re: Looks like Landry is going to tank the mid-Barataria diversion.

Not sure why this is being downvoted. It is accurate. Once we added the levees, sediment stopped being distributed in the basin. The outflow was essentially to a drop off. Then as we dredged, while we knew we were losing land, we took the sediment offshore and…dropped it in deep water.

I encourage folks to get to the center for river studies and see the interactive model in action. When you see the magnitude of what we are dealing with, you will realize dozens of these sediment diversions combined with beneficial use dredging would be needed to just slow down the bleeding. Ain’t gonna happen.
Also, unlike 100 -150 years ago, there are locks and dams all along the Mississippi and the tributaries that feed her. The sediment load isn’t what it was. Land mass is being formed in and around these structures upriver from sediment accumulation. It isn’t making its way to SE LA. Barge that down to us as well.
