The model run results cover the period of August 11, through August 31, and are based on the following assumptions:

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 (+/-).

Common Assumptions

1. CCFB Gates are operating to Priority 1 as of May 1.
2. The Delta Cross Channel gates were opened on June 26, however they have since been closed during several periods for water quality purposes. The gates were recently closed on August 11, will reopen on August 14, and 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. It is anticipated that the flashboards will be installed, the gates will be in tidal operation, and the boat lock will be open as early as August 28. 
8.  San Joaquin River flow at Vernalis is at 172 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 620 umhos/cm at the beginning of the forecast period to 800 umhos/cm by the end of forecast period.

With Transfers (Base Case, A) Assumptions

10.  Sacramento River flow at Freeport is at 7,500 cfs at the beginning of the forecast period and increases to 7,820 cfs by the end of the forecast period.
11. CCFB intake increases from 500 cfs at the beginning of the forecast period to 800 cfs by the end of the forecast period. About 40 cfs of CCFB allotment is for a CVP transfer that will be delivered to Byron Bethany out of CCFB.
12. Export at Jones Pumping Plant increases from 700 cfs at the beginning of the forecast period to 800 cfs by the end of the forecast period. 

Without Transfers (B) Assumptions

10.  Sacramento River flow at Freeport is at 7,500 cfs at the beginning of the forecast period and decreases to 7,180 cfs by the end of the forecast period.
11. CCFB intake increases from 390 cfs at the beginning of the forecast period to 690 cfs by the end of the forecast period. 
12. Export at Jones Pumping Plant increases from 290 cfs at the beginning of the forecast period to 390 cfs by the end of the forecast period.
