National Hydrography Infrastructure Working Group

The National Hydrography Infrastructure (NHI) Working Group is a forum for Federal agencies with direct involvement in the National Hydrography Infrastructure to provide input and collaborate on the direction, development, priorities, management, technologies, use, and resources of the National Hydrography Infrastructure.

The National Hydrography Infrastructure Working Group consists of the following member agencies:

  • Bureau of Land Management (BLM)
  • Bureau of Reclamation (BOR)
  • Environmental Protection Agency (EPA)
  • National Oceanic and Atmospheric Administration (NOAA) / National Weather Service (NWS)
  • National Park Service (NPS)
  • Natural Resources Conservation Service (NRCS)
  • U.S. Army Corps of Engineers (USACE)
  • U.S. Census Bureau
  • U.S. Fish and Wildlife Service (USFWS)
  • U.S. Forest Service (USFS)
  • U.S. Geological Survey (USGS)

Member agencies provide a primary and alternate representative, with the alternate acting for the primary as needed. The USGS is the lead agency for development and management of the National Hydrography Infrastructure and underlying hydrography datasets, including the NHD, WBD, and NHDPlus HR. The USGS chairs the NHI Working Group and also provides advisors to assist with programmatic and technical guidance on National Hydrography Infrastructure development and management.

The NHI Technical Subgroup falls under the NHI Working Group and provides information and recommendations related to NHI datasets and technologies. It consists of members of the NHI Working Group and others from the member agencies with an interest or stake in the details of data and tool development.
