A one-of-a-kind warm-water drift dive on 18,000-acre Lake Keowee, where the Oconee Nuclear Station's cooling discharge blows warmed water (up to ~80 F) back into the lake near Duke Energy's World of Energy site off Rochester Highway. Upstate divers and the Clemson Scuba Club ride the outflow current like a roller coaster, descending a rope to about 30 ft before letting go; the warm plume meets 50s F lake water at the edges. Visibility is poor and the current strength varies with the plant's cycle.
