USGS Data Collection Activity -Birds Point-New Madrid Flood



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 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 level near Cairo to drop nearly 1/2 foot during the first hour of operation. Two outflow breaches were initiated at 12:40 pm on May 3 and at 14:39 on May 5, 2011. On-site USGS crews are providing vital floodway data to the USACE and other agencies.
