Would entail purchasing water from an upstream reservoir for release to the Colorado River when the Cameo call (or some other senior mainstem right) is preventing RG from storing, thus allowing more storage in RG. Limited to replacing deliveries to the pump canal service area (PCSAI preaently furnished by diversions from E. Rifle Creek via Harvey Gap Res. In dry years, a majority of the water supply for the PCSA is pumped. Therefore, this option may only be useable in average or wet years. If water pumped during these years could be carried over, this could help in future dry years. Not effective. Pumping cost estimated at $12/al not including addkional O&M costs (for 2,000 af & assuming CRSP power rates); Unestimated costs might also include the possible purchase of water from Wolford Mtn. Reservoir or other sources to replace water pumped during a mainstem call if needed in addition to water from the 5.000 al Green Mtn. pool. Storsge in Rifle Not estimsted. Gap Reservoir has never been stopped due to the Cameo Call(or other mainstem Colorado River call). 24 - Could water stored in RG during average or wet years be carried over to 8 dry year? (this water would be Ilrstto spill, but il k is to be spilled, could k be timed to coincide with spring peak flow needs for the endangered Ilsh?l . Woutd have to examine ability to use Green Mtn Res. as a replacement source. - May be possible to operate pumps more in the early part of dry years to maximize effectiveness. - Would CRSP power with low rates be avansblel - Would there be a problems with 8 pumping decree for irrigation only7; any problems with expanded use 1 . Would storage or recreation use in Harvey Gap be affsctedl . Would need to involve FIC. - Need more info on deliveries to PCSA to analyze this option. . Should also look at other options for pumping water suppfy using existing or new facilities. . If 8 mainstem Colorado call was to stop Rifle Gap storage, replacement releases could be cslled lor lrom the 5,000 sl reservation in Green Mtn. Reservoir. - Calls by senior oil shale rights would be treated similarly. . Would not address Rifle Creek call.
