It's very imaginable. One of the biggest rivers in the world and we're arrogant enough to think we can make it do what we want it to do.

You're kidding yourself.

Looking at around 2 million barrels of refining capacity offline almost indefinitely (possibly immediately). Not to mention all the other petrochem facilities.

Doesn't even touch on the destruction through Morgan City that would disrupt upstream.

It would find a new path to the gulf and deepen that path, and we would build new docks to offload and onload ships and barges.

Rivers find the easiest path. The current MS river route through BR and NOLA is not the easiest path.

One good thing if that happens. Traffic is more easily fixed. ??


Traffic is more easily fixed because there is no traffic. In this scenario, I-10 over the Atchafalaya basin and 190 are both washed out.

Which refineries will be flooded?

There literally is “going back”

The Corps will throw everything at it. In fact, it has happened before. I worked closely with the Corps 20 years ago when I worked at the Hydro plant. No one is going to let that river change course.
Anything is possible, but no resource would be spared. This story comes up once a year it seems like. Must be a slow news cycle.

Probably referring to water supply

It’s not about them being flooded, it’s about producing potable water for the facility.

You understand this is what rivers do right?

The slow down to come up the Mississippi would be sped up and something automated like LongBeach CA might result.

On the salinity of Pontchartrain. I'd never tell anyone to drink directly from Pontchartrain, but I've accidentally tasted it near the Causeway and it's definitely salty. I've also tasted it at the western end of the Lake where the barnacles are few and far between and it is so much less salty.

Lake Ponchartrain isn't really a lake. It's a tidal estuary.


Yep. But I was thinking the lower salinity would make the conversion to potable water easier.


That's very possibly correct. I don't know how desalination plants work, but intuitively, it seems like less salt would be easier to remove than more salt.

It plugged the mouth of the river for about ten days. There were probaly about 100 ships on anchor in the Gulf trying to get in. Ships from around the world.


Take a ride down Highway 23 through Plaquemines Parish all the way down to Venice. From the highway, You’ll see tons of ships anchored in the river waiting to go upstream.

Most people traveling from New Orleans to Lake Charles wouldn't consider having to take I-20 as an easy fix.

Refineries being under water won't be the problem. Receiving crude and shipping finished product will be the issue.

Every utility and plant that uses river water for cooling or process will have huge problems. That'll be a bigger issue than municipal water supply.

I lived just upstream of the Madisonville bridge and the water tasted fresh, but I caught crabs off my dock and got barnacles on anything left in the water.
