California EcoRestore is a multi-agency initiative led by the California Natural Resources Agency. The California Department of Water Resources (DWR) is a partner on 28 of the 30 projects which seek to restore at least 30,000 acres of Sacramento-San Joaquin Delta (Delta) habitat by 2020.

EcoRestore projects are driven by world-class science and guided by adaptive management and seek to support the long-term health of the Delta and its native fish and wildlife species.

The types of habitat targeted include tidal wetlands, floodplain, upland, riparian, fish passage improvements and others. Specifically the program aims to achieve the following:
