RedactedNarrative: On 06/13/2020 I responded to Holter lake for a reported capsized boat. I arrived on scene at the BLM recreation site off of Beartooth Road to a Malibu ski boat resting upright close to shore. I checked in with the Wolf Creek Fire Chief who was rendering medical to the boat's occupants. After accounting for all six occupants onboard, I took the operator of the boat to my patrol vehicle for an interview. 
  
  The operator stated he was the owner of the boat, and had five occupants with him in the boat. The group was recreating on Holter Lake before the incident occurred. The operator stated he was driving the boat back to ramp due to the high winds that were present on the lake that day. While headed for the boat ramp, a wave crested the bow of the boat and filled it with water. The operator then accelerated trying to bring the bow of the boat up above the water. 
  
  After accelerating, water flowed back towards the stern where the five other occupants were sitting. The boat then capsized and began to roll upside down. The operator jumped overboard from the drivers seat. Some of the other occupants were trapped underneath the boat when it rolled. Bystanders came to the aid of the occupants that were trapped under the boat. The operator swam to the South towards a rocky peninsula, while the other occupants with help from bystanders made it to shore on the North end of the bay. Once everyone made it to shore, the operator and other bystanders were able to re-right the boat and drag it to a dock. 
  
  The weather on 6/13/2020 made for dangerous boating conditions on Holter Lake. High winds created rough waters with white capped swells. The operator stated he had just bought the boat ten days prior to the incident. This was the first time he had operated the boat involved in the accident. When asked if he had consumed any alcohol that day, he stated he only drank one beer hours earlier. While sitting in my patrol vehicle I was able to detect the odor of an alcoholic beverage emitting from OPERATOR 1. 
  
  SERGEANT 1 and Game Warden arrived on scene at the end of my interview. SERGEANT 1 re-questioned OPERATOR 1 on the amount of alcohol he had consumed. OPERATOR 1 told SERGEANT 1 he drank more than one beer. When asked to take a preliminary breath test (PBT), he refused. The operator did consent to SERGEANT 1 administering a test to check horizontal gaze nystamgmus (HGN). The operator did show signs of impairment during the HGN test. I spoke to SERGEANT 1 after the test and we concluded that the operator likely was under the influence of alcohol to a degree, but was not showing any significant indicators he was at or above the legal limit. With no implied consent and the refusal to take a PBT, there was nothing to further a boating under the influence investigation.  
  
  During the interview, other occupants of the boat were being checked by medical. I confirmed with the ambulance staff that no one was being transported to the hospital. SERGEANT 1 and I ensured there were sober drivers among the group who could drive everyone home. All six occupants left the scene in a personal owned vehicle. 
  
  After following up with two of the occupants, I learned both were seen by a doctor after the incident and were both diagnosed with a concussion. One also tore her knee which she previously had surgery on months before the incident. Both also said they injured their ribs during the incident.
