Description:
Abstract:
This data set contains hydrologic unit boundaries at the Watershed (5th-Code) level. The data set was developed by delineating the boundary lines on 1:100,000 scale base maps or overlays and digitizing the delineated lines. 5th-code number assignment is subject to change in 4th-code units that span state boundaries as final 5th-code boundaries are developed for North Dakota, South Dakota, and Wyoming. The coverage version of this data set also has a region subclass named "fourcode" that contains the 4th-code sub-basins. For 4th-code sub-basins in shapefile format, see <http://nris.state.mt.us/nsdi/nris/subbasin.html>.
Purpose:
The watershed hydrologic unit boundary provides a uniquely identified and uniform method of subdividing large drainage areas. These smaller sized hydrologic units (approximately 40,000 to 250,000 acres) are useful in many programs supported by the Natural Resources Conservation Service and others.

The U.S. Department of Agriculture, Natural Resources Conservation Service, Montana State Office, should be acknowledged as the data source in products derived from these data.

This data set is to be used as a primary reference source. This is public information and may be interpreted by organizations, agencies, units of government, or other based on needs, however, they are responsible for the appropriate application. Federal, State, or local regulatory bodies are not to reassign to the Natural Resources Conservation Service any authority for the decisions they make. Photographic or digital enlargement of this map to scales greater than 1:100,000 can cause misrepresentation of the data. If enlarged, the maps will not include the fine detail that would be appropriate for mapping at the large scale. Digital data files are periodically updated. Files are dated, and users are responsible for obtaining the latest revision of the data.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Polygon identifiers are manually checked with the original base map using the attribute file. Verification on polygon identification continuity of each side of a neatline is done visually on the computer screen as adjacent quad representations are assembled into larger area data layers.
Logical_Consistency_Report:
Certain node/geometry and topology polygon/chain relationships are collected or generated to satisfy topological requirements including: chains must begin and end at nodes and there are no duplicate lines or sliver polygons. Data beyond the state boundary is not included and is clipped at the boundary. All internal polygons are texted for closure and are checked using hard copy check plots. All data are checked for common boundary lines (i.e. adjacent polygons with the same label).
Completeness_Report:
The data is complete for the state of Montana. Meets national USDA NRCS specifications for the delineation of 5th-Code watersheds. Further delineation at the Sub-watershed (6th-code) level will be completed on an as-needed basis to meet USDA NRCS mission objectives. Sub-watersheds (10,000 to 40,000 acres) will be delineated using a base map scale of 1:24,000. The Subwatershed coverage will meet specifications as set forth in Natural Resources Conservation Service National Instruction 170-304 (revised).
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The approximate horizontal accuracy of the base maps is 51 meters, assuming they meet National Map Accuracy Standards. The accuracy of the watershed maps is generally based on contour information available for the base maps. Such data may be supplemented with site visits to locate ridge lines for hydrologic unit boundaries in flat terrain areas or to identify changes in drainage patterns due to human or geologic activity. The difference in positional accuracy between the hydrologic unit boundaries and their digitized map locations is unknown.

Hydrologic unit boundaries generally were digitized to be within 0.01 inches of their locations on the digitizing source (25 meters on the ground). The digital map elements are edge matched against the data for the adjacent quadrangle. Edge match locations generally do not deviate from centerline to centerline by more than 0.01 inches.
