Due to the Lower Yuba River Accord transfer, we are estimating that about 60 TAF was or will be released from YCWA and about 48 TAF will be exported in the Delta (assuming a 20% loss). This water is for the Projects, so it reflects using each Projects’ facility, and does not go to any specific contractor, state or federal.  


The model run results cover the period of September 13, 2016 through October 3, 2016 and are based on the following assumptions:

Common Assumptions

1. CCFB Gates are operating to Priority 3 throughout the forecast period.
2. The Delta Cross Channel gates will remain open throughout the forecast period.
3.  Suisun Marsh salinity control flashboards are currently out; and the three Suisun Marsh Salinity Control Gates are in open position. However, the Flashboards are anticipated to be installed on September 26 and the gates are anticipated to remain open. 
4. The Middle River ag. barrier is installed with all 6 culvert flap-gates operating tidally. The barrier was raised 1 foot June 22. 
5. The Old River at Tracy ag. barrier is installed with all 9 culvert flap-gates operating tidally. 
6. The Grant Line Canal ag. barrier is fully installed with all 6 culvert flap-gates operating tidally. 
7. The Fall-Head of Old River barrier is anticipated to be installed with a notch and all 6 culvert slide-gates closed by October 1.
8.  San Joaquin River flow at Vernalis is at 330 cfs throughout the forecast period. 
9. San Joaquin River EC at Vernalis increases from 410 umhos/cm at the beginning of the forecast period to 590 umhos/cm by the end of forecast period.

With Transfers (Base Case, A) Assumptions

10.  Sacramento River flow at Freeport is at 17,469 cfs at the beginning of the forecast period and decreases to 14,600 cfs by the end of the forecast period.
11. CCFB is at 3,500 cfs at the beginning of the forecast period and increases to 5,000 cfs by the end of the forecast period. 
12. Export at Jones Pumping Plant is at 3,300 cfs at the beginning of the forecast period and increases to 4,200 cfs by the end of the forecast period. 
. 
Without Transfers (B) Assumptions

10.  Sacramento River flow at Freeport is at 16,909 cfs at the beginning of the forecast period and decreases to 14,600 cfs by the end of the forecast period.
11. CCFB is at 3,420 cfs at the beginning of the forecast period and increases to 5,000 cfs by the end of the forecast period. 
12. Export at Jones Pumping Plant is at 2,930 cfs at the beginning of the forecast period and increases to 4,200 cfs by the end of the forecast period.
