RedactedNarrative: On Wednesday, July 4th, Officer and I checked the state ramp of Rough River Lake to get an idea of the boat traffic in that area. When we approached the ramp by vehicle, two pontoons were coming into the ramp area towards the courtesy dock. One pontoon had just dropped off what appeared to be several kids, and a woman on the pontoon waved her arms in a distress type manner. When I got out of the truck and headed to the courtesy dock, a male was standing by the dock watching the people unload from the pontoons. Operator, was the male, and when I asked him what was going on, Operator stated "my boat sank." I made sure that all occupants of the sunken vessel were accounted for and that there were no injuries. Operator stated that the boat was tied up to the rock wall, and his keys to his vehicle were on the rocks next to where the boat was tied up. Operator got into our vehicle, while I told the other occupants of the sunken vessel, to stay in the shade and someone from the state park would pick them up in a van. 
  Officer, Operator, and I drove up to the state park resort, and asked if they could get a van to pick up the occupants of the sunken vessel and that everyone was okay. Officer and I took Operator to get his keys on the rocks near his vessel, and we were able to see Operator’s vessel in the water that was 3/4 submerged. The bow of the vessel was visible, and the registration numbers were clearly visible.
  Once we returned back to the state park resort, Officer gathered all witness information, along with Operator's information and statement. Operator, and 8 other occupants, were on his vessel, they left the state ramp and went towards the location where the boat went under. Operator and witnesses stated that they went swimming for about 30-40 minutes, when all individuals got back onto the vessel from swimming they noticed the stern of the vessel had taken on a lot of water. Operator said he knew the boat was going under and told everyone to grab a PFD and any valuables, and hop back into the water. Two pontoons noticed that the boat was going under and came over to recover all the occupants.
  We asked Operator if the boat had any leaks or cracks in the hull that he knew of, to which he replied "no". Then when asked about putting the plug in prior to launching the boat, Operator was unsure and stated he thought the plug may have come out when they were riding to the swimming spot. Officer and I left the resort to meet up with Operator at the state ramp, by our vessel, so we could go out to the site and recover the items that were floating in the lake. 
  Once we recovered majority of the items, we took Operator back to the state ramp and gave him the contact for vessel recovery on the lake. We informed him that he would need to contact the Core and see what timeline he has to recover his vessel, or they might file charges on him.
