Water Resources

狠狠噜天天噜日日噜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.

Concentrations of suspended sediment decreasing in many US streams and rivers

reports that landscape management actions across the U.S. aimed at reducing concentrations of suspended sediment in streams and rivers may be seeing some success. Between 1992 and 2012, concentrations of suspended sediment decreased at almost 60% of the 132 U.S. stream sites considered. Sediment...

Atrazine concentrations have decreased in streams and rivers across the United States

From 2002 to 2012, concentrations of atrazine decreased in more than one-half of 60 U.S. streams and rivers studied and increased in only about one-third of these streams, according to a by the U.S. Geological Survey National Water Quality Program. The streams and rivers are in a range of land-use settings.
