Both the DWR and Reclamation are involved in moving third party water from the north to the south for each Project’s contractors.  DWR is looking at moving water during the summer period.  The USBR is looking at moving water later (Sept – Nov).  Transfers will come from Sellers on the Yuba, Bear, American and the Feather for the SWP; and Yuba and Sacramento for the CVP.  The total volume moving across the Delta can be around 200 TAF (+/-).



The model run results cover the period of July 21, through August 10, and are based on the following assumptions:

Common Assumptions

1. CCFB Gates are operating to Priority 1 as of May 1.
2. The Delta Cross Channel gates had been open since June 26, however they were closed on July 20 and will reopen again on July 24.The gates are anticipated to remain open throughout the remainder of the forecast period.  
3. The Middle River ag. barrier was installed on March 31, with all 6 culvert flap-gates tied open. As of April 3, all six flap-gates are being tidally operated, and barrier was raised one foot on June 4. 
4. The Old River at Tracy ag. barrier was installed on April 3, with all 9 flap-gates tidally operated. 
5. The Grant Line Canal ag. barrier was partially installed on April 17, with all 6 culvert flap-gates tied open. The barrier was fully closed with all 6 culvert flap-gates tidally operating beginning on June 18.
6. The West False River drought barrier was installed on May 28. 
7.  The three Suisun Marsh salinity control gates tidal operation was changed to open position, the flashboards were removed, and the boat lock was closed on June 2. 
8.  San Joaquin River flow at Vernalis is at 149 cfs at the beginning of the forecast period and is projected to stay at about 120 cfs through the forecast period.  
9. San Joaquin River EC at Vernalis is projected to increase from 615 umhos/cm at the beginning of the forecast period to 750 umhos/cm by the end of forecast period.

With Transfers (Base Case, A) Assumptions

11.  Sacramento River flow at Freeport is at 7,573 cfs at the beginning of the forecast period and decreases to 7,034 cfs by the end of the forecast period.
12. CCFB intake is zero for the first two days due to outage, and increases to 500 cfs for the remainder of the forecast period.
10. Export at Jones Pumping Plant is at 300 cfs through July, and increases to 700 cfs for the remainder of the forecast period.

Without Transfers (B) Assumptions

11.  Sacramento River flow at Freeport is at 7,573 cfs at the beginning of the forecast period and decreases to 6,380 cfs by the end of the forecast period.
12. CCFB intake is zero for the first two days due to outage, increases to 200 cfs during July, and increases to 390 cfs for the remainder of the forecast period.
10. Export at Jones Pumping Plant is at 300 cfs through July, and decreases to 290 cfs for the remainder of the forecast period.
