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 attached model run results cover the period of September 22, through October 12, and are based on the following assumptions:

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 was installed with a notch and all 6 culvert slide-gates closed on September 14.
7. The West False River drought barrier was installed on May 28. 
8.  Suisun Marsh salinity control flashboards are installed and the three Suisun Marsh Salinity Control Gates are in tidal operation as of August 28, 2015.
9.  San Joaquin River flow at Vernalis is at 264 cfs at the beginning of the forecast period and is projected to stay at about 200 cfs through the forecast period.

12. CCFB intake increases from 300 cfs at the beginning of the forecast period to 800 cfs by the end of the forecast period. 
13. Export at Jones Pumping Plant increases from 800 cfs at the beginning of the forecast period to 1,400 cfs by the end of the forecast period. 


Without Transfers (B) Assumptions

11.  Sacramento River flow at Freeport is at 7,394 cfs at the beginning of the forecast period and decreases to 6,545 cfs by the end of the forecast period.
12. CCFB intake increases from 280 cfs at the beginning of the forecast period to 670 cfs by the end of the forecast period.
