Department of Water Resources
Under SGMA, the Department of Water Resources is charged with developing regulations for revising groundwater basin boundaries and for evaluating and implementing Groundwater Sustainability Plans (GSPs) and coordination agreements; identifying basins subject to critical conditions of overdraft; identifying water available for groundwater replenishment; and publishing best management practices for the sustainable management of groundwater.
