Material Detail

This web site provides access to the river and stream water flow information that is collected in the United States. Current levels are compared with historical streamflow records for Real-Time (over several hours), Daily, 7-Day Average, and Below Normal streamflows. Colored maps and graphs show the data by different time periods such as day, week, or year. Relative wet and dry conditions are easily determined. Access to key related National Weather Service features is also provided.
