Fort Loudoun Dam is a hydroelectric dam on the Tennessee River in Loudon County, Tennessee, in the southeastern United States. The dam is operated by the Tennessee Valley Authority (TVA), which built the dam in the early 1940s as part of a unified plan to provide electricity and flood control in the Tennessee Valley and create a continuous 652mi navigable river channel from Knoxville, Tennessee to Paducah, Kentucky. It is the uppermost of nine TVA dams on the Tennessee River. The dam impounds the 14600acre Fort Loudoun Lake and its tailwaters are part of Watts Bar Lake. The generating capacity of Fort Loudoun Dam is enhanced by the Tellico Reservoir, from which water is diverted via canal to Fort Loudoun Lake.Fort Loudoun Dam is named after Fort Loudoun, an 18th-century British colonial fort built during the French and Indian War. The fort— which was located about 10mi south of the dam site— was named for John Campbell, 4th Earl of Loudoun, commander of British forces in North America during this period.LocationFort Loudoun Dam is located at just over 602mi upstream from the mouth of the Tennessee River and nearly 50mi downstream from the river's source at the confluence of the Holston and French Broad at Knoxville. The river's natural confluence with the Little Tennessee River is located approximately 1mi downstream, although the Tellico Reservoir, which covers most of the lower Little Tennessee, is connected to Fort Loudoun Lake via canal which empties into the lake upstream from the dam. Lenoir City is located immediately north of Fort Loudoun Dam. The reservoir includes parts of Loudon, Blount, and Knox counties.
