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)], water
quality criteria/standards review [§303(c)], clean lakes [§314(a,bJ],
and water quality monitoring [§106 and §305(b)] activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.
-------
111
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, multlvarlate 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.

HIWASSEE LAKE
STORE! NO. 3707
I. CONCLUSIONS
A. Trophic Condition:
Survey data show that Hiwassee Lake 1s mesotrophic. Of
the 16 North Carolina lakes and reservoirs sampled in 1973,
it ranked fourth in overall trophic quality based on an index
of six water quality parameters*. Two of the lakes had less
median total phosphorus, five had less and one had the same
median dissolved phosphorus, three had less median inorganic
nitrogen, eight had less mean chlorophyll a_, and only two had
a greater Secchi disc transparency. Depression of dissolved
oxygen with depth occurred at station 1 in August and October
and at station 2 in August.
During their visits to the lake, Survey limnologists did
not observe any nuisance conditions. However, one of the June
phytoplankton samples indicates a near-bloom of blue-green
algae (see page 7}.
B. Rate-Limiting Nutrient:
The algal assay results indicate Hiwassee Lake was phosphorus
limited at the time the samples were collected (06/01-02/73). The
lake data indicate phosphorus limitation at all sampling times;
See Appendix A.
-------
i.e., the mean N/P ratios were 14/1 or greater at all sampling
stations and times, and phosphorus limitation would be expected.
C. Nutrient Controllability:
1. Point sources—Point sources contributed 9.6% of the
total phosphorus load to Hiwassee Lake during the sampling
year. The Murphy wastewater treatment plant contributed 5.2%,
the Andrews plant contributed 3.5%, and the Hayesville plant .
contributed 1.1% of this total.
The present loading rate of 1.8 g/m2/yr is slightly above
the rate proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic rate (see page 15). A high degree of
phosphorus control at the listed point sources should ensure
the existing quality of Hiwassee Lake.
2. Non-point sources—The phosphorus contribution of
non-point sources amounted to 90.2% of the total reaching the
lake. The gaged tributaries contributed a total of 82.6% and
ranged from 36.3% (Hiwassee River) to 1.1% {Bearpaw Creek).
The ungaged tributaries were estimated to have contributed 6.6%
of the total.
The mean of the phosphorus export rates of the Hiwassee Lake
tributaries was a relatively low 18 kg/km2/yr (see page 14). The
somewhat higher rate of Bearpaw Creek (37 kg/km2/yr) may be the
result of an error in the estimate of the size of the drainage
area since no point sources are known to impact the creek.

III. LAKE WATER QUALITY SUMMARY
Hiwassee 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 six
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 stations for phytoplankton
identification and enumeration; and during the first visit, two 18.9-
liter depth-Integrated samples were composited for algal assays (sta-
tions 1, 2, and 3 were combined, and stations 4, 5, and 6 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
67.4 meters at station 1, 54.6 meters at station 2, 29.9 meters at
station 3, 17.7 meters at station 4, 16.5 meters at station 5, and
24.1 meters at station 6.
The lake sampling results are presented in full 1n Appendix D and
are summarized in the following table.

3. Discussion -
The control yields of the assay alga, Selenastrum capri-
cornutum, indicate that the potential primary productivity
of Hiwassee Lake was low at the time the samples were col-
lected. The results also indicate the lake was phosphorus
limited at that time. Significant Increases in yields
occurred when orthophosphorus was added, but there were no
yield responses when only nitrogen was added.
The lake data indicate phosphorus limitation in August
and October as well; I.e., the mean inorganic nitrogen to
orthophosphorus ratios were 14 to 1 or greater at all samp-
ling stations.

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 February when two samples were col-
lected. Sampling was begun in March, 1973, and was completed in Febru-
ary, 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.
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 B-l, C-l, D-l, E-l, and
G-l and multiplying the means by the ZZ area in km2.
The operators of the wastewater treatment plants at Andrews and
Hayesville did not participate, and the operator of the Murphy waste -
water treatment plant provided only one effluent sample and corresponding
flow data. Therefore, the nutrient loads from these sources were esti-
mated at 1.134 kg P and 3.401 kg N/capita/yr.

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
oligotrophic 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.
Total Phosphorus Total Nitrogen
Total Accumulated Total Accumulated
grams/mVyr 1.79 0.80 37.6 loss*
Vollenweider loading rates for phosphorus
(g/m2/yr) based on mean depth and mean
hydraulic retention time of Hiwassee Lake:
"Dangerous" (eutrophic rate) 1.56
"Permissible" (oligotrophic rate) 0.78
* There was an apparent loss of nitrogen during the sampling year. This
may have been due to nitrogen fixation in the lake, solubilization of
previously sedimented nitrogen, recharge with nitrogen-rich ground water,
or unknown and unsampled point sources discharging directly to the lake.
Whatever the cause, a similar nitrogen loss has occurred at Shagawa Lake,
Minnesota, which has been intensively studied by EPA's National Eutro-
phication and Lake Restoration Branch (Malueg et al., 1975).
