Location
Watts Bar Dam is located approximately 530 miles (850 km) upstream from the mouth of the Tennessee River, roughly halfway between Knoxville and Chattanooga. Just north of the dam, the Tennessee absorbs the Piney River, which flows down from the Cumberland Plateau to the west. The nearest towns of note are Spring City (a few miles to the northwest) and Decatur (a few miles to the south). Tennessee State Route 68 crosses Watts Bar Dam, connecting the area with Interstate 75 to the east and U.S. Route 27 to the west.
