Sept. 5 - Exploring Abandoned Derelict Vessels in the Sacramento-San Joaquin Delta

Annie Daly will discuss how abandoned derelict vessels (ADVs) in the Sacramento-San Joaquin Delta impede navigation, interfere with boating traffic, and leak toxic chemicals into waterways. She has worked with the Delta Protection Commission and CDFW’s Office of Spill Prevention and Response and will present her research that examined aerial and on-water survey data, costs for vessel removal, and how other states handle ADVs. This information will help managers anticipate the resources needed to address the problem.

Council Appoints Dr. John Callaway as New Lead Scientist

Dr. John Callaway, an internationally recognized expert in wetland restoration, specifically wetland plant ecology and sediment dynamics, was unanimously appointed by the Council as Lead Scientist at the July 2017 meeting. Most recently, Dr. Callaway has served as the director of the Master’s Program in Environmental Management at the University of San Francisco. “I look forward to the continuing efforts of building a collaborative scientific community with its search for common truths on the many critical issues that face the Delta,” Dr. Callaway said. “The development of One Delta-One Science is clearly a project of critical importance to California that is helping set standards of how the best available science can more effectively inform the making of policy.”

The New Issue of SFEWS: Volume 15, Issue 2

Volume 15, Issue 2 of the free SFEWS online journal discusses the varying perspectives that emerge as one follows the downstream movement of river water through the Delta and into San Francisco Bay. But, is the water considered wasted if it's allowed to enter the ocean? And when discussing the population of certain bellwether fish species in the Delta, the word "exection" is sometimes included and can cause debate. In this edition the concept is addressed and is considered not inevitable in the short run, if the most current scientific understanding to manage the ecosystem is utilized and if bold steps towards recovery are initiated.

The Delta
The State of Bay-Delta Science 2016 Interactive Website

The State of Bay-Delta Science is a collection of papers that represents a synthesis of the current scientific understanding of the Sacramento-San Joaquin Delta. Together the papers emphasize the progress made on key research questions during the past decade and identify remaining knowledge gaps. The new interactive SBDS webpage offers more depth and clarity of the materials. All six of the related seminars by the report’s contributors are available for viewing. Finally, a Summary-of-Policies document distills key findings from SBDS 2016 for a policymaker audience.

Eight Early-Career Scientists Named Delta Science Fellows

The Delta Stewardship Council’s Delta Science Program has named eight doctoral graduate students and post-doctoral researchers as recipients of the agency’s 2017 Delta Science Fellowship.The Fellowship Program, administered by California Sea Grant, pairs junior scientists with academic and community mentors to work on collaborative data analysis and research projects as guided by the Delta Science Plan. Additional financial commitment is provided by the State and Federal Contractors Water Agency and the U.S. Bureau of Reclamation. 


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)
