                          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 freshwater 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)L 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
freshwater 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 North Dakota State Depart-
ment of Health for professional involvement, to the North Dakota
National Guard for conducting the tributary sampling phase of the
Survey, and to those North Dakota wastewater treatment plant oper-
ators who voluntarily provided effluent samples and flow data.

    Norman L. Peterson, Director, and the staff of the Division
of Water Supply and Pollution Control of the Department of Health,
provided invaluable lake documentation and counsel during the
Survey, reviewed the preliminary reports, and provided critiques
most useful in the preparation of this Working Paper series.

I.  CONCLUSIONS
    A.  Trophic Condition:
            Survey data indicate that Whitman Lake is eutrophic.  It
        ranked eleventh in overall trophic quality when the 14 North
        Dakota lakes sampled in 1974 were compared using a combination
        of six parameters*.  Nine of the lakes had less and one had the
        same median total  phosphorus, 11  had less median dissolved ortho-
        phosphorus, nine had less median inorganic nitrogen, seven had
        less mean chlorophyll a^ and all  of the other lakes had greater
        mean Seechi disc transparency.  Depletion of hypolimnetic dis-
        solved oxygen was not observed but has been reported to occur
        (Peterson, 1975).
            Survey limnologists noted the presence of emergent aquatic
        vegetation near both sampling stations on all three sampling
        occasions (however, the vegetation observed in April was dead).
        Heavy algal blooms were observed in the lake in July and Sep-
        tember.
    B.  Rate-Limiting Nutrient:
            The algal assay results indicate that the lake was nitrogen
        limited in April and September when the assay samples were col-
        lected.  The lake data indicate nitrogen limitation all three
        sampling times.

                                 2
C.  Nutrient Controllability:
        1.   Point sources—No  significant point sources  are  known
    to impact Whitman Lake.
        2.   Non-point sources—Non-point sources accounted for  an
    estimated 99% of the total  phosphorus load received  by the  lake
    during the sampling year.   Most of this (about 89%)  was  con-
    tributed by the Middle Branch of the Forest River.
        The estimated phosphorus loading of 0.83 g/mz/yr is  over
    two times that proposed by Vollenweider (Vollenweider and Dillon,
    1974) as a eutrophic loading (see page 11).  A large reduction
    in this loading probably would be necessary to improve the tro-
    phic condition of the lake noticeably.  However, since much of
    the phosphorus load results from agricultural practices  (Peter-
    son, 1974), this may be difficult to achieve.

III.   LAKE WATER QUALITY SUMMARY
      Whitman Lake was sampled three times during the open-water season
  of 1974 by means of a pontoon-equipped Huey helicopter.   Each time,
  samples for physical and chemical  parameters were collected from two
  or more depths at two stations on  the lake (see map, page v).  During
  each visit, a single depth-Integrated (4.6 m or near bottom to surface)
  sample was composited from the stations for phytoplankton identification
  and enumeration; and during the first and last visits, single 18.9-
  liter depth-integrated samples were 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
  4.9 meters at station 1 and 2.4 meters at station 2.
      The sampling results are presented in full in Appendix D and are
  summarized in the following table.

    2.   Discussion -

            The control  yields of the assay alga,  Selenastrum capri-

        cornutum.  indicate that the potential  primary productivity

        of Whitman Lake was high at the times  the  assay samples

        were collected (04/29/74 and 09/16/74).  Also,  significant

        increases  in yield with the addition of  nitrogen alone indi-

        cate that  the lake was limited by nitrogen at those times.

        Note that  the addition of phosphorus alone resulted in yields

        not significantly greater than those of  the controls.

            The lake data also indicate nitrogen limitation;  i.e.,

        the mean inorganic nitrogen to orthophosphorus  ratios  were

        9 to 1  or  less each sampling time.

IV.   NUTRIENT LOADINGS
     (See Appendix E for data)
     For the determination of nutrient loadings,  when possible the
 North Dakota 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 month of May when two samples were collected.
 Sampling was begun in September, 1974, and was completed in August, 1975.
     Through an interagency agreement, stream flow estimates for the
 year of sampling and a "normalized" or average year were provided by
 the North Dakota District Office of the U.S. Geological  Survey for the
 tributary sites nearest the lake.
     In this report, nutrient loads for sampled tributaries were
 calculated using mean annual concentrations and mean annual flows.
 Nutrient loads for unsampled "minor tributaries and immediate
 drainage" ("ZZ" of U.S.G.S.) were estimated using the mean concen-
 trations in the Middle Branch Forest River at station A-2 and the
 mean annual ZZ flow.

    E.   Yearly Loads:
            In the following table,  the existing phosphorus loadings
        are compared to those proposed  by Vollenweider (Vollenweider
        and Dillon, 1974).   Essentially, his "dangerous" loading is
        one at which the receiving water would become eutrophic or
        remain eutrophic; his "permissible" loading is that which
        would result in the receiving water remaining oligotrophic
        or becoming oligotrophic if morphometry permitted.   A meso-
        trophic loading would be considered one between "dangerous"
        and "permissible".
            Note that Vollenweider's model may not be applicable to
        water bodies with short hydraulic retention times.
                                  Total Phosphorus       Total Nitrogen

        grams/m2/yr             0.83       loss*       9.2         none
        Vollenweider phosphorus loadings
         (g/m2/yr) based on mean depth and mean
         hydraulic retention time of Whitman Lake:
            "Dangerous"  (eutrophic loading)              0.38
            "Permissible"  (oligotrophic loading)         0.19
* There was an apparent loss of phosphorus during the sampling year.   This
  may have been due to sol utilization of previously sedimented phosphorus,
  unknown and unsampled point sources discharging directly to the lake,  or
  underestimation of the minor tributary and immediate drainage load.
