Hanover Township near Loudonville in Ashland County, Ohio — The American Midwest (Great Lakes)
High Water Mark
July 10, 2006
The flash flood event of 2006 was the result of torrential rainfall from a cluster of strong afternoon thunderstorms that took aim at the Mohican State Forest. The heaviest rain fell between 3 PM and 5 PM, with storm total amounts ranging from 4.5 to 5.5 inches. This excessive amount of water roared out of the area hills, spilling into the valley below turning the creek into a rampaging torrent in minutes. The Clear Fork here saw water level rises of over 6 feet in a matter of hours, with water inundating all the way to State Route 3.
The National Weather Service will issue Flood Warning when flash flooding is occurring or is imminent in a specified area. If your locale is placed under a warning, you should move to safe ground immediately.

Beginning with the extreme flood of late June, northern Ohio and northwestern Pennsylvania entered an unusually active flash flood season that lasted through the month of July. Two consecutive days of heavy thunderstorms in late June brought the worst flooding many areas in northern Ohio had seen in nearly 40 years. When all was done six counties in Ohio (Cuyahoga, Erie, Huron, Lucas, Sandusky, and Stark) had been declared major disaster areas. Periods of torrential rains continued into July. In a little more than 5 weeks, at least 6 major flash flood events took place across the area. Three flood-related fatalities were reported during the month, and damage to homes and infrastructure totaled in the hundreds of millions.(Submitted on November 15, 2024, by Joel Seewald of Madison Heights, Michigan.)
