Tiny Willow Creek became a wall of water, swept away a third of the town and killed 247 people; one out of every 6 Heppner residents died that day. It was the worst non-dam-related flash flood in U.S. history. (Heppner, Morrow County; 1903) (For text and pictures, see http://www.offbeatoregon.com/H1004c_HeppnerFlood.html)
