History of Engineering Old River: Confluence of the Red, Atchafalaya, and Mississippi Rivers

Daily operation of Old River Control Structure(low sill) diverting 30% of the Mississippi river's flow into the Atchafalaya river.

This used to be the only feed until it was almost washed away in 1973 and The Auxiliary Control Structure was built. Now combined, or one or the other is used to achieve flow rate capacity.

Honestly, the levees around the Atchafalaya Basin and along the Mississippi river have done more harm to nature than good. All in the name of protecting industry, business, metropolitan areas, and farmers.

One day one of these structures will fail, and you'll see a shit show that will make Hurricane Ida look like a 12volt fan.

already did. it was called katrina.

Katrina was a mere bathtub

During the flood of August 2016, a stationary low pressure system dumped 20-30 inches of rain from southern Mississippi, east of baton rouge to west of  Lafayette  in about 2 days . Millions of acres flooded along too many rivers to list.
None of that flooding had anything to do with, nor was connected to the Mississippi river in any way.

Out of this catastrophy, the Cajun Navy was born.

have they cleaned up the Cajun Navy yet? if they were any good, they couldve helped more with the capsized oil rig barge.

Last I heard there were two competing factions.
I think they ironed out their differences and formed a new entity, The United Cajun Navy

That sure is a lot of water!

They won't open Morganza until the Mississippi river reaches a flow rate of 1.5 million cubic feet of water/second at the Red River Landing gauge which is located between The ORCS to the north and The Morganza Spillway to the south.

Morganza should be utilized when flow rates reach 1.3 million. That's what the damn thing was built for, to be used!

But the politics involved from Morganza, through the entire Atchafalaya Basin (almost 1 million acres south of Morganza), all the way to Morgan city and the gulf , is a power play.
And a complicated one at that.

Certainly seems like a great waste of fresh water and silt. Considering the declining nature of the Ogallala Aquifer.

it would be far more economical to clean the coal bed methane water and inject that.

And, sail on.

Grassroots initiative at its finest. Really, I cannot overstate my respect for those guys...give me a million of those, and we could set the nation right.
