The Black River is receding at Poplar Bluff, Mo., and some 1,000 evacuees are now allowed to go home.

Officials in the southeast Missouri community of 17,000 residents on Thursday lifted a mandatory evacuation order for a large section of town, where river water has been pouring over the top of the levee.

Residents in the impacted area can return home whenever they choose.

Many will find a mess left behind by the murky water. Officials don't yet know how many homes were damaged in Poplar Bluff and in a rural area of Butler County also protected by the levee.

The National Weather Service said Thursday that after a crest of 21.4 feet on Tuesday, the Black River at Poplar Bluff was down to 19.1 feet.

The Army Corps of Engineers says it will wait until this weekend to decide whether to intentionally break a southeastern Missouri levee along the Mississippi River.

The Corps has said it may have to blow holes in the Birds Point levee to ease rising waters near the Illinois town of Cairo which sits near the confluence of the Ohio and Mississippi rivers.

Missouri has sued (see 12:58 update) to block the effort because it would swamp farmland. A hearing is scheduled for Thursday.

But Corps spokesman Bob Anderson tells The Associated Press that even if a judge gives the go-ahead, the agency will wait until it gets a better forecast of the river crests to see if the breach is necessary. That decision isn't likely to come until at least this weekend.

Illinois Lt. Gov. Sheila Simon is defending the idea of intentionally breaching a Missouri levee to reduce flooding in Cairo.

Missouri officials object to the plan, saying it would endanger 130,000 acres of prime farmland.

But Simon told The Associated Press on Tuesday that farmers will be compensated for their losses and will be able to use the land next year. On the other hand, flooding could devastate the poor town of Cairo.

She noted an Illinois levee was intentionally breached during 1993 flooding.

Simon also says the Army Corps of Engineers would not break the Birds Point levee until water had already topped the levee.

The Corps of Engineers says it will put off a decision until at least Wednesday.

U.S. Senator Claire McCaskill says she has concerns about the intentional breaching of the levee at Birds Point (via a press release):

“While emergency responders and volunteers work to save lives and protect property as best they can, the Army Corps of Engineers are working to find a solution to alleviate the stress from our levees.  I have grave concerns about the plan to intentionally breach Bird’s Point Levee that is being considered. In the effort to prevent more damage, we may do additional significant harm to the agricultural economy of the region that will last well after the flood waters recede.”

The release says McCaskill has already communicated her concerns with the Army Corps of Engineers' leadership.
