RedactedNarrative: While out on Pathfinder Reservoir, Operator had just picked up two people off of tube and was attempting to make a turn with his boat.  As he was turning, due to high waves from wind, Operator had a large wave come over the front of his boat.  About 200-300 gallons of water came onto the boat dropping the back end of the boat into the water.  Upon this happening, Operator started handing all of his passengers life jackets as the boat was quickly sinking.  he stated that he did not grab a life jacket for himself.  At this point, everybody on board the boat jumped in the reservoir.  The boat then listed heavily to one side and sank with only the nose of the boat sticking out of the water.  All of the occupants of the boat were able to drift and swim to the Pathfinder dike on the south side of the dam.  The boat then drifted with the host out of the water to within 20 years of the dam and dike before completely submerging.  There were no injuries and no violations.  The accident was due to strong winds and large waves on the reservoir.
