FOREWORD
The National Eutrophicatlon 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, concen-
trations, 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 nonpoint source pollution abatement in lake water-
sheds.
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
watershed 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
Elanninq [§303(e)], 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.
-------
iii
Beyond the single lake analysis, broader based correlations
between nutrient concentrations (and loading) and trophic condition
are being made to advance the rationale and data base for refine-
ment of nutrient water quality criteria for the Nation's freshwater
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 the U.S. Environmental
Protection Agency and to augment plans implementation by the
states.

REPORT ON GREAT FALLS LAKE, TENNESSEE
STORET NO. 4713
I. CONCLUSIONS
A. Trophic Condition:*
Based on field observations and Survey data, Great Falls
Reservoir is considered mesotrophic. The lake water was gen-
erally turbid and brown as a result of clay siltation. Median
Secchi disc readings were 50 cm in the spring, and 180 cm in
the summer and fall. Chlorophyll ^values ranged from <0.5 yg/1
in the spring to 8.8 yg/1 in the summer, with a mean of 4.0 yg/l.
Of the 16 Tennessee lakes sampled in 1973, 13 had higher total
phosphorus, 11 had higher inorganic nitrogen, and 14 had higher
orthophosphorus levels than Great Falls Lake.
Survey limnologists reported some emergent and submerged
vegetation in the lake shallows during the fall sampling, but no
visible algal blooms.
B. Rate-Limiting Nutrient:
Algal assay results indicate that Great Falls Reservoir was
limited by available phosphorus. Spikes with phosphorus or phos-
phorus and nitrogen simultaneously resulted in increased assay
yields. The addition of nitrogen alone did not stimulate a growth
*See Appendix E.
-------
response. The lake ratios (N/P) of total available inorganic ni-
trogen to orthophosphorus (32/1 or greater on all sampling occa-
sions) substantiate these results.
C. Nutrient Controllability:
1. Point sources -
During the sampling year, known point sources accounted
for 14.3% of the total phosphorus load reaching Great Falls
Lake. The city of McMinnville was estimated to have contri-
buted 9.3%, and the city of Sparta to have contributed 3.6%.
Septic tank seepage from the Levi Strauss & Co. plant into
the Rocky River is known to exist (S. Fishel, pers. comm.);
however, nutrient contributions from that unmeasured seepage
are not quantified at this time.
The calculated phosphorus loading of 15.37 g P/m2/yr is
approximately five times that proposed by Vollenweider (1975)
as "eutrophic" for a lake of such volume and retention times.
The combination of a mesotrophic condition and high phosphorus
loading is possible because Vollenweider's model probably is
not applicable to lakes with short hydraulic retention time
(8 days for Great Falls Lake), or in which epilimnetic light
penetration is severely reduced by the presence of suspended
sediments in the surface waters. In any case, it does not
appear likely that point-source phosphorus control would re-
sult in any appreciable improvement in the trophic condition
of the lake.
-------
2. Nonpoint sources -
The total phosphorus load from nonpoint sources ac-
counted for 85.7% of the loading reaching the impoundment.
The Collins River contributed 62.2%, and the Calfkiller
River contributed 12.3% of the total. Ungaged tributaries
were estimated to have contributed 1.4%.
The Collins River and Calfkiller River had phosphorus
2 2
export rates of 45 kg/km /yr and 33 kg/km /yr, respectively.
These rates are much higher than the rates of other unim-
pacted tributaries to Great Falls Reservoir (see Section IV-D).
Such inflation of background nutrient loading may be due to
underestimation of the known municipal point source contribu-
tions to the two rivers, or to unknown point sources existing
upstream. Further study is recommended to determine the cause
of these high export rates.
-------
II. LAKE AND DRAINAGE BASIN CHARACTERISTICS
Lake and drainage basin characteristics are itemized below.
Lake morphometry data and hydraulic retention time were provided
by the Tennessee Valley Authority. Tributary flow data were pro-
vided by the Tennessee District Office of the U.S. Geological
Survey (USGS). Outlet drainage area includes the lake surface
area. Drainage area for tributary B(l), the Collins River, was
provided by the Tennessee Valley Authority. Tributary drainage
areas plus the lake surface area do not equal the outlet drain-
age area, probably because of differences in the pool elevation
used by the different sources in their calculations. Precipita-
tion values are estimated by methods as outlined in National
Eutrophication Survey (NES) Working Paper No. 175. A table of
metric/English conversions is included as Appendix A.

III. LAKE WATER QUALITY SUMMARY
Great Falls 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 four stations on the lake
and one or more depths at each station (see map, page v).
During each visit, depth-integrated samples were collected
from each station for chlorophyll a^ analysis and phytoplankton
identification and enumeration. During the first visit,
18.9-liter depth-integrated samples were composited for
algal assays. Maximum depths sampled were 19.8 meters at
Station 1, 16.8 meters at Station 2, 11.9 meters at Station 3,
and 7.9 meters at Station 4. For a more detailed explanation
of National Eutrophication Survey methods, see NES Working
Paper No. 175.
The results obtained are presented in full in Appendix C
and are summarized in III-A for waters at the surface and
at the maximum depth for each site. Results of the phyto-
plankton counts and chlorophyll ^determinations are included
in III-B. Results of the limiting nutrient study are presented
in III-C.

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum. suggests that primary productivity was low in
Great Falls Reservoir at the time of sampling. The lake was
phosphorus limited at that time as indicated by the increased
growth of the test alga in response to the addition of ortho-
phosphorus. Spikes with nitrogen and phosphorus simultaneous-
ly resulted in maximum yield, while the addition of nitrogen
alone did not stimulate growth beyond the control yield. The
lake's total N/P ratios for spring, summer, and fall were res-
pectively 53/1, 67/1, and 32/1, further indicating phosphorus
limitation.

VI. NUTRIENT LOADINGS
(See Appendix D for data)
For the determination of nutrient loadings, the Tennessee
National Guard collected monthly near-surface grab samples from
each of the tributary sites indicated on the map (page v), ex-
cept for the high runoff month of February when two samples were
collected. Sampling was begun in April 1973, and was completed
in March 1974 for sites A(1)-C(1). Sampling was completed in
April 1974 for sites D(1)-G(1).
Through an interagency agreement, stream flow estimates
for the year of sampling and a "normalized" or average year
were provided by the Tennessee District Office of the USGS for
the tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were
determined by using a modification of a USGS computer program for
calculating stream loadings. Nutrient loads indicated for tribu-
taries are those measured minus known point source loads, if any.
Nutrient loadings for unsampled "minor tributaries and imme-
diate drainage" ("II" of USGS) were estimated by using the mean
annual nutrient loads, in kg/km2/yr, for Cane Creek and Caney Fork
at Stations D(l) and E(l), and by multiplying the means by the II
area in km^.
Nutrient loads for the cities of Sparta, McMinnville, and
Morrison wastewater treatment plants were estimated at 1.134 kg P
and 3.401 kg N/capita/yr.

E. Yearly Loading:
In the following table, the existing phosphorus annual
loading is compared to the relationship proposed by Vollenweider
(1975). Essentially, his "eutrophic" loading is that at which the
receiving waters would become eutrophic or remain eutrophic; his
"oligotrophic" loading is that which would result in the receiving
water remaining oligotrophic or becoming oligotrophic if morphome-
try permitted. A "mesotrophic" loading would be considered one
between eutrophic and oligotrophic.
Note that Vollenweider's model may not apply to lakes with
short hydraulic retention times or in which light penetration is
severely restricted by high concentrations of suspended solids in
the surface waters.
