Who We Are Formed in 2018, to establish and maintain a science enterprise for voluntary collaborative research, modeling, monitoring, and synthesis relevant to salmonid and other in-river species recovery and water management on the main stem Sacramento River to facilitate joint learning and fact-finding between and among scientists and managers.

Join Us There are several opportunities to collaborate with the Partnership. Attend science-sharing events , including quarterly science webinars and annual science workshops. Visit the Events page for more information on recent and upcoming events. Participate in an ad-hoc group. The Partnership occasionally forms small groups to help with tasks such as planning science-sharing events or developing science activities. Become a member. Membership is open to those who meet the following eligibility criteria: Are resource agencies, NGOs, coalitions of constituents of the Sacramento River, academic research institutions. Membership will not include private consultants and private organizations. Manage or work on issues related to the Sacramento River and its fisheries and water management. Represent a credible voice in the Sacramento River community of resource managers and scientists. Sign the SRSP Charter. Commit to participate in Partnership and Science Subcommittee meetings and ad-hoc groups as appropriate. If you are interested in engaging with us or becoming a member, please email info@sacriverscience.org .

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.
