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.

In addition to assisting other USGS Water Science Centers upstream along the Mississippi River, the Louisiana Water Science Center prepared for floods in their own State by deploying crews and gages to measure record flood levels on behalf of the public, the Army Corps of Engineers, and other agencies.

The 2011 Floods in Louisiana: The response efforts of the USGS Louisiana Water Science Center

USGS crews from the Louisiana Water Science Center deployed stage sensors and rapid deployment real-time streamgages in the Morganza floodway in anticipation of the operation of the floodway, which was opened May 14, 2011 at 3:00pm. The USGS also made streamflow, water quality, and sediment concentration measurements in association with the Bonnet Carre' spillway upstream of New Orleans.
