1. State of Alaska Watershed and Stream Hydrography Enhanced Datasets (AWSHED) Project
2. Project Background and Details Prior to the completion of this project, the State of Alaska had defined watersheds to the 4th Level sub-basin level. The Alaska Geospatial Data Committee (AGDC) and the Alaska state government expressed a need to further refine this scale to a watershed (5th level) and sub-watershed (6th level) system. These Watersheds and sub-watersheds would be Delineated and certified into the national Watershed Boundary Dataset (WBD), thus leading to Increased capabilities for watershed modeling and sharing of aquatic resources information in Alaska.
3. The following is a visual illustration of the process of watershed and sub-watershed delineation that took place.
21. At time of completion over 1000 fully named and numbered watersheds were created and almost 15,000 sub-watersheds. Futher documentation on this project can be found at http://agdc.usgs.gov/hydro/
