>The droughts in SoCal are going to keep making these traditional fresh water sources you mention even more scarce.
What's going on in California is nothing out of the ordinary. California is and always was a desert - and building a city the size of Los Angeles there would never have worked had it not been for importing huge amounts of water from central CA (see: Mona Lake) or the Colorado River.
Actually most of the Colorado river water goes for agriculture at 1930's water rates that are utterly insanely undervalued - but that's a whole other topic :p
