RedactedNarrative: Operator was on a PWC. Witness saw him traveling at a high rate of speed and hit a wave.  PWC rolled and the operator ended up in the water and began screaming for help.  Two nearby pontoon boats assisted with getting him onto their boat.  Victim complained of difficulty breathing and then went unconscious.  CPR was performed and continued once they reached North Pool ramp.  Careflight pronounced the victim deceased.  The PWC being operated was removed from the area so I didn’t obtain any information-it is to be brought to Caesar Creek today May 30
