Title:

Huc12 -- Watershed Boundary Dataset for 12-Digit Hydrologic Units

Geospatial_Data_Presentation_Form: vector digital data

Online_Linkage: <http://datagateway.nrcs.usda.gov/>

Description:

Abstract:

This spatial layer shows the hydrologic unit boundaries for the 12-digit sub-watersheds at a scale of 1:24,000 in the upper Washita River basin in southwestern Oklahoma. This data set consists of geo-referenced digital data and associated attributes and is a preliminary release of the 12-digit hydrologic unit Oklahoma Watershed Boundary Dataset, part of the National Watershed Boundary dataset.

Purpose:

To provide detailed watershed boundary data sets based on 1:24,000-scale topographic maps for the upper Washita River basin.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.

Supplemental_Information:

This spatial layer 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 [<http://www.ncgc.nrcs.usda.gov/products/datasets/watershed/> ].The hydrologic unit boundaries provide a uniquely identified and uniform method of subdividing large drainage areas.

Metadata at <http://www.ncgc.nrcs.usda.gov/products/datasets/watershed/metadata.html> provides information on the methodology used to delineate the hydrologic units and definitions for all attributes.

Process_Step:

Process_Description:

Data sets were copied from <http://datagateway.nrcs.usda.gov/> and joined. The 12-digit HUCs in the upper Washita River basin were selected and a shapefile was created. The data set was reprojected to Albers Conical Equal Area projection. The data set was then imported into the geodatabase and metadata written.
