<br />G <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />was dropped from the list of wells covered by their augmentation plan. The <br />CRPOA in April 1998, applied to GASP to have the well reinstated under a Class <br />A contract. The Association paid back assessments and the well was reinstated <br />in August 1998. The well will be in GASP'S 1999 augmentation plan. For 1998, <br />the CRPOA leased 35 shares of Lupton Meadows water which was released to <br />the South Platte River to augment the well's depletions. <br />Data in Table 1 shows that the annual delivery has been about 113 acre- <br />feet per year. Knowing that there are four additional homes to be built which <br />would increase the demand by about eight percent, it is estimated that the future <br />delivery would be 120 acre-feet per year. Assuming that 70 percent of the water <br />delivered is consumptively used, because all irrigation is with sprinklers, the total <br />consumptive use would be 84 acre-feel per year. <br /> <br />IMPACT OF WELL PUMPING <br /> <br />The well is located approximately four miles from the South Platte River- <br />see Figure 1. The well is pumping from sands and gravels which are part of the <br />South Platte Alluvium. The impact of pumping the CRPOA well will be to <br />intercept water which in its natural course, absent pumping, would have reached <br />the South Platte River. The impact to the river would be in an amount equal to <br />the consumptive use caused by the CRPOA pumping. This depletion is now <br />occurring because water has been pumped and consumed within the <br />Subdivision for over 15 years. <br />The annual pumpage and consumptive use by CRPOA has been <br />increasing slightly each year as new homes are built. In his April 1998 report, <br />see Appendix B, Longenbaugh found the pumpage and consumptive use for <br />1997 to be 113.2 and 79.2 acre feet respectively. <br />Because of the four mile distance from the South Platte River and the 15 <br />years of previous pumping, it is estimated that the stream depletion will be <br />nearly a constant value each month but will increase each year as pumping <br />increases. This estimate is based upon the author's knowledge of calculated <br />depletions for other alluvial wells using either groundwater models or Glover <br />
