RedactedNarrative: Operator was operating a Seaswirl Runabout (WN7486LB) in reverse near the dock at the East Fernan Boat Launch on Fernan Lake. While Operator was traveling in reverse he got his propeller wrapped on a steel cable, that was attached to an anchor on the dock. The vessel started taking on water in the engine compartment so he attached a water pump and began to pump the water out of the vessel as it began to sink from the rear. Operator put a new battery in and continued to pump the water from the boat. 
  
  Operator then left the boat at the dock and abandoned it. Operator claimed he left it there with the intent to get tools at a later time and get the boat unstuck. Operator said it was dark and that the incident occurred on 05-12-17 sometime when it was dark outside. I responded to area for a report of an abandoned vessel the next morning on 05-13-17. 
  
  Upon my arrival Operator's vessel had completely sunk and the I/O was resting on the lake bed. There was debris floating in the lake and hazardous materials, gas and oil leaking into the Lake. Kootenai County Fire and Rescue responded and cleaned the hazardous material. I had the vessel removed from the waterway. 
  
  The vessel was not registered to Operator and we could not prove he owned the vessel so it was towed back to the Sheriff's Office for safekeeping. A crime report was completed for Failing to notify Law Enforcement of a reportable accident. No injuries occurred. The dock's anchor was broken from the dock and the cable was no longer attached to the dock. Registration for the vessel placed the value of the vessel at 10k dollars. 
  
  The damage occurred during this incident is close to that as the engine is likely destroyed and the interior of the boat is destroyed.
