                          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 pf 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
     V
    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)3, 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 betv/een 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.  INTRODUCTION
    The Florida Department of Environmental Regulation has recently
published a detailed report on investigations conducted in the Lake
Okeechobee watershed by Department staff and contract investigators
(McCaffrey et al., 1976).   The reader is referred to this  600+ page
report for an in-depth evaluation of the lake and its watershed.
II.  CONCLUSIONS
    A.   Trophic Condition:
            Survey data indicate Lake Okeechobee is eutrophic.   It ranked
        thirteenth when the 41 Florida lakes sampled in 1973 were compared
        using a combination of six water quality parameters*.   Twelve of
        the lakes  had less and one had the same median total  phosphorus,
        four had less median orthophosphorus, 23 had less  median  inorganic
        nitrogen,  11 had less mean chlorophyll  a_, and 24 had greater mean
        Secchi disc transparency.
            Survey limnologists noted water hyacinths at some of  the sam-
        pling stations and abundant emergent and submergent vegetation at
        others.
    B.   Rate-Limiting Nutrient:
            The algal assay results indicate phosphorus limitation at the
        time the sample was collected (03/07/73).  Generally,  the lake data
  See Appendix A.

-------
    indicate phosphorus limitation in March  and  nitrogen  limitation in
    September and November.
C.   Nutrient Controllability:
        1.  Point sources—It  is estimated that  point  sources contributed
    2.5% of the total  load reaching the lake during  the year.   It
    appears that phosphorus  control at the point sources  would  have
    minimal effect on  the water quality of the lake  because of  the
    preponderance of the total  phosphorus load contributed by other
    sources (see discussion  below).
        2.  Non-point  sources—The phosphorus loading  from non-point
    sources is estimated to  have been 97.5%  of the total  load reaching
    the lake.  The Kissimmee River had the largest load of any  of the
    sampled tributaries.  However, this river basin  is impacted
    by point sources in its  northern reaches (i.e.,  Shingle Creek),
    and effects of the point sources are reflected in  high pollutional
    loads (Federico and Brezonik, 1975).
        The other gaged tributaries - Taylor Creek,  Harney Pond Canal,
    Unnamed Creek B-l, Indian  Prairie Canal, Limbin  Creek, and  Unnamed
    Canal L-l - were estimated  to have contributed 11.0%, 7.5%, 5.8%,
    2.1%, 1.6%, and 1.0%, respectively.  Most of the nutrient loads
    in these drainage  areas  are non-point kinds, including dairy farms
    (Taylor Creek) and cattle  grazing (Baldwin,  1975).  Baldwin (op.
    cit.) also indicated that significant amounts of nutrients  are con-
    tributed by sugar cane and vegetable farming activities south and

-------
southeast of the lake.  The importance and effect of these nutrients
on the water quality of Lake Okeechobee is reported by Brezonik
and Federico (1975).
    The ungaged drainage areas, including Nubbin Slough and
the North New River and Hillsboro canals, were estimated to
have contributed over 28% of the total phosphorus load reaching
the lake.  The Nubbin Slough area apparently has much dairy-
farm activity; and, along with the Kissimmee River, appears to
be the most significant source of phosphorus.   The North New
River and Hillsboro canals and the other irrigation canals are
important sources of nutrients when they are back-pumped (Bre-
zonik and Federico, op. cit.).
    Because of the low proportion of direct point-source phos-
phorus contributions, effective control of nutrients will  involve
the agricultural activities in the Kissimmee-Okeechobee watershed,
including dairy farms, grazing, and vegetable  farming (Baldwin,
op. cit.).  Also, nutrient loads in the Kissimmee River basin
could be reduced by control of point-source contributions  in
the Shingle Creek basin (Federico and Brezonik, op. cit.).

IV.    LAKE  WATER  QUALITY SUMMARY
      Lake  Okeechobee was  sampled  three times during 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 ten stations on the lake  (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  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  3.0 meters  at  station  1, 1.2 meters at station 2,
  0.9 meters  at station 3, near-surface at station 4, 3.0 meters at
  station 5,  1.8  meters at station 6, 1.8 meters at station 7, 1.2
  meters at station 8, 1.5 meters  at  station 9, and 1.8 meters at
  station 10.
      The sampling results are presented in full in Appendix D and

    2.  Discussion -

            The control  yields of the assay alga,  Selenastrum capri-

        cornutum, indicate that the potential  primary productivity

        of Lake Okeechobee was low to moderate at  the times  the samples

        were collected.

            There was a  significant increase in yield compared to that

-------
                       10

of the control when only phosphorus was added but a lack of
increase in yield when only nitrogen was added.   These results
indicate phosphorus limitation.
    The mean inorganic nitrogen/orthophosphorus  ratios indicate
a temporal and spatial combination of limiting nutrients (see
tabulation below; the indicated limiting nutrients are in
parentheses).  Generally, the lake was phosphorus limited
in March (the ratio for site 4 is based on a single surface
sample and may not be representative).   The samples taken
during September show a shift to nitrogen limitation,  especially
where large inflows were recorded (e.g., stations 8,  9, and 10).

V.  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.  The drainage areas of the tribu-
taries listed on page 4, representing the sampling stations  indicated
on the map (page v), have been altered by channelization.  The deter-
mination of areas is difficult because of the extensive lowlands and
the characteristic low relief.  The reader is referred to Joyner
(1974) and Davis and Marshall (1975) for information regarding the
delineation and characteristics of Lake Okeechobee drainage basins.
    Surface water drainage from Lake Okeechobee is now controlled by
several  canals, of which St. Lucie, Caloosahatchee, and West Palm
Beach are the most important.  Other canals  serve as both inflow and
outflow channels by means of a closely regulated and complex series
of dams, pumps, and levees (Brezonik and Federico,  1975).  Other known
outflow includes seepage along the southern lake boundary which is estimated
to be between 0.62 and 1.42 m3/sec (Meyer, 1971).
    In this report, nutrient loads for sampled  tributaries were

-------
                                    12
calculated using mean annual concentrations and mean annual  flows.
Nutrient loads for Nubbin Slough and the North New River and Hillsboro
canals are those reported by Davis and Marshall (1975) and are included
in the estimates for the minor tributaries and immediate drainage.
    The incoming or outgoing nutrient loads of the Miami Canal (J-l),
West Palm Beach Canal (K-l), and Unnamed Canal L-l were estimated by
using the mean nutrient concentrations and the mean monthly flow.  The
estimate shown is a result of the summation of each monthly load where a
negative monthly flow represents flow into the lake and a positive  flow
represents flow out of the lake.
    The Miami Canal acts as a phosphorus outflow and a nitrogen inflow
because of its characteristic flow patterns and nutrient concentrations
observed during the sampling year.
    The operator of the Okeechobee wastewater treatment plant provided
monthly effluent samples and corresponding flow data.  The cities of
Clewiston and Belle Glade did not participate, and nutrient loads were
estimated at 1.134 kg P and 3.401 kg N/capita/year.  The Belle Glade
sewage treatment plant discharges into the Hillsboro Canal which is
back pumped into Lake Okeechobee during approximately one-third of  the
year.  Nutrient loads shown for Belle Glade are one-third of the total
estimated.

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 assi-
    milate 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 Okeechobee:
        "Dangerous"   (eutrophic loading)            0.18
        "Permissible"  (oligotrophic loading)       0.09
