                         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)]s 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 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.

    A. Gene Gazlay, former Director, and David H. Jenkins, Acting
Director, Michigan Department of Natural Resources; and Carlos
Fetterolf, Chief Environmental Scientist, and Dennis Tierney,
Aquatic Biologist, Bureau of Water Management, Department of Natural
Resources, provided invaluable lake documentation and counsel during
the course of the Survey.  John Vogt, Chief of the Bureau of Environ-
mental Health, Michigan Department of Public Health, and his staff
were most helpful in identfying point sources and soliciting municipal
participation in the Survey.

    Major General Clarence A. Schnipke (Retired), then the Adjutant
General of Michigan, and Project Officer Colonel Albert W. Lesky,
who directed the volunteer efforts of the Michigan National Guardsmen,
are also gratefully acknowledged for their assistance to the Survey.

I.  CONCLUSIONS
    A.  Trophic Condition:
            On the basis of Survey data, it is concluded that Higgins
        Lake is oligotrophic.  Of the 35 Michigan lakes sampled in
        November when essentially all were well-mixed, only one had
        less mean dissolved and total phosphorus, and none had less
        mean inorganic nitrogen*.  Of all of the 41 Michigan lakes
        sampled, none had greater mean Secchi disc transparency, and
        none had less mean chlorophyll a_.
    B.  Rate-Limiting Nutrient:
            A significant loss of nutrients occurred in the algal assay
        sample, and the results are not indicative of conditions in the
        lake at the time the sample was collected.
            The lake data indicate phosphorus limitation in September
        but narrow nitrogen limitation in June and November of 1972.
    C.  Nutrient Controllability:
            1.  Point sources—During the sampling year, it is calculated
        that Higgins Lake received a total phosphorus load at a rate about
        one-third of that proposed by Vollenweider (in press) as "permis-
        sible"; i.e., at a rate less than an oligotrophic rate (see page
        10).
* See Appendix A.

-------
    There are no known municipal or industrial point sources
impacting Higgins Lake; and, although septic tanks were estimated
to have contributed 28% of the total phosphorus load, a shoreline
survey would be needed to determine the actual contribution from
these sources.
    While the present phosphorus loading rate is quite low,
every effort should be made to reduce all phosphorus inputs to
the lowest practicable level to ensure that the existing high
quality of Higgins Lake is maintained.
    2.  Non-point sources (see page 10)--It is estimated that
non-point sources, including precipitation, contributed nearly
72% of the total phosphorus load to Higgins Lake during the
sampling year.  However, the phosphorus export of the only
stream sampled, Big Creek, was the lowest of any of the Michi-
gan streams sampled in 1972.

III.   LAKE WATER QUALITY SUMMARY
      Higgins Lake 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 from a number of depths at each station (see
  map, page v).  During each visit, a single depth-integrated (15 feet to
  surface) sample was composited from the three 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, a depth-integrated sample was collected from each of the  sta-
  tions for chlorophyll a_ analyses.  The maximum depths sampled were 100  feet
  at station 1, 35 feet at station 2, and 89 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.
      For differences in the various parameters at the other sampling  times,

C.  Limiting Nutrient Study:

        There was a loss of about 56% of dissolved phosphorus and

    inorganic nitrogen in the algal assay sample from the time of

    collection until the assay was begun.  Consequently, the algal

    assay results are not indicative of conditions in the lake at

    the time the sample was collected.

        The lake data indicate phosphorus limitation in September

    (N/P ratio = 16/1) but narrow nitrogen limitation the other

    sampling times (N/P ratios = 12/1).  Phosphorus limitation

    would be expected at about 14/1 and higher.

-------
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
 the colder months when  flows were too low in Big Creek.  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 unsamp-
 led "minor tributaries  and immediate drainage"  ("II" of U.S.G.S.) were
 estimated by using the  means of  the nutrient loads,  in Ibs/mi2/year,  in
 Big Creek at station  B-l and multiplying the means by the ZZ  area in  mi2.
     There are no known  municipal or industrial  point sources  impacting
 Higgins Lake.

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 waters 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".
