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.

Louise Conrad
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.

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.

Delta Independent Science Board (Delta ISB) Teleconference on August 10 in Sacramento

On August 10, 2018, the Delta ISB will discuss the draft prospectus for its ecosystems review, and the status of other reviews.

Delta Independent Science Board (Delta ISB) Meeting on July 12 in Sacramento

On July 12, 2018, the Delta ISB will discuss the status of current reviews and will consider finalizing the summary sheet for its habitat restoration review. Outside of the usual business matters, the Delta ISB will moderate a panel discussion with monitoring programs that collect data at a national or regional scale that includes the Bay-Delta to help inform the review on the Delta Monitoring Enterprise.

A Beginner’s Guide to the Sacramento-San Joaquin Delta

Created by State Fellow Heidi Williams, this guide is as a resource to learn more about this integral place in California. It begins with the basics of what the Delta is, where it is, and why it’s important; followed sections on its history, its people, and the animals and plants as well as some of the environmental challenges and how agencies and managers are trying to manage them.


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)
