Section 1: Overview
Originator:Minnesota Department of Natural Resources (MNDNR)
Title:
MNDNR Watershed Suite
Purpose:
These watershed delineations are suitable for regional and statewide GIS analysis, database tiling, reference, business reporting, small scale mapping and other business needs associated with hydrologic systems.
These polygons provide a means for organizing land use and related data in a manner which is useful for hydrologic studies and watershed based decision-making.
Flow Network Lines and Pour Points were created to aid in lake watershed management, from fish and game habitat management to calculating storm water run-off and water quality.
Time Period of Content Date:

Currentness Reference:
Time Period of Content Date indicates when dataset was last updated.
The geometry of this data vary widely as to their currentness. The parent dataset, MNDNR Catchments, is the maintenance version of the MNDNR Major Watershed dataset. The user of this data is encouraged to review the metadata entry for the MNDNR Watersheds Level 08 - All Catchments dataset for more detailed information concerning the currentness of this dataset.

ACKNOWLEDGMENTS:
- As defined in the MNDNR License Agreement, users of this data must credit the Originator on published maps and analysis.
- The user shall include the Minnesota MNDNR source data Title (name).

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 any MNDNR legacy dataset. This modern MNDNR Level 02 dataset was derived directly from the MNDNR Catchment layer. The user of this data is encouraged to review the metadata entry for the MNDNR Watersheds Level 08 - All Catchments dataset for more detailed information.
- The MNDNR Level 02 Watershed dataset is specific to the state of Minnesota and is not part of the NRCS Watershed Boundary Dataset (WBD).

Logical Consistency:
Catchment data were originally digitized heads-up in ArcView 3.x as polyline shapefiles. These data were then incorporated into ArcINFO 7.0.3 for data scrubbing and attribute assembly. An initial ARC CLEAN was run on the data with a fuzzy tolerance of 0.1. Lines were intersected and then built into polygons. In 2008, the data was migrated into ArcGIS 9.3 where all DNR Catchment polygons were assembled into a statewide-seamless watershed dataset using ArcGIS 9.3 ArcGIS File Geodatabase topology rules and editing tools. These DNR Catchment data are topologically correct, all polygons are closed and lines intersect where intended. Data have been tested for completeness and attribute coding correctness.
Completeness:
Complete over the area of the State of Minnesota
Horizontal Positional Accuracy:
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:
No quantitative studies of vertical positional accuracy exist for the data.
