Call for Input: Winter-run Chinook Salmon Independent Peer Review
At the request of the U.S. Bureau of Reclamation and California Department of Water Resources, the Delta Science Program is facilitating an independent scientific peer review of the annual loss of Sacramento River winter-run Chinook salmon in water years 2024 and 2025.

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 one of the largest estuaries 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.
