As part of the San Joaquin River Restoration Program, the physical and biological effects of flows are monitored along the San Joaquin River from Friant Dam to the confluence of the Merced River. An Annual Technical Report documents the monitoring program and provides results from prior releases on a regular schedule. Making decisions on release requires information prior to the compilation and release of the Annual Technical Report. The following pages provide the data to support operations for the SJRRP.
Monitoring and Analysis Plan
The Monitoring and Analysis Plan (MAP), formerly known as the Agency Plan, describes upcoming monitoring and analysis to manage Interim and Restoration Flows for the next year of the San Joaquin River Restoration Program.
Data Reporting
Agencies are conducting studies to support the San Joaquin River Restoration Program. Current and previous year’s studies and their status are updated biannually.
Flow Schedule
The Flow Schedule section describes the process for how Interim Flows are determined, scheduled, evaluated and released. This section also includes links to recent documents created through this process. The process of scheduling flows is documented in the Restoration Flow Guidelines.
See Flow Schedule for:
- Interim Flow Status, Constraints, and anticipated flow changes
- Snowpack
- Water Supply Forecasts
- SJRRP Allocations and Default Flow Schedules
- RA Recommendations
- Flow Bench Evaluations
- Daily Seepage Evaluations
- Flow Change Public Notifications
Surface Water
The Surface Water section contains recent data used to determine flow rates at specific flow compliance locations that may assist in determining short-term changes in releases.
See Surface Water for:
- Tracking the River’s End
- Stream Gage Telemetry – CDEC Stations
- Flow Measurements and Shift Corrections
Groundwater
Groundwater data located here helps determine allowable releases.
See Groundwater for:
- Real-time Wells
- Weekly Groundwater Reports
- Well Atlas
Subsidence
Subsidence data located here helps in design of projects.
Water Quality
Water Quality data collected in this section helps to determine recommended future releases during Restoration Flows.
Fisheries
Monitoring of habitat conditions provides information for potential project needs and future flows.
