your right but the problems this year was that because of all the local rain we had earlier in the year had the back water flood control areas full before the river ever started coming up. when the river water got here there was no where to put it. the pump system would allow the corps to pump the flood control areas out into the river before the river ever rises. the river has actually been much higher than this in the past without near as much destruction
