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.

Sacramento River Science Partnership A voluntary science enterprise established to inform joint learning on species recovery and water management on the mainstem of the Sacramento River Steelhead at Coleman National Fish Hatchery Near Ord Bend Side Channel Restoration Project Steelhead at Coleman National Fish Hatchery 1/19 Partnership Shares Science to Find Fish and Water Solutions

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.

Tal k Summary : From 2024 to 2026, seven unique spring pulse flow events were generated on the Sacramento River through increased releases from Keswick Reservoir, with the goal of boosting overall spring outmigration success for juvenile Chinook salmon (Oncorhynchus tshawytscha). Acoustic telemetry and rotary screw trap captures were used to measure pulse flow performance and indicated a gradient of success across the seven events. This gradient can provide insight into the elusive mechanistic underpinning of the flow-survival relationship, and thereby better inform pulse flow implementation in the future. 2026 Fall Annual Meeting Thursday, September 10, 2026 The Science of Salmonid Reintroduction Strategies for Central Valley Tributaries View the Presentations: 2026 Fall Annual Meeting Recording Floodplain Science Webinars September 30, 2026 Parentage Based Tagging on the Lower Snake Register HERE The meeting will feature the following speakers: Matthew Campbell, Idaho Fish and Game Rod Engle, US Fish and Wildlife Service Michael Herr, Washington Department of Fish and Wildlife Shawn Narum, Columbia River Inter-Tribal Fish Commission Chris Sullivan, Idaho Fish and Game Bill Young, Nez Perce Tribe Talk Summary: Presentations and a moderated panel on the use of parentage based tagging (PBT) in the Lower Snake River.

Parentage Based Tagging (PBT) The SRSP’s Science Subcommittee has been charged with hosting a series of science sharing presentations focused on parentage based tagging (PBT). The goals of these presentations include: Develop a shared understanding of PBT among a variety of audiences including scientists, field technicians, fishermen, water users, agency staff, and NGOs. Develop a shared understanding PBT as a tool that can be used to meet a range of objectives using lessons learned from other regions and applications.
