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.

USGS archive for New Madrid Floodway data collection

In response to dangerous flood levels near the confluence of the Ohio and Mississippi Rivers, the US Army Corps of Engineers (USACE) activated the Birds Point-New Madrid floodway (New Madrid Floodway in USGS literature) at 10:03 pm on May 2, 2011 by detonating explosives along a stretch of the Mississippi River levee just downstream of Cairo, Illinois. The resulting inflow of water into the 130,000 acre floodway caused the Ohio river stage near Cairo to drop nearly 1/2 foot during the first hour of operation. Two additional inflow/outflow breaches were initiated at 12:40 pm on May 3 and at 2:39pm on May 5. The USGS provided vital floodway data to the USACE and other agencies.
