
    2.  Non-point sources—About 59% of the total phosphorus input
to Dillon Reservoir during the sampling year is  attributed to  non-
point sources.  After accounting for the known point sources,  the
Licking River contributed 56.4% of the total. The remaining sampled
tributaries collectively contributed 1.5% of the total phosphorus
load.  The contribution of ungaged tributaries was estimated to
have been 1.3% of the total.
    The phosphorus export rate of the Licking River was substantially
higher than the rates of the other tributaries sampled (see page 14).
It is likely that municipal point sources beyond the 40-kilometer

        limit of the Survey* or industrial point sources (see page 11)
        contributed significantly to the phosphorus load in the river.

III.   LAKE WATER QUALITY SUMMARY
      Dillon 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
  one or more depths at two stations  during  the summer  and from three
  stations during the spring and fall  (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
                                       f
  chlorophyll a_ analysis.  The maximum depths sampled were 7.6 meters at
  station 1, 3.0 meters at  station 2,  and 2.1 meters at station 3.
      The lake sampling results are presented in full in Appendix D and
  are summarized in the following table.

    3.   Discussion -
            The control  yields of the assay alga,  Selenastrum cajpri-
        cornutum,  indicate that the potential  primary  productivity
        of Dillon  Reservoir was high at the time  the sample was col-
        lected (04/26/73).  The addition of phosphorus alone produced
        a significant increase in yield in  both assays which indicates
        limitation by phosphorus.  Note that in neither assay did the
        addition of nitrogen alone result in a yield significantly
        different  than that of the control.
            The reservoir data also indicate phosphorus limitation.
        At all  sampling  stations and times,  the mean inorganic nitrogen/
        orthophosphorus  ratios were 23/1  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 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"  ("II"  of  U.S.G.S.) were estimated using the means of the
 nutrient exports, in  kg/km2/year, at  stations B-l, C-l, E-l, and F^-l
 and  multiplying  the means  by the II area in km2.
     The operators of  the Newark and Pataskala wastewater treatment
 plants  provided  monthly  effluent samples and corresponding flow data.
 The  operators  of the  Granville, Utica, Heath, Hebron, Dillon State Park
 #1 and  #2,  and the  Lake  and Hills Sewer District wastewater treatment
 plants  did  not participate  in the sampling  program, and nutrient loads
 were estimated at 1.134  kg  P and 3.401 kg N/capita/year.

Nutrient  loads  from  the wastewater treatment plants at Buckeye Lake

SD#1, Forest Hills Subdivision #2, Jardin Manor Subdivision, Johnstown,

Licking County  Home,  and  the Miller  Company were calculated using daily

loads provided  by the  Ohio  Environmental Protection Agency (Youger, 1975);

however,  nitrogen loads shown for these sources are total Kjeldahl  nitrogen

only.

E.  Yearly Loading Rates:
        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.
