                          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 freshwater 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.

-------
                                    m
    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

I.  CONCLUSIONS
    A.  Trophic Condition:
            Survey data indicate Lake Monroe is eutrophic.  It ranked
        twenty-ninth in overall trophic quality when the 41 Florida
        lakes sampled in 1973 were compared using a combination of six
        parameters*.  Twenty-five of the lakes had less median total
        phosphorus, 27 had less median dissolved phosphorus, 34 had less
        median inorganic nitrogen, ten had less mean chlorophyll  a^, and
        29 had greater mean Secchi disc transparency.
            Survey limnologists observed beds of macrophytes near the
        shore at sampling station 1 in March and at all three stations
        in September and November.
            Brezonik et al. (in prep.) have reported improved water quality
        in Lake Monroe during periods of high flow in the St.  Johns
        River.  Two of the three Survey lake sampling visits were made
        during such periods, so data obtained during those visits may not
        be representative of normal conditions.
    B.  Rate-Limiting Nutrient:
            The algal assay results indicate Lake Monroe was nitrogen limited
        at the time the sample was collected (11/05/73).  The lake data indi-
        cate nitrogen limitation at all sampling stations and times.

C.  Nutrient Controllability:
        1.  Point sources—During the sampling year,  Lake Monroe
    received a total phosphorus loading about nine times that
    proposed by Vollenweider (Vollenweider and Dillon,  1974)  as
    a eutrophic loading (see page 13).  However,  Vollenweider's
    model probably does not apply to water bodies with  short
    hydraulic retention times,  and the mean hydraulic retention
    time of Lake Monroe is only 10 days.
        It is estimated that the wastewater treatment plants  con-
    sidered in this report contributed only about 6%  of the total
    phosphorus and 1.5% of the total nitrogen inputs  to the lake
    during the sampling year; and, regardless of the  applicability
    of Vollenweider's model, elimination of phosphorus  from these
    two plants alone probably would not result in a significant
    improvement in the trophic condition of the lake.
        However, since some of the nutrient loading to  the St.  Johns
    River is contributed by sewage treatment plants discharging
    to the river upstream from Lake Monroe, to Lake Jessup, and to
    the Econlockhatchee River,  advanced waste treatment or effluent
    diversion at all of these plants might slow the eutrophication
    of Lake Monro, but a more intensive study of the  impact of  the
    distant point sources is needed to determine the  effect of  overall
    point-source nutrient control.

-------
                             3
    2.   Non-point sources—The St.  Johns River is the primary
source of nutrient loading to Lake Monroe and contributed about
91% of the total  phosphorus load and 97% of the total nitrogen
load to the lake during the sampling year.  Much of the nutrient
loading to the river results from use of the floodplain as pasture
during the annual dry season.

III.   WATER QUALITY SUMMARY
      Lake Monroe was sampled three times  in 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 phytoplankton identification and enumeration;  and
  during the third 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 2.7 meters at  station  1,
  1.8 meters at station 2,  and  3.4 meters  at station 3.
      The 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 capri-

        cornutum, indicate that the potential  primary productivity

        of Lake Monroe was high at the time the assay sample was

        collected (11/05/73).  The addition of nitrogen alone or  in

        combination with orthophosphorus significantly increased

        yields while addition of orthophosphorus alone did not.

        This indicates nitrogen limitation.

            The lake data indicate nitrogen limitation at all  sampling

        times; i.e., the mean inorganic nitrogen/orthophosphorus

        ratios were 4/1 or less at all sampling times and stations.

IV.   NUTRIENT LOADINGS
     (See Appendix E for  data)
     For the determination  of nutrient  loadings,  the  Florida National
 Guard collected monthly  near-surface grab  samples  from each of the
 tributary sites indicated  on the  map (page v).   Sampling was begun in
 March,  1973, and was completed in February,  1974.
     Through an interagency agreement,  stream flow  estimates for the
 year of sampling and a  "normalized" or average year  were provided by
 the Florida 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 summarized from  Brezonik et al. (in
 prep.).
     The operator of the  Deltona wastewater treatment plant provided monthly
 effluent samples and corresponding flow data.  The operator of the Sanford
 wastewater treatment plant did not participate in  the Survey; nutrient
 loads from this source were estimated  at 1.134 kg  P  and 3.401 N/capita/year,
 and flows were estimated at 0.3785 m3/capita/day.

    E.  Yearly Loads:
            In the following table, the existing phosphorus loadings
        are compared to those proposed by Vollenweider (Vollenweider
        and Dillon, 1974).  Note, however, that Florida lakes may be
        able to assimilate phosphorus at a somewhat higher level  than
        that suggested by Vollenweider (Shannon and Brezonik, 1972).
            Essentially, Vollenweider's "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".
            Vollenweider's model may not be applicable to water bodies
        with short hydraulic retention times.
                                  Total Phosphorus        Total Nitrogen

        Vollenweider phosphorus loadings
         (g/m2/yr) based on mean depth and mean
         hydraulic retention time of Lake Monroe:
            "Dangerous"  (eutrophic loading)           1.54
            "Permissible"  (oligotrophic loading)       0.77
* There was an apparent loss of nutrients during the sampling year.   This
  may have been due to nutrient fixation in the lake, solubilization of
  previously sedimented nutrients,  unknown and unsampled point sources
  discharging directly to the lake, underestimation of the minor tributary
  and immediate drainage load, or (probably) insufficient sampling in rela-
  tion to the short hydraulic retention time of the lake.
