The "Mission for My Vision" is not total natural re-population: It's education and
some success. I believe the main part of the creek would need to be re-routed from the ramp with re-enforced artificial pools due to erosion. Some years would be better concerning different species; including forage.
It wouldn't be easy but that's not my problem as I'm the Ruler of North Dakota.
I'd need advised on the current conditions and most viable crop: Water in the observation areas would maintain proper depth and presentation IAW my and ACOE guidelines on average. My minion lawyers would persuade ACOE to adjust/suggest flow with minimal interference. ND would have it's creek and ACOE can "float the boat" from there. Main point is observation at various pools. We would need them constantly full for tours. Another problem is oxygen. Land owners and golf courses in Dixie install fountains. I believe temp is fine as long as the creek is supplied from the lake bottom. This creek could become another matter of state pride and provide much opportunity for research and thesis.
IMHO, there wouldn't be much conflict with our creek and barge traffic.
