RedactedNarrative: While on water patrol on 09/16/2017 at approximately 1557 hours (MST), just off Lone Rock Beach on Lake Powell, Ranger and I observed a personal watercraft (PWC) moving in circles near two swimmers in the water. As we moved our NPS vessel closer, it appeared that the two swimmers had been ejected from the jet ski. Operator repeatedly swam toward the circling jet ski attempting to stop its motion and/or reboard the vessel. We ordered him to stay away from the vessel, but he did not comply.
  
  At one point, OPERATOR reached the PWC and then lost his grip on it. This caused the PWC to move rapidly toward the PWC's passenger, an 11 year old juvenile female, who was floating in the water nearby. I moved our NPS vessel between the juvenile and the PWC and Ranger reached over and pulled the PWC's lanyard out of the kill switch, stopping the vessel.
  
  The female juvenile was screaming she could not feel her leg. Ranger and I lifted her into our NPS vessel and I began an EMS assessment on her. OPERATOR reached the PWC, which was laying against our vessel and repeatedly attempted to board it. He failed in each instance. Ranger directed him to the aft of our NPS vessel where I had set up the vessel's swim ladder. OPERATOR was able to climb aboard via the ladder. Ranger noted that OPERATOR was unsteady on his feet and he detected the smell of an alcohol-containing beverage on OPERATOR's breath.
  
  The juvenile was complaining of sharp left lower leg pain. I directed Ranger to move slowly toward Lone Rock Beach where the juveniles mother was located. We took the juveniles mother aboard and I treated the juvenile by applying a stirrup splint to her left leg. We transported the juveniles mother, the juvenile patient and OPERATOR to Stateline Launch Ramp where the juvenile and her mother were transported by NPS ambulance to Banner Page Hospital. She was subsequently medically evaluated and released.
  
  OPERATOR stated that while operating the PWC he had "hit a wake" and fell off the PWC. Seated battery SFSTs were conducted on OPERATOR by Ranger. Along with a positive PBT reading, enough clues were obtained during the SFSts that OPERATOR was arrested for BUI. He was subsequently administered a breath alcohol test by Ranger on an intoxilyzer 8000. At 1740 hours, OPERATOR's blood alcohol content was 0.093 g/210L and at 1747 hours was 0.091 g/210L on the second test. OPERATOR was then booked into the Coconino County Detention Facility and cited under:
  
  
  36 CFR 3.10 (a)(1) BUI
  36 CFR 3.8 (b)(9) Reckless operation of a vessel
  36 CFR 3.9 (b)(2) Failure to wear a lanyard
  36 CFR 3.10 (a)(2) BAC>0.08
