Mississippi River flooding

The Big Picture shows Mississippi River flooding "The Mississippi River and tributaries continue to rise, reaching record crests, and the worst may still be to come. Portions of Missouri, Illinois, Kentucky, Tennessee, and Arkansas are under water, with more to come. Pressure on levees led the Army Corps of Engineers to blow up a section below Cairo, Ill, inundating 130,000 acres of farmland while saving the town. As a bulge of river water makes its way downstream, levees are stressed and rivers that empty into the Mississippi have no outlet, backing up and flooding even more land. The bulge will reach the Delta later this month, and millions of acres are threatened. -- Lane Turner (33 photos total)"
