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 20, 2016 through October 10, 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; however they are anticipated to be installed on September 27. The three Suisun Marsh Salinity Control Gates are currently in open position and are anticipated to remain open once the flashboards are installed. 
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 15,139 cfs at the beginning of the forecast period and decreases to 11,900 cfs by the end of the forecast period.
11. CCFB is at 5,500 cfs at the beginning of the forecast period and decreases to 3,500 cfs by the end of the forecast period. 
12. Export at Jones Pumping Plant is at 3,940 cfs at the beginning of the forecast period and decreases to 3,300 cfs by the end of the forecast period. 
. 
Without Transfers (B) Assumptions

10.  Sacramento River flow at Freeport is at 14,530 cfs at the beginning of the forecast period and decreases to 11,900 cfs by the end of the forecast period.
11. CCFB is at 5,420 cfs at the beginning of the forecast period and decreases to 3,500 cfs by the end of the forecast period. 
12. Export at Jones Pumping Plant is at 3,540 cfs at the beginning of the forecast period and decreases to 3,300 cfs by the end of the forecast period.
