<br />Memo <br /> <br />To: <br /> <br />15 Mile Reach Discussion Group <br /> <br />From: Robert Wigington <br /> <br />Re: June 28,1999 Draft ofPBO <br /> <br />Date: July 19, 1999 <br /> <br />Grand Valley Water Management pages 9 & 10. The 9,000 acre feet that will be spilled back <br />through the Palisade Pipeline is not included within the 12,000 acre feet of other spills that will <br />continue after the completion of the Grand Valley Water Management Project, but is additive to <br />the 19,400 acre feet of spills that will be reduced and managed by that project. This addition of <br />. 9,000 and 19,400 acre feet is the basis for a total of 28,400 acre feet in spill management for the <br />benefit of the 15 Mile Reach. <br /> <br />This 28,400 acre feet of spill management does not fully quantifY the flow management from this <br />project, however. Only two of the major components of that flow management are presented in <br />Table 1 ofthe PBO, and footnote 2 to this table is incorrect. The full amounts of excess surplus <br />water in Green Mountain Reservoir shown in this table can be legally protected under delivery <br />contracts for either hydropower or municipal, riverside parks. The 2,000-6,000 acre feet that <br />won't be protected by these contracts is a subset ofthe natural flow conservation, as identified by <br />the issue paper attached to Brent Uilenberg' s summary of the May 13, I999 conference call for <br />the Issue 5 Subgroup: 20,064, 22,7I9, and 16,145 acre feet in the 1992, 1993, and 1994 model <br />years. These flows are not stored in Green Mountain Reservoir, and, as Uilenberg explains, are <br />largely protected by diversion for hydropower. The amounts not so protected are 1,803, 7,827 <br />and 4,640 acre feet in the respective model years. The total natural flow conservation from <br />Uilenberg's issue paper should be added as another column to Table 1, and that column then <br />footnoted for these amounts being left legally unprotected. <br /> <br />Another column should be added for the 9,000 acre feet of spill management via the Palisade <br />Pipeline, and also be footnoted as being legally unprotected as to downstream diversions. <br /> <br />Finally, item 2 from Uilenberg's conference call summary should also be added to both <br />footnotes: "If and when the conserved natural flow water or Palisade Pipeline by-pass water is <br />depleted, these depletions will count against the 120,000 acre-feet of new Category 2 depletions <br />as defined by this opinion." <br /> <br />Recoverv A\!reement. page 16. 3rd paragraph. The discussion of the Recovery Agreement in this <br />paragraph should be strictly conformed to the language of the final agreement in Appendix B. <br />The following sentence should be added at the end of this paragraph: "Water users who chose <br />not to sign a Recovery Agreement within 60 days are not assured of the opportunity to sign one <br />at a later date." <br /> <br />1 <br /> <br />.- - -...' <br /> <br />. <br /> <br />8~ <br /> <br />No <br />.. <br />
