Key Water Supply Assumptions
• Hydrology based on January 1 conditions• Operations to meet SWRCB WRD-1641• Use of current Reasonable and Prudent Alternatives of NMFS BiOp and FWS BiOp• Use of approximately 270 TAF of Rescheduled Project water in San Luis Reservoir• San Joaquin River flows/Mendota Pool operations not included in supply• Capacity for Joint Point of Diversion operations at Banks Pumping Plant is not available• Water supply augmentation actions are available

Key CVP Operations Points
• San Luis Reservoir fills in early February
• Jones Pumping Plant is at maximum capacity in July, August, and September
• Roe Island water quality is not triggered for February (x2)
