Oh, and I believe those shuck and jive artist maintaining the levees in NOLA were the Army Corps of Engineers. 
Nope.
ACE had responsibility for building them. After they were built, they were turned over to the state and local governments for "operation" and maintenance. They were maintained with federal money, but the money was signed over to the various and numerous levee boards that oversaw the individual levees under their jurisdiction.
Supposedly the way the boards were set up, they were quite the sweet deal, if you could get on one; and if some of that guv'mint money just happen to get left in your pocket when you went to contract out the levee maintenance, well, it was just part of the costs of doing business, right?
