Context: Ocoee Dam Number 2 is a hydroelectric dam on the Ocoee River in Polk County in the U.S. state of Tennessee. The dam impounds the Ocoee No. 2 Reservoir and is one of four dams on the Toccoa/Ocoee River owned and operated by the Tennessee Valley Authority. Ocoee Dam No. 2 which was completed in 1913 is perhaps most notable for its design which utilizes a wooden flume that carries water from the reservoir down the side of the Ocoee Gorge to the dam's powerhouse 5 miles (8.0 km) downstream.
