NHDPlus HR Beta Completed for CONUS!

Release Date:

NHDPlus High Resolution (NHDPlus HR) Beta datasets are now available for CONUS, Hawaii, U.S. Territories, and parts of Alaska.

We are excited to announce that the NHDPlus High Resolution (NHDPlus HR) has been completed and is publicly available for all of CONUS! It is also available for Hawaii, the U.S. Territories, and parts of Alaska. 

We would like to thank everyone who contributed to this exciting advancement, from the staff at the National Geospatial Technical Operations Center, to the Stewards who have worked to improve the data for decades, to the many users who participated in the Beta QC/Review process.

Our next steps are to continue to work on updates to NHD and WBD in Alaska in support of NHDPlus HR Beta production in the state. We also will begin to update some of the CONUS NHDPlus HR Beta datasets to correct errors and utilize improvements made to the NHD and WBD since the Beta data was produced. We are still working to determine those areas, but will let you know which they are as soon as we have them chosen.

Again, thank you!

The map below provides an overview of NHDPlus HR availability. This status map is updated frequently on the NHDPlus HR webpage.

  • Red outline - These areas are currently closed to NHD and WBD editing. Please contact the National NHD Point of Contact (Joel Skalet, nhd@usgs.gov) or National WBD Point of Contact (Lily Niknami, lniknami@usgs.gov) for more information on the status of NHD and WBD editing in these areas.
  • Blue areas - NHDPlus HR Beta is currently available and Beta QC is either in process or completed for these areas. Please see the NHDPlus HR Beta QC section of the NHDPlus HR webpage.
  • Yellow areas - The NHDPlus HR Beta is in production and the USGS is currently seeking volunteers for the upcoming Beta QC for these areas. Please see the NHDPlus HR Beta QC section of the NHDPlus HR webpage for more information. Please contact the National NHD Point of Contact (Joel Skalet, nhd@usgs.gov) or National WBD Point of Contact (Lily Niknami, lniknami@usgs.gov) for more information on the status of NHD and WBD editing in these areas.
  • Gray areas - NHDPlus HR Beta will be produced at a later date. These areas are currently open for NHD and WBD editing.
  • Green areas - The NHDPlus HR Beta was produced using contributing areas in Mexico to improve the NHDPlus HR Beta along the Rio Grande River. Minimal hydrography was included in the Beta build but will be improved when the areas are refreshed. The NHDPlus HR Beta production data with minimal hydrography content is available upon request.
