These modern DNR Major Watersheds are derived from the DNR Catchment base-watershed dataset. Although the lineage of these watershed delineations dates back to the early 1970?s, this data is an updated version of the DNR Major legacy watershed dataset that has been in existence in various published formats since 1979.

This 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 Major Watershed delineations have been clipped to the Minnesota state boundary.

DNR Level 04 Majors are equivalent to a NRCS Watershed Boundary Dataset (WBD) 4th level ? HUC 8 (Sub-basin) watershed

This data may be used for regional and statewide GIS analysis, database tiling, reference, business reporting and small scale mapping within Minnesota.

This data may be used for regional and statewide GIS analysis, database tiling, reference, business reporting and small scale mapping within Minnesota.

To standardize and adopt an official set of watershed boundaries for regional and statewide GIS analysis, database tiling, reference, business reporting, small scale mapping reporting, and other business needs associated with hydrologic systems.

To provide a means for organizing land use and related data in a manner which is useful for hydrologic studies and watershed based decision-making.
