California WaterFix Aquatic Science Peer Review Phase 2A and 2B Reports

At the request of NOAA’s National Marine Fisheries Service (NMFS), the U.S. Fish and Wildlife Services (FWS), and the CA Dept. of Fish and Wildlife, select staff from the Council’s Delta Science Program convened Phases 2A and 2B of the CA WaterFix (CWF) Aquatic Science Review. Phase 2A reviewed the 2081(b) Incidental Take Permit application analyses and draft Adaptive Management Framework for CWF. Phase 2B reviewed sections of the NMFS’ and FWS’ draft Biological Opinions and a proposed approach to establishing Longfin Smelt outflow criteria for the 2081(b) Incidental Take Permit analyses for CWF. The peer review reports for both Phases 2A and 2B have been completed.

Presented by the Delta Stewardship Council and the U.S. Geological Survey, the Seminars allow the Candidates to showcase their presentations. Each talk will take place from noon to 1 at the Park Tower Plaza, 980 Ninth St., 2nd Floor Conference Center in Sacramento. These seminars are free, open to the public, and will shown via WebEx.

Delta Independent Science Board (Delta ISB) To Meet February 16 in Sacramento

On Feburary 16, 2017, the Delta Independent Science Board (Delta ISB) will finalize its review of the State Water Resources Control Board’s working draft Scientific Basis Report for Phase 2 of the Bay-Delta Water Quality Control Plan. The Delta ISB will prepare for its review of the California WaterFix Final EIR/S and hear updates on its thematic reviews.

Free Joint Symposium: Contaminants in the San Francisco Bay-Delta: Novel Tools and Approaches to Evaluate Effects of Multiple Stressors

This day-long symposium on Jan. 31 will provide an overview of the impacts of multiple stressors on aquatic ecosystems, emphasizing novel tools and approaches developed for toxicological studies. Speakers will be presenting on the current state of research, latest technologies, and implications for management decisions. It's free and open to the public.

California WaterFix Aquatic Science Peer Review

Phase 2B of the independent scientific peer review for sections of the NMFS’ and FWS’ Biological Opinions and a proposed approach to establishing Longfin Smelt outflow criteria will take place January 23-24, 2017.

The New Issue of SFEWS Offers the Final State of Bay-Delta Science 2016 Reports

Volume 14, Issue 4 of the free SFEWS online journal examines the latest scientific information about the recent advances in understanding flow dynamics and the transport of water-quailty constituents in the Delta, an overview of multi-dimentional models of the Delta, and factors and processes affecting Delta levee system vulnerability. The issue also includes papers on nutrient dynamics of the Delta, contaminant effects on Delta species and human health, and perspectives on Bay-Delta science and policy. These articles and others form the chapters of the Council's State of Bay-Delta Science 2016.

Jan. 12 Brown Bag – Flow Dynamics and Transport of Water-Quality Constituents in the Sacramento–San Joaquin River Delta

Over the past decade considerable advances have occurred in the understanding of flow dynamics and how water-quality elements move within the Bay-Delta. Dr. Schoellhamer will discuss these advances focusing on five specific topics. His recent report on this issue will be included in The State of Bay-Delta Science (SBDS) 2016. This Brown Bag seminar is one of a series showcasing the State of Bay-Delta Science 2016.

Delta Independent Science Board (Delta ISB) To Meet January 12-13 in Sacramento

On Jan. 12 the Delta Independent Science Board will discuss its review of the State Water Resources Control Board’s working draft Scientific Basis Report for Phase 2 of the Bay-Delta Water Quality Control Plan update. Action on this item will be taken on Jan. 13. Also on Jan. 13, other current and upcoming review efforts will be discussed, including a briefing on a draft Delta Plan performance measures amendment. Both days of the meeting will be webcast.

Independent Peer Review of SacWAM is Now Online

SacWAM is a hydrology/system operations model developed by the Stockholm Environment Institute and the State Water Resources Control Board to assess potential revisions to instream flow and other requirements in the 2006 Water Quality Control Plan for the San Francisco Bay/Sacramento-San Joaquin Delta Estuary. It was developed using the Water Evaluation And Planning system, and is intended to be user-friendly and to easily accept various scenarios. The Delta Science Program conducted an independent peer review of SacWAM to assure transparency and confirm its robustness for applications related to updates of the Bay-Delta Plan, and as part of its mission to provide the best possible unbiased scientific information to inform water and environmental decision-making in the Bay-Delta.

Delta Independent Science Board (Delta ISB) To Meet Dec. 8 in Sacramento

The Delta Independent Science Board will discuss and review two sets of comments. The first is to the State Water Resources Control Board staff about the working draft Scientific Basis Report prepared to support the Phase II updates of the Bay-Delta Water Quality Control Plan, and the second is a comment letter to the organizers of the 2016 Bay-Delta Science Conference.

2016 Long-term Operations Biological Opinions Information & Update

The purpose of the 2016 information and update is to provide stakeholders and members of the public a forum in which to provide input regarding the NOAA’s National Marine Fisheries Service’s and the US Fish and Wildlife Service’s Biological Opinion on the long-term operations of the Central Valley Project and State Water Project. Specifically, there will be an opportunity for input regarding the various regulatory actions prescribed by their respective Reasonable and Prudent Alternatives. The review will enable NMFS and USFWS to use lessons learned, incorporate new science, and make appropriate, scientifically justified adjustments to the implementation of the RPAs.

Dec. 6 Brown Bag – Food Webs of the Delta, Suisun Bay, and Suisun Marsh

Restoration efforts that benefit native ecosystems in the Delta require an in-depth understanding of food webs. Dr. Larry Brown, a research biologist with the U.S. Geological Survey, will discuss these issues while reviewing the current understanding of food webs in the Delta. He will draw from his report that's included in The State of Bay-Delta Science (SBDS) 2016. This Brown Bag seminar is part of a series showcasing the State of Bay-Delta Science 2016.

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)
