Data downloads

The Statewide Repository of Dams spatial and tabular data can now be accessed using a web browser through the Wisconsin DNR GIS Open Data Portal. The open data portal is a free resource for locating, viewing, and downloading data developed and/or maintained by the Wisconsin DNR.

The dynamic map is updated daily and displays points representing the locations for all dams recorded in the dam safety database. Users can view dam locations spatially and associated attribute information in a table. Data may also be downloaded in several formats, including a shapefile, and users can filter the download based on the map extent.

• Statewide Repository of Dams - access to the GIS Open Data Portal
• Data dictionary – this document will help users decode the field names when viewing or downloading the data.
