Publicly accessible, web-based query and reporting system of historical and current fish, environmental, and hydrologic information, vital to year-round planning and adaptive management of the Central Valley Project and State Water Project. Data uploads provide the most up-to-date data as it is made available, whether it be daily, biweekly, monthly or annually. Basic conditions, performance measures, and threshold-based alerts are available through data aggregation and analysis of environmental conditions.
Customized data visualizations, biological thresholds, and data tables of current conditions with recent and real-time data to facilitate in-season monitoring and management by Central Valley Workgroups and Monitoring Teams.
Interactive models for prediction of egg survival and fry emergence; juvenile migration and survival; delta migration, routing, and survival; and loss and salvage. Includes Shiny apps developed by SacPAS in support model exploration and implementation of 3rd party tools.
Access all queries and modeling tools available on SacPAS by topic or theme. Topics include species, salmon life stage, and groupings of environmental data. Themes include Track-a-Cohort, Shiny apps, and maps.

Survival estimates are calculated by summarizing the detection history of study populations, and assuming a fish has died when it is not detected by subsequent downstream receivers. We used a CJS survival model in RMark to estimate reach specific (survival per 10 river kilometers) and cumulative (from release location to last downstream detection) survival rates. We used a simple survival model (survival and detection efficiency is a function of time) to derive these estimates. For each survival tab, a map is displayed with all receiver locations used to generate survival for each population, and a figure and table displays the estimates and associated error. The unique number of fish detected at each receiver location is also provided.
