WATERSHEDS HUC08 - 2009 --
Watershed Boundary Dataset (WBD) - 8-Digit Subbasin Watershed Boundaries for Indiana, 2009 (1:24,000)
Shows the most recent revision of watershed boundaries of 8-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 Subbasin (8-digit) 4th level for the entire United States. Polygons are Attributed with hydrologic unit codes for 1st (Region), 2nd (Sub-Region), 3rd (Basin), and 4th (Sub-Basin) Hydrologic Unit Level codes, names, Sub-Basin acres and square miles.
The Basin and Subbasin hydrologic unit boundaries provide a uniquely identified and uniform method of subdividing large drainage areas. The largest sized 4th level subbasins 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
