There's an abundance of freshwater in the east coast, northwest and midwest. Why not shift some of the exess water from the great lakes, east coast and northwest to southwest? Can't we pipeline the water to giant reservoirs in the sw or even carve extend tributaries from the missouri river or create canals down to the sw? It's not exactly rocket science.

Way, way too expensive. Pumping water east of the Rockies would use a ton power. Local desalination would cost way less. This plan is not feasible because it pumps water from Sea of Cortez to Salton Sea over 200 mi.
