Access 3DHP Data Products

By 3D Hydrography Program

3D Hydrography Program data and legacy National Hydrography data products are available for download and as web-based map and data services. 

3D Hydrography Program Data Products

3DHP products are available in two forms – web services and a downloadable product.  New Elevation-Derived Hydrography (EDH) data and attributes will be added to the services quarterly, and the downloadable product will be updated early each Fiscal Year.  The annual downloadable products will remain available for reference with Digital Object Identifiers.

Legacy National Hydrography Products 

In 2024, the USGS shifted from maintaining the National Hydrography Dataset (NHD), the Watershed Boundary Dataset (WBD), and the NHDPlus High-Resolution to production of 3D Hydrography Program products.  While these legacy products are no longer updated and maintained, they are provided here as both downloadable products and as services for reference purposes.  More information about the legacy datasets is available on the About National Hydrography Products webpage.
