Frequently Asked Questions

USGS provides a listing of Frequently Asked Questions (FAQs). Please visit the USGS NHD FAQ page for this listing. Additional FAQs, frequently responded to by the PNWHF Partners are listed below.

  • Is there a whole stream identifier in the NHD?
    Currently the only whole stream identifiers in the NHD are the GNIS_ID and GNIS_NAME fields. The WA agencies (DFW and ECY) have agreed to develop a whole stream identifier based on LLID (lat/long identifier). The task is scheduled to begin this year. LLID'S developed by DFW will be used as identifiers.
  • How can my agency become an active NHD/WBD editor organization?
    Those whom have not previously been involved in NHD stewardship should contact their respective state data stewards, Bob Harmon (Oregon Water Resources Department, Robert.C.Harmon@state.or.us) and Anita Store (Washington Department of Ecology, asto461@ECY.WA.GOV.)
