Wyoming Headwaters Project
Listed in NASA Earthdata CMR
The purpose of the Wyoming Headwaters Project is to refine existing USGS Hydrologic Unit Boundaries (HUBs) published in the mid 1970's on a national level (level 4 HUBs). 5th and 6th level hydrologic unit HUBs for the State will be defined at a 1:24,000-scale.
Description
Boundaries will be defined using the USGS Interagency Guideline on Delineation of Watershed and Subwatershed Hydrologic Unit Boundaries . 5th level HUBs (watersheds) will be between 40,000 and 250,000 acres and 6th level HUBs (sub-watersheds) will be between 10,000 and 40,000 acres.
The delineation will be conducted using ArcView GIS and Arc/Info GIS. In Phase 1 draft delineations at the 1:100,000-scale will be reviewed by HUB workgroups composed of interested parties working with the HUB technical committee (see contacts below). Coordination will also take place between neighboring states to ensure that watersheds are consistent over state boundaries.

In Phase II, final delineations will be made at the 1:24,000-scale. Both the workgroups and the HUB technical committee will review the delineations. Once the final changes are completed the Wyoming Natural Resources Data Clearinghouse will become the repository for the watershed data.
