                               FOREWORD
     The National Eutrophicatlon 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,  concen-
trations, 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 nonpoint source pollution abatement in lake water-
sheds.

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
watershed 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 condition
are being made to advance the rationale and data base for refine-
ment 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 the U.S. Environmental
Protection Agency and to augment plans implementation by the
states.

                REPORT ON REELFOOT LAKE,  TENNESSEE
                          STORET NO.  4727

I.    CONCLUSIONS
     A.    Trophic Condition:*
               On the basis of Survey data and field  observations,
          Reelfoot Lake is considered hypereutrophic.   The  lake is
          characterized by extremely  high nutrient levels and  phyto-
          plankton concentrations, low Secchi  disc transparency
          (mean 60.3 cm) and high potential  for primary production
          as measured by algal  assay  control yield.   Chlorophyll  a_
          values ranged from a low of 16.2 yg/1 in the spring  to  a
          high of 161.9 yg/1 in the summer.  Of the 16 lakes  sampled
          in Tennessee, none had greater  median total  phosphorus,
          14 had greater median inorganic nitrogen,  and 1 had  greater
          median dissolved phosphorus than Reelfoot Lake.
               Survey limnologists reported visible algal blooms  and
          floating duckweed, water hyacinths,  and water lilies.  The
          Tennessee Soil Conservation Service  has a program proposed
          for alleviating the sedimentation problem in Reelfoot Lake
          by damming up several tributaries to the lake (Martin,  per-
          sonal communication).

     *See Appendix E.

-------
B.   Rate-Limiting Nutrient:
          Algal assay results indicate that Reelfoot Lake was lim-
     ited by available nitrogen levels.  The ratios of available
     nitrogen to orthophosphorus (N/P) in sampled waters (5/1 or less
     on all sampling occasions) further indicate nitrogen limitation.
C.   Nutrient Controllability:
     1.   Point sources -
               There are no known municipal or industrial point sources
          contributing to Reelfoot Lake.  Septic tanks were estimated
          to have contributed only 0.1% of the total load to the lake,
          while the Reelfoot Creek Packaging Company Feedlot contri-
          buted 52.5% of the total phosphorus load.
     2.   Nonpoint sources -
               Major tributaries contributed 21.8% of the total phos-
          phorus load to Reelfoot Lake, while minor tributaries were
          estimated to have contributed 9.0% of the load.
               Reelfoot Lake is a combined National Wildlife Refuge
          Area and a State Wildlife Management Area.  Considerable
          numbers of resident and migratory ducks and geese utilize
          the reservoir.  On the basis of the numbers provided by the
          Tennessee Wildlife Resources Authority and certain assump-
          tions (see page 12), it is estimated that wild ducks and
          geese contributed 18,715 kg of total phosphorus (16.1% of the
          total load) to the reservoir during the sampling year.

-------
     According to the U.S.  Geological  Survey (USGS)
there is no continuous discharge from the lake,  only
seepage, and it is assumed  that the lake is a sink.
The Jackson Office of the Department of Public Health
has indicated that there is an intermittent flow which
is lake-level dependent from Reelfoot Lake into  Running
Reelfoot Bayou (W. Max, personal communication).  Never-
theless, this periodic outlet was not gaged in this  Sur-
vey and no statements can be made as to its effect on the
nutrient budget of the lake.

III.  LAKE WATER QUALITY SUMMARY
          Reel foot Lake was sampled three times  during the
     open-water season of 1973 by means of a pontoon-equipped
     Huey helicopter.   Each time, samples for physical and chemical
     parameters were collected from four stations on the lake and
     from one or more depths at each station (see map, page  ).
     During each visit, depth-integrated samples were collected
     from each station for chlorophyll  a_ analysis and phytoplankton
     identification and enumeration.  During the first visit, an
     18.9-liter depth-integrated sample was composited for algal
     assays.   Maximum depths sampled were 3.0 meters at Station  1,
     2.7 meters at Station 2, 0.9 meters at Station 3, and 1.5 meters
     at Station 4.  For a more detailed explanation of NES methods,
     see NES Working Paper No. 175.
          The results obtained are presented in  full in Appendix C
     and are summarized in III-A for waters at the surface and at
     the maximum depth for each site.   Results of the phytoplankton
     counts and chlorophyll ^determinations are included in III-B.
     Results of the limiting nutrient study are  presented in III-C.

     3.   Discussion -
               The control  yield of the assay alga, Selenastrum
          capricornutum, indicates that the potential  for primary
          production was high in Reel foot Lake at the  time of sam-
          pling.  The response to the addition of nitrogen to the
          autoclaved sample, as well as the lack of response to the
          addition of phosphorus, indicates nitrogen limitation.
          Maximum yield was achieved with the simultaneous addition
          of both phosphorus and nitrogen.
               The mean N/P ratios for the spring, summer, and fall
          lake sampling were respectively 5/1, 2/1, and 3/1, all
          indicating nitrogen limitation.

IV.   NUTRIENT LOADINGS
     (See Appendix D for data)
          For the determination of nutrient loadings,  the Tennessee
     National Guard collected monthly near-surface  grab  samples  from
     each of the tributary sites indicated on  the map  (page  i),  ex-
     cept for the high runoff months of February and March when  two
     samples were collected.  Sampling was begun in April 1973,  and
     was completed in March 1974.
          Through an interagency agreement, stream  flow  estimates for
     the year of sampling and a "normalized" or average  year were pro-
     vided by the Tennessee District Office of the  USGS  for  the  tribu-
     tary sites nearest the lake.
          In this report, nutrient loads for sampled tributaries, ex-
     cept for Reel foot Creek, B(l), were determined by using a modi-
     fication of a USGS computer program for calculating stream  load-
     ings.  Nutrient loads indicated for tributaries are those mea-
     sured minus known point source loads, if  any.
          Nutrient loadings for unsampled "minor tributaries and imme-
     diate drainage" ("ZZ" of USGS) and Reelfoot Creek,  B(l), were
     estimated by using the mean annual  nutrient loads,  in kg/km2/yr,
     for Running Slough and Indian Creek at Stations A(l) and C(l),
                                                                   2
     respectively, and by multiplying the means by  the ZZ area in km  .
          Estimates on nutrient contributions  by Reelfoot Creek  Packing
     Company Feedlot were calculated at 17.60  kg P  and 57.49 kg  N/animal/
     yr (Omernik 1976).

-------
                               11
     Estimates of nutrient contributions by wild ducks and
geese were based on the following number of waterfowl  using
Reel foot Lake as provided by the Tennessee Wildlife Resources
Authority (Fox 1976):
          Summer resident mallard ducks      1,000
          Year round wood ducks              3,500
          Winter resident mallard ducks    175,000
          Migratory Canada geese            25,000
     In calculating the nutrient loads the following assump-
tions were made:
     1.   Each wild duck contributes 0.45 kg total nitrogen and
     0.20 kg phosphorus per year (Paloumpis and Starrett 1960).
     2.   Each wild goose contributes the same amount as one
     duck since geese typically feed in fields away from the
     lake several hours each day.
     3.   Summer resident waterfowl are at the lake for six
     months of the year.
     4.   Migratory waterfowl spend a total of one month per
     year at the lake, i.e., 15 days during spring migration
     and 15 days during fall migration.
