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 While these legacy products are no longer updated and maintained, they are provided here as both downloadable products and as services for reference purposes.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.
