RedactedNarrative: Three occupants were bow fishing when the drain plug on their boat malfunctioned. The boat flooded with water causing the boat to partially sink. Two passengers swam to shore and called for help. The operator of the boat could not swim and had to be rescued by a MN DNR Conservation Officer with a boat. He had been in the frigid water for almost 45 minutes clinging to the boat. The passengers refused medical transport. The operator was transported to the hospital for treatment. Life jackets were not being worn. There was no damage to the boat.
