Hoover Dam Hoover Dam, originally known as Boulder Dam from 1933 to 1947, when it was officially renamed Hoover Dam by a joint resolution of Congress, is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. The dam was named after President Herbert Hoover.
Fort Loudoun Dam 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 652 mi 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 14600 acre 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.
