The corps said the break in the Birds Point levee would help tiny Cairo, Ill., by diverting up to 4 feet of water off the river. Just before Monday night's explosions, river levels at Cairo were at historic highs and creating pressure on the floodwall protecting the town.
For the Missouri side, the blasts were likely unleashing a muddy torrent into empty farm fields and around evacuated homes in Mississippi County.
Brief but bright orange flashes could be seen above the river as the explosions went off just after 10 p.m. The blasts lasted only about two seconds. Darkness kept reporters, who were more than a half mile off the river, from seeing how fast the water was moving into the farmland.
