                         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.

ACKNOWLEDGMENT

    The staff of the National Eutrophicatlon Survey (Office of
Research & Development, U. S. Environmental  Protection Agency)

I.  CONCLUSIONS
    A.  Trophic Condition:
            Survey data show that Crab Orchard Lake Is eutrophic.   It
        ranked eighth in overall trophic quality when the 31  Illinois
        lakes sampled in 1973 were compared using a combination of six
        lake parameters*.  Ten of the lakes had less median total  phos-
        phorus, four had less and one had the same median dissolved
        phosphorus, two had less and one had the same median  inorganic
        nitrogen, 24 had less mean chlorophyll a_, and 17 had  greater
        mean Secchi disc transparency.  Marked depression of  dissolved
        oxygen with depth occurred at sampling station 1 in August,
        1973.
            Survey limnologists reported a blue-green algal bloom  in
        progress in August and noted the occurrence of submergent  and
        emergent aquatic macrophytes in the shoreline shallows  near
        all three sampling stations.
    B.  Rate-Limiting Nutrient:
            A significant change in primary nutrients occurred  in  the
        assay sample between the time of collection and the beginning
        of the assay, and the results are not representative  of condi-
        tions in the lake at the time the sample was taken (05/08/73).
* See Appendix A.

-------
        The lake data indicate phosphorus limitation  in May but
    nitrogen limitation in August and October.
C.  Nutrient Controllability:
        1.  Point sources—The estimated phosphorus contribution
    of point sources amounted  to 26.3% of the total load reaching
    the lake during the sampling year.  The City  of Marion was
    estimated to have contributed 20.3% and the other four point
    sources 6.0% of the total  load.
        The Crab Orchard National Wildlife Refuge provides a winter-
    ing area for a large segment of  the Mississippi flyway Canada
    goose flock as well  as many flyway ducks, and it  is estimated
    that ducks and geese contributed 7.9% of the  total phosphorus
    load to Crab Orchard Lake  during the sampling year (see page
    10).
        The present phosphorus loading rate of 2.82 g/m2/yr is over
    seven times that proposed  by Vollenweider (Vollenweider and
    Dillon, 1974) as a eutrophic rate (see page 14).  Even complete
    removal of phosphorus at the point sources would  only reduce
    the loading rate to 2.07 g/m2/yr (still  over  five times the
    dangerous rate).  However, Crab  Orchard Lake  is phosphorus
    limited part of the time,  and it is likely that a high degree
    of phosphorus control at the point sources would  result in

-------
persistent phosphorus limitation and a reduction in  the
Incidence and severity of nuisance algal  blooms, particularly
if a significant portion of the phosphorus export of Crab
Orchard Creek proves to be controllable (see below).
    2.  Non-point sources—It is estimated that non-point
sources accounted for 65.8% of the total  phosphorus  load
reaching Crab Orchard Lake during the sampling year.   However,
Crab Orchard Creek had a very high phosphorus export rate of
221 kg/km2/yr (see page 14).
    It 1s unlikely that the high rate resulted solely from
underestimation of the phosphorus loads from the City of
Marion and the Crab Orchard School; e.g.,  the phosphorus
load for Marion would have to be nearly three times  greater
than the estimated load to lower the Crab  Orchard Creek
export rate to that of Wolf Creek (16 kg/km2/yr).  Therefore,
it appears that either there are other point sources  in the
Crab Orchard Creek drainage or land-use practices result  in
an unusually high phosphorus export.  In either case,  a heed
for further study of the drainage is indicated.

III.   LAKE  WATER QUALITY  SUMMARY
      Crab  Orchard  Lake 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 usually 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 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 6.1 meters at station 1, 3.0 meters at sta-
  tion 2, and 1.2 meters  at  station 3.
      The lake sampling results are presented in full in Appendix D and
  are summarized in the following table.

C.  Limiting Nutrient Study:
        A 15% loss of inorganic nitrogen and a 150% gain in  ortho-
    phosphorus occurred in the assay sample between the time of
    collection and the beginning of the assay, and the limiting
    nutrient was shifted from phosphorus in the lake (the mean
    inorganic nitrogen/orthophosphorus ratio was 17/1) to nitrogen
    limitation in the assay sample (N/P = 6/1).  Consequently,  the
    assay results are not representative of conditions in the lake
    at the time the sample was taken (05/08/73).
        As noted above, the lake data indicate phosphorus limitation
    in May; however, nitrogen limitation is indicated in August (N/P
    8/1) and October (N/P = 9/1).

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 map  (page v), except for the high
 runoff months of February  and  March when two samples were collected.
 Sampling was begun in June,  1973,  and  was  completed  in May, 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*.
     Except for Pin Oak Creek and Pigeon Creek, nutrient loads shown
 are those measured minus point-source  loads, 1f any.  However, the
 combined estimated nutrient  loads  for  Carterville and Crainville
 exceeded those measured in Pin  Oak Creek,  and the estimated Refuge
 Headquarters loads exceeded  the loads  measured in Pigeon Creek.
 Therefore, the background  loads for these  two streams were estimated
 using the nutrient loads,  in. kg/km2/yr, in Wolf Creek at station C-l
 and multiplying by the Pin Oak  Creek and Pigeon Creek drainage areas
 in km2.
 *  See  Working  Paper No. 175.

-------
                                 10
    Nutrient loadings for unsampled "minor tributaries and Immediate
drainage" ("ZZ" of U.S.G.S.) were estimated using the nutrient loads,
in kg/km2/year, at station C-l and multiplying by the ZZ area  in  km2.
    The City of Marion, the villages of Carterville and Crainville, and
the Crab Orchard School did not participate in the sampling program,
and nutrient loads were estimated at 1.134 kg P and 3.401 kg N/capita/
year.
    Estimates of nutrient contributions by wild ducks and geese
utilizing Crab Orchard National Wildlife Refuge were based on  50,000
over-wintering geese reported by the Fish and Wildlife Service
(Anonymous, 1969) and the following assumptions:
    1.  One-half as many ducks as geese over-winter.
    2.  Winter resident waterfowl are at the lake for
        five months.
    3.  Each wild duck contributes 0.20 kg total phosphorus
        and 0.45 kg total nitrogen per year (Paloumpis and
        Starrett, 1960).
    4.  Each wild goose contributes the same amount of
        phosphorus and nitrogen as one wild duck since
        geese typically feed in fields away from the
        lake several hours each day.

        2.  Industrial  - In 1969,  some  26  firms  in the Crab Orchard Lake
        drainage produce hardware  for the  space  program, explosives, office
        supplies, chemicals, solvents,  and a variety of other products
        (Anonymous, 1969).   The current status and nutrient significance
        of these industries is  not known.

    E.  Yearly Loading Rates:
            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 1s that which would
        result in the receiving water remaining ollgotrophic 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.

        Vollenweider loading rates for phosphorus
         (g/m2/yr) based on mean depth and mean
         hydraulic retention time of Crab Orchard Lake:
            "Dangerous"  (eutrophic rate)       0.38
            "Permissible"  (oligotrophic rate)  0.19
* Unusually high export rate probably is indicative of unmeasured  point-source
  influence.
