Corps Says No Benefit to More StorageRetha Colclasure | 4/13/2012
So would extra flood control capacity have helped prevent flooding? The Corps says not really.
They released an analysis of how additional flood control storage would have reduced the risk of flooding during runoff events like what happened last year. They say there would have been no significant increase in the average annual flood benefits for any of the six possibilities they studied.
The Corps also points out that increasing flood control capacity would have negative impacts on other uses of the dams, like generating hydroelectricity and providing recreation.
