RedactedNarrative: On 6/22/14 at approximately 6:00pm, operator was operating his pwc on upchurche's pond in rockfish creek when he drove under a metal support cable which struck him in the neck and was then thrown off the back of his pwc. After interviewing operator, he told me he was operating his pwc in rockfish creek next to camp rockfish when he went out of his intended direction well before coming up to 2 fishermen in a small vessel in order for his wake not to disturb them. He slowed to approximately 10-12 mph to go around the fishermen. He was close to camp rockfish, a kids camp, where there are structures for rope swings, slides, etc. However, there were no "danger" or "no wake buoys" on the end of the camp where he had his accident. He did not see the metal support cable which went from one of the structures into an anchor point in the water. His pwc went under the cable and the cable struck him in the neck under his chin and threw him backwards off his vessel into the water. He was wearing a type iii pfd and the kill switch lanyard was removed which stopped the motor of the vessel. He was pulled out of the water by the two fishermen he was trying to avoid. 911 was called and responded by taking him to the hospital for treatment. He suffered a neck laceration due to the cable. There was slight damage to the pwc where the cable slid up the front of the vessel, light scratch. The pwc did not strike any other objects or the shore. Upon investigation, a few days after the accident, someone rearranged the configuration of the buoys and marked each metal cable with a red flag. Alcohol was not a factor in this accident. Unable to contact witnesses of this accident.
