Central Valley groundwater pumping, land-sinking stressing Aqueduct. Is there a fix?
Years of collapsing areas of land in the San Joaquin Valley — caused primarily by the over-pumping of groundwater for farming — has taken a toll on California’s largest water delivery system that relies on stable land to work well. A state report released this year determined its 2023 annual water delivery capability had fallen 3% compared to original-design deliveries. If no action is taken, it could fall up to 87% by 2043. If that happens, 21 million Californians would feel the impacts, according to the California Department of Water Resources (DWR).
