The Department of Water Resources (DWR) presented a detailed update on Central Valley land subsidence caused by groundwater pumping, which is reducing the California Aqueduct's capacity to move water south. Without corrective action, delivery reductions could range from 18% to 87% by 2043. The good news: DWR will begin the first of five interim repair projects in September 2026, starting with removal of a control structure at Check 17, followed by liner raises in pools 17 and 18. These interim actions are projected to reduce wet-year delivery losses to roughly 2% (compared to a potential 61% under a no-action scenario), buying time through approximately 2033 while long-term solutions are developed.
