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.

  • 2016 Flood Events

2016 began with unseasonably wet conditions across much of the central and southern States. Multiple record-setting floods resulted, especially in Louisiana where spring and summer flooding kept the Lower Mississippi Gulf Water Science Center estremely busy. Hurricane Matthew finished off the strong flooding season for East Coast States in October.
