Deputies say it appears the man found shortly before 10 p.m. Saturday had drowned.
Coroner Ed Allen said the man was 33-year-old Derek Oliver Griner of Hampton.
Deputies say Griner's body was found shortly before a female acquaintance called to report he failed to return from a swim.
Investigators say there is no sign of foul play.
Allen says an autopsy is planned Monday at the Medical University of South Carolina in Charleston.
