Flood Information

When flooding happens, USGS field crews are among the first to respond. During and after storms and floods, USGS field crews measure the streamflow and height of rivers and ensure the accuracy and reliable operation of streamgages. In addition to the permanent gages maintained by the USGS Water Science Centers, additional temporary gages are often deployed during a flood to measure, record, and transmit additional data about the event. Field crews continue to work as waters recede, gathering high water marks for post flood analysis. All of this data is crucial for such activities as the issuance of flood warnings and characterization of flood hazards to mitigate future damages.

WaterWatch (http://waterwatch.usgs.gov) is a U.S. Geological Survey (USGS) World Wide Web site that displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States. The real-time information generally is updated on an hourly basis.
