I grew up out there in the 1950s and recall constant threats of drought. When the Mormons settled in Utah, Salt Lake was totally barren but was transformed into a lush landscape through damning and irrigation. Pretty much the same thing for California's Central Valley. Of course, the massive immigration and urbanization of the region has put tremendous pressure on the aquifers.
LIFE IS CONSTANTLY CHALLENGING.
