Scientific Peer Review

The Delta Science Program is a leading coordinator of independent scientific peer review in the Sacramento-San Joaquin Delta. The peer review process uses independent scientific experts and established guidelines to ensure credible and legitimate science can be used by water and environmental decision-makers. The Delta Independent Science Board also conducts science reviews that span the natural, physical, and social sciences.

Since 2010, the Delta Science Program has coordinated over 28 independent science reviews and science advisors. Reviews employ independent experts to evaluate completed processes, programs, plans, and products. Advisors typically give input on the development of processes, programs, plans, or products (e.g., Bay-Delta Plan Biological Goals Scientific Advisory Panel). Both reviews and advisors respond to a set of questions (a “Charge”) and write a report. Serial review types include Long-term Operations of the Biological Opinions (LOBO), Delta Regional Monitoring Program (Delta RMP), and WaterFix Aquatic Science.

Most recently, at the request of the Delta Stewardship Council’s Planning Division, the Delta Science Program convened a group of six independent scientific experts to review the proposed performance measures associated with the amendments to Chapter 4 of the Delta Plan.
