The California State Water Resources Control Board heard an update on implementation of the Sustainable Groundwater Management Act, which requires local agencies to bring groundwater basins into balance by 2040 and 2042. … Since 2023, the California Department of Water Resources has determined that plans for seven basins were inadequate. In March 2023, it referred six basins to the state water board for intervention. The state water board may consider probation for the Delta-Mendota, Chowchilla and Pleasant Valley subbasins later this year. In his update to the board last week, Paul Gosselin, DWR deputy director for sustainable groundwater management, said the two drivers that led to the 2014 passage of SGMA were high rates of land subsidence and thousands of wells that went dry during the drought. He said subsidence remains a significant issue that affects infrastructure.
