WATERSHEDS HUC10 - 2009 --
Watershed Boundary Dataset (WBD) - Ten-Digit Watershed Boundaries for Indiana, 2009 (1:24,000)
Shows the most recent revision of watershed boundaries of 10-digit hydrologic accounting units. This data set, part of the Watershed Boundary Data set (WBD), is a complete digital hydrologic unit boundary layer to the Watershed (10-digit) 5th level for the NRCS business areas in and around the state of Indiana. Polygons are attributed with hydrologic unit codes for 4th level sub-basins, 5th level watersheds, name, size, downstream hydrologic unit, type of watershed, noncontributing areas and flow modification.
The Watershed and Subwatershed hydrologic unit boundaries provide a uniquely identified and uniform method of subdividing large drainage areas. The smaller sized 6th level sub-watersheds (up to 250,000 acres) are useful for numerous application programs supported by a variety of local, State, and Federal Agencies. This data set is intended to be used as a tool for water-resource management and planning activities, particularly for site-specific and localized studies requiring a level of detail provided by large-scale map information. Funding and support for the Watershed Boundary data set (WBD) were provided by the Natural Resources Conservation Service, the Environmental Protection Agency, and the United States Geological Survey
