Venango County Coroner Tyler Best has ruled 56-year-old William Root's death an accident.
Root, of Aston, was pulled from the river after a fellow kayaker called 911 to report the incident about 3:40 p.m. Sunday. Root died a short time later at UPMC Northwest hospital in Seneca.
Root was kayaking in Rockland Township near Kennerdell, about 70 miles north of Pittsburgh.
Best says the autopsy was performed Monday. Windy conditions contributed to the rough water that caused Root to fall into the water.
