re: Lower Mississippi River to be dredged to 50 feet. (not a river pilot thread)
Imagine the guy in the front of the ship with a 50 foot pole hollering...yeah Captain Jeffsdad, its ok here! Naw, ain't gonna work for me. I've been stuck in Fish Lake off the Ouachita River before, ain't gonna happen again.

The rest of the crew just gives that pissed off look as they put on waders to jump in the water and try to walk the boat out.

Just have to point out that JBE gets some credit here for being commercial and not following the liberal environmental playbook.
If he were the liberal freak like some here say he is, he would have never supported this.
He would have come up with some endangered species that needs protection from dredging.

Interesting stuff. These are old problems we're continually fighting. You might find this interesting.
Eads vs. The Mississippi and The Army
quote:

WHEN MUD AND SANDBARS were choking off the Mississippi— America’s highway—from the ocean, James Buchanan Eads had the solution. But to implement it, he had to overcome an adversary even more implacably hostile than the river itself: the Army Corps of Engineers.


quote:

The Corps had tried a variety of solutions over the previous forty years.

None had succeeded.

Only recently the Corps had given up and pronounced the sandbar a permanent, immovable barrier. It planned to outflank it by building a canal to connect the river to the Gulf. The canal idea had gained nearly universal support throughout the Mississippi Valley, especially in New Orleans.

So Eads’s words were controversial, even inflammatory. He called for constructing jetties—two parallel piers stretching far out into the Gulf. They would narrow the river and increase its current, which Eads believed would be enough to cut a new channel through the bar.

He had watched this very thing happen in St. Louis in 1837. Sandbars had grown into tree-covered islands so big that they threatened to cut the city off from the river.

Robert E. Lee, then a captain in the Army Corps of Engineers, built a jetty into the river that directed the force of the main channel against the islands.

They quickly melted away.

Now Eads wanted to do the same thing at the Mississippi’s mouth, in defiance of the canal advocated by the Corps and its chief.

And more opportunities to use that silt to build land and restore marsh. If they will do that, as opposed to dumping it in the damn ocean.
I don't know where they have been placing dredge spoil from the passes. But from Belle Chasse to BR they typically pump the spoil to the side(s) of the channel (but still in the river).

I'd like to know how many pipelines (if any) will have to be replaced to accommodate the deeper channel - and who will pay to replace them.

They have built over 6,000 acres of land in the birds foot delta through the beneficial use of dredge material program with the Corps.

I don’t think there are any pipelines that need to be moved. The river has been authorized to 50ft for decades so pipeline owners go much deeper to avoid moving in the future.

in perspective a 1200 foot ship with a 1% elevation run out tolerance for the bottom requires 12 feet depth to manage uncertainty
