Statewide lake watershed delineations for all lakes that have a surface area of 100 acres in size or larger. Data includes major watershed identifiers and USGS hydrologic unit codes (HUC). The data also includes pour point of each unit. This data was created from hydrologically corrected digital elevation models (ANUDEM) in concert with on-screen delineation in ArcView.

Statewide lake watershed delineations for all lakes that have a surface area of 100 acres in size or larger. Data includes major watershed identifiers and USGS hydrologic unit codes (HUC). The data also includes flow network accumulation lines for each unit, presenting the theoretical volume and placement of surface water run-off. This data was created from hydrologically corrected digital elevation models (ANUDEM) in concert with on-screen delineation in ArcView.

These data consists of over 10,000 watershed polygon delineations in one seamless dataset of drainage areas called Minnesota Department of Natural Resources (DNR) Catchments. The DNR Catchment dataset extends into adjacent states where water flows into Minnesota and or where the DNR Catchment extends across the state boundary.
Minnesota DNR Catchments are the smallest delineated and digitized drainage area mapped by the Minnesota DNR Watershed Delineation Project. The overall goal of this mapping effort is to produce the best watershed delineations available that reflect the current hydrology of the landscape as interpreted from as many data sources necessary to derive acceptable catchment delineations. Minnesota DNR Catchments are delineated from the perspective of hydrologists who refrained from allowing cartography to drive the delineation linework. This was accomplished by excluding political boundaries and cartographic esthetics during the delineation procedure, focusing instead, on landscape hydrology. Minnesota DNR Catchments contain all of the land area (including all water features), upstream from, or between DNR Pour Points. Therefore, Minnesota DNR Catchments are not scale dependant. There is no size limit as to how large or small the delineation may be, an individual DNR Catchment in the dataset may represent the drainage area of a 1-acre prairie wetland or a 100-acre recreational lake.

These data consists of approximately 5,680 watershed delineations in one seamless dataset of drainage areas called Minnesota Department of Natural Resources (DNR) Minor Watersheds. 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 paper DNR Watershed Project: History, Methodology, Terminology, Attributes 2009(DNR_Watershed_Project_History_Methodology_Terminology_Attributes_2009.pdf - location unknown) document (PDF).

These data consists of 81 watershed delineations in one seamless dataset of drainage areas called Minnesota Department of Natural Resources (DNR) Major Watersheds. DNR Major Watersheds are the largest administrative Minnesota watershed unit delineation existing at the 4th defined level in the Minnesota DNR watershed unit hierarchy.

These data consists of watershed delineations in one seamless dataset of drainage areas called Minnesota Department of Natural Resources (DNR) Level 02 Watersheds. DNR Level 02 Watersheds are the largest administrative Minnesota watershed unit delineation existing at the 2nd defined level in the Minnesota DNR watershed unit hierarchy. These modern DNR Level 02 Watersheds are derived from the DNR Catchment base-watershed dataset and have been clipped to the Minnesota state boundary. Unlike DNR Levels 01, 04 (Major), and 07 (Minor) Watersheds, DNR Level 02 watersheds have no corresponding legacy dataset.

These data consist of 4 watershed delineations in one seamless dataset of drainage areas called Minnesota Department of Natural Resources (DNR) Level 01 Watersheds. 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.
These 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.
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 Level 01 Watershed delineations have been clipped to the Minnesota state boundary.
