<br />002452 <br /> <br />The method utilized to determine the diversions and depletions was a function of: 1) the <br />structure type, 2) the decreed water right uses, and 3) the available data. The procedure used to <br />determine the diversions and depletions for each qualifying water right is described and coded <br />in Table 1 and is cross-referenced in the column entitled "Method" (column 20) in Appendix A. <br />Some water rights have more than one method code because the water right has multiple <br />decreed uses. In these cases, the total diversions and depletions for the right are determined by <br />summing the diversions and depletions associated with each applicable method code shown in <br />the method column. The diversions and depletions caiculated using the "codes" shown in the <br />method column are further limited by the decreed water right amounts for those instances where <br />the estimated diversions are greater than the decreed water rights. <br /> <br />The method used to determine the diversions and depletions associated with qualifying <br />irrigation water rights was based upon the StateCU computer model developed by the DWR. <br />The diversions for the junior water rights were taken from the column in the StateCU detailed <br />water budget output file entitled "Diversion by Priority-Junior" and the depletions from the <br />column entitled "Estimated Crop CU-By Water Rights-Junior". The basic engineering <br />assumptions used by the DWR in the StateCU model and supporting data sets were utilized <br />with the exceptions shown in Table 2. See the CDSS website htto:/Icdss.state.co.us for further <br />documentation on the StateCU computer model. <br /> <br />4.0 SUMMARY <br /> <br />The estimates of diversions and depletions contained in this report are derived from <br />information compiled by the Division 4 Engineer. A summary of the water rights, diversions, and <br />depletions that benefit from the Subordination Agreement is presented in Table 3. The following <br />table shows the depletions that occurred from water rights with priorities equal to or junior to the <br />Aspinall Unit priority of November 13, 1957 (administration number 39398.00000) pursuant to <br />the Subordination Agreement, during the period November 1, 2000 through October 31, 2001: <br /> <br />River Reach <br />Above Blue Mesa Dam <br />Blue Mesa Dam to Morrow Point Dam <br />Morrow Point Dam to Crystal Dam <br />Total <br /> <br />Depletion Allowance <br />(acre-feet) <br />40,000 <br />10,000 <br />10.000 <br />60,000 <br /> <br />2000 Depletions <br />(acre-feet) <br />7,054 <br />137 <br />1.136 <br />8,328 <br /> <br />4 <br />
