RedactedNarrative: Operator stated that they were drifting along the shore line, when he noticed the boat was taking on water.  Operator went to back of boat to turn on bilge pump and the boat sank.  Both occupants ended up in water and swam to shore.  The boat completely sank with only about 18" of the bow being visable above the water.  Occupants then walked about 200 yards back to the boat ramp area and were able to get a passerby to call for assistance.  Game Warden arrived and met with the boat operator and then proceeded to assist with the recovery of the boat.  The boat was towed back to the boat ramp by the assisting Game Warden.  The boat was then loaded on it's trailer.  Game Warden inspected the boat for possible caused of the boat sinking.  The only apparent cause factor found was the absense of the boat's plug.  The boat's operator stated that he had put the plug in the boat prior to launching.  The boat operator believed the plug  became dislodged from the boat for some unknown reason and resulted in the boat sinking.
