Water Quality Control Plan for the San Francisco Bay/Sacramento-San Joaquin Delta Watershed (Draft)

California State Water Resources Control Board (SWRCB) | August 19th, 2026


A water quality control plan consists of: (1) beneficial uses to be protected; (2) water quality objectives for the reasonable protection of beneficial uses; and (3) a program of implementation for achieving the water quality objectives. This Plan establishes water quality objectives for which implementation can be accomplished by assigning responsibility to water right holders and water users to mitigate for the effects on the designated beneficial uses of their diversions and use of water. Together, the beneficial uses and the water quality objectives established to reasonably protect the beneficial uses are called water quality standards under the terminology of the federal Clean Water Act.
