Man made lake in Georgia and South Carolina, United States

Lake Strom Thurmond, officially designated J. Strom Thurmond Reservoir at the federal level, and Clarks Hill Lake by the state of Georgia, Its legally authorized purposes now include recreation, water quality, water supply, and fish and wildlife management. Each year, millions of people use the many public parks, marinas, and campgrounds conveniently located around Thurmond Lake for a variety of outdoor recreational experiences, making it one of the 10 most visited Corps lakes in the nation. Thurmond Lake is a man made lake bordering Georgia and South Carolina on the Savannah, Broad, and Little Rivers. The lake is created by the J. Strom Thurmond Dam located on the Savannah River 22 mile (35 km) above Augusta, Georgia and 239.5 mile (385 km) above the mouth of the Savannah River. The lake extends 39.4 mile (63 km) up the Savannah River, 29 mile (47 km) up the Little River in Georgia, and 6.5 mile (10 km) up the Broad River in Georgia, and 17 mile (27 km) up the Little River in South Carolina, at normal pool elevation of 330 mean sea level, Thurmond Lake comprises nearly 71,100 acres (287 km2) of water with a shoreline of 1200 mile (1931 km). The entire Thurmond "project" contains 151,000 acres (611 km2) of land and water. J. Strom Thurmond Lake and Dam is the first Corps of Engineers project to be built in the Savannah River Basin. Hartwell Lake and Dam the second project built in the basin was completed in 1963, and a third project, Richard B. Russell Lake and Dam was completed in 1985. Together these three lakes form a chain of lakes that is 120 mile (193 km) long. Congress authorized Thurmond Lake in 1944 and construction began in 1946. The project was completed in 1954 at a cost of $79 million.

Due to a clerical error in the original Congressional Authorization, the project was officially authorized to build "Clark Hill Dam", creating "Clark Hill Lake", with the "s" at the end of "Clarks" accidentally omitted. The authorization document outlined the plan of development for the basin with authorized purposes of power production, incidental flood control, and navigation. Later, recreation, water quality, water supply, and fish and wildlife management were added as authorized purposes. Twenty six years after the construction of the dam, both the dam and lake were renamed to "Clarks Hill Dam" and "Clarks Hill Lake", respectively, in legislation sponsored by Strom Thurmond. The 1966 Flood Control Act authorized the building of Trotters Shoals Lake and Dam on the Savannah River between Clarks Hill Lake and Hartwell Lake. This lake was later renamed to commemorate a late senator from Georgia, Richard B. Russell, who was an important supporter of building dams on the river. This created a movement to rename Clarks Hill Lake after J. Strom Thurmond, the longest serving senator in US history, who was from Edgefield on the South Carolina side of the lake. This movement gained support due to the senator's popularity in the area, and in 1988 the project was congressionally renamed "J. Strom Thurmond Dam and Lake at Clarks Hill."

Until 1987, the lake was called Clarks Hill Lake after the nearby South Carolina town of Clarks Hill named for Augusta businessman John Mulford Clark (1813–1880). (See "Years Gone By: Information on the Origin of the Names Clarks Hill," Reservoirs—Clarks II Subjects, DOC 1991, Georgia Archives, Morrow.) On December 3, 1987, two days before long time South Carolina Senator Strom Thurmond's 85th birthday, Representative Butler Derrick of South Carolina introduced a bill before Congress to rename the lake after Thurmond. Many residents of both states were upset by the sudden change of name of the lake and the dam, which had not been open to public comment. In response, a group of Georgia legislators, led by Representative Doug Barnard, Jr. (who was the only Georgia co sponsor of the original 1987 bill) introduced a federal bill to rename the lake as "Clarks Hill" once again. That bill, however, was unsuccessful, and the name remained unchanged. On April 4, 1989, the State of Georgia legislature passed House Resolution No. 115 making "Clarks Hill" the official state name for both the dam and associated reservoir. Accordingly, Georgia's state map still refers to the lake as Clarks Hill. Many residents of Georgia as well as South Carolina still refer to the lake by its original name.
