Calvert City in Marshall County, Kentucky — The American South (East South Central)
The TVA System of Multi-Purpose Dams
Kentucky Dam
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's 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 Kentucky Dam near the mouth of the Tennessee. It has special importance for flood control. Kentucky Reservoir extending southward 184 wiles, can hold back the waters of the Tennessee when floods threaten on the Lower Ohio and Mississippi. Kentucky Dam also provides for commercial navigation and power generation.
Built for the people of the United States of America.
Erected by Tennessee Valley Authority.
