These levees needed a lot more than maintenance. Earthen dams -- even if they are capped with cement don't have the strength. They showed diagrams on FOX of what is happening and anyone who knows about dams realizes that the pressure on these things is incomprehensible right now and they are being undermined from underneath as well as too much direct pressure on the sides. The Army Corp built huge levees in Central California years ago and they, too, failed in a big flood... lucky that mostly farmland was in the path of those levee's.

Max pressure on a levee occurs when all the water is on one side.
When I took piano lessons as a child, my first recital piece was "On the Levee" so I could learn syncopation.
