There are still thousands of homes at risk.
The city of Davenport, IA braced for the next round of flooding by the Mississippi River Thursday.
More rain was headed for states already threatened by the rising river, which has left muddy mounds of debris for miles.
Already hundreds of residents have fled their homes as riverside counties declared states of emergency and low-lying roads were inundated.
The river is expected to crest Thursday or Friday at St. Paul. This year's 23.5-foot crest -- 9.5 feet above flood stage -- will be the third highest since
record-keeping began in 1867. Crests in 1965 and 1969 were higher.
A 400-mile stretch of the Mississippi River -- from Minneapolis, MN south to Muscatine, IA -- remained closed Thursday to boat and barge traffic and
residential areas along the river continued to be evacuated as the river continued to rise.
Nine counties in western Wisconsin have declared a state of emergency while 10 Iowa counties posted a disaster proclamation, according to local
emergency response officials.
Sandbagging efforts are continuing.
In La Crosse, WI water levels were measured at 16.2 feet Tuesday, and crested at 16.5 feet on Wednesday, one
foot short of the record 17.9 feet set in 1965. More than 200 people voluntarily left their homes in La Crosse.
Church-based volunteers throughout the region have assisted with local response efforts such as dike
construction, while Church World Service volunteer disaster consultants continue to monitor the situation.
Flooding in Fountain City, WI forced closure of a riverside highway. In that area, Amtrak was forced to shut a
rail route that takes passengers between Chicago and Minneapolis-St. Paul.
The Salvation Army and American Red Cross have opened several shelters for evacuees, said Lori Getter, spokesperson for the Wisconsin Division of
Local churches and other community organizations have been coordinating volunteers who can fill and pile sandbags.
On Abel-Essman Island -- located in the Mississippi River near Guttenberg, IA -- more than 200 of the 300 families living on the island abandoned their
homes. The river is expected to crest there Friday at about 21 feet -- six feet above flood stage.
Riverside towns in Illinois have built 1,000-foot sandbag levees.
Thousands of homes in Iowa, Wisconsin, Illinois, and Minnesota are at risk for flooding, said Jeff Stein, a spokesperson for American Rivers based in
Davenport. American Rivers is a nonprofit dedicated to protecting and restoring rivers nationwide.
Stein said that protecting people was a matter of "moving homes and businesses out of harm's way -- out of the flood plain where it's practical" rather
than repairing and rebuilding structures that are repeatedly flooded.
"There are going to be significantly fewer homes damaged this week" than there were in previous floods, he said, "but there are still thousands of homes
at risk. One of the things we've done to the Mississippi River and to other rivers is try to contain them. We've continued to develop areas around the
river both for agriculture and urban dwellings. We've created a situation where water makes its way to the river a lot faster."
Left in a more natural state, the river would be temporarily contained in the flood plain's wetlands, he said. "The water would be held in the soil for
awhile. It now takes less water to create bigger floods," he said.
The city of Davenport created river-walks and open-space parkland as a buffer to protect residential dwellings from floods, added Stein. The parkland is
now covered with water but so far no homes have been inundated.
Forecasters said the Mississippi was likely to stay high for several weeks, giving some levees their toughest tests since 1965.
