Bay-Delta Program & Delta Watermaster Portals

San Francisco Bay/Sacramento-San Joaquin Delta Estuary (Bay-Delta) Program

The San Francisco Bay/Sacramento-San Joaquin Delta Estuary (Bay-Delta) includes the Sacramento-San Joaquin Delta, Suisun Marsh, and San Francisco Bay. California’s two major rivers, the Sacramento and the San Joaquin, converge in the Delta and meet incoming seawater from the Pacific Ocean in San Francisco Bay. Water diversions from the Delta supply a portion of the drinking water to over two thirds of Californians and for millions of acres of farmland.

The State Water Board’s Bay-Delta Program facilitates the development and review of plans and policies to protect beneficial uses of the San Francisco Bay/Sacramento-San Joaquin Delta Estuary (Bay-Delta) pursuant to the California Water Code and federal Clean Water Act. The Bay-Delta Program also facilitates water right activities related to the Bay-Delta, including implementation of the Bay-Delta Water Quality Control Plan through water right requirements.
