SacPAS: Central Valley Prediction and Assessment of Salmon through Ecological Data and Modeling for In-Season Management

Mission: Provide web-based services to link data and science to in-season management.

This website will provide monitoring, evaluation, and web-based data products and services for primary and associated activities funded by the U.S. Bureau of Reclamation (USBR) and mandated by the Endangered Species Act (ESA). It will serve as a means by which information integration services can be provided to the Central Valley Project Improvement Act (CVPIA) and ESA participants. Web-based services will relate fish passage to environmental conditions and provide resources for evaluating the effects of river management and environmental conditions on salmon passage and survival.

Data Queries & Alerts

Provide a 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 will 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.

Fish Model

Adapt a smolt passage model based on NOAA’s Comprehensive Passage (COMPASS) Model to characterize movement of water and juvenile fish through the Sacramento River system to the head of the San Francisco Bay Delta. The model uses available data from long-term monitoring sites. Physical data may include water velocity, temperature, and flow. SacPAS Fish Model User's Manual.

Annual update of CDFW GrandTab California Central Valley Chinook Population Database report uploaded to SacPAS database. 8 May 2018.
Egg Kill version of SacPAS: Spawning to Emergence, Fish Model
The SacPAS fish modeling process begins with egg deposition at the time of spawning. Development rate and survival can be modeled by various methods to determine fry emergence from the gravel. On this page you can control temperature inputs, redd counts/timing/location and survival details for egg development modeling. This is model is in testing phase. 14 March 2018.
