                         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.

-------
                                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.

    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.

    CONCLUSIONS
    A.  Trophic Condition:
            Survey data show that Crystal Lake is oligotrophic.   Of the
        35 Michigan lakes sampled in the fall of 1972 when essentially
        all were well-mixed, three had less mean total phosphorus, two
        had less mean total dissolved phosphorus, and three had less
        mean inorganic nitrogen; of all 41 Michigan lakes sampled, only
        two lakes had less mean chlorophyll a^, and three had a greater
        mean Secchi disc transparency*.
    B.  Rate-Limiting Nutrient:
            Phosphorus was determined to be the limiting nutrient 'based
        on the results of the algal assay.  The lake data also indicate
        that phosphorus was the limiting nutrient during all sampling
        periods (N/P ratios were greater than 14/1).
    C.  Nutrient Controllability:
            1.  Point sources—During the sampling year, Crystal Lake
        received a total phosphorus load at a rate less than that pro-
        posed by Vollenweider (in press) as "permissible"; i.e., an
        oligotrophic rate (see page n).  Of that load, septic tanks
        are estimated to have contributed about 16% (there are no other
* See Appendix A.

-------
known point sources).  However, a shoreline survey would be
needed to determine the actual contributions 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 protect the existing high
quality of Crystal Lake.
    2.  Non-point sources—The mean annual contribution from
non-point sources was estimated to be almost 85% of the total
phosphorus load reaching Crystal Lake.
   .The phosphorus export of the unnamed stream (B-l) does not
appear to be excessive (see page 11) and is comparable to the
exports of other Michigan streams sampled.

III.   LAKE WATER QUALITY SUMMARY
      Crystal 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 (two in November) and from a number of depths at
  each station (see map, page v).  During each visit, a single depth-
  integrated (15 feet or 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, a depth-integrated
  sample was collected from each of the stations for chlorophyll a_ analy-
  sis.  The maximum depths sampled were 19 feet at station 1, 37 feet at
  station 2, and 7 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 was essentially well-mixed,
  are summarized below.  Note, h&wever, the Secchi disc summary is based on
  all values.
      For differences in the various parameters at the other sampling times,
  refer to Appendix C.

        cornutum, indicates that the potential primary productivity

        was low at the time the sample was collected.  The increase

        in yield with the addition of phosphorus (to about 0.020

        mg/1) indicates phosphorus limitation.  Note the lack of

        yield response when only nitrogen was added.

IV.   NUTRIENT LOADINGS
     (See Appendix D for data)
     For the determination of nutrient loadings,  the Michigan  National
                                                                  fc
 Guard collected monthly near-surface grab samples from each of the  tribu-
 tary sites indicated on the map (page v), except for the high runoff
 months of January, March, and May when two samples were collected.   Samp-
 ling was begun in October, 1972, and was completed in October, 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 determined
 by using a modification of a U.S. Geological Survey computer  program for
 calculating stream loadings*.  Nutrient loadings for unsampled "minor
 tributaries and immediate drainage" ("II" of U.S.G.S.) were estimated
                                                 2
 using the means of the nutrient loads, in Ibs/mi /year, at station  B-l
                                               2
 and multiplying the means by the II area in mi .

    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 rate1 would be consid-
    ered one between "dangerous" and "permissible".
        Note that Vollenweider's model may not be applicable to
    water bodies with very short retention times.
