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 to 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 activities such as the issuance of flood warnings and characterization of flood hazards to mitigate future damages.
