NHD & WBD Datasets

National Hydrography Dataset (NHD)

The NHD is a GIS Dataset used to portray surface water and represents the drainage network with features such as rivers, streams, canals, lakes, ponds, coastline, dams, and stream gages. The NHD is the surface water hydrography layer of The National Map.

For more information on the NHD, please visit the USGS NHD website and the NHD Feature Catalog.

Watershed Boundary Dataset (WBD)

IDWR and Natural Resource Conservation Service (NRCS), in cooperation with various state and local agencies, produced the statewide WBD for 5th and 6th field watersheds for the State of Idaho. Idaho received a Full Certification status for the WBD effort in Idaho on December 2, 2008. Thank you to all cooperators, data stewards and interested parties who helped in this endeavor!

For more information on the WBD, please visit the USGS WBD website or the NRCS Watershed website.

NHDPlus HR development for Region 17 (Pacific Northwest including the majority of Idaho) is done! The Beta NHDPlus HR for region 16 is also available!

You can access the NHDPlus HR data from these two locations:

To help with NHDPlus HR review/QC, please send an email to nhd@usgs.gov or submit your changes Using the USGS Markup application.

Downloads

The NHD & WBD are integrated into a common data model, and the new WBD boundaries are packaged with the NHD Subbasins as they are checked out and downloaded.

The NHD can be downloaded by Hydrologic Unit using the NHD Viewer, by Pre-Staged Subregion, by State Extract, or with a National Snapshot.

The WBD can be download a standalone dataset by areas of interest.
