Drought is a tricky thing to define. It is not just a matter of how little water falls out of the sky. If it were, you would be forgiven for believing that California’s wettish winter had ended, or even alleviated, the worst drought in state history. But no. Despite the snow in the Sierra Nevada, the water filling Lake Shasta, and the rapids in the Kern River, California is still in a state of drought. For now, maybe forever.
