As many as 100 homes could be pretentious by flood waters in Wisconsin as forecasters anticipate the total failure of a 120-year-old sand levee along the Wisconsin River.The levee, close to the city of Portage in Columbia County, began failing Sunday night, according to the National Weather Service's Milwaukee/Sullivan office.
"Once the levee totally fails ... it is unknown how far south the flood waters of the Wisconsin River will travel," the weather agency said Sunday night.
The levee is situated on the south side of the Wisconsin River, just south of Portage. The weather agency urged residents to move to higher ground. Roadways, including parts of Interstate 39, could close.
