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.

Overview:

Significant amounts of tropical moisture from the Eastern Pacific and Gulf of Mexico funneled through a narrow zone across East Texas, Louisiana, Arkansas, and Mississippi to create some of the largest non-hurricane flood conditions ever recorded in some areas.

March Rainfall: Large areas across the southern midwest experienced cumulative rainfall amounts of 10 to 20 inches or more.

Inundation High-Water Mark Collection: Over 30 USGS personnel fanned out across Lousiana in support FEMA efforts to identify flooded areas. The USGS Flood Event Viewer linked here shows locations of sensors and data collected during and immediately after the event.

Check out this new publication: Identifying and Preserving High-Water Mark Data to learn more about how USGS personnel collect high-water data!
