equivalent to the historical diversion file am aT.ddh . Section 5 describes how �Y P ) demands were <br />estimated for the calculated and baseline data sets. <br />4.2.5 Direct Diversion Right File - yampaT. ddr <br />The yampaT.ddr file contains water rights information for each structure in the direct diversion <br />station file, yampaT.dds. Table 4.2.5a presents the administration number and decreed amount for <br />each structure modeled. These two values were determined for different structure types as follows: <br />• Water rights for explicitly modeled structures were taken from the CRDSS database and match <br />the State Engineer's official water rights tabulation. Free water rights, with an extremely junior <br />administration number of 999999.00000, were added for these structures whenever historical <br />diversions were observed to exceed decreed rights during calibration. <br />• Aggregated irrigation structures were assigned up to eight water rights, one from each of eight <br />classes or mutually exclusive ranges of administration number. The decreed amount for each <br />right for a given aggregation was set to the sum of all water rights that 1) were associated with <br />individual structures represented by the aggregation, and 2) had an administration number that <br />l fell within the water right class. The administration number for each right was calculated as the <br />average administration number of the individual water rights in the class, weighted by their <br />decreed amount. See Appendix D.5 fora description of the water rights classes and how they <br />were established. <br />• Aggregated M &I water rights were assigned an amount equal to their depletion and assigned an <br />administration number of 1.00000. <br />1. <br />Diversions 4 -10 <br />
