RedactedNarrative: Three occupants of watercraft had been fishing on river. The watercraft had an electric trolling motor (54 lbs of thrust), which was not in use at time of the accident. The watercraft was floating down the river, which was high and had a strong current, when they came across 2 oak trees which were completely blocking the river. All three occupants grabbed a hold of the branches to slow the boat down. They tried to maneuver the front of the boat through the trees and in doing so, the water started flowing over the side of the boat, causing it to capsize. The operator and one passenger hung on to the oak trees. The other passenger hung on to the boat as it floated away. The operator and passenger hanging on to the tree managed to get to calmer water and out of the river. The passenger who floated with the boat was located about 1000 feet downstream, 50 feet from shore holding onto a tree. Rescuers threw him a life jacket, but he couldn't get it on. They got him to shore, where he was taken to the hospital with non-life threatening injuries (scrape on the arm from hitting debris in the water). The watercraft only had 3 Type IV cushions on board, so none of the occupants had been wearing life jackets at the time of the accident. The watercraft was not recovered.
