RedactedNarrative: Summary: On September 4th 2015 I responded to a vessel accident across from Lone Rock Beach. The accident involved a power boat vs. personal water craft (PWC), where the female of the PWC sustained injuries. The female was medically flown out due to injuries sustained in the accident. Witness statements were gathered from the vessel operator involved, family members on the beach, and family members on a vessel that observed the accident.
  
  INVESTIGATION: I arrived on scene which was located to the east side of Lone Rock Bay, where I observed a white power boat with a female laying on the back of the boat. The female was very pale and had her torso and legs covered up with towels. I instructed the vessel to go to Lone Rock ramp where first responders were awaiting their arrival. A rainstorm with strong winds ensued while we were en route to Lone Rock Beach which delayed the vessel from getting to the beach. I followed the vessel to Lone Rock launch ramp where park service ambulance was standing by to assess the female. Medics moved the female from the back of the boat and placed her into the ambulance. I was able to get a witness statement from the vessel that assisted the female.
  
  I went across the bay where the accident happened and made contact with the vessel involved. The accident scene consisted of a step angled sandstone slope to the waterline to the east, and lake on the west side. The sandstone slope extended to the north and came out to a shallow point. I identified the vessel operator as and his brother. OPERATOR1 was shaking and had trouble speaking clearly. OPERATOR1 stated that his vessel was disabled. I asked OPERATOR1 if he would be willing to  write a witness statement over the event. He agreed to write the statement. Ranger assisted me in side tying the vessel where we moved it to Statelin launch ramp so we could photograph the vessel out ot the water.
  
  STATEMENTS: OPERATOR1 provided a witness statement on the events that occurred. he was very upset about the event and having a difficult time focusing. He stated: Collision with unseen PWC impact to left front bow of my boat. I was unsure of cause of my impact and thought we had run aground. We were stopped of all motion after a hard right swerve. This is when we observed a blue and white PWC stopped and a rider in the water about 15 feet behind it. Other craft arrived to assist in one minute. The rider was hurt but not me or any passengers. I never saw the craft involved until after the collision. This report was written while being towed to ramp.
  
  On my interview with OPERATOR1 I asked him if he had consumed any alcohol. He stated that he did not have any today but he had consumed an alcoholic beverage the evening before. I had OPERATOR1 blow into a preliminary breath tester which registered a reading of 0.012BraC at 1744 hours. The legal alcohol limit is 0.08 BrAC for the state of Utah and within the boundaries of Glen Canyon National Recreation Area. Based on my interview with OPERATOR1 I determined his alcohol consumption was not a factor in this accident.
  
  The boat operator of the assisting vessel was identified. He stated: Upon our boat turning I saw, I saw the wave runner heading towards us at a 45 degree angle looking in out direction. At the same time the boat that hit her was heading parallel to us, same side of our boat as the wave runner. In an instant the boat hit the wave runner on the front starboard side. The boat rose up out of the water, the wave runner was hit at the front of it. It appeared that neither party saw one another even until impact. When I re-interviewed him later that day he stated the only injury she had sustained was to her head and face area.
  
  Witness2: I was standing on a rock above the water watching the tubers and boaters. I noticed my dad's wife riding on a wave runner. She and another boat were driving parallel to each other. They looked like they were pretty close from my perspective. I don't think either the
