What? How will that help?
We have to wait until the next major hurricane and then the feds will blow up the levees.

When was the last time that the New Orleans metro’s water supply was affected by saltwater? Serious question because I don’t know. I just know it wasn’t any time recently

Why are you hung up on New Orleans?
New Orleans won’t be in any danger for another 40 days.
Get off the crack Capt

Seems like it was almost to the FQ within the last 5 years.

Because New Orleans is literally mentioned in the OP. Nobody cares if Port Sulpher has drinking water
And according to the Corps of Engineers, a sill has only had to be constructed 3 times since the river was dredged to 45ft. : 1988,1999,2012. Certainly doesn’t sound frequent to me.

Commander Cullen Jones with the Army Corps of Engineers laid out a timeline for potential impacts:
Belle Chasse - Oct. 13
St. Bernard - Oct. 19
Algiers - Oct. 22
Gretna - Oct. 24
W. Jefferson - Oct. 25
Carrollton - Oct. 28
E. Jefferson - Oct. 29

Just saw Sheriff Lopinto make a solid commons sense Facebook post trying to calm Jeff Parish residents fears and try to get everyone to quit stockpiling water.
He ended with advising everyone to relax and enjoy the Saints/LSU game this weekend and drink beer to conserve your water. LOL

How do they construct this? Don’t make me google it.

The last really severe event was in 1988 and this year's event looks to have similar results. So its forecasted to the worst case in about 35 years. But that doesn't mean it hasn't happened in 35 years. There's some degree of salt water intrusion into the river almost every year.
The USACE's sill has been built multiple times over the years. It usually works. This year it isn't. They're in the process getting it raised to 30 below sea level. They intend to cut a notch in it to maintain a shipping lane as they do not want to severely impact maritime traffic. It will be alternating one-way traffic through the notch until we get some rain upriver. I believe COL Jones stated that we need in the range of 10". (TWSS, for those with a puerile sense of humor.)

They dredge silt from downstream and place it perpendicular (levee to levee) across the river bottom, forming a berm or sill.

You folks understand that the Mississippi valley drought is a direct consequence of eliminating Carbon. When fuel gas/oil is burned there are two byproducts CO2 and water. Eliminating co2 in the atmosphere necessarily eliminates water also which we all know is rain that flows down the Mississippi.
My data to corroborate the above info? Asia and Africa have done almost nothing to curtail co2 and look at the flooding occurring in Libya, Pakistan, India . Bangladesh Philippines etc

That is literally impossible
I believe they intend to use more than one barge. They'll be cleaned of chemicals, oils, and other pollutants; but the water will still be treated at the treatment plant.
The treatment plants will still use some river water. The barged water will be used to dilute the river water to acceptable salinity levels.

You aren't thinking 4th dimensionally.
Seriously though, y'all are trying to replace all the water. You don't have to do that. You just have to blend it down to acceptable levels.

Do you have any idea how hard it is to find 15 clean 30k bbl tank barges right now?
Do you have any idea how much it costs to clean a dirty barge and the time it takes?
We’re trying to find open hopper barges that will carry close to 600k gals but they aren’t readily available bc it’s cutting season and those barges are $1000 a day

The notch is already there. 600 feet wide. One-way traffic has already started

Thought the notch was to be in the Belle Chase sill not the myrtle grove.

Nope. I have no clue about barge day rates or cleaning costs. I know you're involved in the maritime industry (and somewhere above a tugboat deckhand), so I expect you might. I just know what COL Jones said in the presser yesterday.
I think the current plan is to use multiple barges, to multiple treatment plants, with capacities between 100,000g and 1,000,000g for fresh water. The water would be delivered to augment, not replace, the salty river water; diluting it to a safe salinity.
I would expect that Plaquemines and St Bernard would see the first deliveries and Orleans and Jefferson to see deliveries after. But that's just speculation on my part.
