People who living along the Mississippi River in eastern Iowa and western Illinois are preparing for the water to crest Sunday, but officials expect water levels to remain high for several days.
Other rivers in the region are also swollen with rain water. In Rock Island County, Ill., a Rock River levee breached near Barstow on Saturday.
Officials evacuated about 60 residents of a mobile home park and quickly built an earthen dam to protect the town.
Rock Island County Board Chairman Phil Banaszek told the Quad-City Times residents were ordered to evacuate within 30 minutes because water was coming over the levee.
National Weather Service meteorologist Andy Ervin says both the Mississippi and Rock rivers are expected to remain high enough near Davenport to cause significant flooding through Thursday.
