Sauk County Emergency Management officials are urging caution on Monday to residents threatened by an "unstable" levee system.
Residents from Indian Trails, located near Lake Delton, to the Columbia County line, along Levee Road, should stay out of their homes "until further notice."
Water levels in Sauk County are expected to rise another 1-2 inches over the next few days, officials said.
Wisconsin Department of Natural Resources engineers continue to monitor key levees but are unsure what might happen as the water continues to rise.
Sandbags are available at the Sauk County highway garage on Highway 136 near Pierce's Supermarket, officials said.
