Areas near major tributaries have been inundated, particularly around St. Louis, where the Illinois, Meramec and Missouri rivers meet the Mississippi. Nearly 450 gauges have hit flood stage, according to the U.S. Geological Survey, and in some places water has overrun levees. Thousands of people have been displaced and at least 20 have died.

Flooding has created transportation havoc, disrupting rail lines, ferry service, states roads and even major interstates. A pipeline that carries oil from Oklahoma to Illinois was shut down. Prisoners had to be moved out of a maximum-security prison in Chester, Ill.

Water levels are receding in parts of Illinois and Missouri, but forecasters expect problems in Memphis, Vicksburg, Miss., and Baton Rouge, La., in the coming days as the huge volume of water makes its way toward the Gulf of Mexico.

The deluge proved too much for this scenic Mississippi tributary, which functions as the area’s catch basin. Record floods were recorded at several places and homes and businesses were inundated. At Arnold, Mo., the water crested at more than 47 feet, an alltime high by 2 feet.

The Missouri river crested more than 10 feet above flood stage at St. Charles, Mo. Flooding is occurring or expected to occur on the Illinois, Ohio and Red rivers.

The dam at Toad Suck, Ark., recorded its second-highest water level in history on Thursday. Several parks and roads were closed in Little Rock in anticipation of flooding that was expected to crest on Friday.
