San Francisco Bay/Sacramento – San Joaquin Delta Estuary (Bay-Delta) Watershed Efforts


Save the Date! At the State Water Board meeting on June 7, 2023, the Board will hold an informational item regarding the potential addition of tribal beneficial uses to the Bay-Delta Plan.

Bay-Delta Plan Update and Implementation

Protecting the Bay-Delta watershed and its many beneficial uses is one of the State Water Board’s primary responsibilities and top priorities.  The State Water Board is responsible for adopting and updating the Water Quality Control Plan for the San Francisco Bay/Sacramento–San Joaquin Delta Estuary (Bay-Delta Plan), which establishes water quality control measures and flow requirements needed to provide reasonable protection of beneficial uses in the watershed. The State Water Board is now engaged in urgent efforts to address prolonged and precipitous declines of native aquatic species in the Bay-Delta and the ecosystem they depend upon.

The Bay-Delta Plan is being updated and implemented through separate processes (Plan amendments).

Related to the Bay-Delta Plan update and implementation process, the California Natural Resources Agency is currently engaged in an effort to develop proposed voluntary agreements with various water users in the watershed.   View information regarding the proposed voluntary agreements process.
