It's a right wing lie. I found this:

In early 2004, as the cost of the conflict in Iraq soared, President Bush proposed spending less than 20 percent of what the Corps said was needed for Lake Pontchartrain, according to this Feb. 16, 2004, article, in New Orleans CityBusiness:
The $750 million Lake Pontchartrain and Vicinity Hurricane Protection project is another major Corps project, which remains about 20% incomplete due to lack of funds, said Al Naomi, project manager. That project consists of building up levees and protection for pumping stations on the east bank of the Mississippi River in Orleans, St. Bernard, St. Charles and Jefferson parishes.
The Lake Pontchartrain project is slated to receive $3.9 million in the president's 2005 budget. Naomi said about $20 million is needed.
"The longer we wait without funding, the more we sink," he said. "I've got at least six levee construction contracts that need to be done to raise the levee protection back to where it should be (because of settling). Right now I owe my contractors about $5 million. And we're going to have to pay them interest."
