Flooding also continued to be a problem in southeastern Missouri and southern Illinois, even though the Mississippi and Ohio rivers have already crested in those states.

Last week, the Corps intentionally breached a levee in Missouri as part of its effort to reduce the pressure on other levees, flooding 130,000 acres of agricultural land over the objection of state officials and some farmers.

"I'm very sad. I look at that and I don't have a home," Marilynn Nally said, pointing to her flooded family farm. "I feel like we're having to suffer for somebody else."

The latest flooding in the Mississippi and Ohio river valleys is largely the byproduct of torrential rains throughout the region. Over one two-week stretch, there was about 600% more precipitation than usual, forecasters said.

The weather appears to be working in the flood fighters' favor. Only minimal rain is expected over the coming days, with daytime temperatures forecast to be in the upper 80s and 90s through Thursday.
