RedactedNarrative: Eight people went out fishing on the Snake River, boat capacity was 4 or 500 pounds.  Boat began taking on water after a wind storm started making white caps on the river. Operator tried to steer the boat to shore but the boat was full of water and it would not steer, so all eight occupants jumped out and swam to shore. One person did not make it and went missing. Boat was obviously overweight due to gear and number of persons on board.  THe operator was drinking alcohol.
