San Luis Obispo County officials adopted a management plan for a portion of the county’s groundwater Tuesday. It’s a plan required under California’s 2014 Sustainable Groundwater Management Act—or SGMA—a law that, for the first time in California’s history, placed rules on the use of groundwater, which supplies up to two-thirds of the state’s fresh water. The Paso Robles subbasin is one of the state’s most depleted underground water sources, after decades of overuse and mismanagement.
