Coastal Flooding

Coastal flooding affects all of Wisconsin's coastal communities to some degree, but is more prevalent when storms occur in low-lying areas during periods of high water levels. These resources help local officials and property owners better address coastal flooding.


Lake Level Viewer
This interactive map visualizes the extent of rising and falling water levels along the shores of the Great Lakes from six feet about average lake levels to six feet below in one foot increments. It includes the ability to explore the impact of rising water levels on vulnerable populations and businesses. Only areas with existing topographic and bathymetric lidar data are mapped. This leaves out some areas of the Wisconsin shore.
