Delta Science Fellows Program

2013 Delta Science Fellowships Awarded - The Delta Science Program in conjunction with California Sea Grant awarded Fellowships for 2013 to ten outstanding candidates – double the number that could have otherwise been awarded due to additional funding support from the U.S. Fish & Wildlife Service, NASA’s Jet Propulsion Laboratory, and the California Department of Water Resources.

Grants Program

The Delta Science Program has funded 40 research grants totaling more than $25 million. The Science Program considers funding scientific research to be a critical component in establishing unbiased and authoritative knowledge directly relevant to Bay-Delta actions. This knowledge will fundamentally advance the understanding of the complex environments and ecosystems within the Bay-Delta system to aid policy-makers, managers and other decision-makers.

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)
