Dane County Watershed Map

Our interactive map shows how water moves through watersheds in Dane County at an unprecedented level of detail. The map's purpose is to help plan land conservation practices to improve water quality and reduce downstream flooding. The detailed patterns of drainage and water retention shown on the map can also provide a new perspective to anyone who is interested in how water moves across the land surface.

The map includes a form for submitting map errors, which will be used to improve future versions.
