1940-1948: Construction In the aftermath of the December 7, 1941
attack on Pearl Harbor, the U.S. Congress authorized the use of War Department funds to build dams at Center Hill and
Dale Hollow that would generate the power required to support defense industry in the
Southeastern United States. In early 1942, the Corps opened bidding to private contractors. An $11,666,000 contract was awarded to a joint venture firm made up of the
Massman Construction Company,
Metcalf Construction Company and
Gordon Hamilton Contracting Company. Wartime manpower and material shortages began to slow work on the dam beginning in fall of 1942. In 1943, the Corps suspended construction on Center Hill to focus on the completion of the dam at Dale Hollow. After
World War II ended, construction resumed in January 1946. Modifications to the
Rivers and Harbors Act authorized Center Hill Dam for power production. Construction of the dam's basic flood control mechanisms was completed in November 1948 and Center Hill Lake was created as the reservoir was filled.
1949-1951: Completion of Power Production Facilities To avoid a loss of momentum, the existing contract with Massman-Metcalf-Gordon was modified to include the construction of power producing facilities. Construction ended in spring of 1951 and totaled around $100 million.
2008-2020: Repairs and Reopening Center Hill Dam required three phases of repair work that cost an estimated $353 million. Work began in 2008 and reached completion in 2020. Between 2005 and 2020, the lake's water levels were reduced by as much as 18 feet. During the first phase of repairs, concrete was pumped into the foundation to fill gaps that formed as the structure decayed. In the second phase, a 308-foot tall foundation wall was installed on the dam's lake side to stop leaks through the limestone. The third phase saw the construction of an additional auxiliary dam on Center Hill Dam's eastern side to be used to reduce pressure on the main dam during a major flood. Improvements were made by the
Army Corps of Engineers to recreational areas around the lake and the parking lot was greatly expanded. Electricity from the dam is marketed by the
Southeastern Power Administration. ==References==
