RedactedNarrative: Ranger and I responded with NPS Rangers on a boat accident involving a boat running aground.  We arrived to find two men on shore and a man and a woman on the boat.  The woman identified herself as a nurse that came to assist.  I asked who the operator was and the man on the boat raised his hand and the woman also signaled that he was the operator.  I asked who was the most seriously injured and she signaled again to OPERATOR and said he had a possible broken leg.  I responded to him and asked if it was ok for me to look at his injuries.  NPS Ranger was right behind me and attended to one of the men on the shore and I had the nurse place a 5X9 dressing on the other man who had a laceration to his face.  I quickly checked OPERATOR's right ankle and leg and found no obvious fractures or bleeding but significant swelling.  I checked for movements in the toes and capillary refill I told him to keep the foot elevated as I then continued to check for other injuries and asked OPERATOR what other injuries he had.  He said his wrist and nose.  I had OPERATOR place a 4X4 gaze on his nose to control bleeding from a laceration approximately one inch long.  I checked the left wrist and found it to be swollen with small lacerations that had already stopped bleeding.  I took a pulse rate at 18:15 and it was 116 I took it again at 18:30 and it was 120.  While checking OPERATOR I could smell the distinct odor of alcoholic beverage on his breath and his eyes were constricted.  I performed FST's on him of horizontal gaze and nystagmus  and found he had lack of smooth pursuit, distinct nystagmus at maximum deviation, and onset prior to 45 degrees.  I informed him that I believed him to be under the influence of alcohol and intended to charge him with DUI.  I then had him blow into a PBT which confirmed alcohol in the system.  I did not have him perform any other FST's due to the accident.  I remained with OPERATOR and helped transported him and the other passengers to the Bullfrog Clinic.    While transporting OPERATOR he said "It's my total stupidity" and "It's not like I'm going to say it wasn't me" in regards to him driving under the influence.  I had him checked by the staff for any immediate medical needs then continued with the DUI.  OPERATOR consented to a breath test and blew a .127.  I completed the DUI booking process and released OPERATOR to his friend.  The boat involved was impounded by Kiteley's in Hanksville.  Ranger stayed behind with the vessel for the impound.  My original citation I only wrote in for a DUI under code 41-6a-502.  I returned to the clinic as OPERATOR was leaving and wrote in DUI code 41-6a-503 (2a) which includes causing serious bodily injury.  I also wrote in 73-18-15.1(1) improper lookout, and 73-18-15.1(8) failure to maintain safe speed and distance to avoid a collision.  I informed OPERATOR of the changes and had him resign his copy of the citation.  He thanked us for coming and helping them out.
  
  When asked what happened before the crash OPERATOR said that they were on their way back to Bullfrog and must have taken a wrong turn.  The site of the crash was a small side canyon approximately 100 yards or less.
