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)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.
-------
Ill
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 Nottely Reservoir is mesotrophic.
It ranked fourth in overall trophic quality when all 14 Georgia
lakes sampled in 1973 were compared using a combination of six
parameters**. Three of the lakes had less median total phos-
phorus, one had less and two had the same median dissolved
phosphorus, four had less median inorganic nitrogen, five had
less mean chlorophyll a_, and four had greater mean Secchi disc
transparency.
Depression of dissolved oxygen occurred in the thermocline
and hypolimnion at all sampling stations in June, and oxygen
depletion occurred in the hypolimnion at all stations in Sep-
tember.
No algal blooms or aquatic vegetation were observed by/
Survey limnologists, and personnel of the Georgia Department
of Natural Resources know of no problems in the reservoir
(Hall, 1975).
B. Rate-Limiting Nutrient:
The algal assay results indicate that Nottely Reservoir
was limited by phosphorus at the time the assay sample was

-------
collected. These results are substantiated by the reservoir
data; i.e., the mean N/P ratios were 16/1 or greater at all
sampling times.
C. Nutrient Controllability:
1. Point sources—During the sampling year, the estimated
phosphorus contribution from point sources, including septic
tanks, amounted to 4.5% of the total load. The Blairsville
wastewater treatment plant is estimated to have contributed
4.2% of this total.
The present total phosphorus loading rate of 0.75 g/m2/yr
is below the rate proposed by Vollenweider (Vollenweider and
Dillon, 1974) as a eutrophic rate but greater than his proposed
oligotrophic rate; i.e., a mesotrophic rate (see page 14).
Complete removal of point-source phosphorus loads would reduce
the loading rate to 0.72 g/m2/yr but probably would not result
in a significant change in the trophic condition of this
reservoir.
2. Non-point sources—The phosphorus contribution from
non-point sources, including precipitation, amounted to 95.5%
of the total load during the sampling year. Nottely Creek
contributed 44.6%, Youngcane Creek contributed 11.9%, and the
remaining two tributaries contributed 9.0%, collectively. The
ungaged tributaries were estimated to have contributed 27.7%.
-------
The phosphorus export rates of the Nottely Reservoir
tributaries ranged from 12 to 27 kg/km2/yr with a mean of
20 kg/km2/yr (see page 14). These rates compare well with
the export rates of tributaries to nearby Blue Ridge Lake*
(range of 9 to 27 kg/km2/yr; mean of 18 kg/km2/yr) and
Chatuge Lake** (range of 14 to 24 kg/km2/yr; mean of 21
kg/km2/yr).

III. LAKE WATER QUALITY SUMMARY
Nottely Reservoir was sampled three times during the open-water
season of 1972 by means of a pontoon-equipped Huey helicopter. Each
time, samples for physical and chemical parameters were collected from
three 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 three 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 36.6 meters at station 1, 36.0 meters at station 2,
and 22.9 meters at station 3.
The results are summarized in the following table and are
presented in full in Appendix D.

3. Discussion -
The control yields of the assay alga, Selenastrum caprj-
cornutum, indicate that the potential primary productivity
of Nottely Reservoir was low at the time the sample was taken.
Also, increasing yields with increasing concentrations of
orthophosphorus indicate that the lake was phosphorus limited
at that time. Note that the addition of only nitrogen did not
alter the yield as compared to that of the control.
The reservoir data also indicate phosphorus limitation.
On all sampling occasions, the mean ratios of inorganic nitro-
gen to orthophosphorus were 16 to 1 or greater.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Georgia 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 month of February when two samples were collected. Sampling
was begun in March, 1973, and was completed in February, 1974.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Georgia District Office of the U.S. Geological Survey for the
tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were
determined by using a modification of a U.S. Geological Survey com-
puter program for calculating stream loadings*. Nutrient loadings
for unsampled "minor tributaries and immediate drainage" ("ZZ" of
U.S.G.S.) were estimated by using the means of the nutrient loads,
in kg/km2/year, at stations C-l and D-l and multiplying the means by
the ZZ area in km2.
The City of Blairsville did not participate in the Survey, and
nutrient loads were estimated at 1.134 kg P and 3.401 kg N/capita/year.
Also, the Vogel State Park wastewater treatment facility, which dis-
charges to the East Fork of Wolf Creek, was not sampled. However, in
* See Working Paper No. 175.

a recent Georgia Department of Natural Resources report (Anonymous, 1973),
the stream was classified as "healthy" at a sampling station less than two
miles downstream from the park, so it is not likely that this point source
contributes significant amounts of nutrients to Nottely Reservoir.
The only industrial waste source in the drainage, the Joseph Campbell
Company, only discharges brine (Anonymous, 1972) and is not believed to be
of nutrient significance.

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.
