Douglas Dam
Résumé
Douglas Dam is a hydroelectric dam on the French Broad River in Sevier County, Tennessee, in the southeastern United States. The dam is operated by the Tennessee Valley Authority (TVA), which built the dam in record time in the early 1940s to meet emergency energy demands at the height of World War II. Douglas Dam is a straight reinforced concrete gravity-type dam 1705 feet (520 m) long and 202 feet (62 m) high, impounding the Douglas Lake. The dam was named for Douglas Bluff, a cliff overlooking the dam site prior to construction.
The French Broad River winds its way westward from the Appalachian Mountains, gaining considerable strength after absorbing the Pigeon River and Nolichucky River near Newport before eventually joining with the Holston River at Knoxville to form the Tennessee River. Douglas Dam is located above the mouth of the French Broad. The area is a geological border between the Foothills of the Great Smoky Mountains (which rise to the south) and the Appalachian Ridge-and-Valley range. The reservoir includes parts of Sevier, Jefferson, Hamblen, and Cocke counties.
Road access is available by Tennessee State Hwy 338 which crosses just downstream of the dam. Interstate 40 (Exit 407) passes a few miles to the north.
The dam does not have any navigational locks.
During 1941, President Franklin D. Roosevelt requested Congress to allocate funding for a dam on the French Broad River in East Tennessee. After the Japanese attack on Pearl Harbor resulted in the United States entering World War II, construction of this dam became a high priority in order to generate hydroelectric power for national defense purposes. Large amounts of electricity were needed to produce aluminum and magnesium – vital metals for wartime warplane-manufacturing.
When the TVA first asked Congress for the funds to construct Douglas Dam in late 1941, U.S. Senator Kenneth McKellar (D-Tennessee) opposed the project because it would flood some of fertile farmland important to the local food canning industry.
