Hey BH, I think you might have read too deeply into my post.
I do fully understand the U.S. Army Corps of Engineers has a larger mandate than commercial navigation maintenance. And, I do understand that many other "management" activities would continue. I did not communicate that all the rest of the mantenance activities would go away if commercial navigation ended on the lower Missouri River. And I certainly didn't suggest to "magically throw the river back to pre-European state."
My primary point was, some USACE "management" activites would not be necessary if commercial navigation ended. The level of those terminated activities would have to be determined, but it would save tax dollars and reduce strain on limited resources that aren't balanced by the economic contribution by the Missouri River barge industry, and allow them be be redirected to USACE activties that should be of a higher priority.
Wouldn't it be logical to take any of the resources gained and apply them to the disasterous state of the U.S.'s levee system, which the USACE helps maintain. In Sacramento, we are just a small earthquake away from a levee disaster that will make the infrastructure failure in New Orleans look like a water-main break (that's not hyperbole). Dallas' levees have been assessed as deficient, which currently holds back waters from a significant portion of the downtown area. Nearly 30% of all levees in the South are deemed deficient and 59% of all levees in the West are also deemed deficient by the U.S. Army Corp of Engineers. This post-Katrina assessment by the USACE will cause FEMA to redraw the flood maps within the next two years and cause billions of dollars worth of property and industry to be uninsurable if they are behind a levee deemed deficient.
By way of disclosure, I work for an infrastructure engineering firm that works closely with the USACE, but we're trying very hard to educate Americans and lawmakers of the serious threat the deficient levee system poses.
I've attached an interesting fact sheet my department put together and a link to a webpage we've created to provide some education and information about the risk our country faces due to this serious levee problem. Some really good links on the right side of that page.

I contend that some resources can be reallocated to higher-priority needs if commercial navigation on the lower Missouri River were allowed to end.
