Now Available: Delta Conservation Adaptive Management Action Strategy

The Delta Science Program and the Interagency Adaptive Management Integration Team have released a near-term adaptive management strategy that aims to integrate existing resources and cut across individual agency missions to support adaptive management efforts in the Sacramento-San Joaquin Delta. The strategy is based on the Delta Plan’s Adaptive Management Framework and presents a series of actions to support adaptive management of conservation activities in the Delta.

New Brown Bag Seminar Series: Integrating the Bay and Delta

There has been an ongoing conversation about the importance of thinking about the San Francisco Estuary holistically as a connected system, rather than siloing the Bay, Delta, and watersheds. While there are governance barriers to managing the system as one, scientifically speaking it is important not to ignore the influence they have on each other. The purpose of this brown bag series is to contribute to the conversation about Bay-Delta linkages. Ongoing management efforts focused on water quality issues will be used as a way to explore the challenges and benefits related to thinking of the system as one.

State, Federal Agencies Fund Nearly $10 Million in New Delta Science Studies

The Delta Stewardship Council and the U.S. Bureau of Reclamation are pleased to award nearly $10 million to fund 15 critical scientific studies in the Sacramento-San Joaquin River Delta and Suisun Marsh over the next three years. Projects went through a rigorous and competitive selection process of multiple reviews, including a panel of nationally renowned subject matter experts. Projects were chosen based on scientific rigor and their potential to fulfill knowledge gaps and needs identified by the 2017-2021 Science Action Agenda.

Now Available: San Francisco Estuary and Watershed Science Volume 17, Issue 1

The latest issue of San Francisco Estuary and Watershed Science (SFEWS) features a piece on the diet of Largemouth Bass co-authored by Delta Stewardship Council Deputy Executive Officer of Science Louise Conrad. Understanding the ecology of this top predator is crucial to understanding how the species potentially affects the Delta's fish community.

Meet the Interagency Ecological Program Lead Scientist: Steve Culberson

Housed within the Delta Stewardship Council, Interagency Ecological Program (IEP) Lead Scientist Steve Culberson regularly works with the Delta Science Program to identify, track, and explain the status and needs of Bay-Delta science. Co-localizing the IEP lead scientist within the Delta Stewardship Council allows for stronger collaboration and communication between data collectors and data users while working towards the vision of One Delta, One Science.

Council Announces Louise Conrad as Deputy Executive Officer for Science

Conrad comes to the Delta Science Program from the California Department of Water Resources, where she served as a program manager for estuarine science and synthesis. In this role, she focused on applied science to understand major stressors to the Delta in support of management efforts, including the California Natural Resources Agency’s Delta Smelt Resiliency Strategy. She also led a multi-agency group of scientists for the Interagency Ecological Program to conduct ecological synthesis on topics ranging from invasive species to drought.

Now Available: Meeting Notice for March 4 Bay-Delta Plan Biological Goals Scientific Advisory Panel

Formed at the request of the State Water Resources Control Board and facilitated by the Delta Science Program, this advisory panel will present its draft recommendations during a public meeting on March 4, 2019. These recommendations are for developing scientifically defensible methods for formulating biological goals that can be used to assess progress toward achieving the Bay-Delta Plan’s narrative objectives.

One Delta, One Science

‘One Delta, One Science’ refers to an open Delta science community that works together to build a common body of scientific knowledge. This open science community will have the capacity to adapt and inform future water, societal, and environmental decisions across multiple organizations and programs. One Delta, One Science will accelerate the discovery of facts and innovation within the open science community by exploring genuine differences in scientific opinion and addressing them in a transparent manner.

A Delta Stewardship Council Blog

Written monthly, this blog intends to foster discussion around important Bay-Delta questions. The first post was co-written by Executive Officer Jessica Pearson and Lead Scientist John Callaway after a discussion series hosted by the Council during its summer 2018 meetings that focused on using data to drive decision-making and science governance.


McCormack Williamson Tract and Operation Baseline Projects: Delta Science Program Informational Meeting - February 7, 2019

The Delta Science Program is pleased to present an informational meeting with two critical science initiatives in the Bay-Delta: Operation Baseline and the McCormack Williamson Tract Project. These studies explore how physical habitat features and changes to them affect the food web and ecological processes.

62 Applications Received for Delta Science Proposal Solicitation

The California Department of Fish and Wildlife and the Delta Science Program, with support from the U.S. Bureau of Reclamation, received 62 applications for the Delta Science Proposal Solicitation. Common themes among the applications addressed monitoring, data management, and modeling, as well as interactions between stressors, managed species, and communities. Proposals were due by 4:00 PM PDT on October 26, 2018.

Delta Science Plan Workshop

Draft Delta Science Plan Update

Per the Delta Science Program's request, the draft updated Delta Science Plan is undergoing review by the Delta Independent Science Board (Delta ISB). The draft updated Delta Science Plan, a framework to guide collaborative approaches to develop and communicate shared scientific knowledge that informs policy, management, and the public, resulting in effective action in the Delta.

Final Delta ISB Water Quality Review Now Available

The Delta Independent Science Board (Delta ISB) has finished its review of the scientific basis for assessing water quality in the Delta. This review focuses on contaminants and nutrients in the Delta, and on how findings about them have been sometimes used and sometimes neglected in decisions related to ecosystem health. With the completion of this review, the Delta ISB is committed to undertake an active outreach effort to engage the community about the findings and recommendations from this review.


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)
