The Omaha World-Herald reports that some are questioning the U.S. Army Corps of Engineers' competence at predicting and managing the historic floodwaters on the Missouri River, now threatening the Fort Calhoun nuclear power plant. The article reveals that a cooler than expected spring in Montana may have prevented the floods from being even worse right now -- melting of a historic snow pack has been delayed. The article does not report how the summer's heat melting that remaining snow pack will impact downstream river levels. The criticism of the Army Corps of Engineers also begs the question, how much can we trust the agency's assurances that the six major dams upstream from Ft. Calhoun, Cooper atomic reactor in Nebraska, and Callaway atomic reactor in Missouri, will not breach?
