As water officials repair damage from subsidence, they demand prevention from groundwater agencies
State water officials have asked local groundwater agencies to better prevent land subsidence. Simultaneously, the state is also working to fix the damage caused by sinking land. … The sinking of land is slowly impairing the complex system of canals that deliver water throughout the state. According to a 2017 report by the Department of Water Resources (DWR), the sinking and buckling of portions of the California Aqueduct, which runs 444 miles from the Sacramento-San Joaquin Delta to the Tehachapi Mountains, has reduced its flow capacity and its ability to store water in overflow pools.
