Senator Roy Blunt of Missouri says if the Army Corps of Engineers doesn’t increase water flow from the upper Missouri River the next move may be to ask the president to step in.
The Corps began reducing the outflow from a dam in South Dakota on Friday.
That means less water for the already-low Mississippi River, which could lead to restrictions or even a halt on barge traffic by mid-December.
Senator Blunt says transportation down the river could be severely impacted if nothing is done.
