                         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)j, clean lakes [§314(a,b)L
and water quality monitoring [§106 and §305(b)] activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.
* The lake discussed in this report was included in the National
  Eutrophication Survey as a water body of interest to the Michigan
  Department of Natural Resources.  Tributaries and nutrient sources
  were not sampled, and this report relates only to the data obtained
  from lake sampling.

-------
                                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.

                        CONSTANTINE RESERVOIR
                           STORE! NO.  2621

 I.   INTRODUCTION
     Constant!ne Reservoir was  included in  the National  Eutrophication
 Survey as a water body of interest to the  Michigan Department of
 Natural  Resources.   Tributaries  and nutrient sources  were  not sampled,
 and this report relates only to  the data obtained from  lake  sampling.
II.   CONCLUSIONS
     A.   Trophic Condition:
             Survey  data show that Constant!'ne Reservoir is eutrophic.
         Of the 35 Michigan lakes sampled in the fall  when  essentially
         all  were well-mixed, nine had less mean total phosphorus,  four
         had less mean  dissolved  phosphorus,  and 20 had  less  mean inor-
         ganic  nitrogen; of all 41  lakes  sampled,  39 had less mean  chloro-
         phyll  a_, and 27 had a  greater mean Secchi disc  transparency*.
             Survey  limnologists  noted rooted aquatic  vegetation  along
         the north shore and observed  algal  blooms in  June  and September.
     B.   Rate-Limiting  Nutrient:
             The algal  assay results indicate that Constant!'ne Reservoir
         was phosphorus limited at the time the sample was  collected
         (09/17/72).  The reservoir data  indicate  phosphorus  limitation
         in November but a marginal  nitrogen  limitation  in  June.

IV.   LAKE WATER QUALITY SUMMARY
     Lake Constant!ne 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 two stations on the reservoir and from a number of 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, a depth-integrated sample was collected
 from each of the stations for chlorophyll  a_ analysis.  The maximum
 depths sampled were 10 feet at station 1  and 10 feet at station 2.
                                                       *
     The results obtained are presented in  full in Appendix B, and the
 data for the fall sampling period, when  the reservoir 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, refer to Appendix B.

    2.  Discussion -
            The control  yield of the assay alga, Selenastrum  capri-
        cornutum, indicates that the potential  primary productivity
        of Constantine Reservoir was quite high at the time the
        assay sample was collected (09/17/72).  Also,  the increased
        yields with increased levels of orthophosphorus indicate
        phosphorus limitation (note the lack of yield  response when
        only nitrogen was added).
            The lake data indicate phosphorus limitation in November
        as well (N/P ratio = 114/1) but a  marginal nitrogen limitation
        in June (N/P = 13/1).
