What's New?

Flood Inundation Maps are now available for the Wisconsin River at Portage. These maps were created in partnership with the DNR. These interactive maps will help convey the impacts of flooding for local officials, property owners and motorists. Use these maps to answer questions like, "What roads may be impacted at 17 feet, and where are alternate safer routes?" and "If the river reaches 18 feet, how may my property be affected?".
