“Farmland across the Sacramento Valley sank rapidly as water was drained from underground aquifers during the historic 2020 drought, a new study found, a sign that the Central Valley’s water problems could be spreading north. Satellite observations over the Sacramento Valley detected ‘irreversible deformation’ from 2020 to 2022 due to increased groundwater pumping, according to research published in the Proceedings of the National Academy of Sciences on Monday. The study found that land did not rebound following the extreme drought years. The rapid and extensive land subsidence in the region pointed to a loss of storage capacity in the aquifer system, which researchers said poses ‘a serious threat to California’s water resources and infrastructure.'” (08/02/26)
