RedactedNarrative: On August 25th, 2018 I, Game Warden, was patrolling the Laughlin, Nevada area. At approximately 1336 hours dispatch called me and advised of an injury vessel collision at the Avi Casino with a report of a woman who had a severed hand. At approximately 1336 hours I was enroute to the Avi Casino via land. Game Warden was also enroute.
  
     I arrived on scene at approximately 1401 hours. Mohave Fire was also on scene. Once on scene I began the investigation. I made contact with security. Security advised both vessel 1 (V1), bearing California registration, and vessel 2 (V2), bearing California registration, were secure on the shoreline. Security was on scene with the operator of V1. Security had collected witness statements from Operator1.
  
     While on scene I interviewed Operator1. Operator1 stated that V1 had stalled, causing off throttle steering lost. Operator1 advised V1 began to veer to the right which caused V1 to collide with V2. Operator1 advised that he tried yelling at Operator2 to get her attention prior to the collision. I asked Operator1 what the approximate speed of V1 was prior to the collision. Operator1 advised V1 was travelling approximately 20 miles per hour (MPH) after the engine stalled. I asked Operator1 if he had anything to drink. Operator1 advised he had consumed two beers before noon prior to the collision. I requested Operator1 sit on a bench so I could conduct horizontal gaze nystagmus on Operator1. Operator1 did not display any clues of impairment.
  
     While on scene security advised me there was a video recording of the collision in the security office. Security maintained custody of Operator1 while I went to the security office to review the video recording. The video recording correlated with what was stated by witnesses. I requested a copy of the video recording for the case file.
  
  Conclusion
     V1, operated by Operator1, was travelling south on the Colorado River near the Avi Casnio. V1 reportedly stalled, causing off throttle steering loss. V1 veered to the right. The bow of V1 struck the port side stern of V2.
     V2 was travelling south on the Colorado River near the Avi Casino. V2 was idling near the launch ramp when it was struck. The port side stern of V2 was struck by the bow of V1, striking Operator2, causing her to be ejected. Operator2 was removed from the water by her husband and taken to the launch ramp.
     V1 appeared to have scratches in the gel coat on the starboard side bow, near the keel. The estimated cost of damage to V1 is approximately $100.
     Based on the investigation, Operator1 was found at fault for causing the collision.
