- Description:
-
- Abstract:
-
This spatial layer shows the boundary for the 8-digit hydrologic unit 11130302, which also is the boundary for the upper Washita River basin in southwestern Oklahoma.This spatial layer consists of geo-referenced digital data and associated attributes and was created from the preliminary version of the of Oklahoma Watershed Boundary Dataset, part of the National Watershed Boundary dataset.
- Purpose:
-
To provide a detailed drainage basin boundary for the upper Washita River basin and to clip other data sets included in the publication.
- Supplemental_Information:
-
This data set consists of geo-referenced digital data and associated attributes created in accordance with the FGDC Proposal, Version 1.0 - Federal Standards for Delineation of Hydrologic Unit Boundaries.

- Process_Description:
-
The 12-digit HUC was downloaded from <http://datagateway.nrcs.usda.gov>. The 12-digit sub-watershed boundarys in the 8-digit HUC 11130302 were deleted using the DISSOLVE command in ArcMap. The layer was projected, imported into the geodatabase and metadata written.
