My late father...always wanted a place to fish, and after I got some seniority in the Senate, I could get enough money for the lake, so I got it and named it in his honor.
— John David Long III, Washington Post
The lake was created in the 1970s on the initiative of South Carolina state senator John David Long III and named for his father, John David Long, also a South Carolina state senator.[6] An earthen dam was built at a pasture on Hughes Creek to fill it.[2]
Nine people have died at the lake's old boat ramp, which had been located near the dam at the eastern end. In 1994, Susan Smith drowned her two sons there, in a case which attracted national attention. Granite memorials were raised to the boys, and many visitors came. In 1996 seven people died when their car rolled down the boat ramp into the lake,[7] after which the memorials were moved and the boat ramp dug up and grassed over.[8]
On July 1, 2013, the lake was closed for two years for renovation and restoration by the South Carolina Department of Natural Resources. The balance between the bream (specifically bluegill and shellcracker) and largemouth bass populations had become upset and the lake had become overcrowded with bass. The state stunned and relocated the bass, drained the lake, cut and planted trees, and laid down 635.7 short tons (576,700 kg) of gravel to create spawning grounds for bluegill and shellcracker. The lake was refilled, and reopened for fishing on July 1, 2015; catfish were introduced later.[3]
