                         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)]s 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.

 I.  CONCLUSIONS
    A.  Trophic Condition:
            Survey data indicate that Lake Hickory is eutrophic.  However,
        since the mean hydraulic retention time of the lake is a rather
        short 33 days, it more closely resembles a slow-moving river; and
        the term "over-enriched" may be a more appropriate description of
        the condition of the lake.
            Lake Hickory ranked tenth in overall trophic quality when the
        16 North Carolina lakes sampled in 1973 were compared using a
        combination of six parameters*.  Eleven of the lakes had less
        median total  phosphorus, seven had less and two had the same
        median dissolved phosphorus, six had less median inorganic nitrogen,
        13 had less mean chlorophyll a^, and seven had greater mean Secchi
        disc transparency.  Depression of dissolved oxygen with depth
        occurred at all  four sampling stations in July and September.
            Survey limnologists noted that the water was turbid on all
        sampling occasions.   No algal blooms were observed, although
        phytoplankton numbers in September indicate a near-bloom condition,
        and blue-green genera were dominant.
* See Appendix A.

-------
    B.  Rate-Limiting Nutrient:
            The algal assay results show that Lake Hickory was  phos-
        phorus limited at the time the sample was collected.  The  lake
        data also indicate phosphorus limitation at all  stations and
        sampling times (the mean N/P ratios were 18/1  or greater,  and
        phosphorus limitation would be expected).
    C.  Nutrient Controllability:
            1.  Point sources—During the sampling year, it is  estimated
        that the phosphorus contribution of known point  sources amounted
        to 11.0% of the total load reaching the lake.
            The calculated phosphorus loading rate of  6.08 g/m2/yr is
        three times that proposed by Vollenweider (Vollenweider and
        Dillon, 1974) as a eutrophic rate (see page 14).  However, because
        of the relatively short hydraulic retention time of Lake Hickory,
        Vollenweider's model may not be applicable. Nonetheless,  the
        existing trophic condition of the lake is evidence of excessive
        nutrient loads.
            Because Lake Hickory is phosphorus limited,  point-source
        phosphorus control would be expected to result in an improved
        trophic condition, particularly if the point sources impacting
        upstream Rhodhiss Lake* are also controlled.
* Working Paper No. 388.

-------
            It is likely that point-source phosphorus  control would
        benefit downstream Lookout Shoals Lake* as  well.
            2.  Non-point sources—The Catawba River accounted  for
        about 89% of the total phosphorus load to Lake Hickory  during
        the sampling year and had a phosphorus export  rate  of 29
        kg/km2/yr (see page 14).   The export rate of the  unnamed stream
        at station C-l was a relatively high 44 kg  P/km2/yr and probably
        was due to urban drainage from the City of  Hickory. However,
        the total phosphorus contribution of the stream was only Q.3%
        of the total phosphorus load to the lake.

III.   LAKE WATER  QUALITY  SUMMARY
      Lake Hickory was  sampled  three times during the open-water season
  of 1973 by means of a pontoonTequipped Huey helicopter.  Each time,
  samples for physical  and chemical parameters were collected from
  four stations on the  lake  and from a number of depths at each station
  (see map, page  v).  During each visit, a single depth-integrated
  (4.6 m to surface) sample  was composited from the four stations for
  phytoplankton identification  and enumeration; and during the first
  visit, a single 18.9-liter depth-integrated sample was 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 13.4 meters at station 1, 16.2 meters at station
  2,  12.2 meters  at  station  3,  and 25.9 meters at station 4.
      The lake sampling results are presented in full in Appendix D and
  are summarized  in  the following table.

    2.  Discussion -
            The control yield of the assay alga, Selenastrum  capri-
        cornutum, indicates that the potential  primary  productivity
        of Hickory Lake was high at the time the assay  sample was
        collected (03/30/73).  Also, the N/P ratio of the  control
        sample and the response to the phosphorus  only  spike  show
        that the lake was phosphorus limited at that time.  Note

-------
that the yield resulting from the  nitrogen  only spike was
essentially the same as  the  control yield.
    The lake data indicate phosphorus  limitation at all
stations and sampling times; I.e., the mean N/P ratios were
18/1 or greater, and phosphorus  limitation would be expected.

IV.   NUTRIENT LOADINGS
     (See Appendix E for data)
     For the determination of nutrient  loadings, the North Carolina
 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 January  and March,  1974, when two samples were
 collected.   Sampling was begun in March,  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 provided by
 the North Carolina District Office of  the U.S. Geological Survey for
 the tributary sites nearest the lake.
     In this report, nutrient loads for sampled tributaries were deter-
 mined by using a modification  of a U.S. Geological Survey computer
 program for calculating stream loadings*.  Nutrient loads shown are
 those measured minus point-source loads,  if any.
     The inlet of Lookout Shoals Lake and  the outlet of Lake Hickory
 were sampled in the same place but not at the same time.  For consis-
 tency, the nutrient loads for  the outlet  of Lake Hickory (3705A1) were
 calculated using the concentrations  and flows measured at the inlet of
 Lookout Shoals Lake (3710A2).   These data are included in Appendix E.
     Nutrient loads for unsampled "minor tributaries and immediate
 drainage" ("IT1 of U.S.G.S.) were estimated using the means of the
 * See Working Paper No.  175.

                                 11
nutrient  loads, in kg/km2/year, at stations B-l, E-l, and F-l  and
multiplying the means by the ZZ area in km2.
    The operator of the Granite Falls wastewater treatment plant pro-
vided monthly effluent samples and corresponding flow data.  The
operator  of the Hickory southeast wastewater treatment plant also
provided  monthly samples and corresponding flow data.   However,  it
was learned that this plant discharges to Clark Creek which is not a
tributary of Lake Hickory.  However, the obtained data are included
in Appendix D.
    The operator of the Hickory northeast wastewater treatment plant
did not participate, but the plant does impact Lake Hickory (Kirby,
1974), and nutrient loads from this source were estimated at 1.134 kg
P and 3.401 kg N/capita/year.   The Town of Rhodhiss also did not
participate in the sampling program, and nutrient loads were estimated
using the factors given above.

E.  Yearly Loading Rates:
        In the following table, the existing phosphorus loading
    rates are compared to those proposed by Vollenweider {Vollen-
    weider and Dillon, 1974).   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
    oligotrophlc if morphometry permitted.   A mesotrophic rate 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.

    grams/m2/yr             6.08       1.79       109.4       39.9

    Vollenweider loading rates for phosphorus
     (g/m2/yr) based on mean depth  and mean
     hydraulic retention time  of Lake Hickory:
        "Dangerous"  (eutrophic rate)       1.94
        "Permissible"  (oligotrophic  rate)   0.97
