Three occupants were in a canoe paddling in a whitewater environment. They were headed downstream when the canoe hit a rock causing the canoe to capsize. The three held onto a rock in middle of river and were rescued by fire department personell. All passengers refused medical treatment at first but later one complained of pain in both ankles and was transported to a hospital. The river had a high flow rate at the time of the accident and was a contributing factor. The main operator of the canoe was experienced.
