Although recently folks in some parts of California have been measuring out lengths of gopherwood in cubits, the fact remains that the Sierras, which is the source of most of the state's water, is way low on snowpack; portending continuation of their lengthy drought. However, out there in the Mojave desert lies an extensive aquifer, down beneath the sands. So the plan is to pump 16.3 billion gallons of water a year to southern Orange County.
What could possibly go wrong?
It took several thousand years for that water to seep down from the surrounding mountains; might's well use it to fill swimming pools, no?
