FWIW——— Lake Powell is about 1500 miles from the Mississippi.
That’s just under twice the length of the Trans-Alaska Pipeline System (800 miles). That was built in 1975-1977.
A minor detail. Every person driving from the Midwest to Arizona can take a 5 gallon tank of river water with them, but only if they are driving an electric vehicle to avoid negatively effecting the climate.
And then, after climbing about 3,500 feet in elevation, they can empty the bucket into Lake Powell.
The aqueduct idea is crazy, since it requires an enormous amount of energy to lift the water from the level of the Mississippi to the level of Lake Powell.
Only been out West twice, but seems like it was uphill all the way. Would be hard to pump water up there.
