From what I can tell, the only way to really restore the natural flow of the river is to stop (and reverse) channelizing the river, allow flooding to happen seasonally, and re-engineer riverine communities and agricultural uses accordingly. Also, not sucking underground aquifers dry and instead only tap them to the degree they recharge. When we suck them up faster than they recharge, we're stealing water from our kids, and I reckon it's better for us and them if we just adapt by using surface water, such as the river, or even desalinating the gulf water, and living within our means as far as natural ecosystems and geological systems go.

Dear @valued-customer !
I remember Oregon being 1800 miles from the Mississippi River, so I'm surprised you're worried about the Mississippi River!😃
I wonder what your relationship is with the Mississippi River!

I'm looking at a map of the United States showing the distance between you and the Mississippi River! I'm truly overwhelmed by the vastness of the American continent!

I live in a small country, so it's hard for me to understand the thoughts of people who live in a vast continent like you!

My guess is that you're claiming that if the aquifers of the North American continent dry up, the American ecosystem will be destroyed!
I agree with you, because the Mississippi River has been severely damaged for corporate profits for a long time!

I believe that if American companies restore the damaged ecosystem of the Mississippi River, the problem you are worried about will be solved!

My respected elder bro, @valued-customer !
I have a hard time guessing your thoughts, which are as vast as the North American continent!😆

I can only understand that you love America very much!

I hope your health and long life!
