RedactedNarrative: Operator was in the stern operating the boat while he and passenger were fishing.  The canoe struck a rock causing the back of the canoe to come out of the water and the canoe to spin on the rock.  When the motor hit the water again the propulsion shot the canoe at an angle causing it to capsize.  Both operator and passenger were wearing life preservers.  Passenger was able to swim to shore and go for help. Operator held on to the side of the canoe and drifted downstream until I was able to get to him with my boat.  Operator was tended to by paramedics and placed into the ambulance.
