Resource provided by UW-Madison Robinson Map Library. This data set is a polygon shapefile representing watersheds as delineated by the Wisconsin DNR. The data are compiled from 1:24,000-scale topographic maps. DNR watershed delineations generally indicate areas that drain into a common river system or lake, but may also be based on DNR basin management criteria. The custodian of this data set is the DNR Bureau of Watershed Management (WT).
