A reasonable agricultural solution is to stop growing food in California. There are many fewer farms in the eastern part of the country than there once were because the settlement of California, fossil fertility, underground fossil water, and federally-subsidized surface water projects made agriculture in California dirt cheap. That put the east coast growers out of business. The eastern USA of course has undergone a huge multi-century boom and bust cycle, being naturally forested, then significantly cleared for European-style agriculture, and now again highly forested. If we just grew food where the water is, we wouldn't be having so much fuss over agriculture in the desert.
