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 September 1, through September 21, and are based on the following assumptions:

Common Assumptions

1. CCFB Gates are operating to Priority 2 on September 1, and then change back to Priority 1 for the remainder of the forecast period.
2. The Delta Cross Channel gates are open throughout the forecast period.  
3. The Middle River ag. barrier was installed on March 31, 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, as of June 18 the barrier was fully closed with all 6 culvert flap-gates tidally operating.
6. The Fall-Head of Old River barrier is anticipated to be installed by September 15.
7. The West False River drought barrier was installed on May 28. 
8.  The three Suisun Marsh salinity control gates position was changed from open to tidal operation, the flashboards were installed, and the boat lock was opened as of August 28. 
9.  San Joaquin River flow at Vernalis is at 190 cfs at the beginning of the forecast period and is projected to stay at about 120 cfs through the forecast period.  
10. San Joaquin River EC at Vernalis is projected to increase from 365 umhos/cm at the beginning of the forecast period to 625 umhos/cm by the end of forecast period.


With Transfers (Base Case, A) Assumptions

11.  Sacramento River flow at Freeport is at 8,600 cfs at the beginning of the forecast period and increases to 8,880 cfs by the end of the forecast period.
12. CCFB intake decreases from 2,495 cfs at the beginning of the forecast period to 1,800 cfs by the end of the forecast period. 
13. Export at Jones Pumping Plant increases from 980 cfs at the beginning of the forecast period to 1,800 cfs by the end of the forecast period. 

Without Transfers (B) Assumptions

11.  Sacramento River flow at Freeport is at 8,600 cfs at the beginning of the forecast period and decreases to 6,975 cfs by the end of the forecast period.
12. CCFB intake decreases from 2,465 cfs at the beginning of the forecast period to 1,770 cfs by the end of the forecast period. 
13. Export at Jones Pumping Plant increases from zero cfs at the beginning of the forecast period to 300 cfs by the end of the forecast period.
