when who every it was said 1000000CFS is 1000000CFS no matter what. i figured he was saying the velo would increase as the river rose and the discharge remained constant.


Wrong.

Again as the river rises so will the Discharge and the velocity.

I figured it out. I forgot to change the date on my watch at the end of the month. It's a day behind with april only being 30 days. I thought today was the 2nd


No biggie. In a previous job my morning ritual was to check stages on the Upper and lower miss and the ohio. So I always looked for the time to be current.

Amazing that no one has brought up the River Ridge/Harahan near disaster in 1973 when the Mississippi River nearly busted through the Levee by Colonial Golf Club which would have destroyed the City of New Orleans. They reinforced this section of levee shortly thereafter but the COE still has major concerns about this section of Levee. It is the most vulnerable spot on the New Orleans side south of the Bonnet Carre spillway.

As to someone else's question about what happens if it breaks through at Baton Rouge the flooding would probably run into Bayou Manchac and if it goes further south then it would be absorbed in Lake P via Bonne Carret spillway or Lake Maurapas towards St. John the Baptist.

The Gardere area is the one that everyone in BR needs to be concerned about because the sand boils there are going to be require significant emergency work to keep them from undermining the levee from underneath.

Also hearing that the West Atchafalaya may be opened before Morganza is opened if the rain continues in the Mid-west.

UPDATE: the USACE officially began to open the Bonnet Carre spillway this morning. No word on how many pins will be taken out yet though.

this is wrong. west atchafalya has little effect on the mississippi. it's main purpose is if the red river backs up or if old river structure fails. it's the last line of defense. morganza will be opened before they blow the west atchafalya levee.

This is what they are worried about in the worst case scenario which is why the West Atchafalaya is now being informally discussed.

If we get to a stage where the levees near Baton Rouge or New Orleans are possibly going to fail book that one option will be to blow a levee in SE Arkansas or NE Louisiana. I'm not saying it will ever reach that point, but the sparsely populated Delta areas would be conceded long before heavily populated and industrialized areas between New Orleans and Baton Rouge. This is assuming that levels reached that stage which they may not, and that a natural breach upriver doesn't relieve some of the situation for the lower river.

I've read the Mississippi River will crest at 65' in Natchez(my hometown). Highest ever recorded was 58.4 in 1927.

Anyone still live around there have any info on what's expected? Vidalia in trouble?

Nothing official yet released from ASCOE on the increase but probably an unofficial estimate at this point.
