The CALFED Science Program was established to develop scientific information and synthesis for the state of scientific knowledge on issues critical for managing the Bay-Delta system. That body of knowledge must be unbiased, relevant, authoritative, integrated across state and federal agencies, and communicated to Bay-Delta decision-makers, agency managers, stakeholders, the scientific community, and the public. The Lead Scientist is responsible for leading, overseeing, and guiding the Science Program.

Science Program Vision Statement:

All Bay-Delta water and environmental policy is founded on the highest caliber science.

Science Program Mission Statement:

Our mission is to provide the best possible scientific information for water and environmental decision-making in the Bay-Delta system.

Science Program Strategic Objectives:

  • Support research. Initiate, evaluate and fund research that will fill critical gaps in our understanding of the current and changing Bay-Delta system;
  • Synthesize scientific information. Compile, analyze, and integrate scientific information across disciplines;
  • Facilitate independent peer review. Promote and provide independent, scientific peer review of processes, plans, programs and products;
  • Coordinate science. Coordinate with CALFED agencies to promote science-based adaptive management;
  • Communicate science. Interpret and communicate scientific information to policy-and decision-makers, scientists and the public.
