The model run results cover the period of October 13, through November 2, 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 will be closed October 28 through November 2, and are open during the remainder of the forecast period.  
3. The Middle River ag. Barrier is installed with all six flap-gates tidally operated.
4. The Old River at Tracy ag. barrier is installed with all 9 flap-gates tidally operated.
5. The Grant Line Canal ag. barrier is installed with all 6 culvert flap-gates tidally operated.
6. The Fall-Head of Old River barrier is installed with a notch and all 6 culvert slide-gates closed. 
7. The West False River drought barrier was officially breached on October 1, and the gradual removal is estimated to be completed by November 15. 
8.  Suisun Marsh salinity control flashboards are in and the three Suisun Marsh Salinity Control Gates are in tidal operation.
9.  San Joaquin River flow at Vernalis is at 470 cfs at the beginning of the forecast period and is anticipated to increase to 1,350 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 460 umhos/cm at the beginning of the forecast period to 210 umhos/cm by the end of forecast period.


With Transfers (Base Case, A) Assumptions

11.  Sacramento River flow at Freeport is at 7,532 cfs at the beginning of the forecast period and decreases to 5,205 cfs by the end of the forecast period.
12. CCFB intake decreases from 500 cfs at the beginning of the forecast period to 300 cfs by the end of the forecast period. 
13. Export at Jones Pumping Plant decreases from 1,600 cfs at the beginning of the forecast period to 1,200 cfs by the end of the forecast period. 

Without Transfers (B) Assumptions

11.  Sacramento River flow at Freeport is at 7,532 cfs at the beginning of the forecast period and decreases to 4,680 cfs by the end of the forecast period.
12. CCFB intake decreases from 370 cfs at the beginning of the forecast period to 300 cfs by the end of the forecast period. 
13. Export at Jones Pumping Plant decreases from 830 cfs at the beginning of the forecast period to 780 cfs by the end of the forecast period.
