It’s been a good winter for drought-stricken California. Record-breaking precipitation in January has raised reservoir levels and added to the essential Sierra Nevada snowpack. It will take many years of consistent, above-average rainfall to fully recover from the drought, and that seems unlikely given the variable nature of the state’s climate. California’s water problems are not only the result of historically scant rainfall. Convoluted water policies, patchwork regulations and burdensome water politics perpetuate the problems, causing imbalances in the way water is managed.
