On 7/16/11 at approx 1509hrs i was patrolling and observed a boat go under water just across from bartlett flats and bills hill. I observed the front of the boat pointing towards the sky. As i observed the boat number and called it in it went completely under water. I rescued 6 people into my boat and returned them to shore. There were no injuries. According to the operator he was stopped and was about to change skiers when 2 boats went by and the wake from those vessels came over the side of his vessel and it began to sink immediately. I advised he would have to have the vessel removed from the lake as his own expense. The operator stated that his large red and yellow raft was still attached and floating above the sunken boat. I then went to that location to get gps coordinates. Upon arrival at the scene i saw 2 individuals in the raft that was now attached to another vessel. They said they thought it was a lost raft and had cut the rope. I told them that if it was still attached to something it was not free floating and thus not able to be taken, i also informed him that by cutting the rope he had hindered the investigation of a sunken boat. They returned the raft to the owner of the sunken vessel. No citations were issued.
