1. The TVA System of Multipurpose Dams Marker
The Tennessee River has its headwaters in the mountains of Tennessee, Virginia, North Carolina and Georgia. The main stream forms at Knoxville, where the Houston and the French Broad Rivers join.

The valley, 41,000 square miles in area, receives an average of 52 inches of rain a year. In terms of water discharged into the Ohio and Mississippi, the Tennessee River is about equal in size to the Missouri.

The Tennessee Valley Authority has harnessed the river with a multi-purpose system of dams and reservoirs which regulates floods, improves navigation, and generates electric power.

High dams on the tributaries create large storage reservoirs which hold back flood waters, releasing them when necessary to maintain navigation depths downstream, and at the same time generating electric power. The system also helps protect the lower Ohio and Mississippi Valleys.

The nine main river dams, with their locks, form a navigable channel 650 miles long, from Knoxville to the Ohio River, an important arm of the nation's inland waterway system connecting 20 states.

Having developed virtually all the river power resources, TVA has built huge coal-burning steam electric plants to help serve the region's growing power needs. TVA power is sold at wholesale to cities and rural electric cooperatives which, in turn, distribute

it at retail to homes, farms, business and industry. A few industries and U.S. Government Defense installations that use large amounts of power are served directly by TVA. The largest of these, using more power than a great city, are the atomic plants at Oak Ridge, Tennessee, and Paducah, Kentucky.


You are now at Nickajack Dam, a multipurpose dam on the main stream of the Tennessee River. It generates electricity and forms a 46-mile link in the Tennessee Waterway. Nickajack was built 1964-1968 to replace Hales Bar Dam 6 miles upstream. Completed in 1913, Hales Bar was built on leaking limestone foundations and had to be demolished.
