Overdraft is especially severe in the southern parts of the Central Valley, where groundwater levels have reached more than 33 meters below previous historic lows (CDWR, 2014). Overdraft has resulted in saltwater intrusion and other water quality impacts, significant land subsidence, lost water storage, and increased energy costs, among other adverse impacts. In response to worsening groundwater conditions, the state recently passed the Sustainable Groundwater Management Act of 2014 (SGMA). The act provides a framework for local authorities to manage groundwater supplies but allows for state intervention if necessary to protect groundwater resources.
