The Little Tennessee River (known locally as the Little T) is a 135-mile (217 km) tributary of the Tennessee River that flows through the Blue Ridge Mountains in the southeastern United States from Georgia, into North Carolina, and then into Tennessee. Reaching its confluence with the Tennesssee River at Lenoir City, Tennessee, it drains portions of three national forests— Chattahoochee, Nantahala, and Cherokee— and provides the southwestern boundary of the Great Smoky Mountains National Park.
Numerous dams were erected on the river in the 20th century for flood control and hydropower generation. The river flows through five major impoundments: Fontana Dam, Cheoah Dam, Calderwood Dam, Chilhowee Dam, and Tellico Dam, and one smaller impoundment, Porters Bend Dam.
