Floodplain and Dam safety program interactive maps

The WDNR Dam Safety program´s mapping application allows the public access to the Wisconsin Dams database. USGS Topographic maps are displayed as a background and Air Photos become available as a background when you are zoomed into a scale of 1:24,000. Dam photos are available for many dams throughout the state.

Once you find the dam of interest, and you are zoomed in to at least 1:24,000, choose the identify button in the tool bar and click on the "yellow dot" which signifies the dam. Information on this dam is now shown in the left sidebar entitled "Identify Results". If you scroll down on this information, you will find a heading for "Representative Photo" which may have a link to the right entitled "more data". If there is a link and you click on this link, the photo of the dam will appear.

The WDNR Floodplain management program´s mapping application allows the public access to the Wisconsin Floodplain Analysis database. Floodplain Insurance Studies and Engineering Input Models are available for download through the ´Identify Results´ information of the flood study and bridge location lines and points. FEMA Floodplain Maps and Air Photos become available for viewing once you zoom in to a large scale (1:150,000). USGS Topographic maps may also be displayed as a background. Please Note: The FEMA maps displayed on this Web site are not the official maps and should not be used for zoning purposes.
