re: Mississippi River diverging: When do we finally let it go down the Atchafalaya?

only way to really save the coast from shrinking is to let the river do what it wants, as nature intended.

This won't happen just because the flow has shifted to where it naturally wants to be. The Atchafalya is currently building marsh in two places, the main delta and the Wax Delta diversion off of it. The Mississippi also builds wetland on its current state. Seasonal flooding (sheet flow in this case) would be needed to have effects away from the deltas. So...they need to let the rivers flood annually.

Not to mention, less sediment is making it down stream due to dams upstream on Mississippi river tributaries. So...let's blow those all up too.
