Objectives Disclose and discuss ongoing and planned monitoring, biological and physical modeling, and analysis and synthesis related to voluntary species recovery and water management goals. Disclose and discuss priorities for reducing uncertainty regarding the conditions necessary to achieve desired fishery and water management goals by developing and applying one or more conceptual models linking actions to expected outcomes to provide for transparency in the scientific basis for decision making and priorities. Identify and pursue opportunities to consolidate the number of collaborative forums addressing fishery needs in the upper Sacramento River watershed and support a regional structured decision-making process (that includes structured decision-making under the Central Valley Project Improvement Act). Coordinate a Science and Monitoring Plan for the upper Sacramento River that is integrated with other science and monitoring efforts addressing Central Valley salmon stocks. Develop and undertake experimental actions to test hypotheses and address shared priority management questions. Facilitate and establish protocols for collaboration among the scientific and stakeholder community for the discussion of findings, prior to publication, and the shared synthesis of new science into decision support models. Identify and understand the trade-offs of decisions between different species and water uses.

The meeting will feature the following speakers: Peter Goodwin, University of Maryland Center for Environmental Sciences (emeritus), Chair Erin N. Bray, San Francisco State University Rene Henery, Trout Unlimited Jay R. Lund, University of California, Davis (emeritus) Steven Sadro, Tahoe Environmental Research Center and University of California, Davis Patrick J. Sullivan, Cornell University (emeritus) About the Webinar During the webinar, the speakers will address: NAS recommendations for cold water pool management at Shasta Reservoir  The weight of the evidence supporting the mechanistic relationships between cold water pool management and benefits to the Sacramento River fisheries, and in particular, winter- and fall-run Chinook.  Outstanding areas of scientific uncertainty that could be reduced to improve decision making.   Sacramento River Science Partnership Annual Meeting Condition and Survival of Outmigrating Juvenile Salmonids in the Sacramento River February 6, 2026: In-Person Meeting SRSP Workshop Agenda: View the 2025 Annual Meeting Presentations Recording: SRSP 2025 Annual Meeting - YouTube 2026 Annual Fish Trends Meeting Wednesday, April 1, 2026 2026 Fish Trends Webinar Video
