RedactedNarrative: On Friday September 2, 2016 at approximately 10:45 a.m. Game Warden was notified of a vessel fire near Fisherman''s Access and we responded.  We arrived at Fisherman''s Access at approximately 11:04 a.m. 
  
  Upon arrival, a Riverside Resort water taxi was bringing subject to Fisherman''s Access and I made contact with him.  Subject stated that he was the operator and sole occupant of the vessel reported to be on fire (Vessel 1, V1). 
  
  Subject stated that he launched V1 out of Fisherman''s Access and V1''s engine died after starting it.  Subject started V1 again and moved it north of the boat launch towards the public dock.  Upon reaching the dock, V1 backfired and the engine stopped again.  Subject opened the engine compartment to investigate and saw a flame near the battery in the port corner towards the stern.  Subject used his fire extinguisher on the fire but the fire only grew larger.  Near the Riverside Resort, Subject jumped from V1 into the water to avoid injury and he boarded another vessel.  V1 continued to float down river and an unknown number of personal watercraft tried splashing V1 to extinguish the fire.  During the questioning of Subject, V1 was pulled to the boat launch of Fisherman''s Access by Bullhead City Fire Department.
  
  Subject2 was on scene and stated he was driving the vehicle that launched V1.  Subject2 stated he went to park his truck and did not see the events that led up to V1 catching fire.  Subject2 stated he came back down from parking the truck and saw V1 with its engine compartment open and Subject attempting to extinguish a fire.  Subject2 stated this attempt was unsuccessful, the fire grew larger, and V1 floated down stream.
  
  Nevada Department of Wildlife was on scene and stated V1 was launched at Fisherman''s Access and he saw V1 smoking.  He stated Subject attempted to extinguish the fire but was unsuccessful.  He saw Subject leave his vessel and then contacted Warden and 911.
  
  Damage of V1 appeared consistent with a vessel fire from the engine compartment.  Damage was estimated at $4000.
  
  Damage of V1 and statements indicate that the fire aboard V1 was caused due to mechanical failure in the electrical, engine, and/or fuel systems.  
  
  Photographs were taken of V1 (attached).
