Authorised by the United States Congress in the Rivers and Harbors Act of 1946 as the Jim WoodruffLock and Dam Project, construction began the following year. With the dam completed in 1952, in 1957 the lake was opened. The project was expected to cost $29 million USD, but when completed had required $46.5 million USD. The lake is named after the Seminole Indians. In 2000, in a case that later made national news, a Tallahassee man, Michael Williams, was believed to have drowned while duck hunting on the Jackson County, Fla., side of the lake. However, his body could not be found during a 44-day search, which was unprecedented for a drowning victim in the large but relatively shallow lake. Some searchers speculated that the body had been eaten by alligators, though naturalists said the animals would not have been feeding in December, when Williams disappeared. Other oddities with the incident convinced officials to suspect foul play. After Williams was declared dead, his widow, Denise Williams, married a man named Brian Winchester. Years later, their marriage fell apart, and Winchester was eventually convicted of kidnapping her and holding her at gunpoint. During the legal proceedings against him, Winchester admitted to authorities that he had killed Michael Williams and staged the disappearance in 2000 as part of a conspiracy with Denise Williams, his lover at the time. He then led police to the man's buried remains. Denise Williams was convicted of murder in December 2018.
The Jim Woodruff Dam, located about south of the original confluence of the Chattahoochee River, Flint River and Spring Creek to form the Apalachicola River and with a spillway wide, is a hydroelectric and navigational dam named in honor of James W. Woodruff, Sr., a Georgia businessman who spearheaded the development of the Apalachicola-Chattahoochee-Flint Project. The dam crosses the state line between Georgia and Florida, with the eastern end of the dam being located in Georgia and the majority, including the locks, gates, spillway, and the powerhouse all being within Florida, just 100 feet south of the southeast corner of Georgia.
Navigation
The Jim Woodruff Dam has a single lock, in length and wide, that provides navigational access to the lake and the upstream rivers from the Apalachicola River and Gulf of Mexico. Lake Seminole extends upstream along the Chattahoochee River for and up the Flint River for.
was built in 1816 on the west bank of the Flint River, just before it empties into the Apalachicola. The intent was to protect what was then the southern border of the United States, subject to various types of invaders operating through or out of Spanish territory. The Fort was abandoned after Florida became a U.S. territory in 1821 and there was no longer a border to defend. The site is under Lake Seminole.
