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
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.

Combining remote sensing and water-balance evapotranspiration estimates for the conterminous United States
Evapotranspiration (ET) is a key component of the hydrologic cycle, accounting for ~70% of precipitation in the conterminous U.S. (CONUS), but it has been a challenge to predict accurately across different spatio-temporal scales. The increasing availability of remotely sensed data has led to significant advances in the frequency and spatial...

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.
Sediment fingerprinting has been used successfully to identify land uses that are the major sources of sediment. This study will apply these techniques in a predominantly rural, volcanic landscape.
