In the summer of 1993, heavy rains in the Midwest caused the Mississippi, the Missouri, and several other rivers to overflow their banks. The vast upper Mississippi floodplain, which drains more than a third of the nation's runoff, was completely inundated. The resulting flood covered millions of acres of farmlands and destroyed entire towns. The unusual weather pattern was the major cause of the flood. Other factors may have contributed to the devastation, including the decision in the 1930s to have the Army Corps of Engineers re-route the Mississippi River and build a series of dams and levees to hold the river to its new course. Through interviews with civil engineers, flood survivors, floodplain management officials, and others, NOVA examines the Great Flood of 1993, probes the issues generated by the flooding, and explores what might be done to decrease future flood losses. |
