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.

HICKORY LAKE
STORET NO. 3705
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.
