No. Alex thinks those dikes in NO are for show, not river flooding.

The MS river never floods here anymore, they built levees to keep it from happening. Hurricane Katrina's massive storm surge did raise the level of the river, but still not enough to over-top the levees. When the river does start getting too high due to rains and melting snows further up river, they can release water into swamp lands via the Bonnet Carre Spillway, but that rarely has to be done.

The MS River did indeed flow backwards for 3 days, back in 1811 or something like that, due to a massive earthquake, via the New Madrid fault. It created Reelfoot Lake in NW TN.

Lately it has been discovered that a lake was formed on the opposite side of the Mississippi River, in the Indian country, upwards of one hundred miles in length, and from one to six miles in width, of the depth of from ten to fifty feet. It has communication with the river at both ends, and it is conjectured that it will not be many years before the principal part, if not the whole of the Mississippi, will pass that way. [5]
