RedactedNarrative: At approximately 1534 hours, I (Game Warden) along with Game Warden received a call concerning distressed boaters on the north end of Jackson Lake. The NPS rangers had already responded to the scene where a boat had run aground in the shallow end of the lake, disabling the vessel. At the place of the accident, the water was very shallow and with spring runoff the color of the water was dark brown meaning no visibility. 
   
  There were two individuals, later identified as Occupant and Operator, on the boat when the accident occurred. The boat in the accident was Wyoming registered boat 6939BB a 23ft 1984 Chris Craft. The boat held current Wyoming registration for 2014 under a different name. Alcohol found on the boat included a fifth of Patron tequila consumed from the bottle, around 3/4 of a fifth bottle consumed of Kettle One Vodka. In addition there were several empty beer cans of Blue Moon. Inside the boat several blood spots were present inside the cabin area, the dashboard of the boat, and around the driver and passenger area. The prop of the boat was completely destroyed, showing they had run the boat aground. The lower unit of the inboard/outboard motor was paint chipped and a significant amount of new wear could be seen. The tachometer of the vessel was stuck at 900 rpms and the speedometer was stuck just below 10 mph, suggesting that the boat ran aground at this speed in order to make the gauges stick into place. On the front starboard side of the boat there were small deep cracks found in the boat’s fiberglass hull. It is uncertain if these cracks were the result of the accident or if they were present before the accident. There was not enough evidence found in the boat to be certain as to which part of the boat the boaters struck during the accident. Due to injuries inflicted during the accident, damage to the boat, and the amount of alcohol found on board the vessel, we interviewed both individuals to determine who had been operating the boat at the time the accident occurred. 
   
  We could smell the odor of an alcoholic beverage on both Occupant and Operator’s breath. Occupant claimed that Operator had operated the watercraft all day, while Operator stated that he and Occupant had both operated the boat and that he could not remember who was driving when the accident took place. Operator also mentioned that they had driven aground several times that day. I explained to Occupant and Operator, since neither individual claimed to be the operating the vessel at the time of the accident, I needed to ensure that both men were able to operate the watercraft safely and not under the influence of a controlled substance. Both Operator and Occupant refused to perform SFSTs. Based off the evidence of alcohol use on board the watercraft, their statements, and the detection of alcohol on Operator and Occupant's breath, both men were placed under arrest for boating under the influence of a controlled substance and for reckless operation of a watercraft. Operator and Occupant were read the Wyoming Game and Fish Advisement to Search form and paramedic with Grand Teton National Park drew Operator and Occupant's blood to prevent the loss of any evidence of a controlled substance in their bodies. Operator was then transported by NPS rangers to the Teton County Detention Center. Occupant was transported by ambulance by NPS rangers to the Teton County Medical Emergency Room. At 20:34 hours I received a call from the NPS rangers stating that Occupant’s injuries were too severe to be treated in Jackson, and that Occupant had to be transported to Idaho Falls or Salt Lake City to seek the proper medical attention. At approximately 21:00, I issued Occupant must appear citations for the previously mentioned violations and released him from my custody, so that he could seek the proper medical attention.
