RedactedNarrative: On September 1, 2019 at roughly 17:35 Eastern time, KSP Post 4 dispatch informed us of a boat accident that occurred in the South Fork of Rough River Lake. Officer and I was close to the area of the State Dock when the call came in, and were informed that the accident location was around the Tanglewood Ln area of the lake, which was near the Indian Valley boat ramp. Dispatch advised that there was no injuries and all parties involved were still on scene.
  
  We arrived on scene around 18:23, and observed a red pontoon tied to the bank, which had severe damage to the starboard side of the vessel, and the dock was resting on the rock bank next to the pontoon. I immediately went to the red pontoon that had two occupants, a Operator (operator) and Subject1 (passenger), who were waiting on the wrecked pontoon. I first asked if everyone was okay, to which both parties said they were fine, and then I asked Operator what had happened. Operator stated that he was busy trying to take a picture of Subject1, who was sleeping, and was not paying attention to his direction of travel. The pontoon went in-between the rock bank and the boat dock, which the space was about as wide as the vessel itself. While Operator was telling me what happened, I could smell an odor of an alcoholic beverage on his breath. I then asked how much Operator had to drink today, which he replied he has about 2-3 drinks. After administering Horizontal Gaze Nystagmus (HGN), I was able to see four clues out of six, which made me believe that Operator was at or above the legal limit to operate a vessel. Officer then handed me the Preliminary Breath Test (PBT) to conduct on Operator, the PBT registered a .104 BAC. I knew Operator BAC was starting to decrease, so I instructed Officer to place him on our vessel while I took pictures of the vessel and damages. 
  
  I provided my e-mail information to the witnesses, for them to contact me for an electronic copy of the statement forms, and told Subject1 what was going to happen to her husband after we left. While taking pictures of the scene, one of the witnesses was telling me, they heard a loud crash and saw the red pontoon trying to leave the scene. When the witnesses hollered for him to come back, Operator turned around and tied up to the bank to wait for us to show up. They stated that the dock usually sits out about 20-30ft from the bank, and all of the walkway was smashed up on the bank. The cables holding the dock were separated from the wood and the pontoon had a lot of debris inside from the tree it collided with during the incident. The prop was above the water, showing damage, and the canopy attached to the pontoon was bent over, where it struck a tree limb. Officer and I departed the scene around 18:43.
  Operator was arrested for probable cause BUI and was taken to Breckinridge County detention center. On the way to the jail Operator made several statements of how he ruined their last weekend of boating and that this was a life changing incident.
