Construction of Watts Bar Dam began in 1939. It was completed in January 1942, three weeks after Pearl Harbor, and provided urgently needed electricity for the war effort—including the Manhattan Project at nearby Oak Ridge National Laboratories.

Watts Bar Reservoir is on the Tennessee River in east Tennessee. It extends 72.4 miles northeast from the dam to Fort Loudoun Dam. The dam has five generating units with a net dependable capacity of 182 megawatts.

Watts Bar Dam, located about midway between Knoxville and Chattanooga, is one of nine TVA dams on the Tennessee River. The reservoir is popular for boating, fishing, swimming, camping and other outdoor activities. A scenic overlook near the dam provides visitors with a panoramic view of the reservoir and surrounding countryside.

Before TVA created Watts Bar and other reservoirs above Chattanooga, the city had one of the most serious flooding problems in the nation. Now the river that often threatened the city contributes to its economy as a major artery for barge traffic—thanks in large part to large reservoirs like Watts Bar and adjacent Chickamauga.
