This alert provides an overview of the ongoing implementation of the Sustainable Groundwater Management Act (SGMA). It details the status of Groundwater Sustainability Plans (GSPs), recent and pending actions by the State Water Resources Control Board (SWRCB or State Board) concerning probationary designations, developments regarding fee and reporting exclusions, SGMA-related litigation, and pertinent legislative activity. … The outcomes of current and future probationary proceedings, particularly for critically overdrafted basins, alongside the results of pending litigation, will have far-reaching implications for groundwater management across California. The SWRCB’s upcoming decision regarding the Chowchilla Subbasin may offer a precedent for other basins that demonstrate substantial GSP improvements and proactive engagement.
