Metadata created using Minnesota Geographic Metadata Guidelines


Metadata Summary

Originator Minnesota DNR - Division of Waters - Watershed Delineation Project
Abstract 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 1970?s, 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 document (PDF). This document may take a few moments to load for viewing.

Use Tips This dataset is useful for reporting purposes and displaying or conducting analysis on the DNR Level 07 Minor watersheds in Minnesota

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

As a whole, these watershed delineations do not represent DNR Total Upstream Watersheds because total upstream watersheds extend into adjacent states.

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

As a whole, these watershed delineations do not represent DNR Total Upstream Watersheds because total upstream watersheds extend into adjacent states.

Purpose 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.

Section 2 Data Quality Information Top of full metadata Top of page
Attribute Accuracy
Logical Consistency This DNR Minor Watershed dataset is topologically correct using ArcGIS 9.3. 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 5,680 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.
Completeness These data are published for September 2009.
Horizontal Positional Accuracy 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.
Vertical Positional Accuracy Source layer wshd_lev07py3: No quantitative studies of vertical positional accuracy exist for the data.
Lineage Attribute Lineage for source table WSHD_LEV07PY3: Source Data: wshd_lev07py3
Source Scale Denominator Source layer wshd_lev07py3: 24000
