The Measure

The State Water Resources Control Board (SWRCB) adopts flow objectives that are necessary to achieve the coequal goals for the major tributary rivers to the Sacramento-San Joaquin Delta by June 2, 2018. 

Measure Details

In December 2018, the State Water Resources Control Board (SWRCB) adopted updates to the Bay-Delta Water Quality Control Plan to increase water flows through the Lower San Joaquin River and its tributaries—the Stanislaus, Tuolumne and Merced Rivers. In September 2019, SWRCB released a Draft of the initial biological goals for the Lower San Joaquin River.

In February 2020, the California Natural Resources Agency and the California Environmental Protection Agency released a framework for potential voluntary agreements to improve river flows and habitat to help recover salmon and other native fishes in the Sacramento-San Joaquin Delta. The framework is a milestone with ongoing discussions related to the Bay-Delta Water Quality Control Plan.

Delta Plan Strategy

Create More Natural Functional Flows

Delta Plan Recommendation

ER R1. Update Delta Flow Objectives. Development, implementation, and enforcement of new and updated flow objectives for the Delta and high-priority tributaries are key to the achievement of the coequal goals. The State Water Resources Control Board should update the Bay Delta Water Quality Control Plan objectives as follows:

(a) By June 2, 2014, adopt and implement updated flow objectives for the Delta that are necessary to achieve the coequal goals.

(b) By June 2, 2018, adopt, and as soon as reasonably possible, implement flow objectives for high-priority tributaries in the Delta watershed that are necessary to achieve the coequal goals.

Flow objectives could be implemented through several mechanisms including negotiation and settlement, Federal Energy Regulatory Commission relicensing, or adjudicative proceeding. Prior to the establishment of revised flow objectives, 100 percent of proposed actions that could significantly affect flow in the Sacramento-San Joaquin Delta are consistent with the existing Bay Delta Water Quality Control Plan objectives.
