Realtime Updates

  • 8/4/2016 – After a field investigation of groundwater conditions in the field near MW-49B, field groundwater levels are below the field threshold. In addition, the property is protected with an interceptor line. Restoration Flows resumed.
  • 7/28/2016 – MW-49B crossed the groundwater level threshold. Restoration Flows were stopped at Friant Dam.
  • 11/8/2012 – SJN – A continuous water temperature and specific conductance sonde was installed at the gage. real-time measurements are incorrect while installation quirks are fixed.
  • 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.

The Settlement identifies the releases of both Interim Flows and Restoration Flows. The Settlement stipulates the release of Interim Flows beginning October 1, 2009, and continuing until full Restoration Flows begin.
The purpose of the Interim Flows is to allow the Implementing Agencies to collect relevant data concerning flows, temperatures, fish needs, seepage losses, recirculation, recapture and reuse of flows.

 

Flow Scheduling

Forecasts  |  Allocations  |  Recommendations  |  Evaluations  |  Notifications

The release of water from Friant Dam for the SJRRP depends upon the amount of runoff. Using water supply forecasts for the Friant Division of the Central Valley Project, the SJRRP uses the estimated total unimpaired inflow below Friant Dam to determine an allocation. The Restoration Administrator makes recommendations on the timing of releases based on river conditions and the specific goals and objectives at that time. Prior to an increase in flow rates, the SJRRP analyzes the likely effects on the river and surrounding lands and documents the results with a Flow Bench Evaluation. Following an affirmative evaluation, the SJRRP issues a notification and changes the releases.

Snowpack
Exceedance forecasts use snowpack measurements to determine future runoff.

Water Supply Exceedance Forecasts  |  Top
Monthly water supply forecasts report unimpaired inflow values in terms of the percent exceedance, 10%, 50%, and 90%. The South Central California Area Office of Reclamation provides a best estimate for the purpose of developing delivery schedules. More information may be found here. Forecasts include:

SJRRP Allocations  |  Top
The SJRRP develops Default Flow Schedules for submittal to the Restoration Administrator to identify the annual allocation available. Allocations include:

Restoration Administrator Flow Recommendations  |  Top
The Restoration Administrator recommends a Flow Schedule to respond to current conditions and support data collection goals and objectives. Current RA Recommendations are available here.

Flow Bench Evaluations  |  Top
The SJRRP conducts Flow Bench Evaluations prior to deciding on an increase in flow target. These consider channel conveyance limitations, operations call concerns, seepage hotline concerns, real-time and manually measured groundwater levels and their relation to thresholds, as well as seepage predictions.

Daily Seepage Evaluations  |  Top
The SJRRP creates Daily Seepage Evaluations when flows are over 475 cfs in Reaches 2A and 3.

SJRRP Flow Change Notifications  |  Top
Prior to a significant change in flow target, the SJRRP issues a Flow Change Notification to a public distribution list. Examples are below.
