A teenager from Southern California apparently drowned at Lake Mohave early Saturday afternoon, according to the National Park Service. Lake Mead National Recreation area spokeswoman Christie Vanover said the incident at Cabinsite Cove was reported at about 12:22 p.m.

“Witnesses said the teen swam out to help another person in his party who became separated from a tube they were floating on,” Vanover said in a news release. “The victim, who was not wearing a life jacket, went under water.”

Bullhead City Fire Department spokeswoman Lori Viles said divers from the department later recovered the body from about 45 feet below the lake surface. The victim’s name was initially withheld and the cause of death will be determined by the Mohave County Medical examiner.
