The National Hydrography Dataset (NHD)
The National Hydrography Dataset (NHD) represents surface waters of the United States including, rivers, streams, lakes, and coastal features. The Watershed Boundary Dataset (WBD) is comprised of hierarchical polygons called hydrologic units that represent surface area over which water drains to a point. Both datasets are updated by stewards and are available by subsets of the United States.

The Latest Updates to the HydroAdd Tool
The HydroAdd tool is a web application built by USGS that allows collaborative addressing (or linear referencing) of diverse datasets to the NHD. HydroAdd also provides tools that allow users to migrate datasets that have been previously addressed to the NHD.

3D Hydrography Program Transition Timelines
The USGS is developing the 3D Hydrography Program (3DHP) as the surface water mapping component of the new 3D National Topography Model (3DNTM.) The 3DHP will provide critical data to support a broad range of national, regional, and local applications such as flood forecasting and response, agricultural planning, infrastructure design, stream ecology research a
