One key change that was being looked at involved altering the amount of water allowed to be diverted through the Old River Control complex to the Atchafalaya River. The amount of flow through the complex on an annual basis — 30% of the combined flow of the Mississippi and Red Rivers — is locked in place by congressional mandate.


Well good fricking luck with that.

Also, I’m not sure if I believe the nutrient pollution thing. How is Mississippi River water from Lake Pontchartrain any more polluted than Gulf water?


Because it contains runoff from half the country.

Every farm, chicken plant, aggregate mine, chemical refinery, nuclear plant, and any other kind of industrial or agricultural company that exists dumps shite into water that goes into the Mississippi river.

I remember arguing with an ecology professor about this at LSU.
I stated nature will always win.
He disagreed.
I stated that nature will always be here, humans will not.

The Mississippi folks just want reparations, free money, lawyers at the trough.

The oyster guys knew the weather risks.

for the greater good and all that. Who paid for that long article? Follow the money.

Could view it as humans could launch a couple hundred nukes and kill all of nature.

Yes, of course, but that doesn’t address my question.

I asked why River water from Lake Ponchartrain and Lake Borgne are any different than the River water from the Gulf.

The River normally dumps all of that water into the Gulf in Plaquemines parish, and then that water travels along the Gulf Coast in Misssissipi, Alabama, and Florida before going into the Atlantic.

Perhaps it’s less concentrated by the time it makes its way from Plaquemines Parish as opposed to St. Bernard Parish.

Because it doesn't wash directly out into the gulf of Mexico.

It goes into the Mississippi sound and kills everything that lives there.

My problem with everyone of these articles about the Mississippi River is that it always revolves around fishermen or oyster men who have grown accustomed to a primarily saltwater fishery that was mainly fresh to brackish before man intervened and closed the river to its current path.


This is my issue as well.

I didn't read all of this article but a lot of them mention marine mammals (dolphins) being affected. Them frickers have tails and will swim to fresh water. We don't need to worry about them.

No.

Nature would change for a time, but all humanity would die.

The planet might be dark for hundreds of years, and much of nature might be dead for thousands, but humankind would be erased, and eventually, the planet would recover.

Earth is 4.5 billion years old. A few thousand years is nothing.

So it’s less concentrated when the river water arrives from the mouth of the river in Plaquemines?

I would be interested to see some actual studies on this. Very interesting topic.

That's not how that works.

You flood pontchartrain with nasty river water, and it flows directly into the sound and turns salt water into brackish water.

Anything living in the sound dies. Every time Bonnet Carre opens, dolphins and other marine life washes up on Mississippi beaches and the oyster beds die out completely.

No. The Ms river exits its mouth into the gulf.

When the spillway is opened, it also runs into pontchartrain, then borgne, out into the sound.

The barrier islands between the sound and the gulf don't allow water to move as well as it would open the open gulf.

Basically, if your dog starts shittin and pissin in your neighborhoods stocked lake, no biggie. If he does the same in the tiny koi pond on your patio, that's a problem.
