<br />G01l727 <br /> <br />using the Revised StateMod and C1 Data Set (Fifth Revision) with calculated exchanges using Denver <br />Water's PACSIM are presented in Appendix N. <br /> <br />2.3.3 Riprap <br /> <br />For purposes of determining the feasibility of each alternative for contributing toward the 20,000 acre- <br />feet, the Final PBO specified the baseline conditions of the StateMod C1 Data Set were to include the <br />RIPRAP projects (see Appendix D ofUSFWS, December 22,1999). The StateMod C1 Data Set as <br />originally received from the State at initiation of the Phase 2 investigation did not have the following <br />components of RIP RAP adequately incorporated into the C1 Data Set: <br /> <br />. 5,000 acre-feet per year from Ruedi Reservoir, <br /> <br />. An additional 5,000 a~re-feet in 4 out of 5 years from Ruedi Reservoir, <br /> <br />. 10,825 acre-feet per year from Ruedi Reservoir under long-term lease, <br /> <br />. 10,825 acre-feet per year on a permanent basis divided equally between east slope and <br />west slope water users. At the present time, this requirement is being met on an <br />interim basis by Williams Fork and Wolford Mountain Reservoirs. A permanent, long <br />term solution will have to established in the future (see section 1.3.1). This permanent <br />solution may not involve the same components as the interim measures. <br /> <br />. 6,000 acre-feet per year from Wolford Mountain Reservoir, and <br /> <br />. Up to 28,400 acre-feet per year of water resulting from construction of improved <br />water management features for the Grand V alley Water Management Project. <br /> <br />Implementation of necessary revisions to incorporate the RlPRAP projects into the C1 Data Set <br />resulted in the C1 Data Set Fourth Revision (see Table 2). <br /> <br />2.3.4 CROP <br /> <br />CROP is a voluntary program, the participation in which is determiried on a yearly basis. Individual <br />participation in CROP is dependent on conditions that are present each year, including snowpack, <br />forecasted streamflows, and reservoir storage levels, among others. CFOPS is perceived to be a firmer <br />commitment, once made, as part of the Biological Opinion. CFOPS will likely be expected to operate <br />each year that flow in the stream in the 15-Mile Reach is within the target range during the spring run- <br />off. There is no guarantee that CROP will actually provide water every year. <br /> <br />I As indicated above in the Assumptions and Analysis Procedures section, the Phase 1 report indicated <br />that CROP would not be initially included in the baseline hydrology to be used in Phase 2, but <br />appropriate sensitivity analysis could subsequently be completed to determine if CROP would affect <br />the feasibility of specific alternatives to produce the 20,000 acre-feet release. This is the procedure <br />used in Phase 2. The CROP releases/bypasses investigated in Phase 2 are detailed in Table 3. <br /> <br />It is recommended that the Coordinated Reservoir Operations Group be the entity to actually make <br />decisions when to release or otherwise make water available from the average annual 20,000 acre-feet. <br /> <br />P:\Data \GEN\CWCB\19665\Repon Phase 2\FinalRepon12.02\Fin:u_ Draft _Repon(1-03).doc <br /> <br />20 <br />
