The model run results cover the period of October 6, through October 26, and are based on the following assumptions:

Common Assumptions

1. CCFB Gates are operating to Priority 1 throughout 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 was installed with a notch and all 6 culvert slide-gates closed on September 14.
7. The West False River drought barrier was officially breached on October 1 and will gradually be removed through November 15. 
8.  Suisun Marsh salinity control flashboards are in and the three Suisun Marsh Salinity Control Gates are in tidal operation as of August 28.
9.  San Joaquin River flow at Vernalis is 355 cfs at the beginning of the forecast period and is anticipated to increase to 1,400 cfs by the end of the forecast period. The increase in flow is due to the fall pulse flow on the Stanislaus River as required by the NMFS Biological Opinion.
10. San Joaquin River EC at Vernalis is projected to decrease from 542 umhos/cm at the beginning of the forecast period to 172 umhos/cm by the end of forecast period.

12. CCFB intake remains at 800 cfs throughout the forecast period. 
13. Export at Jones Pumping Plant remains at 1,400 cfs throughout the forecast period.

Without Transfers (B) Assumptions

11.  Sacramento River flow at Freeport is at 7,488 cfs at the beginning of the forecast period. and decreases to 5,145 cfs by the end of the forecast period.
12. CCFB intake remains at 670 cfs throughout the forecast period. 
13. Export at Jones Pumping Plant remains at 875 cfs throughout the forecast period.
