A broad survey of regional patterns in stream flow nationwide. Maps and graphs summarizing streamflow conditions for water-year 2010 (October 1, 2009 to September 30, 2010) in the context of the 81-year period 1930-2010.

Streamflow statistics and basin characteristics for most streams in specific US states using the Streamstats program. Data for areas can be selected from interactive maps and by an automated process. Includes a tutorial.
About 355,000 million gallons per day of water was withdrawn for use in the United States during 2010, a decline of 13 percent from 2005 and a substantial change from the level of about 400,000 reported from 1985 to 2005.
Consistent, historic, and up-to-date surface-water data, such as gage height (stage) and streamflow (discharge), collected at major rivers, lakes, and reservoirs, downloadable from the USGS National Water Information System as graphs, tables, or files.
Upcoming interagency study to assess status of ecological conditions, their relationships with contaminants and nutrients, anthropogenic factors affecting these, and develop models that may predict these ecological conditions.
