4.3.4 Reservoir Target File - yampaT.tar <br />Reservoir EOM content targets (or monthly rule curves) are required to operate the Yampa Model. <br />Two target files were created for the Yampa River basin, a historical target file (yampaTH.tar) and a <br />target file that reflects the current operating policies at each reservoir (yampaTB.tar). The <br />yampaTB.tar file sets the maximum target at each explicitly modeled reservoir to full and the <br />minimum content to zero. For the aggregated reservoirs the targets were set to meet a 25% release in <br />July, 50% release in August, 25% release in September and 100% full the remainder of the year. For <br />the aggregated stockponds, the targets were set to full capacity. The yampaTH.tar file sets the <br />maximum target at each explicitly modeled reservoir to its historical EOM content and the minimum <br />content to zero. <br />Phase IHa enhancements that impacted the reservoir target file include adding three aggregated <br />reservoirs and three aggregated stockponds. Appendix D.11 describes these Phase IIIa enhancements <br />4.3.5 Reservoir Right File - yampaT.rer <br />The yampaT.rer file contains the water rights associated with each reservoir in the reservoir station <br />file. Table 4.3.5a summarizes for each modeled reservoir and right the administration number, <br />decreed amount, and whether the right is used as a first or second fill. Attributes of the water rights <br />were determined for different structure types as follows: <br />Water rights for explicitly modeled reservoirs were taken from the CRDSS database and <br />correspond to the State Engineer's official water rights tabulation. <br />Aggregated reservoirs were assigned up to eight rights, one from each of eight classes of water <br />rights. Each aggregated right was given a decreed amount equal to the sum of the decreed <br />storage for all water rights for the individual reservoirs represented by the aggregation, which fell <br />within the given water right class. Each aggregated right was given an administration number <br />calculated as the average administration number of all individual storage rights in the class (as <br />tabulated in the CRDSS database), weighted by the decree amount. Water right classes were the <br />same as those used for aggregating irrigation diversion rights (see Appendix D.5). <br />• Aggregated stock ponds were assigned a decreed amount equal to their capacity, and an <br />administration number of 1.00000. <br />Phase IIIa enhancements that impacted the reservoir right file include adding three aggregated <br />reservoirs and three aggregated stockponds.
