                          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)], 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.

    Major General LaClair A. Melhouse, the Adjutant General of
North Dakota, and Project Officer Colonel Irvin M. Sande, who
directed the volunteer efforts of the North Dakota National
Guardsmen, are also gratefully acknowledged for their assistance
to the Survey.

I.  CONCLUSIONS
    A.  Trophic Condition:
            Lake Sakakawea ranked third in overall trophic quality
        when the 14 North Dakota lakes sampled in 1974 were compared
        using a combination of six parameters*.  However, the lake
        data show that this long water body (ca. 286 km; see map, page
        v) is oligotrophic from the dam to the vicinity of the Little
        Missouri embayment; mesotrophic in the vicinity of sampling
        station 5 and, on the basis of limited nutrient data, in the
        Little Missouri embayment (station 10); eutrophic at stations
        6 and 7; and hypereutrophic at station 8.  Essentially, station
        9 was a river station; Survey limnologists noted a defined
        channel, perceptable current, and sediment turbidity.
            At oligotrophic stations 1, 2, 3, and 49 spring and fall
        mean total phosphorus ranged from 10 to 21 yg/1; spring and fall
        mean orthophosphorus ranged from 3 to 9 yg/1; mean chlorophyll a_
        ranged from 1.3 to 2.3 yg/1; and mean Secchi disc transparency
        ranged from 2.5 to 4.3 meters.  No significant depression of dis-
        solved oxygen occurred at any of the four stations at depths as
        great as 53.6 meters.
            At mesotrophic stations 5 and 10, spring and fall mean total
        phosphorus ranged from 16 to 32 yg/1; spring and fall mean ortho-
        phosphorus ranged from 4 to 18 yg/1; mean chlorophyll a_ ranged

                                 2
    from 2.0 to 3.0 yg/1; and mean Secchi disc transparency ranged
    from 1.5 to 4.0 meters.  Depression of dissolved oxygen with
    depth occurred at station 5 in September (to 4.8 mg/1 at 33.5
    meters); the maximum depth sampled at station 10 was 2^4 meters.
        At eutrophic stations 6 and 7, spring and fall mean total
    phosphorus ranged from 21 to 53 yg/1; spring and fall mean
    orthophosphorus ranged from 6 to 19 yg/1; mean chlorophyll a^
    ranged from 7.2 to 7.6 yg/1; and mean Secchi disc transparency
    ranged from 0.8 to 1.4 meters.  Some depression of dissolved
    oxygen with depth occurred at both stations in July (the maxi-
                                        t
    mum depth sampled was 22.9 meters).
        At hypereutrophic station 8, the means of the spring and
    fall total  phosphorus were 158 and 61 yg/1; the means of the
    spring and fall orthophosphorus were 15 and 12 yg/1; the mean
    chlorophyll a^was 30.3 yg/1; and the mean Secchi disc trans-
    parency was 0.3 meters.
B.  Rate-Limiting Nutrient:
        The algal assay results indicate Lake Sakakawea was phos-
    phorus limited at the time the three samples were collected
    (04/30/74).  However, the lake data indicate that station 8
    was nitrogen limited at that time.
        The July lake data indicate phosphorus limitation at sta-
    tions 1, 2, 3, and 4 but nitrogen limitation at station 5.
    The September data indicate phosphorus limitation at stations

        1, 2, 3, 4, and 10 and nitrogen limitation at stations 5
        through 9.
    C.  Nutrient Controllability:
            1.  Point sources—The phosphorus contribution of point
        sources considered in this report accounted for less than
        1% of the total load reaching the lake during the sampling
        year.  However, there are many municipal  and industrial
        point sources beyond the 40-kilometer limit of the Survey*—
        including the Montana communities of Glendive, Miles City,
        and Billings and a number of industries  on the Yellowstone
        River and Glasgow, Havre, and Great Falls and industries
        in the Missouri River drainage—so the actual point-source
        phosphorus load is not known.
            The present phosphorus loading of 4.49 g/m2/yr is over
        six times that proposed by Vollenweider  (Vollenweider and
        Dillon, 1974) as a eutrophic loading (see page 17).   It  is
        calculated that an 85% reduction (ca. 5,700,000 kg)  of the
        entire phosphorus load measured during the sampling  year
        would be required to just equal a eutrophic loading, and it
        is questionable whether even complete removal of point-source
        phosphorus would reduce the load that much.  However, unless
        the present loading can be reduced, an increasingly  greater
        proportion of Lake Sakakawea will become  eutrophic,  and  every
        effort should be made to reduce all phosphorus inputs to the
        greatest practicable degree to at least  slow the rate of eutro-

phication of the lake.
    2.  Non-point sources—It is calculated that the gaged
tributaries contributed nearly 95% of the total  phosphorus
load during the sampling year.  The Yellowstone  River load
amounted to 70.0% of the total, the Missouri River load
accounted for 25.4%, and the remaining five gaged tributaries
collectively contributed 1.4% of the load.
    Except for the Yellowstone River and Moccasin Creek,
the phosphorus export rates of the gaged tributaries were
quite low (see page 16).  The high rate of the Yellowstone
River probably was the result of the unsampled point sources
noted above.  However, the cause of the relatively high
Moccasin Creek rate is not evident in Survey data and avail-
able information.
    While nutrient concentrations in the smaller gaged streams
were quite high (Appendix E), the low, sometimes intermittent
flows of these streams (Appendix C) resulted in  low nutrient
loads.  The nutrient concentrations in sampled but ungaged
tributaries also were quite high (see page 16),  but it is
likely that these streams have low flows (and loads) as well.

III.   LAKE WATER QUALITY SUMMARY
      Lake Sakakawea was sampled three times during the open-water
  season of 1974 by means of a pontoon-equipped Huey helicopter.  Samples
  for physical  and chemical parameters were collected from ten  stations
  on  the lake (nine in April) and from a number of depths  at each station
  (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  April  visit,
  three 18.9-liter depth-integrated samples were composited for
  algal assays  (stations 1, 2, and 3 were combined; 4,  5,  and 6 were  com-
  bined; and 7, 8, and 9 were combined).  Also each time,  a depth-integrated
  sample was collected from each of the stations for chlorophyll a_  analysis.
  The maximum depths sampled were 53.6 meters at station 1, 19.8 meters at
  station 2, 38.4 meters at station 3, 24.7 meters at station 4, 33.5
  meters at station 5, 22.9 meters at station 6, 9.4 meters at  station 7,
  2.7 meters at station 8, near-surface only at station 9, and  2.4  meters
  at  station 10.
      The sampling results are presented in full in Appendix D  and
  are summarized in the following table.

Discussion -
    The control yield of the assay alga, Selenastrum capri-
cornutum, indicates that the potential primary productivity
of Lake Sakakawea was low in the mid and lower portions
and moderately low in the upper portion at the time the
samples were collected (04/30/74).  Also, the increased
yields when orthophosphorus was added, and the lack of
yield responses when only nitrogen was added, indicate the
lake was phosphorus limited at that time.
    The lake data indicate a temporal and spatial combin-
ation of limiting nutrients, although it will be noted that
the stations nearest the major tributaries and point sources
tended toward nitrogen limitation while the stations further
away tended toward phosphorus limitation.
    Following is a tabulation of the mean inorganic nitrogen/
orthophosphorus ratios for each of the stations and sampling
times with the indicated limiting nutrient in parentheses
(the July nutrient samples from stations 6 through 10 were

IV.   NUTRIENT LOADINGS
     (See Appendix E for data)
     For the determination of nutrient loadings,  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 high runoff months when two samples were collected  from most
 of the sites.  Sampling was begun in September,  1974, and  was com-
 pleted 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
 selected 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 com-
 puter program for calculating stream loadings*.   Nutrient  loads shown
 are those measured minus known point-source loads,  if any.
     Nutrient loads for unsampled "minor tributaries and immediate
 drainage" ("ZZ" of U.S.G.S.) were estimated using the means of the
 nutrient loads, in kg/km2/year, at stations C-l,  G-l, R-l,  and S-l
 and multiplying the means by the ZZ  area in km2.
     The operator of the Williston wastewater treatment  plant provided
 ten effluent samples but insufficient flow data;  the operator of the
 Garrison plant submitted only two effluent samples; and the communities
 of New Town and Parshall did not participate.  Nutrient loads for all
 * See Working Paper No. 175.

four sources were estimated at 1.134 kg P and 3.401 kg N/capita/year.
    The results of the analyses of the Mil listen and Garrison effluent
samples are included in Appendix E for the record.

F.   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.
