                          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)J, 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.

-------
                                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.

ACKNOWLEDGEMENT

I.   CONCLUSIONS
    A.   Trophic Condition:
            Survey data indicate that Lake Tawakoni  is  eutrophic;
        i.e.,  well supplied with nutrients and  quite productive.
        Whether nutrient enrichment  is beneficial  or deleterious
        depends on the actual  or potential effect  on the  uses  of the
        lake.   In this regard,  no nuisance conditions are known to
        personnel of the Texas  Water Quality Board and  there  is little
        or no  impairment of the designated beneficial uses  of  this
        water  body.
            Lake Tawakoni  ranked twenty-eighth  when  the 39  Texas reser-
        voirs  sampled in 1974  were compared using  a  combination of  six
        parameters* as an index to overall trophic quality.  Twenty-six
        of the reservoirs had  less median total  phosphorus, 25 had  less
        and three had the same  median dissolved phosphorus, 11 had  less
        and one had the same median  inorganic nitrogen, 30  had less mean
        chlorophyll  £, and  24  had greater mean  Secchi disc  transparency.
        Marked depression of dissolved oxygen with depth  occurred at
        station 1 in August.
            Survey limnologists observed  surface concentrations of  algae
        at station 6 in March and noted the occurrence  of emergent
  See  Appendix  A.

-------
    macrophytes in the shoreline shallows near stations  3  and
    6 at that time.  Blue-green algae were dominant in the
    August phytoplankton sample (page 9).
        Water milfoil is reported to be very abundant in some
    places in the lake (Moczygemba, 1974), and aquatic macro-
    phytes are a potential problem in the Cowleech Fork embay-
    ment (Anonymous, 1974±?1).
B.  Rate-Limiting Nutrient:
        A significant loss of phosphorus occurred in the assay
    samples between the time of collection (11/01/74) and  the
    beginning of the algal assays, and the results are not
    representative of conditions in the lake at the time the
    samples were taken.  The lake data indicate nitrogen limi-
    tation at all stations in March and November but phosphorus
    limitation at all stations, except station 5, in May.
C.  Nutrient Controllability:
        1.  Point sources—The phosphorus contribution of  the
    point sources considered in this report apparently amounted
    to 23.9% of the total phosphorus load reaching the lake during
    the sampling year.  The City of Greenville contributed 20.9%,
    and five other dischargers collectively contributed  3.0% of
    the total load.
        The present phosphorus loading of 0.91 g/m 2/yr is  three
    times that proposed by Vollenweider (Vollenweider and  Dillon,
    1974) as a eutrophic loading (see page 16).  While even complete

-------
removal of phosphorus at the listed point sources probably
would still leave a loading in excess of the eutrophic loading,
it is likely that a high degree of phosphorus removal  at the
Greenville wastewater treatment plant would result in  improve-
ment in the quality of the Cowleech Fork embayment, particularly
in view of the probable error in the "non-point" load  of the
Cowleech Fork (see below).
    2.  Non-point sources—It is calculated that over  76% of
the total phosphorus load reaching the lake during the sampling
year was contributed by non-point sources, but it is probable
that the actual non-point load was less than indicated.
    The Cowleech Fork apparently contributed 45% of the total
phosphorus load (page 14) and had an exceptionally high export
rate of 175 kg P/km2 (page 16).  However, the high nutrient
concentrations measured at station C-l (Appendix E) probably
resulted from the relatively large amounts of Greenville effluent
in the stream at that point in proportion to the total stream
flow.
    During the sampling year, the mean Greenville discharge was
0.103 m3/sec, and the mean stream flow at the times the samples
were taken was 0.482 m3/sec (highest [30.299 m3/sec] and lowest
[0.003 m3/sec] flows omitted; see Appendix C).  On a yearly mean
basis, then, the Greenville effluent would account for over 21%
of the flow in the stream and, during dry periods, would account

-------
for essentially all of the flow in the stream.   In this  regard,
personnel of the Texas Water Quality Board calculated that 71%
of the Cowleech Fork flow in January, 1974, was Greensville
effluent (Anonymous, 1974[?]).
    Therefore, the true non-point phosphorus load of the Cowleech
Fork must have been much less than was measured; and, conversely,
the proportion of the total load contributed by point sources
must have been more that indicated above.   For example,  if the
actual phosphorus export rate of the Cowleech Fork was the same
as the somewhat high South Fork rate (48 kg/km2/yr), the non-
point contribution of the Cowleech Fork would have been  16,780  kg,
a difference of 44,335 kg; and the proportion of point-source
contribution would be increased from 23.9% to 35.6% of the total
load.

III.   WATER QUALITY SUMMARY
      Lake Tawakoni was sampled four times in 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 six stations on  the
  lake (see map, page vi).   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 November
  visit, two 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 13.7 meters  at station 1, 10.7 meters at station 2, 7.6
  meters at station 3, 9.1  meters at station 4, 4.6 meters at station 5,
  and 3.4 meters at station 6.
      The sampling results  are presented in full in Appendix D  and are
  summarized in the following table (the August nutrient samples  were not
  preserved properly and were not analyzed).

Limiting Nutrient Study:

    A 50% loss of phosphorus occurred in the assay samples  during

shipment from the field to the laborotary, and the algal  assay

results are not representative of conditions in the lake  at  the

time the samples were taken (11/01/74).

-------
                            11
    The lake data indicate a temporal  and spatial  combination

of limiting nutrients.   Following is a tabulation  of the mean

inorganic nitrogen/orthophosphorus ratios for each of the sam-

pling stations and times with the Indicated limiting nutrient

in parentheses.

IV.   NUTRIENT LOADINGS
     (See Appendix E for data)
     For the determination of nutrient loadings,  the Texas National
 Guard collected monthly near-surface grab samples  from each of the
 tributary sites indicated on the map (page vi),  except for the month
 of  June when two samples were  collected.   Sampling was begun in Sep-
 tember, 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 Texas District Office of the U.S. Geological Survey for the
 tributary sites nearest the lake, except  for  the South Fork of the
 Sabine River (station D-l).  The drainage area of  this stream and
 the flow (mean of 15 years) were obtained from U.S.G.S. records
 (Anonymous, 1975).
     Except for the South Fork, nutrient loads in sampled tributaries
 were determined by using a modification of a  U.S.  Geological Survey
 computer for calculating stream loadings*. The  nutrient loads in the
 South Fork were calculated using mean concentrations  and the mean flow.
 Also, the nutrient loads in the water diverted by  the Sabine River
 Authority were calculated using the mean  nutrient  concentrations at
 lake sampling station 1 and the mean diversion flow (Gray, 1976).
 Nutrient loads shown are those measured minus point-source loads, if
 any.
     Nutrient loads for unsampled "minor tributaries and immediate
 drainage" ("ZZ" of U.S.G.S.) were estimated using  the adjusted nutrient
 * See Working Paper No.  175.

                                    13
loads at station B-l, in kg/km2/year, and multiplying by the  ZZ  area
in km2.
    The operators of the Caddo Mills, Celeste,  Greenville,  Quinlan,
Royse City, and Wind Point Park wastewater treatment plants provided
monthly effluent samples and corresponding flow data.
    Four additional municipal  wastewater treatment plants,  with  a
combined effluent flow of 268 m3/day, discharged in the drainage
during the sampling year; however, these plants do not significantly
influence the quality of the receiving streams  and probably have
little effect on the lake (Anonymous, 1974[?]).

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.
