As the 2015-16 water year opened in October 2015, drought had driven the state’s reservoir and groundwater levels to all-time lows. Entire towns were left without water. Reports of lakes turned to puddles, of wells running dry by the thousands, and of the cracked ground above depleted aquifers sinking several feet a year dominated state headlines.
