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

If NBR floods,SBR and St G is SCREWED.

See the map (NBR= light color, higher elevation, SBR, darker color)

I recognize the irony

Well I've lived half my life south of 10.

is there a possibility that certain areas of br or nola could flood? sorry haven’t been keeping up with this at all and it’s hard just skimming this thread to get the right info.

don't know if it matters but...

That's good but I honestly think the Missouri River, Arkansas and that Ohio Valley feed is going to play hell. It's just not stopping up there.

I don’t know how germane to the topic this is, but with all the hyperbolic conversations about the river changing courses and seeking a faster down the channel, why are there large sections of meanders in the Baton Rouge-Donaldsonville area where the river has not cut through them creating shorter path.

Looking at the map below there is one spot where the river narrows very tightly and goes around a large bend.



I know with a high water event like this, these bends between the East and West Bank levees are underwater. So there is water where there are trees in the photo.

Is the USACE doing work around these bends to keep the main channel where it is for navigational purposes?

Those bends get closer and closer over time. The outer edge gets eaten away and the inside edge gets silted in. Left alone, these spots will eventually breach and you’ll end up with an oxbow. Eventually, the mouths of the oxbow will still in enough and they become isolated (lake St. John, etc.) The levees and reinforcing by the USACE keeps these areas from scouring.

In this specific case, if there’s no levee in that location, the river will “straighten out” sooner or later

Just watch the above video

fricking muskrats, it is all their fault.
