What's New?

Flood Inundation Maps are now available for 3 locations along the Fox River in southeast Wisconsin in Waukesha, Racine, and Kenosha counties. These interactive maps will help convey the impacts of flooding for local officials and property owners. Use it to answer questions like, "If the river reaches 8 feet, how may my property be affected?". This service is also available for 5 locations along the Rock River, including Watertown, Jefferson, Fort Atkinson, Lake Koshkonong, and Afton.

In addition, river forecasts will now be available when the river is expected to approach or exceed the river bank for the Fox River in Waukesha. This means river flood watches and warnings will also be issued when the river is expected to go above flood stage. This service is already available at downstream locations of the Fox River including Burlington and New Munster.
