DNR Minor Watersheds are the smallest administrative Minnesota watershed unit delineation existing at the 7th level defined in the Minnesota DNR watershed unit hierarchy. These modern DNR Minor Watersheds are derived from the DNR Catchment base-watershed dataset. Although the lineage of these watershed delineations dates back to the early 1970s, this data is an updated version of the DNR Minor 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 Minor Watershed delineations have been clipped to the Minnesota state boundary. For 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 DNR Level 07 Minor Watersheds are a legacy watershed delineation representing the 7th hydrologic unit level of the DNR watershed hierarchal system. These delineations serve as the standard-administrative hydrologic units for Minnesota. They are defined and referenced within Minnesota statutes (103G.005 Subd. 17a and 103B.305 Subd. 10) for official state watershed map production. 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.

ArcGIS File Geodatabase true -97.3 -89.4 49.4 43.4 Data have been tested for completeness and attribute coding correctness. The geometry of this data vary widely as to their currentness. The parent dataset, DNR Catchments, is the maintenance version of the statewide DNR Minor Watershed. The user of this data is encouraged to review the metadata entry for the DNR Watersheds Level 08 - All Catchments dataset for more detailed information concerning the currentness of this dataset. Statewide This DNR Minor Watershed dataset is topologically correct using ArcGIS 10.8. All polygons are closed and lines intersect where intended. This modern DNR Minor Watershed dataset was derived directly from the DNR Catchment layer. It was created by dissolving the DNR Catchments on the MINOR5 field so that DNR Catchment linework internal to the approximately 5,690 DNR Minor Watersheds are removed. The user of this data is encouraged to review the metadata entry for the DNR Watersheds Level 08 - All Catchments dataset for more detailed information. These data are published for November 2023. Source layer wshd_lev07py3: No quantitative studies of horizontal positional accuracy exist for the data. Although positional accuracy of watershed delineations can be arbitrary, accuracy of these data can be reasonably estimated based on the characteristics of all source materials and processing techniques to be 100 feet (30 meters) from correct position. Source layer wshd_lev07py3: No quantitative studies of vertical positional accuracy exist for the data.
