Monday, January 17th, 2011 — River forecasters for the National Weather Service underestimated the flood level that a major river would reach during Nashvilles fatal May floods because they relied on inaccurate data from the U.S. Army Corps of Engineers, the service concluded in a report. The report found that forecasters ignored two models that showed more accurate flood predictions for the Cumberland River in favor of a model that relied on inaccurate and untimely information from the corps.
