There was big, very big, ground water news for California in 2016, but almost no one paid attention because it came in the midst of the most heated presidential campaign in modern memory. For those who did notice, it seemed almost like Christmas came early, at midyear.

The news was this: A Stanford University study found huge and previously unknown supplies of ground water far beneath the surface of the ever-thirsty Central Valley. At a minimum, the newfound water supply amounts to twice the amount pumped from Central Valley aquifers since California was settled, or about 270 million acre-feet (one acre foot is the amount of water needed to cover an acre of land, weighing about 10 tons).
