Background

NOAA’s National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlife Service (USFWS) have each issued a Biological Opinion (BiOp) on the long-term operations of the Central Valley Project (CVP) and State Water Project (SWP) that include Reasonable and Prudent Alternatives (RPA) designed to alleviate jeopardy to listed species and adverse modification of critical habitat.

 

Up until 2016, NMFS’ RPA required the U.S. Bureau of Reclamation (Reclamation) and NMFS to host a science review no later than November 30 of each year to determine whether the implementation of any measures prescribed in the RPA should be altered in light of information learned from the prior year’s operations or research. Under direction from the Secretaries of Commerce and Interior, this review was expanded to include a review of the implementation of the USFWS Long-term Operations BiOp. The California Department of Water Resources (DWR) also participates in the review because it operates the SWP. The intent of the review is to inform NMFS and USFWS as to the efficacy of the prior years’ water operations and regulatory actions prescribed by their respective RPAs, with the goal of developing lessons learned, incorporating new science, and proposing scientifically justified adjustments to the implementation of the RPAs to support decision-making for future water years.

 

In April 2016, Reclamation and NMFS agreed to temporarily modify the RPA science review frequency from annual to biennial from 2016 through 2020. At that time, Reclamation and NMFS will evaluate whether to make this change permanent or consider additional changes. The next science review will be held in November/December 2019. For more details, please see the agency correspondence (above).

Coequal goals

The Delta Stewardship Council was created in legislation to achieve the state mandated coequal goals for the Delta. "'Coequal goals' means the two goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the Delta ecosystem. The coequal goals shall be achieved in a manner that protects and enhances the unique cultural, recreational, natural resource, and agricultural values of the Delta as an evolving place." (CA Water Code §85054)
