RedactedNarrative: On March 27, 2016 at approximately 12:50 hours I, Game Warden was preparing to launch my boat at government dock at Las Vegas Boat Harbor on Lake Mead when I heard community ambulance contact National Park Service (NPS) dispatch over the radio. NPS dispatch advised community ambulance to meet park rangers at Boulder Harbor concerning a medical call. I contacted NPS dispatch and asked if the medical was related to a boat accident. NPS dispatch stated that it was related to a boat accident involving a prop cut. I advised NPS and Nevada Department of Wildlife (NDOW) dispatch that I would be in route to Boulder Harbor.
  
  I arrived on scene at approximately 12:58 hours. The vessel was tied to the dock. NPS park rangers were on scene and the victim, was already loaded in the ambulance. Park Ranger had begun the initial accident investigation.  Park Ranger stated that the vessel had all necessary safety equipment. Park Ranger stated that he had already photographed the vessel prior to my arrival.  Park Ranger informed me that the operator had stated that he had one beer earlier in the day.
  
  I interviewed the operator who stated that they had left the dock at approximately 11:50 hours and were headed toward Hoover Dam. He stated that they were approximately 50 yards from the red navigation buoy on the south east side of Boulder Islands traveling at approximately 20 mph. 
  
  He stated that Victim was kneeling on the front seat in the bow of the vessel facing toward the front of the vessel. Operator stated that he pulled back on the throttle to slow the vessel down. Victim lost his balance and fell forward over the bow into the water. Operator stated that he didn''t know what to do and grabbed the lanyard for the kill switch of the vessel. He stated that Victim popped up behind the boat and stated that the engine had hit him. Operator jumped in the water to help Victim back to the vessel. The occupants immediately called 911, wrapped Victim''s injured arm in a towel and headed back to Boulder Harbor to meet medical personnel. 
  
  I asked Operator how much alcohol he had drank that morning. Operator stated that he had one beer between 10:30 and 11:00 hours. I had Operator perform the horizontal gaze nystagmus test. Operator showed a total of 3 clues where 4 clues is a sign of impairment. Operator provided a preliminary breath test sample with showed a BAC of 0.041.
  
  Victim''s injuries consisted of a large laceration to the right bicep near the elbow, multiple small lacerations to the front and back of his torso, and a laceration to the right leg near his knee. Victim was transported to UMC to receive medical care.  
  
  On April 4, 2016 I called Victim to do a follow up interview. Victim stated that he was riding in the bow of the vessel kneeling on the seat to feel the breeze in his face. He stated that the vessel suddenly slowed down throwing him forward over the bow of the vessel. He stated that he did a flip forward while going over the bow and ended up in the water facing the bottom of the lake with his head toward the stern of the vessel. He stated that he was calm and felt that the vessel would just pass by him. 
  
  He stated that as the vessel passed over the top of him the lower unit of the vessel struck him. He stated that he then popped out behind the vessel and began calling for help when Operator jumped in the water to help him back to the vessel. Victim told me that the doctors stated that the laceration to the right arm went through the muscle and cut into the bone causing some nerve damage. Victim received staples for both the incision in his right arm and right leg. Victim sent me a photo of his injury to his right arm.
