Washington Shared Hydrography Framework Project


The Washington Shared Hydrography Framework Project is the cooperative effort to define, implement, and maintain a single high resolution hydrography network for Washington State.

The ultimate goal of the project is to establish a common "core" set of spatial and tabular hydrography information to which all organizations can attach their business specific requirements. The primary benefits of the project include the ability to effectively store, access, analyze, model, and exchange hydrographic data between interested parties. These benefits are being realized by the implementation of a single surface water information system for the region which provides a common reference for all organizations sharing hydrography data.

Participating Agencies

NHD Adopted as the State Standard for Hydrography Data

The goal of the project is to create unified lakes, rivers, and streams digital GIS layers, which are essential for a coordinated approach to ecosystem management and accountability.  Previously, three different sets of regulatory information meant that decisions on environmental permits were often in conflict, frustrating businesses, the public and local governments.

Two pilot projects conducted by the state agencies listed above, along with the U.S. Bureau of Land Management and the U.S. Forest Service led to the recommendation of the National Hydrography Dataset (NHD) as the state standard for surface water hydrography.  In January 2011, the Geospatial Information Technology (GIT) Committee of the Information Services Board (ISB) accepted that recommendation, which was then presented to and approved by the ISB.

With the NHD accepted as the official surface water database standard for Washington State, the participating state agencies joined our federal partners in the Pacific Northwest Hydrography Framework (PNWHF), the BLM and the USFS, as local stewards of the NHD.  The U.S. Geological Survey serves as the national steward of the database. Additional information on how the NHD is managed by the PNWHF can be accessed at http://www.pnwhf.org.
