    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)j,
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

    The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Michigan Department of
Natural Resources for professional involvement and to the
Michigan National Guard for conducting the tributary sampling
phase of the Survey.

I.  CONCLUSIONS



    A.  Trophic Condition:



            Survey data and the records of others (Anonymous, 1972a)



        show that Lake Allegan is eutrophic.  Of the 35 Michigan lakes



        sampled in November when essentially all were well-mixed, 27



        had less mean total phosphorus, 24 had less mean dissolved



        phosphorus, and 23 had less mean inorganic nitrogen; of all



        41 Michigan lakes sampled, 32 had greater Secchi disc transpar-



        ency, and 24 had less mean chlorophyll a*.



            Survey limnologists observed that Lake Allegan  was very turbid



        and had a high concentration of suspended particulate matter.  They



        noted the presence of rooted aquatic vegetation in  the shallows



        and reported a rather heavy blue-green algal bloom  in September,



        1972.



    B.  Rate-Limiting Nutrient:



            There was a significant loss of phosphorus in the algal  assay



        sample, and the results are not representative of conditions in



        the lake at the time the sample was collected.



            The lake data indicate nitrogen limitation in June but phos-



        phorus limitation in September and November.
* See Appendix A.

-------
    C.  Nutrient Controllability:
            1.  Point sources—During the sampling year, Lake Allegan
        received a total phosphorus load at a rate over 12 times
        that proposed by Vollenweider (in press) as "dangerous";  i.e.,
        12 times the eutrophic rate (see page 13).  While it is  likely
        that Vollenweider's model is not applicable to water bodies
        with such a short hydraulic retention time, the existing  tro-
        phic condition of Lake Allegan is evidence of excessive  nu-
        trient loads.
            It is calculated that the municipal  point sources included
        in this study contributed about 23% of the total phosphorus
        load.  While even complete removal  of phosphorus at these
        sources would still leave a loading rate of about 215 Ibs/acre/
                    2
        yr or 24 g/m /yr (i.e., about nine times the eutrophic rate),
        in view of the very short hydraulic retention time, and  the
        questionable applicability of Vollenweider's model, it is
        likely that a high degree of phosphorus removal at the munici-
        pal sources would at least reduce the incidence and intensity
        of nuisance algal blooms in Lake Allegan.
            Now, it is known that there were unsampled point sources of
        nutrients in the Lake Allegan drainage (Knight and Lauff, 1969)
        beyond the 25-mile Timit of the Survey*; and assuming the mean
* See Working Paper No. 1, "Survey Methods, 1972".

-------
annual nutrient exports of Dumont Creek (page 12) are typical
of non-point contributions in the drainage, it is calculated
that the unsampled point sources contributed about 253,000
pounds of phosphorus and 729,000 pounds of nitrogen to the
Kalamazoo River drainage (at station A-2 and thence to Lake
Allegan) during the sampling year.
    To effect a marked improvement in the trophic condition of
Lake Allegan, it appears that control of phosphorus at all of
the sampled and unsampled point sources will be necessary, and
it is calculated that an overall 80% reduction of the point
source load would reduce the loading rate to just over 11  g/
 2
m /yr, or less than five times Vollenweider's eutrophic rate.
    2.  Non-point sources (page 12)--During the sampling year,
the phosphorus export of the Kalamazoo River was nearly four
times that of Dumont Creek and is evidence of the significance
of the unsampled point sources noted above.
    In all, it is calculated that "non-point" sources con-r
tributed nearly 77% of the total phosphorus load to Lake
Allegan during the sampling year.

III.   LAKE AND DRAINAGE BASIN  CHARACTERISTICS



      Lake Allegan was  sampled three  times  during  the  open-water  season



  of  1972 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



  (near bottom to surface) sample was composited from  the  stations for



  phytoplankton identification and enumeration; and  during the second



  visit,  a single five-gallon  depth-integrated sample  was  composited for



  algal  assays.  Also each time, depth-integrated  samples  were collected



  from each of the stations for chlorophyll  a_ analysis.  The maximum



  depths  sampled  were 8 feet at station  1,  6 feet  at station 2, and  20



  feet at station 3.



      The results obtained are presented  in  full in  Appendix C, and  the



  data for the fall sampling period,  when the  lake essentially was well-



  mixed,  are summarized below.  Note, however, the Secchi  disc summary



  is  based on all  values.

  times,  refer to Appendix C.

C.  Limiting Nutrient Study:

        There was a loss of about 64% of the dissolved phosphorus

    in the algal assay sample from the time of collection to the

    beginning of the assay, and the results are not representative

    of conditions in the lake at the time the sample was taken.

        The lake data indicate nitrogen limitation in June (N/P

    ratio-= 10/1) but phosphorus limitation in September (N/P =

    15/1) and November (N/P = 20/1).

-------
IV.   NUTRIENT LOADINGS
     (See Appendix D for data)
     For the determination  of nutrient loadings,  the  Michigan  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 April  and May, when  two  samples were collected,  and
 in  January when ice cover  prevented sampling  at  most sites.   Sampling
 was begun in October,  1972, and was completed in September, 1973.
     Through an interagency agreement, stream  flow  estimates for the
 year of sampling and a  "normalized" or average year  were provided by
 the Michigan 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  loadings  for
 "minor tributaries and  immediate  drainage" ("II" of  U.S.G.S.) were
                                                 2
 estimated by using the  nutrient loads, in  Ibs/mi /year, in Dumont Creek
                                                   2
 at  station B-l  and multiplying by the II  area in mi  .
     The operators of the Allegan, Kalamazoo,  Otsego, Parchment, and Plain-
 well  wastewater treatment  plants  provided  monthly  effluent samples and
 corresponding flow data.  In this report,  all  of the nutrients  from the
 Allegan STP were assumed to have  reached  Allegan Lake during  the  sampling

sedimentation and/or biological assimilation could have occurred,
only 50% of the phosphorus loads and 80% of the nitrogen loads from
Kalamazoo, Otsego, Parchment, and Plainwell were assumed to have
reached the lake.
    In the following loading tables, the loads attributed to the Kalamazoo
River are those measured at station A-2 minus the STP loads.

                Reportedly, pulp and paper mill wastes, pharmaceutical
            wastes, and meat-packing wastes are discharged to the Kala-
            mazoo River upstream of Lake Allegan.  Whether these wastes
            are untreated, treated separately, or treated jointly with
            domestic wastes is not known, but it appears these wastes
            have a considerable impact on the lake (pages 2 and 3).

    E.  Yearly Loading Rates:

            In the following table, the existing phosphorus loading

        rates are compared to those proposed by Vollenweider (in press).

        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 oligo-

        trophic 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 very short hydraulic retention times.

                                   Total Phosphorus       Total Nitrogen

        grams/m2/yr               31.40      7.38        403.4
        Vollenweider loading rates for phosphorus
         (g/m^/yr) based on mean depth and mean
         hydraulic retention time of Lake Allegan:

            "Dangerous"  (eutrophic rate)       2.50
            "Permissible"  (oligotrophic rate)  1.25
* The apparent loss of nitrogen may be due to nitrogen fixation in the lake,
  solubilization of previously sedimented nitrogen, nitrogen-rich ground
  water recharge, or possibly unsampled point sources between the inlet samp-
  ling station (A-2) and the outlet (A-l).  However, a similar nitrogen loss
  has been observed at Shagawa Lake, Minnesota, which has been studied inten-
  sively by EPA's National  Eutrophication and Lake Restoration Branch.
