The Delta Science Program is leading the five-year review and update of the Delta Science Plan and requests input from the public and Delta science community regarding updates to the content of the document. Join us as we discuss the direction of the updated Science Plan and how you can contribute to its implementation.
On March 9, 2018, the Delta Independent Science Board (Delta ISB) will meet to discuss the status of addressing public comments on its draft water quality review, public comments received on its water supply reliability review draft prospectus, and the status of upcoming requests for review from the Delta Stewardship Council and the Delta Science Program.
The 2017 Long-term Operations Biological Opinions (LOBO) Science Review report synthesizing the findings of the independent review panel is now available online. An independent science panel reviewed the implementation of actions required by the Endangered Species Act for salmon, steelhead, green sturgeon, and Delta smelt to operate the State and Federal Water Projects.
The Delta Independent Science Board (Delta ISB) will meet to discuss the status of current reviews, and will address written public comments received on the draft prospectus for the review on the Interagency Ecological Program (IEP) and the draft review on water quality science. In addition, the Delta ISB will finalize its summary sheet for its final review on the Delta as an Evolving Place.
On Dec. 11, the Delta Independent Science Board (Delta ISB) will meet to discuss the water quality thematic review and to receive public feedback on its latest draft for this review. In addition, the Delta ISB will discuss the status of the summary sheets for various completed Delta ISB reviews, the status of the programmatic review on the Interagency Ecological Program (IEP), and the status of other thematic reviews on monitoring, water supply reliability, and ecosystems.
An independent science panel will conduct a science review of the implementation of actions required by the Endangered Species Act related to salmon, steelhead, green sturgeon, and Delta smelt for operations of the State/Federal Water Projects.
The Delta Independent Science Board (Delta ISB) will undertake a broad review of monitoring efforts in the Delta. This Monitoring Enterprise Review will investigate numerous programs across the natural, biological, and social sciences. This Brown Bag series is intended to cover the state of monitoring in the Delta as seen from a wide range of perspectives. Extended discussions with the Delta ISB, invited guests, and attendees will follow each seminar for 60 to 90 minutes. Each seminar will be webcast.
On Nov. 17, the Delta Independent Science Board (Delta ISB) will review the latest public discussion draft of the water quality thematic review and will decide whether to release this version for a 30-day comment period. The Delta ISB will also discuss the status of developing one-page summary sheets for its review, and the status of current reviews on the Delta Monitoring Enterprise, the Interagency Ecological Program, ecosystems, and water supply reliability. At 1:00 p.m. the Delta ISB will listen to a brown bag seminar by Dr. Stacy Sherman of the CA Dept. of Fish and Wildlife to help inform the Delta ISB’s review on the Delta Monitoring Enterprise.
The panel evaluated the analytical tools developed for comparing the range of proposed alternatives for the Yolo Bypass Fish Passage and Habitat Restoration Program Environmental Impact Statement/Environmental Impact Report and Biological Assessment. The intent of the independent scientific peer review was to ensure the new analytical tools and their associated assumptions are being appropriately used, that the best available science was utilized, and ensure results are appropriately interpreted for evaluating the design alternatives.
The Sacramento Regional County Sanitation District is building new facilities at its Wastewater Treatment Plant.These upgrades will dramatically reduce total nitrogen levels and alter the concentrations of different forms of nitrogen in the Sacramento River. To understand what effects these changes may have on the Delta ecosystem, a baseline needs to be established. Operation Baseline is a set of pilot studies funded by the Council to fulfill this need. The studies will assess the current state of nutrients, aquatic vegetation, and the food web in areas that may be affected by the changes in nutrient loading, and they will lay the groundwork to enable comparisons between present and future conditions.
The Sept. 2017 issue of ESTUARY News includes articles on exploring the Delta's heritage, Bay Area water districts crafting drought contigency plans, and how a 25-year old program could be a beacon of environmental protection. To help keep you up-to-date on what’s happening throughout the estuary, the Council helps sponsor this quarterly publication of the San Francisco Estuary Partnership.

On October 19, the Delta Independent Science Board (Delta ISB) will discuss progress on current reviews on water quality and monitoring, the status of the one-page summary sheet for the Delta ISB’s adaptive management review, and the status of planning for reviews on the Interagency Ecological Program (IEP), water supply reliability, and ecosystems.
At its core the Science Action Agenda (SAA) is a four-year science agenda for the Sacramento-San Joaquin Delta that prioritizes and aligns science actions to inform management decisions, fill gaps in knowledge, promote collaborative science, build the science infrastructure, and achieve the objectives of the Delta Science Plan.The new interactive SAA webpage offers more depth and clarity of the materials. All five of the thematic science action areas are listed, offering easy access to the 13 priority science actions and associated management needs listed in the document.

Volume 15, Issue 3 of the free SFEWS online journal discusses the various projects and programs underway to enhance and preserve the Delta as an estuary, as well as the aquatic and terrestrial life that call the region home. Included are discussions about a monitoring network that provides quantitative information on the status of imperiled species at key life stages and geographic locations over time; large scale restoration of habitats requiring significant changes in waterways and land uses but fail to account for human uses that can lead to less public support for the restoration efforts; and restoration activities that are underway to recover a rockweed that was injured during the Cosco Busan oil spill in November 2007.
On Sept. 14, the Delta Independent Science Board (Delta ISB) will finalize its review of the Delta Plan Amendment for Conveyance, Storage Systems, and the Operation of Both (CSO). The Delta ISB will also discuss its current reviews, how to distribute one-page summaries for its reviews, and ideas for the next thematic reviews. Then, on Sept. 15, Cliff Feldheim, Chief of DWR’s Suisun Marsh Program, and Steve Chappell, Ex. Dir. of the Suisun Resource Conservation Dist., will lead a field tour in Suisun Marsh. On Sept. 14, Mr. Feldheim will provide an overview of the monitoring, research and restoration in Suisun Marsh. The public may join the field tour. However, transportation and lunch will not be provided.
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)
