Admin Measure Summary
Prior to the establishment of revised flow objectives, 100 percent of proposed actions that could significantly affect flow in the Sacramento-San Joaquin Delta should be consistent with the existing Bay Delta Water Quality Control Plan objectives.
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.
