Construction History
From the ENR Archives: April 4, 1940
This 1940 cover photo shows a streamlined crane lowering the first rotor into position at the Hiwassee Dam in North Carolina. The concrete gravity-overflow dam was built by the Tennessee Valley Authority to control flooding on the Hiwassee River, which had contributed to regular seasonal flooding in the city of Chattanooga. At 307 ft tall and 1,376 ft long, it is the highest overspill dam east of the Mississippi River.
