RedactedNarrative: On 08/06/2018 at approximately 0354 P.M. Marine 5 was dispatched to an injury boat accident. The accident occurred in Mitchell Bay and the vessel and its occupants went to the 3rd Street Docks. We contacted the reporting party at Kootenai Health. Operator was towing victim on a knee board behind the vessel. Victim cleared a wake behind the boat and nose dived into the opposite wake. When the boat turned around to retrieve him they noted he was bleeding and immediately pulled victim aboard. He suffered a 4 to 6 inch laceration on the left side of his neck. At the time we took the report, the passengers of the vessel were no longer around so their information could not be obtained.
