                         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)]5 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.

-------
    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:
            Portage Lake was sampled only two times.  On the basis of
        these somewhat limited data, it appears that the lake is meso-
        trophic.  Using comparable sampling times, of the 35 Michigan
        lakes on which sampling was completed, only four had less mean
        total and dissolved phosphorus, only two had less mean inorganic
        nitrogen, five had less mean chlorophyll a_, and six had greater
        Secchi disc transparency*.
            Survey limnologists described the overall appearance of the
        lake as "good".
    B.  Rate-Limiting Nutrient:
            The algal assay sample was lost in shipment; however, the
        lake date indicate phosphorus limitation in June and September.
    C.  Nutrient Controllability:
            1.  Point sources—During the sampling year, Portage Lake
        received a total phosphorus load at a rate just in excess of
        the rate proposed by Vollenweider (in press) as "dangerous";
        i.e., a eutrophic rate (see page 12).  Now, Vollenweider's
        model may not apply to water bodies with short hydraulic re-
        tention times, and the hydraulic retention time of Portage Lake
* See Appendix A.

-------
         is not  known.   However, the maximum depth of the lake is 59
         feet; and,  if  it  is assumed that the mean depth is about one-
         third of the maximum depth (20 feet), the mean hydraulic re-
         tention time would be 93 days.  If the assumed mean depth is
         reasonable, it is likely that Vollenweider's model is applicable.
         It is calculated  that the communities of Houghton-Hancock and
         Lake Linden contributed 27% of the total phosphorus load to
         Portage Lake during the sampling year.  Removal of 80% of the
         phosphorus  at  these two point sources would reduce the loading
                        2
         rate to 0.75 g/m  /yr, a mesotrophic loading rate, and would
         protect the existing good water quality of Portage Lake as well
         as provide  additional protection for downstream Lake Superior.
            Reportedly  (Courchaine, 1972), Lake Linden wastewater treat-
        ment facilities were scheduled for construction.
            2.  Non-point sources (see page 12)--The phosphorus exports
         of the sampled  tributaries to Portage Lake were somewhat high
         as compared to  the export of unimpacted Gold Mine Creek tribu-
                                            2
         tary to nearby  Deer Lake* (33 Ibs/mi /yr).
            There are  no  known point sources impacting these streams,
         and it appears  that either the geological characteristics of
         the drainage,  agricultural practices, or both are the cause of
         the relatively  high export rates.
* Working Paper No. 192.

-------
    In all, it is estimated that non-point sources,  including
precipitation, contributed nearly 73% of the total phosphorus
load to Portage Lake during the sampling year.

III.   LAKE WATER QUALITY SUMMARY
      Portage Lake was sampled two 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 two or more 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 identi-
  fication and  enumeration;  and during the second visit, a single five-gallon
  depth-integrated sample was composited  for algal assays (this sample was
  lost in shipment).  Also each time, depth-integrated samples were collected
  from each of  the stations  for chlorophyll a_ analysis.  The maximum depths
  sampled were  43 feet at station 1,  20 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  September sampling period, when the lake essentially was
  well-mixed, are summarized below.   Note, however, the Secchi disc sum-
  mary is based on all values.
      For differences in the various  parameters in June, refer to Appendix
  C.

    Limiting Nutrient Study:

        As noted before, the algal  assay sample was lost in shipment.

    However, the lake data indicate phosphorus limitation in June

    and September (N/P ratios were  15/1 and 21/1, respectively).

                                  8
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.   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 calcu-
 lated using mean concentrations and mean flows.  The nutrient loads for
 the two outlets (A-l and D-l)  were calculated using  the mean  of the
 nutrient concentrations in both and the combined mean  flow ("D-l", Ap-
 pendix B).
     Nutrient loadings for unsampled "minor tributaries and immediate
 drainage" ("ZZ" of U.S.G.S.) were estimated by using the mean concen-
 trations in Boston Creek at station B-l and the  mean ZZ flow.
     The operator of the Houghton-Hancock wastewater  treatment plant
 provided monthly effluent samples and corresponding  flow data.   However,
 during the  sampling year, Lake Linden had no waste treatment  plant, and
 nutrient loads for that source were estimated at 3.5 Ibs P and  9.4 Ibs
 N/capita/year.

-------
    In this report, it is assumed that all  of the nutrients from both

sources reached Portage Lake during the sampling year.

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 oligotrophic
    if morphometry permitted.  A mesotrophic rate would be consid-
    ered one between "dangerous" and "permissible".
        Note that Vollenweider's model  may not be applicable to
    water bodies with very short hydraulic retention times.
