Updates to the Delta Science Plan, May 9, 2016

The Delta Science Plan has been updated to reflect changes that have occurred since its release on December 30, 2013.


The updates include:

  • Modifying the title of the Science Steering Committee to the Science Advisory Committee
  • Updating the Advisory Committee’s charge (Appendix D)
  • Adding two appendices: K and L
    • Appendix K provides a well-defined methodology for a range of mechanisms to fund research including an outline of the proposal review process and estimated time frames for implementation
    • Appendix L describes the procedures addressing conflict of interest.
    • The objective of both appendices is to provide funding agencies with guidance in targeting the most optimum funding mechanism to support various research efforts.

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)
