This is just not true. Most of the damage being done is backwater off river flooding - other side of the levee- which cant go anywhere because of the high river. Opening Morganza will not only lower the river but almost overnight take this backwater out.
I think you are mistaken on the conversation. They are talking about the water around Pierre Part, Stevensville and Morgan city area. Opening the Morganza will not in any way help these areas and could in fact hurt.

River changes course for good
Morgan city is gone
Mississippi River we currently know (downstream of ORCS) will begin to silt in
Navigation and shipping is vastly affected.
Salt water wedge pushes up the Mississippi River to nola possibly cutting freshwater supply all up and down the river
Sooooo not good
nope to every one of those
Scaremongers seem to forget the MS ran freely down the Atchafalaya for 150 years before the ORCS was put in place and the port of NO was the nations largest during this period.
It is almost like history does not exist for some folks.

It is not your opinion that deceasing Q in the MS River as we know it would caused increased shoaling?
Posted on 5/23/19 at 10:34 am to cave canem
So will opening Morganza slow the flow rate of the Red River & Black River that has finally seem to crest since so much water will be coming into the Atchafalaya River now?

You don’t know what you are talking about. The Mississippi River has changed course many times and eventually it will again. This is the main concern with the control structures and the morganza spillway.

Of course it will, just not at the doomsday scenario level so many seem to believe.

Can anybody get a map and put a pin where the barge goes. I just wanna see how this works.

Yeah, I'd like to see that too. I had great grandparents that lived in the village of Bayou Chene before the '27 flood.

Nope. There is no risk that the river will change course if the Morganza Structure is opened. I dont know where this idea came from.

This is a great book on the flood. I can't remember the name of it but there is one that specifically covers the flood in Louisiana. An old baw from Arnaudville was telling me when the water came up there were gators everywhere. His parents killed a bunch and put gator meat in their saurkraut then canned it.

Yeah, with that thinking, opening the Bonnet Carre could change its course too.

I think people are getting confused between the Old River Control Structure and the Morganza Spillway.
Posted on 5/23/19 at 1:36 pm to doublecutter
Yea most of the time the fore bay doesn't even have water.

What role does bayou lafourche play in spillway management. It’s tiny.
But t starts at donaldsonville but doesn’t connect anymore to the Mississippi. I see a pump station but the levee has cut it off.

Holy shite, so what you're telling me, is that even though the atchafalaya is close to the coast that the basin will be handling so much water that it will STILL push back up into the verret/palourde basin??

zero
they probably pump water into it from the river but you aren't going to get any kind of significant flow in bayou lafouche to put a dent in the Misissippi flow. Similar to Bayou Plaquemine.

Yes, I think the last time they opened the morganza spillway they had a 5 foot difference in water level between the two sided of the barge.
