RedactedNarrative: On June 29, 2020 at approx. 4:18 pm, while exercising my duties as a law enforcement office inside Glen Canyon NRA, I received notification from Park Dispatch of a capsized vessel in Wahweap Bay near the Castle Rock Cut. All parties were reported to be wearing PFD'; however, 2 individuals were unaccounted for.
  
  Ranger 2, Ranger 3, and I, Ranger 1, responded in NPS patrol vessel V258 from Wahweap Government Dock at approx. 4:21 pm. Ranger 4 had visual confirmation of the location of the vessel in distress from the top of the Wahweap Boat Ramp and provided direction. While en route, we requested NPS Patrol plane, 2PS, launch and aid in search efforts.
  
  The weather at the time was approx. 100 degrees, wind gusts between 25-35mph, and swells ranging from 2-4ft.
  
  On Scene:
  At approx. 4:25pm, we arrived on scene, and were flagged down by 2 jet skis. I observed one fully cpasized vessel with most of its black hull below the surface of the water. Later upon recovery, the vessel was identified as a 2017 Bayliner 195DB 19' ski boat. We contacted a pontoon boat with 8 passengers of the capsized vessel safely on board. They reported that they were missing one 40-year-old female who was last seen aboard the vessel wearing a yellow PFD, female later identified as Injured, by her driver's license.
  
  We began visually scanning the surrounding are and advised nearby bystander vessels to begin searching for the missing female. Ranger 2 positioned V258 closer to the capsized vessel. Ranger 3 and Ranger 2 confirmed my observation, as we heard a female yelling "help me" from inside the sinking hull of the capsized vessel. At approx. 4:30pm, we advised park dispatch that we had located the missing party, and she was trapped underneath the vessel.
  
  We called out several times for her to swim out from the vessel and that we would be closer to retrieve her. We heard no response and observed no attempts. I extended a boat hook beneath the water surface and called out for her to grab onto the hook so that we could pull her from underneath the vessel. Again, I heard no response and observed no attempts to grab the boat hook.
  
  A brief discussion of rescue options ensued, to which Ranger 2 decided that he would enter the water to retrieve the trapped female. I agreed that this was our own viable rescue option at the time. A good samaritan from the neighboring pontoon boat provided diving goggles to Ranger 2. Ranger 2 removed his duty gear, donned the goggles and entered the water at approx. 4:31pm. Ranger 2 entered the from the bow of vessel 258 and approached the starboard side of the overturned vessel. He submerged himself for a short period of time and emerged and began shouting instructions for the patient. Ranger 2 submerged a second time, and emerged with the patient, swimming with her in his grasp away from the vessel. Ranger 2 and the patient swam for a short distance until they were able to stand, Ranger 3 and I assisted then onto vessel 258.
  
  Aboard the vessel, the patient was observed to be shivering uncontrollably and presenting with difficulty breathing. Ranger 3 administered high flow supplementary oxygen via non-rebreather mask at a rate of 15 liters per minute. I wrapped the patient in a sleeping bag and sat next to her with my arm around her for provided warmth. I placed two external heat packs under her arm pits. The patient was alert to person, place, time, event and was able to independently maintain a patients airway. Her skin and extremities showed signs of adequate perfusion, and she did not complain of any trauma or injury.
  
  At approximately 4:43pm, V258 arrived at Wahweap Main Ramp. The patient was placed in warm, dry clothes and seated in the cab of the Utah DNR Officer's patrol vehicle with the heater turned on. Ranger 3 continued to monitor the patient and reported that her condition remained stable. Page Fire Dept. Medic 10 arrived on scene and patient care was transferred to the paramedic staff.
  
  Investigation:
  At approx. 4:50pm, I contacted the vessel operator, identified as Operator, by his driver's license. Due to a language barrier (unable to write English, Spanish as a first language) I conducted a verbal interview with Operator, recorded on BWC. Operator stated the following:
  
  Their party of 9 got on the water at approx. 10:00am, aboard a rental vessel. There was a case of beer aboard the vessel, but only 2 members of the party had consumed alcohol during the day. Operator stated that he does not drink and showed no indications of alcohol impairment. At around 4:00pm after entering Wahweap Bay through the Castle Rock Cut, their vessel began taking on water, due to high winds and 2-4 foot swells. There were 9 total people aboard the vessel, "at least 5" were seated in the bow. After several large swells crashed over the bow, Operator activated the bilge pump and instructed the vessel passengers to move to the back of the boat. Operator stated that these actions were made too late as the vessel began taking on large quantities of water. After a short time, the vessel began to capsize. The vessel occupants, all of which were wearing PFD's, jumped into the water. A good samaritan in a blue pontoon boat, arrived to assist. 8 members of the party boarded the pontoon boat; however, Injured was missing. They immediately contacted park dispatch.
  
  A brief statement given by the unidentified operator of the blue pontoon boat, indicated that he witnessed an already capsized vessel and 8 people wearing life jackets in the water.
  
  I spoke with an employee of rental company. I provided him with a description of the vessel's last seen location (approx. 100-200 yards south of the Castle Rock Cut and approx. 20-50 ft off the shoreline of Antelope Island, on the Arizona sice of the Utah-Arizona state line).
  
  DISPOSITION
  Due to on scene verbal statements, I determined that Operator had little to no vessel operating experience (0-10 total hours) and was unprepared to operate a vessel in such weather conditions. The overloading of the bow of the ski boat, combined with 2-4 ft swells, and a lack of operator experience; led to the capsizing of the vessel. Due to the language barrier and long-term water exposer by the party, I was only able to identify 5 of the 9 vessel occupants, as 4 members of the party departed the scene shortly after reaching Wahweap Main Ramp. 
  
  I spoke to Vessel Owner via telephone. Vessel Owner provided me with vessel documentation. I informed Vessel Owner that it was his responsibility as the vessel owner to recover the vessel and provided him with contact information for Aramark Exec. Services. On 6/30/20 at 8:41am, Vessel Owner notified me that the vessel had been recovered. Due to the vessel having completely capsized, it was considered a total loss of property.
