RedactedNarrative: On April 22, 2018 at approximately 1:03pm I, Game Warden, was standing in the fuel dock office at Las Vegas Boat Harbor when a male subject walked in and asked me if someone could take a look at his injured daughter who was still aboard his vessel tied up in a slip.  I called the National Park Service (NPS) Dispatch by radio and requested an EMT respond as I walked over to vessel.  I informed Subject and his daughter that an EMT was on their way.  
  
  I could see Victim was lying on the rear seat of the vessel with her legs on the seat.  She was crying and showed obvious signs of pain.  Subject was examining her right leg near the ankle.  I could tell her leg was starting to swell.  I asked Subject if he would like me to get some ice for the swelling and he affirmed.  I walked to the dock restaurant and retrieved a bag of ice and returned to the vessel, handed Subject the bag, and he applied the ice to the injured area.
  
  Shortly after returning with the ice, NPS Ranger''s, both EMT''s with the National Park Service arrived and tended to Victim.
  
  Subject explained to me that he and Victim had put their boat in at Hemenway Harbor and decided to head toward Hoover Dam.  They traveled around the west side of the Boulder Islands then headed east toward the Dam.  Subject stated he was cruising at approximately 15mph and Victim was seated in the open bow of the vessel. They were traveling near the Hemenway Wall (approximately 36.03444, 114.73138) and Victim stood up in the open bow.  A few waves had bounced off the wall from a distant vessel and Subject crossed through the wake.  The bow of his vessel moved up and down with the waves and Victim got tossed up and down making contact with the vessel floor, hitting her right foot violently on the floor.  She fell to the vessel floor.
  
  Subject put the vessel in neutral and picked up Victim and brought her to the rear seat of the vessel.  He opened up the ice chest, took out the food, and placed her right foot/leg into the ice.  He then drove to the Las Vegas Boat Harbor where he contacted me.
  
  NPS Rangers discussed the injuries with Subject.  He decided to self-transport his Daughter to the Boulder City Hospital for further evaluation.  Ranger provided a wheeled chair and we helped Victim to Subject''s truck, where she was placed into the back seat and transported to the Hospital.
  
  Later that evening I observed Subject recovering his vessel at the boat launch.  I asked how Victim was doing and he stated she was doing better, however, she did sustain a broken Tibia.  I helped Subject load his vessel on the trailer, wished him and his daughter well, and cleared the scene.
