In 1927 the Jackson Bluff Dam was constructed on the
Ochlockonee River to produce
hydroelectric power. The waters held back by the dam formed Lake Talquin. The dam was constructed by the
Florida Power Corporation which operated the dam's hydroelectric plant through 1970. it is one of only two hydroelectric power plants in the state of Florida. In 1970, approximately 20,000 acres (80 km2) of uplands and 10,000 acres (40 km2) of lake bottom were donated by Florida Power to the State of Florida to form Lake Talquin State Recreation Area, now
Lake Talquin State Park, and Florida Power handed over the dam's ownership to the State of Florida;
Incidents On September 30, 1957, the dam suffered a failure due to the lake being overfilled. On August 18, 1962, the lake was the site of a tragedy when 17 children and one adult drowned in the capsizing of a boat while they were on an outing. In 2008 and 2009, releases of water from the dam to prevent a potential failure caused downstream flooding. == Topography ==
