California’s Department of Water Resources has released its most comprehensive groundwater report to date. The Bulletin 118 Update 2025 covers groundwater conditions, use, and management across the state from 2020 to 2024, offering the most detailed assessment yet of a resource that supplies around 40% of California’s total water demand in average years. … Structured around four strategic themes: maximizing groundwater infrastructure for climate adaptation, accelerating SGMA implementation, strengthening equity for frontline communities, and improving data and monitoring tools, the report amounts to a call for California to move from reactive groundwater management to treating it as the cornerstone of its long-term water strategy.
