The natural aquifer beneath the desert floor is replenished with water from the Colorado River. That doesn't mean we're free to waste any water, but things here aren't as severe as in the rest of the state. Californians are great at banding together to pull through a bad situation. The drought is super-serious but we've had water shortages before and the state will have them again.
Sorry to Dean for taking his post way, way off track. I need a slap.
