Christopher Smith, 17, of Ventana Drive, Evans, a Greenbrier High student, was swimming with three friends, said Columbia County deputy coroner Bonnie Holloway.
He just kind of went out above his head, and he panicked, she said.
Emergency services received a call about 3:10 p.m. of a possible drowning, according to dive team spokeswoman Honey Shore. A diver with the Columbia County Emergency Management Agencys Dive Rescue Recovery Team found the body about 4:15 p.m., Ms. Shore said.
