Def something to watch. The 1927 flood was one of the worst disasters in US history. Hope the levees are all up to snuff. For anybody interested, the book Rising Tide is a good read on the '27 flood and all the politics and aftermath.

I have that book. Read it more than once. Good book.

Being that it is supposed to crest at 47.5ft on 5/21, and the lowest part of the leeve in downtown baton rouge is 47.3ft...... yep, it ain't going to be pretty.

I wonder if they'll open the Bonne Carre spillway soon?

What would that do? How does it work?

they have recently blown levees up north and they are not beyond doing that here.. hope everyone has a boat and a plan.

I am not sure how "soon", but that is the word on the street. morganza would be an option too..

Since a major flood on the Mississippi River has the potential to overtop levees in New Orleans, a series of relief valves have been installed on the river channel upstream of the Big Easy to allow flood waters to have an alternate route away from the river. By allowing water to pass out of the Mississippi into other waterways, the peak of the flood will be reduced, thus reducing the strain on the New Orleans flood control system.

The Bonnet Carre will be opened, although the design capacity is much less than the Morganza Floodway. They won't open the Morganza Floodway unless they feel it is a last resort due to the flooding of farms and homes that would result. It has only been opened once since it's completion in the early 40's, in 1973 I believe.

Hmm... thanks for the heads up.

It really is a site to see the Bonne Carre spillway opened up. I don't think it is an if but rather a when. I heard around the 15th.

The Bonnet Carre is like a huge temporary douche for Lake Pontchartrain too! Good bye speckled trout, shrimp, and crabs, hello algae bloom!

It's going to be ugly at first, but it comes back nicely. Ain't nature great?

we're being told that the Tensas river would serve as a relief channel should it be needed... that's good because it is BONE DRY!!!

 

[Emperor]

This has the potential to be a very big event!

The recent excessive rains in the Ohio Valley are not even figured (mathematically), into the mix yet?!?

Yikes!

Got a text that says they're going to temporarily open the new bridge in St. Francisville Saturday because the water is too high for the ferry.....
