re: Morganza Spillway may or may not open for a 3rd time -- lack of clear info from ACoE

So you want a few billion dollar investment for something that may be 50-75 years away or more?
I'm sure they will get on that.

How much more water can the Gulf take before it starts flooding Venice and the surrounding areas?

Fun recollection from my youth. We used to go to Laplace every weekend to see my grandparents. They lived next to river road and in 73 the water was what seemed to me at the time inches from the top of the levee. They opened the Bonnet Carre spillway and it was so high it covered both ends of the airline bridge, so we couldn't go to my grandparents for a couple of weeks (I-10 wasn't finished yet). They never closed the gates back then until the water stopped flowing, and it filled the spillway up with near white sand that took years to dig out. Everyone was building baha bugs to ride the giant dunes it left behind for years. It got loaded with sand again in 75. I can definitely see the river silting in its channel if the velocity dropped off in just a few months time.

Rain predicted for pretty much the entire upper watershed of the Mississippi River thru 5/27.

It might be two weeks away too. Then what will you have to say? It is GOING to happen and when it does there WILL BE major economic disruption.
But we can minimize it with prior preparation. Pay some now or a whole lot later.

It's always been 'maybe' two weeks away.
We can't get a pipeline built without the Supreme Court getting involved. And you want to relocate major infrastructure like LOOP, Port of South LA, and interstates that we can't maintain much less move.

The good news is that the area up there can handle it. The LA threat is essentially rain in the orange (Lower Mississippi), light blue (Red River), and dark blue (Arkansas Basin) watersheds, and that's in order of how big of a threat they are.
The Mississippi River @ Memphis can handle an additional 200k cubic feet of water per second before it gets back to it's May 14th crest. Rainfall in the other basins would prolong the high water levels in LA, but they're not a major threat, for now, to increase water heights.

I heard a rumor that once the Morganza opens that water levels bin Belle River might rise 9-12 inches. Anyone have a way to validate that?

Not with them sinking the barge to block off the Chene. And they decided yesterday to sink the barge. They’ve already located the barge and the work has already started.

It's not a one to one correlation, but the Army COE is supposed to release a projection if/when they decide to open Morganza.
The local rep for the area said it would likely be around half a foot higher than current water levels with Morganza opening, so we'll see.

It starts to help pretty quickly, but it's got it's own issues too, rainfall being the primary one. It's why they don't leave it there permanently.

Good. I need a snorkel at work.

They’re going to build a permanent structure where they can open and close the gate when needed.
Here, this will explain a lot.

I wonder how much of the ability to handle the water stems from the reservoirs we have up north. A lot of them are almost at capacity and they are going to be forced to start releasing a lot of water, and there is a lot more rain in the forecast. The ones around me in NE Kansas are all at or near the record levels set in 1993. After the rains we get this weekend they will set new records. All of this water is going to make it's way down south.

Yeah I'm familiar with the project. I'm pointing out the barge doesn't stay there year round, and the gate won't be closed year round, because of transportation and drainage issues it causes.

Yeah but it's going to be released after the crest has already passed. The river in Memphis is down 200k cubic feet per second from its crest. It could take that much water and still not rise above its highest levels this year. 200k cubic feet per second is basically a third of what typically drains through New Orleans in the fall.

yeah I’m familiar with the transportation and drainage issues as well as the sinking barge projects and Bayou Chene. It’s only been my backyard for the past 45 years. Posted on 5/25/19 at 4:37 pm to tgrbaitn08
