Heavy rains of 2 to 4 inches caused flash flooding on a creek feeding into the Grand River. At a ranch southwest of Bullhead, a bunkhouse wall moved off the foundation by a wall of water coming down the creek. All of the contents in the bunkhouse were destroyed. A machine shop was washed away along with several pieces of equipment and many tools. Some tools and equipment were found more than a mile down the creek. A pump-house and grain bin was also destroyed. A pickup was washed down the creek and a propane tank near a house was rolled over. A colt was picked up by the water but managed to escape. The powerful flow of water took out several dead trees and washed them down stream. Finally, a road and a culvert were washed out by the flash flood.
