Water levels on the Mississippi and Illinois Rivers are rising, with some Missouri locations expected to reach or come within about a foot of 1993 flood levels. Army Corps of Engineers officials say flood duration is the main concern because prolonged high water saturates levees.
Missouri and Illinois have activated National Guard units, and Illinois has issued a disaster declaration covering 34 counties.
Prolonged river flooding threatens levees and extends barge disruptions on key grain routes, supporting higher barge freight and firmer Midwest grain basis until water recedes.
