What kind of damage could we expect if this thing failed—flooding homes, businesses, and refineries?
A torrential flood would improve Port Allen.

There are bridges over 100 years old that still carry traffic.
Dawg, we have 60 year old infrastructure standing between modern aviation and total catastrophe.
I’m not saying any of this is great, but let’s just put all of this aging infrastructure into perspective.

So you are saying that an evil villain would blow that up and places south of plaquemine would go under water?

it happened, I bet it’d be “relatively” easy to plug. Unlike a levee breach where the whole thing is just eroding and getting bigger as you try to plug it up.
You ain't stopping water until it levels out. Doesn't matter what the hole you have to plug is.

This is a canal lock and not a floodgate. The river was far higher in the last 20 years.
45.48 feet on May 18, 2011.
45.18 feet on April 29, 1945 and May 16, 1922.
44.58 feet on April 16, 1945.
44.48 feet on February 28, 1937.
44.35 feet on April 16, 2020.
44.18 feet on March 18, 2019. This marked the seventh highest crest on record and the second highest since 1945.
43.78 feet on March 19, 2018. This was the ninth highest crest on record dating back to the 1880s.
43.28 feet on January 18, 2016 and January 17, 2016.
43.13 feet on May 12, 2011.

The Old River Low Sill Structure (The original structure) is about to undergo a massive rehab. During the next low water season
Everyone here stating that things were built better 70 years ago, maybe....Designed better? LOL no.
The original designers did not put in bulkhead slots in the low sill structure for dewatering purposes, therefore the gates and seals haven't been assessed since they were initially deployed.
MASSIVE steel structure are going to have to be constructed and installed on both sides of the structure, 2 gate bays at a time, to maintain the structural integrity and stability on the structure since it took a huge hit in the '73 flood when the wingwall collapsed and nearly undermined the structure.

a lock not a flood gate - HUGE difference - if one broke the other could stop the flow. Happened on harvey canal in 70s.

This is actually what pisses me off about my retardedly high flood insurance.
The only way I could ever flood is if the actual levee itself fails. And even then... It would have to flood to a depth of 13ish feet in the 90k acres between me and the ramah levee.
The entire Mississippi river could be redirected through a one mile stretch in the levee... And it would still take 16 or 17 days for that to happen. And that assumes zero water continuing to flow south.
