Surface Water   Non-interactive line graphic




A network of stream gages record and telemeter river stage information. Flow measurements by field crews help calibrate and confirm calculations. Data from stream gage telemetry requires careful consideration as field conditions and equipment malfunctions can provide erroneous readings. A more accurate assessment of actual flow rates requires a review of the flow record and processing to account for actual conditions. This Quality Assurance Quality Control flow data is available on the Data Download page.

Non-interactive spacer  Flow Status

  • February 6, 2012: 12:00 noon: Combined Interim Flow and riparian diversion releases from Friant Dam increased to 350 cfs.
  • January 22, 2012, 9:00 pm: Combined Interim Flow and riparian diverter releases from Friant Dam increased to 285 cfs as operators were made aware that the powerplant issues were not fixed. 285 cfs is the maximum release from the two 18" valves at Friant Dam. Otherwise one large valve releases 460 cfs.
  • January 22, 2012, 3:00 pm: Combined Interim Flow and riparian diverter releases from Friant Dam decreased to 250 cfs in anticipation of the powerplant issues being fixed.
  • January 22, 2012, 8:00 am: Combined Interim Flow and riparian diverter releases from Friant Dam increased to 460 cfs to compensate for the previous evening's decrease.
  • January 21, 2012, 10:00 pm: Combined Interim Flow and riparian diverter releases from Friant Dam decreased to 195 cfs due to a power failure at the Friant Dam powerplant.

Interim Flow Constraints

  • Groundwater level threshold adjacent to the Eastside Bypass

Please see the Daily Evaluation of Flow and Seepage Constraints for more detailed daily updates regarding Seepage Hotline Calls and groundwater levels in priority wells.

Next Anticipated Flow Change

The next anticipated flow change is on February 6, 2012 to 350 cfs or more to release the quantity of water which would have been released in the absence of the Friant Dam powerplant power issue.

Please see the Flow Scheduling page for more information on how Friant and Mendota Dam releases are chosen.

Gaging Station Updates

  • The water level recorder cable in MW-09-89 rusted through and recorded a sudden drop in groundwater level on 10/27/2011. The cable was re-measured and adjusted on CDEC on 10/31/2011 at 15:00 hours.
