How deep is the river at ORCS?

That didn't get filled with rock and grouted around the time the auxiliary structure was built? I read in one of Sid's links that maximum head is much lower now (like 22', instead of 43'. Trying not to exceed 19') than as originally designed, but it made it sound like they replaced the damaged/destroyed wing wall and filled the hole. Maybe I misunderstood.

The original design head differential for Low Sill was lowered bc they can operate Auxiliary.
Gotcha. My understanding was that it was lowered because even after the repairs, the structure was still compromised, relative to its original design capacity.
Sid in Lakeview posted two USACE links. The second was a brochure on ORCS. It was pretty interesting for someone who knew very little about the complex. It also gave a timeline of when the various facilities were constructed.
There's a pic of the '73 event as it was happening. You can see the emergency road built were the downstream wing wall was destroyed. It's an enormous scour area. I believe they said that when the area was de-watered after the flood that 40' or 50' of 90' pilings were exposed by scour. I bet there were some engineers shitting bricks when this was happening. Can you imagine if the whole structure had failed? I wonder how much warning people downstream would have gotten.

There's too much dirt in the Mississippi River
I guess that is why they call it the Big Muddy

Dirt?????
Dirt is the least of the issues with the Mississippi. For christs sake, there is dead bodies, toxic barrels, toxic shite from floods up and down the river, and anything else you can imagine in that fricker.
And ur worried about dirt???????????????????????????

If you own a dredger you are set for life. they pay dredgers to dredge the river 365 and just deposit it back into the water column. Look at the one West of Downtown BR. Always there. Just moves around. Just depositing back into the water column. Just getting paid.
The Corp is basically against someone paying for the extra pump/pipe to deposit to a different area then what the Corp has permits for. So the deposits get dredged to one location then you have to dredge from there to the location you want. When it would have been cheaper to just reroute the first dredges pipe.
Hey, it's good enough for government work.

I think I read MC is ~143 river miles from ORCS, versus ~415 to the current mouth of the river. I imagine the water would spread out in a pretty wide sheet, as well.

The wall that failed was replaced with boulders. Go on Google Maps Satellite and you can see the remaining wall.

And thanks for the link. I'm sure I'll find it interesting.

I was friends with a world-renowned sediment expert (God rest his soul). Now, I'm no expert on this topic, but the little I gleaned from our conversations is that proper design of diversions will carry the sediment away and eliminate, or greatly reduce, the need for dredging. The problem with most of the work by the Corps of Engineers on the Mississppi is that historically they have not put diversions in the right locations or designed them properly. This is in part due to poor engineering analysis, but there is also a political element pertaining to which projects get done and where. Many were absolutely useless and were never going to accomplish the supposed goal. Our corrupt politicians can screw up anything.

BP Money to LA
I'm pretty sure we have no idea what to do with all the BP money, and it will likely get squandered on something stupid.

The largest chunk, $8.1 billion, will be parceled out under the Natural Resources Damage Assessment program, which evaluates and restores resources affected by oil spills, hazardous waste sites and vessel groundings. The states will receive a total of $5.3 billion under the federal RESTORE Act, which set up a trust fund to get 80 percent of water pollution penalties paid after July 2012. The foundation's grants totaled about $100 million in each of the first two years and more than $80 million last year. Louisiana's five grants include engineering and design money for two major projects to divert sediment from the Mississippi River to create new wetlands.
