WATER RESOURCES TECHNICAL REPORT−−In a normal year, all of the pumping demand in the PTP wells is replaced by waterdeliveries; and all of the pumping demand in the PVCWD wells is replaced by waterdeliveries except for PV-3, which is reduced by only 5 percent. The water deliverieson the PTP are from the Saticoy wellfield and amount to 1,600 AFY. The waterdeliveries to the PVCWD include 3,400 AFY supplied by the Saticoy wellfield and4,000 AFY supplied by the Conejo Creek Diversion.In a dry year, 29 percent of the pumping demand from the PTP wells, equallydistributed among the five wells, is reduced by water deliveries from the Saticoywellfield. This amounts to 1,000 AFY. In a dry year, all of the pumping demand inPV02 and PV-4 is reduced; and 89 percent of the pumping demand in PV-1 isreduced. Water deliveries from the Saticoy wellfield to PVCWD amount to1,000 AFY, and water deliveries from the Conejo Creek Diversion amount to4,000 AFY.Analysis shows that Scenario 3, which combines Saticoy wellfield and Conejo Creekdeliveries to offset PTP and PVCWD pumping, is the most effective in raising groundwaterelevations in the LAS in Pleasant Valley. This scenario will be used as part of the Base Casefor the GREAT Program groundwater flow modeling.W112003002SCO LW1458.DOC/ 033390002 72
