The spring Mississippi River flood of 1965 stands as the flood of record for nearly half of the river’s length (from about 100 miles north of Minneapolis, MN to Hannibal, MO). At the time, the crests of that April exceeded previous records by several feet at many river gage sites. To this day, those record crests still out distance the second highest crest by a foot or more at many of those same sites. This flood caused $225 million in damage to public and private properties, with $173 million of that occurring along the main stem of the Mississippi River. Emergency actions and evacuations, based on National Weather Service forecasts, prevented approximately $300 million in additional damage.
