RedactedNarrative: Three individuals were in a two-seater canoe fishing on the lake. They were approximately 100 yards NW of the eastern peninsula of the lake when the canoe capsized, putting all three occupants into the water. The two passengers resurfaced, but the operator didn't. Witnesses near the capsized canoe came to help. One witness attempted to grab the operator, who was still submerged, but was unsuccessful. He got the two passengers into his boat because they were visibly struggling to stay above water. At this point, the operator had slipped below the waterline to where he was no longer visible to witnesses. The Sheriff's Office personnel arrived on scene and began search and rescue attempts, but were unsuccessful. The dive team arrived and began to search, utilizing divers and remote operated vehicle (ROV). The operator was located by the ROV at about 2248 hours and a diver was sent in to recover him. The passengers had no injuries. Life jackets were not being worn, nor were there any in the canoe. There was no damage to the canoe. The passengers didn't know what caused the canoe to capsize. Alcohol was not a factor.
