Data & Alerts

Data & Alerts

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.
