Delta Science Fellows Program

The goal of the Delta Science Fellows Program is to bring together junior scientists with Delta agency scientists and senior research mentors to work collaboratively on data analysis and research projects relevant to Delta policy and management.


Since 2003, the Delta Science Fellows Program has paired pre-doctoral students and post-graduate researchers with Bay-Delta agency scientists and senior research mentors in order to address high priority science actions important to managing the Bay-Delta system.


Including the Class of 2016, the Delta Science Program and recent partners (U.S. Fish and Wildlife Service [USFWS], NASA Jet Propulsion Laboratory [JPL], National Oceanic and Atmospheric Administration National Marine Fisheries Service Southwest Fisheries Science Center [NOAA NMFS SWFSC], and State and Federal Contractors Water Agency [SFWCA]) have funded 78 Fellows, totaling over $10 million dollars.


The goal of funding this research is to invest in knowledge that will advance the understanding of the complex environments and systems within the Bay-Delta to aid policymakers and managers, and to train the next generation of research scientists for water issues in California.


The deadline for applications for the 2017 Science Fellowship Program was September 23, 2016. Click here for more information.

The 2016 Fellows Program

The Delta Science Program and funding partners NOAA NMFS and SFCWA, in conjunction with the California Sea Grant, awarded 12 Fellowships to outstanding candidates to pursue research on a variety of topics relevant to the Sacramento-San Joaquin Delta. Fellowships were awarded based on the intellectual merit of the application and its expected contribution to the high impact science actions. These included:


  1. Assessing the effects of drought on the Delta
  2. Effectiveness and implications of habitat restoration actions
  3. Develop decision support tools for management of estuarine and migratory species
  4. Science supporting the enhancement and protection of the cultural, recreational, natural resource, and agricultural values of the Delta


A total of $1,580,561 was awarded to the following 12 recipients:

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)
