Now Available: The 2025 State of Bay-Delta Science - Part 1
Part 1 of the 2025 State of Bay-Delta Science is now available online in the San Francisco Estuary and Watershed Science (SFEWS) journal’s latest issue. In whole, this edition includes seven articles summarizing the state of the science on climate change and extreme events, social and ecological impacts, and climate governance and adaptation strategies in the Bay-Delta and its watershed. Articles will be released across multiple issues of SFEWS in 2025. Part 1 includes four articles: an introduction to the edition written by the editorial board, and three focused review articles covering climate governance, droughts, and heatwaves.
New Ecosystem-Related Regulations for Prioritizing Restoration in California’s Delta
The Delta Stewardship Council has completed the Administrative Procedure Act process to amend the California Code of Regulations, title 23, sections 5001 through 5015, and add section 5005.1, Appendix 3A, Appendix 4A, and Appendix 8A. The changes implement policies established in the 2022 amendment to the Delta Plan Chapter 4: Protect, Restore, and Enhance the Delta Ecosystem.
New Blog - More to Explore: Enhancing Recreation in California’s Delta
The Delta Stewardship Council is pleased to share a new blog highlighting the development of a new state park in the Sacramento-San Joaquin Delta. The blog was co-written by Council Chair Julie Lee, Special Assistant for Planning & Science Amanda Bohl, and Executive Fellow Audrey Cho. It focuses on recreation, a key topic of the upcoming Delta Plan Interagency Implementation Committee spring gathering.

The 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 Section 85054)

California relies on the Delta.

The Sacramento-San Joaquin Delta is part of the largest estuary on the west coast of North and South America. It supplies a portion of the water used by two-thirds of Californians; that’s more than 27 million people.

We align Delta decision-making
with science.

In the face of climate change, this connection is more important than ever. Progress requires bringing the right people together to implement timely, science-based solutions.

A resilient statewide water supply and ecosystem necessitate collective implementation of the Delta Plan.

The Delta Plan creates a common vision for taking-on current and predicted challenges. It includes regulations, non-regulatory recommendations, and performance measures to further water supply reliability, ecosystem resiliency, and the unique values of the Delta as a place.

We are a partner; engage with us.

We fund scientific research; invest in the next generation of scientists and policymakers; coordinate independent scientific peer reviews; synthesize relevant data; facilitate science communication; and identify tools for adaptive management.
