No, the lost bottomland habitat, narrowing of the channel and increase in the river bed height has mostly taken place in the last 10-15 years.

quote:that's like 30 million cubic yards. For reference, the Corps dredges around 8-12 million cubic yards to keep the crossings between Baton Rouge and New Orleans navigable each year...so it would be like 3-4 years' worth equivalent dredging. They would need to phase it since they would disturbance dredge and dump the sand back into the water column in deeper water. They also would have a compounding effect of needing to dredge the same sand once it makes it down to the crossings south of Baton Rouge. So, not cheap, but pretty feasible engineering-wise if you phased it over something like 5+ years.

I dont really feel too bad for landowners bitching about loss of bottomland hardwoods on the batture...those were crazy high river years, an act of nature, shite happens and your land is in a floodway.

what is actually keeping them from dredging it?
The inability to collaborate, budget, finance or manage a project of that size.

My view is that thus far the Corps of Engineers has managed to postpone the inevitable because when man fights nature man will eventually lose 100% of the time. The problem as I see it is that we are in too deep to turn back. We must continue to try.

Like when a river wants to run the most efficient course?
This is bad money chasing bad decisions, rinse, repeat

The lower river parishes need to start working on that pipe to bring in freshwater for household use.

Wouldn't managing the transition to the Atchafalaya channel be the more prudent and responsible solution?

The increased sediment dropping out would in theory lessen the the channel cross section, thus reducing flow and causing a backup that extends upstream.
This is also why we would eventually lose Morgan City and surrounding communities if the Mississippi is successful in rerouting down the Atchafalaya.

It's also been filling in the Atchafalaya basin with sediment ever since Capt Shreve connected the two rivers.

Congress has to essentially authorize and appropriate funds for the Corps to do this.
