In an announcement made Monday, the agency said that the goal is to restore the canals’ carrying capacity. Portions of the California Aqueduct, San Luis Canal, Delta-Mendota Canal, and Friant-Kern Canal can’t convey as much water as they used to because of land subsidence.

The four canals collectively deliver water to more than 29 million people, 2.9 million acres of farmland, and 130,000 acres of wetlands. The completed projects will restore up to 50% of the capacity of the canals over the next 10 years, DWR said.
