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.

This section contains information about active and recent events tracked by the USGS National Floods Specialist. Streamflow data is vitally important for our partner agencies to forecast flood magnitude and timing, operate flood control systems, and manage emergency response. In addition, USGS also coordinates collection and dissemination of geospatial imagery and map products used for flood response and evaluation.
