BFN-25 Table 1 (Sheet 2 of 2)
FACTS ABOUT TVA DAMS AND RESERVOIRS a) All in the Tennessee Valley, except for Great Falls which is in the Cumberland Valley.
b) Cost of plant including the inception balance of the plant and all additions and retirements from the plant. Transmission assets are not included.
c) Winter net dependable capacity as of October 2009. Winter net dependable capacity is the amount of power a plant can produce on an average winter day, minus the electricity used by the plant itself.
d) E: Earth; R: Rock fill; G: Gravity; C: Concrete; O: Other (Codes for each dam are listed in order of importance.)
e) At June 1 flood guide elevation.
f) Volume between the January 1 elevation and top of gates.
g) Connected to Barkley Reservoir by 1-1/2 mile canal, which opened July 14, 1966.
h) Acquired: Wilson by transfer from the U.S. Army Corps of Engineers in 1933; Ocoee 1, Ocoee 2, Blue Ridge, and Great Falls by purchase from Tennessee Electric Power Company in 1939; Wilbur and Nolichucky (retired) by purchase from East Tennessee Power and Light Company in 1945.
Subsequent to acquisition, TVA installed additional units at Wilson and Wilbur. Reconstructed flume at Ocoee 2 was placed in service in November 1983.
i) Main locks placed in operation in 1959 at Wilson, 1963 at Wheeler, 1965 at Guntersville, and 1984 at Pickwick Landing.
j) Construction of main lock at Nickajack limited to underwater construction.
k) Generating units at Raccoon Mountain are reversible Francis type pump-turbine units, each with 428,400 kW generator rating and 612,000 hp pump motor rating.
l) Unit 2 at Hiwassee is a reversible Francis type pump-turbine unit with 95,000 kW generator rating and 121,530 hp pump motor rating at 200 ft. net head.
m) Ocoee 1 creates Parksville Reservoir, Nolichucky (retired) creates Davy Crockett Reservoir, and Blue Ridge creates Toccoa Reservoir.
n) Construction of Blue Ridge discontinued early in 1926; resumed in March 1929.
o) Tellico project has no lock or powerhouse. Streamflow through navigable canal to Fort Loudoun Reservoir permits navigation and increases average annual energy output at Fort Loudoun.
p) Initial construction of South Holston and Watauga started February 16, 1942; temporarily discontinued to conserve critical materials during WWII.
q) Generating units at Nolichucky were removed from system generating capacity in August 1972. The dam was renovated and modified to convert the reservoir for use as a wildlife preserve.
r) Includes 72.4 miles up the Tennessee River to Fort Loudoun Dam and 23.1 miles up Clinch River to Melton Hill Dam.
s) Includes 6.5 miles up the French Broad River and 4.4 miles up the Holston River.
t) Includes 17.4 miles up the South Fork Holston River and 15.3 miles up the Watauga River.
u) Includes 73 miles up the Clinch River and 56 miles up the Powell River.
v) The U.S. Army Corps of Engineers is increasing the size of lock structures at Kentucky and Chickamauga.
w) The structural height of the dam is the vertical distance from the lowest point of the excavated foundation to the top of the dam. Top of dam refers to the highest point of the water barrier on an embankment (or top of parapet wall) and deck elevation (or top of parapet wall) for concrete structures.
x) As an interim measure to prevent overtopping, these four dams were raised by HESCO Concertainer floodline units.
Watts Bar - 3 feet: embankment at elevation 767 raised to elevation 770.
Fort Loudoun - 3.75 feet: embankment at elevation 830 was raised 7 feet to elevation 837 (3.75 feet above top of concrete wall at elevation 833.25).
Tellico - 4 feet: embankment at elevation 830 raised to elevation 834.
Cherokee - 3 feet: embankment at elevation 1089 raised to elevation 1092.
