re: Miss River Flood Thread 2016, river back on the rise again.......

I find it curious that New Orleans gets to 17 (flood stage) on 1/9 and stays there for weeks. Is that because it will be maintained at 17 by spillway openings, or is that where the model tops out? The levees are supposed to be 20'.

This is the 2nd or 3rd (open to debate) - 500 year flood in the last 23 years. Most of the river surveys are 40-60 years old. The farmers in the Fore Bay were in the process of trying to get the corp to do new surveys when this started. The Mississippi valley has changed a lot in the last 60 years. It is time for new surveys.

If my memory is correct some of the surveys are 80 years old.

All of that kind of talk is why I'm not posting on the thread on the OT

You talking about if everything blows out?

We actually want those levees to fail up North as it will allow for a slower rise down south. It will also lower the height of the water for some of the cities up North too.

No, this is sort of quick thread hijack. Would it not be beneficial to remove the levees south of Bell Chase from a strictly helping with coastal erosion standpoint. Nothing to do with the high river right now.

Yes it would be beneficial to helping re-sediment the marshes but not to the deepwater draft shipping vessels who need the bottom scour to keep the river navigable. .

I wish the Red had a spillway.

It does. It's called avoyelles parish.

For those of you counting that is saying that the levees in New Orleans will be at 17 feet for AT LEAST 18 days. This is a significant amount of pressure on our levees. There are some real problem issues with the levees on the west-side of the Mississippi River within a 100 miles of New Orleans that have been leaking underneath the levee for years.

If we don't the Mississippi will. Might be this year. Might be is 100 years. New Orleans continues to sink & we continue to lose coast line. Worst case scenario- Mississippi blows out. Salt water comes in & we get hit with a major hurricane this summer. The gulf is warm.

Errett says the Corps is already preparing for flooding in the New Orleans area.

Huh, river under the river? What is this you speak of? I fancy myself a decently informed person and have never heard of this.
