                         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 and a report by others (Ketelle and Uttormark,
        1971) Indicate that the Fox Chain of Lakas (Marie,  Grass,  Fox,
        and Plstakee) is eutrophic.  Of the 31 Illinois lakes sampled
        1n 1973, Lake Marie ranked fifteenth, Pistakee Lake ranked
        eighteenth, Grass Lake ranked twentieth, and Fox Lake ranked
        twenty-sixth when compared using a combination of six parameters*.
        1.  Lake Marie - Twelve lakes had less median total  phosphorus,
        16 had less and one had the same median dissolved phosphorus,
        nine had less median inorganic nitrogen, 19 had less mean
        chlorophyll a^, and eight had greater mean Secchi  disc transparency.
        Survey limnologists noted emergent aquatic vegetation at the outlet
        and along the shoreline and observed heavy algal  blooms.   Near-
        depletion of dissolved oxygen occurred with depth at station 1
        in August.  Chlorophyll a. concentrations increased  more  than
        four-fold from the spring to fall sampling along with increased
        numbers of blue-green algae.
        2.  Grass Lake - Twenty-five lakes had less median  total and
        dissolved phosphorus, 14 had less median inorganic  nitrogen.
* See Appendix A.

-------
    27 had less mean chlorophyll a., and 15 had greater mean Secchi
    disc transparency.  Chlorophyll ^concentrations Increased
    more than five-fold from the spring to the summer.
        Survey limnologlsts noted emergent aquatic vegetation along
    much of the shoreline.
    3.  Fox Lake - Twenty-three of the lakes had less median total
    phosphorus, 24 had less median dissolved phosphorus, 11 had
    less median inorganic nitrogen, 25 had less mean chlorophyll  a_,
    and 25 had greater mean Secchi disc transparency.  No surface
    algae or higher aquatic plants were observed by Survey limnolo-
    glsts, but chlorophyll a^ concentrations and numbers of blue-
    green algae increased substantially during the summer.
    4.  Pistakee Lake - Twenty-two lakes had less median total
    phosphorus, 20 had less and one had the same median dissolved
    phosphorus, nine had less and one had the same median inorganic
    nitrogen, 26 had less mean chlorophyll a_, and 23 had greater
    mean Secchi disc transparency.  Survey limnologists did not
    observe any aquatic vegetation; however, chlorophyll a. concen-
    trations increased more than two-fold from the spring to summer
    along with increased numbers of blue-green algae.
B.  Rate-Limiting Nutrient:
        The algal assay results are not considered indicative of
    conditions present in the lakes because of significant nutrient

-------
    losses that occurred in  the  samples during shipment from the
    field to the laboratory.  However, the  lake data indicate that
    all  four lakes were limited  by nitrogen during most of the
    growing season.
C.  Nutrient Controllability:
        1.  Point sources—The mean  annual  contribution from listed
    point sources was 13.3%  of the total  phosphorus input to the Fox
    Chain of Lakes.  The wastewater  treatment plant at Burlington,
    Wisconsin (see map, page vi), and the Fox Lake plant contributed
    an estimated 5.1% and 2.7% of this total, respectively.  The
    Antioch plant contributed  3.1% and the  remaining point sources
    collectively contributed 2.3% of the  total.
        A number of additional point sources discharge to Long Lake
    and to its outlet,  Squaw Creek (see Working Paper No. 309,
    "Report on Long Lake").   To  some extent, these sources con-
    tribute to the total  phosphorus  load  of Squaw Creek as indi-
    cated by the high phosphorus export rate of 92 kg/km2/yr (see
    page 24) and thus contribute to  the Fox Chain of Lakes nutrient
    load.  These point sources are not included in this report
    because of the difficulty  in accurately estimating the portion
    of the phosphorus load retained  in Long Lake and the portion
    contributed to Squaw Creek.  For this reason, the phosphorus
    contribution attributed  to point sources probably is too low.

-------
    The present loading rate of 8.10 g/m2/yr is more than 12
times the rate proposed by Vollenwelder (Vollenweider and
Dillon, 1974) as a eutrophic rate (see page 24).  Although
Vollenweider's model may not be applicable to lakes with
short hydraulic retention times, there is little doubt that
the phosphorus load is excessive as shown by the abundant
growths of macrophytes and blue-green algae.  For this reason,
all phosphorus loads from known point sources should be
minimized to reduce the present rate of eutrophication.  A
100% reduction of the phosphorus from the listed point sources
would reduce the present loading rate to 7.02 g/m2/yr.  Removal
of phosphorus from additional point sources9 such as those
impacting Long Lake, would further reduce the loading rate and
should at least slow the rate of eutrophication now occurring.
In additions the relatively short mean hydraulic retention time
of the Fox Chain of Lakes (23 days) would facilitate water
quality improvement once phosphorus controls have been initiated.
    2.  Non-point sources--Non-point sources accounted for 86.4%
of the total phosphorus load reaching the Fox Chain of Lakes
during the sampling year.  The Fox River contributed 61.6% and
Nippersink Creek contributed 12.8% of the total.  The remaining
tributaries collectively contributed 7.8%,  Ungaged tributaries
were estimated to have contributed 4.0% of the total.

-------
    Sequoit Creek and Squaw Creek had very  high  export rates
of 104 kg and 92 kg P/km2/yr,  respectively.   The Fox River
export rate of 45 kg P/km2/yr  may be  slightly above average.
    The high export rate of Sequoit Creek may be due to unknown
point sources, and the Squaw Creek rate is  influenced by point
sources as discussed above.

III.   LAKE WATER QUALITY SUMMARY
      Marie, Grass, Fox, and Pistakee  lakes were sampled three times during
  the open-water season of 1973 by  means of a pontoon-equipped Huey heli-
  copter.   Each time,  samples for physical and chemical parameters were
  collected from two stations on each  lake and from one 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 phytoplankton identification and enumeration; and during
  the first visit, 18.9-liter depth-integrated samples were 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  in Lake Marie were 6.1 meters at station 1 and 1.2 meters at
  station  2; in Grass  Lake, 0.6 meters at station 1 and 0.6 meters at
  station  2; in Fox Lake,  1.5 meters at station 1 and 4.0 meters at sta-
  tion 2;  and in Pistakee  Lake,  2.1 meters at station 1 and 2.1 meters at
  station  2.

C.  Limiting Nutrient Study:

        The algal assay results for all  four lakes are not considered

    indicative of lake conditions at sampling time (05/09/73)  because

    of substantial nutrient losses in the samples during shipment

    from the field to the laboratory.  However,  the lake data  indicate

    that all four lakes were nitrogen limited during the sampling year

    Nitrogen limitation, as indicated by the algal  assay or by
in-lake nitrogen to phosphorus ratios, does  not necessarily
suggest that the trophic condition of the lake can  be  improved
by controlling nitrogen inputs.  In the majority of cases,
phosphorus is still the element to be controlled.   The apparent
condition of nitrogen-limitation frequently  results from excessive
phosphorus input from point sources and is often accompanied by  a
corresponding increase in primary production.   The  reversal  of the
enriched condition, therefore, depends upon  phosphorus control,
not nitrogen control.

IV.   NUTRIENT LOADINGS
     (See Appendix E  for  data)
     For the determination  of nutrient loadings, the Illinois National
 Guard collected monthly  near-surface grab samples from each of the
 tributary sites indicated  on the maps (pages v and v1), except for the
 high runoff months of March and April when two samples were collected.
 Sampling was begun in June, 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 Illinois 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 nutrient loads,
 in  kg/km2/year, in Nippersink Creek at station 33A-1 and multiplying
 by  the ZZ area  in km2.
     The operators of the Antioch, Hebron Municipal, and Hebron Indus-
 trial  wastewater treatment plants provided monthly effluent samples
 and corresponding flow data.  However, Fox Lake Village, Richmond,
 * See Working  Paper  No.  175.

-------
                                 20
Burlington, and Silver Lake did not participate in  the  sampling program,
and nutrient loads were estimated at 1.134 kg  P and 3.401 kg N/capita/year.
    A number of wastewater treatment plants impact  nearby Long Lake
through discharge to its tributaries.  Therefore, a portion of the Squaw
Creek outlet nutrient loads is contributed by  these point sources and
also enters the Fox Chain of Lakes at Fox Lake. However, it is difficult
to accurately calculate the load due to these  point sources (see Working
Paper No. 309, "Report on Long Lake").   Consequently, the entire nutrient
loads measured in Squaw Creek at station A-l are included as non-point
loads.
    Separate nutrient loadings could not be calculated  for each of the
four lakes in this report because no flow measurements  were provided
for the sampling points between the lakes.  A  total  nutrient load was
calculated for all four lakes however,  and this provides an overall
view of point-source impact on the Fox  Chain of Lakes.

            In the following table, the existing phosphorus  loading
        rates are compared to those proposed by Vollenweider (Vollen-
        weider and Dillon, 1974).  Essentially, his "dangerous"  rate
        is the rate at which the receiving water would become eutrophic
        or remain eutrophic; his "permissible"  rate is that  which would
        result in the receiving water remaining oligotrophic or  becoming
        oligotrophic if morphometry permitted.   A mesotrophic rate 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.
