RedactedNarrative: INITIAL CALL
  On July 29, 2018 at 7:07pm, while on duty within Glen Canyon NRA, I received a call from park dispatch of a 44yo female who had sustained a head trauma injury aboard a vessel coming into Stateline Launch Ramp. 
  
  At 7:24pm a Moomba Mondo ski boat arrived at Stateline Launch Ramp. Classic Air ambulance ALS helicopter arrived on scene. EMS personnel contacted said vessel and observed a 44yo female lying supine on a vessel seat, she had sustained severe head trauma from an impact wound to the right side of her head. I applied a c-collar onto the patient and loaded said patient onto a backboard. The patient was transported via stretcher to Classic Air Ambulance helicopter. The patient was intubated and wound care rendered on scene prior to being loaded via backboard into the helicopter. At 8:02pm Classic Air Ambulance helicopter departed the scene with 44yo female aboard.
  
  INVESTIGATION
  The operator of vessel1 stated that he had drank several beers throughout the day. Furthermore, the odor of an alcoholic beverage emanated from within the vessel. Ranger conducted Standardized Field Sobriety Tests (SFST) on him with negative results. 
  
  The group had been camping on Lake Powell since the afternoon of July 27, 2018. OPERATOR2's Supra SA450 ski boat ran out of gas on the afternoon of July 29, 2018. At approximately 6:00pm after packing up their camp, the group decided to rear tow vessel from around Buoy 18 to Stateline Launch Ramp. OPERATOR1 operated tow vessel, with two people as passengers. OPERATOR2 was aboard towed vessel.
  
  During the return trip, in the main channel between Buoy 18 and Buoy 14, the vessel in tow was struck by a large wake from a passing tour boat, which swamped the vessel causing it to take on water. OPERATOR2 stated that while in tow he began bailing water out of his vessel with a bucket. The powerless swamped vessel weighed down the tow line which caused the tow hook to snap. The tow rope, with hook attached, sprang forward into tow vessel and struck occupant, who was seated in the rear seat, on the right side of her head. OPERATOR2 jumped out of vessel and swam to vessel, which he boarded. With all involved aboard vessel, they called 911 and proceeded to Stateline Launch Ramp. Vessel was left adrift at an undetermined location in the main channel between Buoy 14 and Buoy 18. On July 30, 2018 at 10:03pm, Ranger located vessel at the shoreline near Buoy 21. Ranger secured said vessel to the shoreline and contacted Aramark Executive Services to recover the vessel. Neither vessel sustained any damage related to the accident.
