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 wateruse and availability.

USGS Water Data for the Nation

USGS Water Data for the Nation

The USGS National Water Information System (NWIS) contains surface-water, groundwater, water-quality, and water-use data collected at approximately 1.5 million sites across all 50 states.

Large River Science

Expertise in large river research provides science information to inform decisions on river management and restoration in the Midwest Region. Connectivity is a fundamental concept in river ecology and refers to opportunities for water to flow along and through riverine ecosystems. It is considered one of the primary drivers of river productivity, biological diversity and ecosystem health.
