are the same as Scenario A and aze those stated in the CPFD, Paragraph C. The results of this <br />analysis show that May and June are still months of net depletians (2,713 acre-feet). <br />Colorado made similaz estimates for Scenario B in 2008 as presented in Figure 2-2008, which also <br />reflects an adjustment for reduced development of native water supplies, an increased use of <br />reusable water supplies, and an additional population increase of 58,843 persons over the 2007 <br />population. The results of this analysis show again that May and June are months of net depletion.s <br />(2,972 acre-feet). <br />Colorado's Mitigation Measures <br />Colorado's mitigation commitment in the PRRIP is to undertake re-regulation projeets within <br />Colorado to shift water flows from periods of net accretion to periods of net depletian. The only <br />months with net depledons are the months May and June. Colarado has begun to re-time excess <br />flows in these months through managed groundwater recharge. Colorado began pumping two <br />recharge welis next to the river in January 2007 at the Colorada Division of Wildlife's Tamarack <br />Ra.nch recharge project and Colorado began pumping six more Tamarack wells in the first week in <br />March 2007. Colorado will continue to pump nn April 2007 until water is no longer available under <br />the South Platte compact and/or Colorado water law. In addition, Colorado has committed to <br />additional pumpung of recharge wells into the Peterson Ditch for this spring of 2007, depending <br />upon water availability, pursuant to Colorado's South Platte River water right demands and/ur <br />compact requirements. Colorado is also in the process of develaping leases with the owners of <br />private recharge projects for the lease of their excess rechazge accretions in May and June that result <br />from diversion of the net monthly accretions associated with the CPFD. A combination of these re- <br />timing activities will be utilized to accomplish Colorado's obligations under its Plan for Future <br />Depledons. Colorado will provide the results from their initial operations in the first annual <br />infor?nation report in January 2008. <br />Anuendix A <br />Adiustment for reduced native South Platte flow develoument <br />Throughout the Platte Basin, there has been an extended drought beginning in 2000. The use of <br />native South Platte flows with a priority date junior to July 1, 1997 (start date for new water related <br />activities) has been minimal during this drought. Colorado requests that the Governance Committee <br />consider a modification to the percent water supply from native South Platte flow development used <br />for new water related activities. A good indication and basis for this modification is the &equency <br />of river calls on the South Platte River. Figure 3lists the monthly percents for April through July <br />that a July 1, 1997 priority date woutd be out-of priority for the period 1998 through 2006. The <br />April through July period is the spring runoff period from snowmelt and is the time when South <br />Platte flow development would take place under junior water rights as assumed in the CPFD (i.e., <br />South Platte flow development assumed to occur at 5% in April, 40% in May, 50% in June, and 5% <br />in July). The call records used in this analysis are from the records of the Colorado State Engineer's <br />Office. The initialty assumed percent water supply source mix by region of the CPFD, Paragraph B, <br />was for the period 1998 through 2002. As listed in Figure 2, the weighted percent of time for a July <br />1, 1997 water ri,ght to be in-priority is 53% for 1998-2002 versus 33% for 1998-2006. <br />4
