 Flood Inundation Mapping service is now available for 3 river gauging locations on the Fox River in southeast Wisconsin...Waukesha, Burlington and New Munster.  On the NWS-Milwaukee/Sullivan web page, look for Rivers and Lakes.  Select the river gauge of choice and look for "Inundation Mapping".  See image below as an example.   This service allows the user to see what areas of land are covered by floodwaters at various river stages.  Move the mouse pointer over the listed stages on the left side of the image to see the changing coloring of flooded areas.

 This service was established for 5 locations on the Rock River in 2016.  More Flood Inundation Mapping projects are planned on other rivers in southern Wisconsin in the future.
