National Hydrography Dataset | U.S. Geological Survey
Explore the U.S. National Hydrography Dataset for detailed maps and data on rivers, lakes, and water networks across the country. Data in English.
Access detailed U.S. water network data
The National Hydrography Dataset (NHD) from the U.S. Geological Survey provides comprehensive data on the nation's surface water features. You can explore detailed maps and datasets covering rivers, streams, lakes, ponds, and more, making it a valuable resource for anyone interested in U.S. water networks and geography.
Whether you're a researcher, environmental professional, or simply curious about your local waterways, the NHD offers tools and information to help you understand how water moves across the landscape. Although the NHD is no longer actively maintained, its data remains accessible, and the newest updates are available through the 3D Hydrography Program (3DHP).
This site is designed for easy access to hydrography data and related resources. You can find links to maps, scientific publications, and additional USGS programs, making it a helpful starting point for exploring water resources and environmental science in the United States.
