RedactedNarrative: Watercraft (a kayak) was entering the river from the public access just south of the St. Cloud Dam. The operator attempted to cross over swift moving water, and the current and rapids pulled the front of the kayak below the surface. The kayak filled with water and the operator was thrown into the river. He grabbed ahold of the kayak and was swept downstream. He yelled for help and went approximately three to four miles downstream before being assisted to shore by three other kayakers. He had no visible signs of injury but complained of being tired and sore. He was seen by ambulance staff and medically cleared but refused transport. The kayak is under 10 feet and is not required to be registered. Alcohol was not a factor. There was a life jacket in a compartment on the kayak, but it was not retrieved and operator was not wearing one. There was no damage to the kayak.
