Sacramento River Science Partnership Annual Workshop Thursday, October 26, 2023 9:00 am – 4:15 pm Lake Natoma Inn, Folsom CA Registration closes on October 20, 2023 Register Here! Sacramento River S cience Partnership (SRSP) is excited to announce its 2023 Fall Workshop. We hope you will be able to join us in person, though there will also be a virtual option. Registration closes - Friday 10/20/2023 Cost of ticket includes lunch, snack, and coffee Objectives Share information on water management based on ever changing hydrology, with outcomes and lessons learned from Victoria, Australia for application to California’s conditions. Share understanding of potential application of the Victorian Objectives to the Central Valley.

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.

Research Priorities The Sacramento River Science Partnership Charter includes the following research priorities: Understanding temperature tolerances and other conditions necessary for salmonid egg incubation and early life stages. Understanding non-temperature sources of mortality including, pathogens, predation, lack of suitable spawning habitat, and redd de-watering, among others. Understanding conditions necessary for juvenile spring-run survival. Assessing the quantity, condition and habitat needs of emerging juvenile fry and smolts, including synthesizing information from existing monitoring and advances in genetics and otolith research, and exploring management relevance. Developing decision support tools for species recovery including physical and biological modeling and exploring integration with management questions including understanding effects between species. Understanding research needs associated with reintroductions of winter run Chinook Salmon. Understanding the fishery needs within the Sacramento Mainstem with a focus on salmonids and concern for other species of interest as well. Understanding key physical and engineering constraints associated with operations and diversions.
