RedactedNarrative: The victim was operating his recently purchased pontoon boat with three passengers on board. He stopped the boat on the south end of the lake. The anchor was lowered in deep water, although the boat continued drifting. 
  
  The victim swam from the boat to relieve himself. The three passengers remained on the boat as it drifted away from the victim. The victim started struggling, and then became fully submerged face-down in the water for approximately one minute. 
  
  The three on the boat were unfamiliar with it's operation. They eventually maneuvered back to the victim and it took approximately 3-4 minutes to pull him back onto the boat. CPR was started as soon as he was on the pontoon boat. The male passenger was able to get the boat to the public access, where lifesaving measures were continued. The victim was later pronounced dead at the scene. Lifejackets were not being worn. There was a small amount of alcohol in the victim's system.
