You want to pump water over the Continental Divide?
Or drop a pipe into a nice, big, high altitude lake, Yellowstone 7700 so pumping is not an issue, siphoning will work just fine, run the pipe down Jackson Hole, across Wyoming into a tributary of the Colorado river.
Just ignore that volcano under the lake
It can be done using the power from gas that is currently being burned off to power the pumps. But it will never be allowed by the EPA.
