On 08/29/10, Operator was operating Vessel #1 in the vicinity of the barrier tires on the south side of Callville Bay.  He had been operating his vessel approximately four hours when he decided to turn sharply to the left.  He was accelerating at the time and his personal watercraft struck a wave which made him turn more sharply than he intended.  He was thrown overboard, but his left foot and ankle became stuck in the footwell of the PWC.  This caused severe pain in his left ankle.  He was unable to climb back aboard his vessel.  He signaled to his friends for assistance and members of his party assisted him to shore where they stabilized him and contacted the National Park Service for assistance.  An NPS volunteer vessel assisted Operator to the launch ramp at Callville Bay Marina, where he was met by NPS Rangers who treated him and transported him to the hospital.  At the hospital they determined Operator had dislocated and broken his ankle.  They set his ankle and several days later he underwent surgery to install two screws and a plate in his ankle to aid in healing.  Operator stated the accident was due to his negligence and not paying attention to the water and his actions.
