I struggle with doing this under the guise of turning it back to it’s “natural” state. That ship sailed when the built the locks in 1963 and unless you continue to remove them downstream the river will never be natural again.
I agree with Dutch that this will take years to sort out if it ever does get done. But, the only part of the river that will be close to “natural” will be from Coon Rapids to St Paul. If LD 3 is used to keep a navigation channel open through St Paul to the MN River you only get a handful of miles that are natural. Do they go so far as to remove all of the wing dams, too?
I’m not sure how I feel about all of this because there are more questions than answers at this point.
