The Flood of 1993 was the costliest, most devastating flood in U.S. history according to the U.S. Geological Survey.
Floodwaters covered as many as 23 million acres of agricultural and urban lands in the Upper Midwest for weeks. The unusual duration and magnitude of this event was triggered by a wet-weather pattern that had persisted since early in
the year, followed by a series of intense rainstorms in late June and July. Iowa found itself in the center of the catastrophic flooding that resulted

In the image to the right (see U.S.G.S. reference above) floodwaters from the Des Moines River
(background) turn Interstate 80 into a causeway connecting remaining segments of dry land in this July 12, 1993 event.
