1. Groundwater Sustainability Plan Update Coming for Board Adoption in December 2026 The SGA is updating its Groundwater Sustainability Plan (GSP) as required every five years under the Sustainable Groundwater Management Act (SGMA). Staff described the changes as "evolutionary, not revolutionary," with updates to sustainable management criteria, monitoring networks, water budgets, and how interconnected surface water is addressed. The public release of the draft is targeted for August 20, 2026, with a detailed presentation planned for the next October board meeting and a formal adoption vote at the December meeting. Stakeholders should pay close attention, as the updated sustainable management criteria redefine acceptable groundwater levels for all beneficial users — including ag users and domestic well owners.
