USGS Flood Information   

The USGS provides practical, unbiased information about the Nation's rivers and streams that is crucial in mitigating hazards associated with floods. This site provides information about the USGS activities, data, and services provided during regional high-flow events, such as hurricanes or multi-state flooding events. The USGS response to these events is typically managed by the National Floods Specialist.

Prior to the arrival of Hurricane Sandy, USGS technicians deployed non-transmitting storm tide sensors and wave height sensors and real-time rapid deployment streamgages (RDGs) along the Northeast coast.

The data are available on the Hurricane Sandy Flood Event Viewer. The viewer provides location information, site photos and data for storm tide and inland flooding. Data will be made available as soon as possible following the storm.

Critical user information.
