ST. LOUIS >> Residents in parts of southwestern Iowa were forced out of their homes today as a torrent of Missouri River water flowed over and through levees.

Heavy rainfall and snowmelt forced river levels across several Midwestern states to dangerous levels. At least two deaths were blamed on flooding, and two other men have been missing for days. While river levels today were starting to level off in Nebraska, other residents in Iowa, Kansas and Missouri were bracing for worse flooding to come.

The Missouri River reached 30.2 feet today in Fremont County, Iowa, in the state’s far southwestern corner, 2 feet above the record set in 2011. People in the towns of Bartlett and Thurman were being evacuated as levees were breached and overtopped.

County Emergency Management Director Mike Crecelius said it wasn’t just the amount of the water, it was the swiftness of the current that created a danger.

“This wasn’t a gradual rise,” Crecelius said. “It’s flowing fast and it’s open country — there’s nothing there to slow it down.”

Thurman has about 200 residents. About 50 people live in Bartlett.

Lucinda Parker of Iowa Homeland Security & Emergency Management said nearly 2,000 people have been evacuated at eight Iowa locations since flooding began late last week. Most were staying with friends or family. Seven shelters set up for flood victims held just a couple dozen people Saturday night.

Hundreds of people remained out of their homes in Nebraska, but rivers there were starting to recede. The National Weather Service said the Elkhorn River remained at major flood stage but was dropping. It was expected to dip back below flood stage by Tuesday. U.S. 30 reopened near Arlington on Saturday.

The flooding is blamed on at least two deaths. Aleido Rojas Galan, 52, of Norfolk, Nebraska, was swept away in floodwaters Friday night in southwestern Iowa, when the vehicle he was in went around a barricade. Two others in the vehicle survived — one by clining to a tree. On Thursday, James Wilke, 50, of Columbus, Nebraska, died when a bridge collapsed as he used a tractor to try and reach stranded motorists.

Two men remain missing. A Norfolk man was seen on top of his flooded car late Thursday before being swept away. Water also swept away a man after a dam collapse.

In St. Joseph, Missouri, home to 76,000 people, volunteers were helping to fill sandbags to help secure a levee protecting an industrial area. Calls were out for even more volunteers in hopes of filling 150,000 sandbags by Tuesday, when the Missouri River is expected to climb to 27 feet — 10 feet above technical flood stage.

The rising Mississippi River also was creating concern. The Mississippi was already at major flood level along the Iowa-Illinois border, closing roads and highways and swamping thousands of acres of farmland. Moderate Mississippi River flooding was expected at several Missouri cities, including St. Louis.

Flooding has also been reported in Minnesota, South Dakota and Wisconsin.
