Viewing Floodplain Analysis and Maps
Wisconsin DNR floodplain mapping application
The DNR Floodplain Management Program's mapping application allows the public access to the Wisconsin Floodplain Analysis database and FEMA's National Flood Hazard Layer. Floodplain Insurance Studies and Engineering Input Models are available for download through the 'Identify Results' information of the flood study location polygons, lines and points.
Once you find an area of interest, use the "Identify Point" tool to click on a floodplain, dam, or other feature to display additional information in the left sidebar, including links to associated photos, documents, and input models if available.
Please Note: FEMA's floodplain layer displayed on this website is not the official map and should not be used for regulatory purposes, such as floodplain zoning. This layer is strictly for informational purposes. To view and download the official, effective flood insurance rate maps visit FEMA's Map Service Center.
