Title: DNR Watersheds - DNR Level 04 - HUC 08 - Majors

Abstract: Back to main DNR Watershed Suite metadata page

These data consists of 80 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 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 1970s, 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.


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

Purpose: DNR Level 04 Major Watersheds are a legacy watershed delineation dataset representing the 4th 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.

Time Period of Content Date: 1998 - Present

Currentness Reference: 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 DNR Major Watershed dataset. 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.

USE CONSTRAINT COMMENTS:

- See Cartographic Lineage, Logical Consistency, Positional Accuracy, and Currentness Reference for further discussion of data capture.

- This data is not the same as the Minnesota DNR Major Watershed legacy data. This modern DNR Major dataset was derived directly from the DNR Catchment layer. 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.

- The DNR Major Watershed dataset is specific to the state of Minnesota and is not part of the USGS Watershed Boundary Dataset (WBD).

Section 2: Data Quality

Attribute Accuracy:

Logical Consistency: This DNR Major Watershed dataset is topologically correct using ArcGIS 10.8. All polygons are closed and lines intersect where intended.


This modern DNR Major Watershed dataset was derived directly from the DNR Catchment layer. It was created by dissolving the DNR Catchments on the MAJOR field so that DNR Catchment linework internal to the 80 DNR Major 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.

Completeness: These data are published for November 2023.

Horizontal Positional Accuracy: Source layer wshd_lev04py3: 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.

Vertical Positional Accuracy: Source layer wshd_lev04py3: No quantitative studies of vertical positional accuracy exist for the data.

Lineage: Attribute Lineage for source table WSHD_LEV04PY3: Source Data: wshd_lev04py3

Section 5: Attributes

Overview: Data Elements for Attribute Table DNR_WATERSHEDS_DNR_LEVEL_04_HUC_08_MAJORS:

MAJOR: Minnesota DNR Major Watershed ID numbers.
1-5, 7-44, 46-63, 65-74, 76-84.

MAJOR Note:
(1998) Minnesota DNR Major Watershed 6, 45, and 64 do not exist. These legacy delineations were removed by DNR Division of Waters from the official DNR Major Watershed Map during updates prior to the digital, GIS-based DNR Watershed Delineation Project updates (1998 – 2011).

(2023) Major Watersheds 75 (Rainy River – Manitou) and 79 (Rainy River - Baudette) were combined into one Major Watershed called the Lower Rainy River retaining number 79. The change to the DNR’s data aligns with the USGS Watershed Boundary Dataset (WBD) - Lower Rainy River (09030008).

MAJOR_NAME: Current names of DNR Major Watersheds were created in 2002 and published in 2009.

Watershed delineation updates occur within the DNR Catchment dataset.

Since all DNR watersheds are derived from the DNR Catchment dataset, the items will always equal 'DNR Catchment Dataset'.
