Here's how to stop using all Colorado River basin water
Most of Glen Canyon's 3,000 miles of side canyons would be uncovered, and diverting water from Powell would send downstream the warmer water and higher flood flows that the Grand Canyon's ecosystem requires. (A way to move some of the sediment blocked by Glen Canyon Dam into the Grand Canyon would probably also be required to fully reverse the canyon's precipitous ecological decline.)
The long-term problems of the Colorado River basin are enormous, complex and politically fraught. But in the short and medium terms, the Bureau of Reclamation ought to take the immediate, reasonable, doable steps that would save water and begin the restoration of Glen Canyon and the Grand Canyon, nearly 400 miles of irreplaceable landscape at the heart of the Colorado Plateau.
