Track: Water Resources
Authors: Karen Hanson
The Watershed Boundary Dataset (WBD), a companion dataset to the National Hydrography Dataset (NHD), is a nationally consistent, seamless, and hierarchical hydrologic unit boundary dataset based on topographic and hydrologic features across the U.S.
Since completion in 2009 WBD stewardship activities have been ongoing, and include data enhancements, international cooperative efforts, coastal delineations, and integration with other national programs in support of scientific investigations.
