RedactedNarrative: I, Game Warden was patrolling the Colorado River out of Laughlin, NV on August 31st at approximately 1440. I received a call from NV Dept. of Wildlife dispatch regarding a vessel accident that occurred adjacent to the Avi Casino. I responded to the accident scene.
   
  I arrived on scene at approximately 1508. The accident occurred on the Colorado River just outside the Avi Casino lagoon no wake area. Upon my arrival, the operator of vessel 1, was in a Fort Mohave ambulance. The operator of vessel 2, was on scene in the lagoon area. 
  
  I was able to speak to Operator1 prior to his transport to Valley View Medical Center in Fort Mohave, AZ.  Operator1 indicated, that he was operating vessel 1, cruising up river turning very wide from left to right. Upon turning to the left, Operator1 said he impacted a vessel. The impact was on the port bow of vessel 1, impacting the starboard bow of vessel 2. Upon impact Operator1 was ejected from the personal water craft over the bow of vessel 2. Operator1 sustained injuries from the handlebars of the personal watercraft as he was ejected. 
  
  Damage on vessel 1 is consistent with the impact on the port bow, there is cracked fiberglass from direct impact with another vessel. The rub rail on the port gunwale is damaged and distorted from the impact. The cowl adjacent to the handlebars is cracked, consistent with impact to the handlebars. 
  
  Speaking with Operator2, he indicated that he was traveling north on the river over 20 miles per hour. Operator2 noticed a personal watercraft on the river just north of him making very wide turns. Operator2 proceeded to try and overtake the personal watercraft on his starboard side. Operator2 committed to overtaking the vessel, upon doing so the personal watercraft impacted the starboard bow of vessel 2. Operator2 said the operator of the personal watercraft was ejected over the bow of vessel 2. Operator2 and his son helped the individual get to the lagoon. 
  
  Damage on vessel 2 is consistent with the impact on the starboard bow. Upon the initial impact vessel 1 was dragged down the starboard gunwale of vessel 2. There is white paint transfer from vessel 1, the rub rail is deformed and damaged. The rub rail towards the stern of the vessel had been deformed to the point it had popped the rivets and dislodged from the vessel. The batteries had also been dislodged from the location at the transom and had shifted considerably. 
  
  Operator1 sustained 4 broken ribs and a contusion on this left torso. Operator1 was transferred from the hospital in Fort Mohave to University Medical Center in Las Vegas, NV for further evaluation on the evening of August 31st.  Further evaluation of Operator1 indicated negative internal injuries. 
  Upon investigating this vessel accident both the operator of vessel 1 and the operator of vessel 2 are at fault.
