USGS Flood Information

Current Flood Information

Active and recent events tracked by the USGS National Floods Specialist. Click the Past Floods link above for previous events.

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 the flood response and evaluation.

Visit the USGS Flood Inundation Mapper, brought to you by WiM and the USGS Flood Inundation Mapping Program, to see how the USGS is developing real-time flood inundation mapping capabilities in select areas of the current floods. Or, click here to learn more about this important service.
