Water Resources
Water information is fundamental to national and local economic well-being, protection of life and property, and effective management of the Nation’s water resources. The USGS works with partners to monitor, assess, conduct targeted research, and deliver information on a wide range of water resources and conditions including streamflow, groundwater, water quality, and water use and availability.
USGS Water Data for the Nation
Surface-water, groundwater, water-quality, and water-use data collected at approximately 1.9 million sites across all 50 states.
