The Delta
The State of Bay-Delta Science 2016 Interactive Website

The State of Bay-Delta Science is a collection of papers that represents a synthesis of the current scientific understanding of the Sacramento-San Joaquin Delta. Together the papers emphasize the progress made on key research questions during the past decade and identify remaining knowledge gaps. The new interactive SBDS webpage offers more depth and clarity of the materials. All six of the related seminars by the report’s contributors are available for viewing. Finally, a Summary-of-Policies document distills key findings from SBDS 2016 for a policymaker audience.

Delta Independent Science Board (Delta ISB) To Meet May 11-12 in Walnut Grove

On the morning of May 11 the Delta ISB will take a half-day field tour of the Lindsey Slough Restoration Project and the Jepson Prairie Preserve. The members will then meet to finalize their reviews of the Draft 2017-2021 Science Action Agenda and the EcoRestore Adaptive Management Program White Paper. The Board will also discuss its review of CaliforniaWaterFix Final EIR/S, hear updates on its thematic reviews of Water Quality and Comprehensive Assessment of Monitoring, and hear a presentation on the State of the Bay-Delta Science (SBDS) 2016 Retrospective. The Delta ISB will also hold an evening community meeting on May 11 seeking dialogue and input from Delta residents, and initiate an outreach of its Delta as an Evolving Place report.

Eight Early-Career Scientists Named Delta Science Fellows

The Delta Stewardship Council’s Delta Science Program has named eight doctoral graduate students and post-doctoral researchers as recipients of the agency’s 2017 Delta Science Fellowship.The Fellowship Program, administered by California Sea Grant, pairs junior scientists with academic and community mentors to work on collaborative data analysis and research projects as guided by the Delta Science Plan. Additional financial commitment is provided by the State and Federal Contractors Water Agency and the U.S. Bureau of Reclamation. 

Your Comments are Requested on the Draft Science Action Agenda by May 31, 2017

The Delta Science Program is seeking public comment on the Draft 2017-2021 Science Action Agenda, a four-year science agenda for the Delta, developed through an open process working closely with the broad Delta science and management community. The comment period has been extended to May 31, 2017. Please click here for more information.

Delta Independent Science Board (Delta ISB) To Meet April 13 in Sacramento

On April 13, 2017, The Delta Independent Science Board (Delta ISB) will take action on the Delta as an Evolving Place final draft. The Delta ISB will discuss its review comments on the EcoRestore Adaptive Management Program White Paper, and on the California WaterFix Final EIR/S, and initiate a review of the Draft 2017-2021 Science Action Agenda.

The New Issue of SFEWS: A Central Valley Joint Venture Special Issue

Volume 15, Issue 1 of the free SFEWS online journal addresses the challenges of setting conservation objectives for birds in the Central Valley. Despite massive losses of habitat, the Central Valley’s wetlands, riparian forests, and grassland–oak savannah woodlands still provide some of the most important bird habitat in North America. Nearly three million ducks, two million geese, and 350,000 shorebirds continue to overwinter in this region, making the Central Valley an internationally important area for migratory waterbirds in the Pacific Flyway. Prioritization of conservation actions in that region for these waterbirds and landbirds is a critical step toward increasing their populations.

March 21 Brown Bag – Constructed Wetlands as a Sustainable Approach for Treating Emerging Organic Chemicals of Concern

Dr. Cooper’s research interests include sunlight-mediated photochemical reactions in natural waters and free radical chemistry of aqueous solutions. Recently, he has been involved in the application of ozonation for ballast water. This Brown Bag seminar is one of a series showcasing the work of candidates for the Delta Lead Scientist position.

California WaterFix Aquatic Science Peer Review Phase 2A and 2B Reports

At the request of NOAA’s National Marine Fisheries Service (NMFS), the U.S. Fish and Wildlife Services (FWS), and the CA Dept. of Fish and Wildlife, select staff from the Council’s Delta Science Program convened Phases 2A and 2B of the CA WaterFix (CWF) Aquatic Science Review. Phase 2A reviewed the 2081(b) Incidental Take Permit application analyses and draft Adaptive Management Framework for CWF. Phase 2B reviewed sections of the NMFS’ and FWS’ draft Biological Opinions and a proposed approach to establishing Longfin Smelt outflow criteria for the 2081(b) Incidental Take Permit analyses for CWF. The peer review reports for both Phases 2A and 2B have been completed.

March 20 Brown Bag – Understanding Mud and Carbon in the San Francisco Bay Wetlands, Insights for Incorporating Science into Management

Dr. Callaway’s expertise is in wetland restoration, specifically wetland plant ecology and sediment dynamics. His recent research projects focus on the development of restored wetlands, including evaluations of the importance of plant species diversity and the role of physical heterogeneity in the development of ecosystem functions. This Brown Bag seminar is one of a series showcasing the work of candidates for the Delta Lead Scientist position.

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)
