    Delta Salmon Rearing Project

    Lead San Francisco Estuary Institute [SFEI]
    Description This project summarizes existing research and knowledge around suitable rearing habitat for Chinook salmon in the Sacramento-San Joaquin Delta;identifies areas of suitability for rearing salmon using a combined suitability analysis of four mapped habitat parameters;and provides recommendations for types of restoration needed to improve or restore rearing habitat, as well as to identify where in the Delta these restoration efforts could be prioritized.

    A Next-generation Model of Juvenile Salmon Migration through the Sacramento-San Joaquin Delta

    Lead University of California - Santa Cruz [UCSC]
    Description While migrating through the Delta and its tributaries, Chinook salmon and steelhead move through diverse habitats, encounter predators, interact with highly dynamic flows, and are impacted by a multitude of human-made structures. Funding for this Project will be use to develop integrated system-level models that will effectively manage salmonid populations and other key resources in the California Central Valley.

    Enhanced Acoustic Tagging, Analysis, and Real-Time Monitoring

    Lead National Oceanic and Atmospheric Administration [NOAA]
    Description Description This project tracks the movement and survival of wild and hatchery juvenile Chinook salmon with a large acoustic receiver network (JSATS), including real-time receivers, and the development of real-time metrics and retrospective modeling of juvenile salmon migration data. Need There is a well-documented need for improved detection and associated modeling of salmon migration and survival in the Central Valley. Understanding salmon survival and movement dynamics in the Delta and its tributaries is critical to the operation of state and federal water projects, recovery of ESA-listed species, and sport and commercial fisheries management. Objectives • Maintain 20 real-time JSATS receivers: will provide information on migrating salmon smolt location and timing of Delta entry and exist, which is key for informing time-sensitive decisions • Deployment of autonomous JSATS receiver array: this will provide fine-scale reach-specific survival and movement rates • Development of new metrics for the real-time data: this will inform key management relevant questions, such how many fish are entrained at critical junctions • Development of real-time website to convey movement and survival rates of acoustic tagged juvenile salmonids at various real-time locations in the Sacramento River and Delta.
