DNR Level 01 Watersheds are the largest administrative Minnesota watershed unit delineation existing at the 1st defined level in the Minnesota DNR watershed unit hierarchy.\n\nThese modern DNR Level 01 Watersheds are derived from the DNR Catchment base-watershed dataset. These Level 01 watersheds were formerly referred to as DNR Provinces (1-4), but we have discontinued this terminology. Although the lineage of the DNR Province watershed delineations dates back to the early 1970?s, this Level 01 data is an updated version of the DNR Province legacy watershed dataset that has been in existence in various published formats since 1979.\n\nThis new linework represents the general appearance of the legacy data. However, the geometry is considerably different. This has resulted from the DNR Watershed Delineation Projects methodology, which incorporates modern data sources to delineate watersheds that reflect the current hydrology and topography of the landscape. These modern DNR Level 01 Watershed delineations have been clipped to the Minnesota state boundary.\n\nFor a more detailed background on this data, follow this link to the History and Standards of Watershed Delineation in Minnesota and the DNR Watershed Delineation Project https://www.dnr.state.mn.us/watersheds/history_standards.html", "geometryType": "esriGeometryPolygon",
