They aren't saying the river will change course due to opening of the Morganza. They are saying if the structures fail, the river could change course. The natural flow of the river would be the atchafalaya now if not for levees and control structures. In 1900, 5% of the river went down the atchafalaya. By 1950, 30% was going that way. Without human intervention, atchafalaya would have become the Mississippi sometime in the last 30-40 years.

Thanks. That's way south on Bayou Chene from where the village was. The village was close to St Martinville.

That's ORCS, not Morganza. If the Morganza structure fails, still almost no chance that the river changes course. Additionally, opening the Morganza spillway prevents it from failing due to overtopping.
Earlier in the thread, a dude asked what the negatives were to opening the Morganza spillway. Several people responded that the biggest negative was the potential for a river avulsion, which is false. Hence, my comment.

How does fore bay get water in it? Looks like a levee goes all the way around it, but I’ve never been there to actually check it out for myself.

water comes through the south end of old river and tops a smaller levee on the north side of the fore bay.

Yeah, didn't read the whole thread. 
When I said they, meant people who actually know what they are talking about like academics, the corps and people who have actually educated themselves...

I see people talking about Morganza failing from over topping. Just a thought but say that happens and you get a huge amount of water flowing through there fast enough, Im curious if that smaller levee would erode. I dont know enough about erosion or elevation but a straight shot of the river flowing through the narrows at old river into the fore bay and out the spillway for a solid month probably wouldnt cut a channel but interesting to think about

Scaremongers seem to forget the MS ran freely down the Atchafalaya for 150 years before the ORCS was put in place and the port of NO was the nations largest during this period.
do you compare some small steam boats that draft a few feet to the ships that draft 50+ feet? While i agree it wouldnt put PoNO and PoBR and such out of commission and it would silt in like. It would actually be easy to dredge it once and would give years of life before it were to silt in again since all that sediment is going down the Atchafalaya.

Comes over the potatoe levee at 36’.

Yes, I think the last time they opened the morganza spillway they had a 5 foot difference in water level between the two sided of the barge.

our camp is north of HWY 70 on Belle River
how fricked is it?

Depends on elevation, but I'm told that road is closed.

The morganza opening shouldn’t effect you on belle river because of the barge being discussed earlier in the thread.
Posted on 5/23/19 at 4:31 pm to civiltiger07
In laws live on bayou tranquile.
They got a message from the police jury that the barge is a maybe because the water is soo high. They are going to try to put the barge in. If not prepare for the worst.

Its already pretty bad down there, they should have put barge in weeks ago. Not to mention the HESCO baskets along hwy 70 which is now under water. Now they want to place them and dewater hwy. Our emergency preparedness never ceases to amaze me.

My pops lives on hwy 662 next to the the avoca island cutoff canal. Should he be concerned aswell?
Posted on 5/23/19 at 5:14 pm to lazcreek
Should have long ago been put in. If nothing else it would have given people more time to sandbag and stuff.
They really need a control structure right there

Can someone explain the significance of a barge? I have no clue about this and am curious why this is being discussed. Who puts it in and how does it help.

It’s being used to close off a channel
