PNW Hydrography Framework Redesign

The Pacific Northwest Hydrography Framework Partners are collaborating on several redesign initiatives:

Review and certification of the Watershed Boundary Dataset (WBD) for Oregon and Washington. This certification effort will result in a maintainable Watershed Boundary Dataset for Oregon/Washington. PNWHF stewardship of the WBD for Oregon/Washington will be coordinated with the USGS and NRCS.
Migration of the PNWHF Hydrography data to the National Hydrography Dataset (NHD) data model. The resulting dataset will be provided for download for both analytical and maintenance use from this website. PNWHF stewardship of the NHD for Oregon/Washington will be coordinated with the USGS national NHD repository.
Redesign of the PNWHF update/maintenance environment is needed to support both of these datasets. The resulting transaction management infrastructure will ensure integrity of both the NHD and WBD. All maintenance activities will be coordinated with the national USGS repositories for both datasets.
Application Development. The PNWHF is developing applications to support effective stewardship of the NHD and WBD. These applications are being developed in coordination with our national partners. Information on these applications and available downloads are provided below.

This page will provide access to pertinent status reports and documentation as these redesign projects proceed.
