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.
Restoration Flows, water released from Friant Dam in accordance with the Settlement, are tracked downstream of Friant Dam at seven flow gauging stations within the Restoration Area (Friant Dam to the confluence with the Merced River), and at additional stations within the Lower San Joaquin River and Delta. Restoration Flows are parsed at these stations from other water which may be flowing in the San Joaquin River. Not all San Joaquin River flows are necessarily Restoration Flows, and in some cases Restoration Flows may not be present in sections of the San Joaquin River.
Restoration Flows may reduce as they travel downstream due to evapotranspiration, groundwater infiltration, or other natural causes. Restoration Flows may be recaptured (diverted from the river) to benefit the Water Management Goal when such recapture does not impact fish or water quality. Restoration Flows may not be diverted or used for any other purpose. Restoration Flows may not incorporate other tributary flows, accretions, or discharges as they travel downstream; Restoration Flows must originate from Friant Dam under the conditions of Reclamation’s water right.
Water volume is measured in acre-feet (AF). A flow rate of 1 cubic foot per second (cfs) for one day is equivalent to about 2 AF (more precisely 1.9835 AF).
