SACRAMENTO, Calif. – The Bureau of Reclamation will hold its biennial science review on the biological opinions associated with the long-term operations of the Central Valley Project and State Water Project from Dec. 5 to Dec. 7, 2017, in Sacramento.

Reclamation, National Marine Fisheries Service and U.S. Fish and Wildlife Service use this biennial science review to examine prior year’s water operations and regulatory provisions prescribed by their respective Reasonable and Prudent Alternative (RPAs) actions. The goal is to develop lessons learned, incorporate new science, and make appropriate, scientifically justified adjustments to the implementation of the RPA actions and to better inform water operations in future years. The review also allows public input regarding the NMFS and USFWS Biological Opinion (BiOp) on the long-term operation of the CVP and SWP. The BiOps and their RPA actions were designed by NMFS and the USFWS to avoid the likelihood of jeopardy to listed species and adverse modification of critical habitat.

The California Department of Water Resources also participates in the review because it operates the SWP. The Delta Stewardship Council will host the meeting and assist in facilitation.
