Missouri National Guard soldiers, Staff Sergeant Kevin Ackley, left and Staff Sergeant Allen Godsey look at floodwaters from the Missouri river overtop a levy near Brownville, Neb., Sunday, June, 19, 2011. When the Missouri River reached 42.5 feet, or 899 feet above sea level Sunday morning, the Nebraska Public Power District issued a flooding alert for its nuclear power plant, Cooper Nuclear Station. Cooper, located near Brownville, is at 903 feet elevation, and NPPD officials said the river would have to climb to 902 feet at Brownville before officials would shut down the plant.
