The second storage right is part of the 40,720 acre -feet, conditional storage decree that was <br />transferred from the former Pleasant Valley Reservoir site, which is now the location of Lake <br />Catamount. The UYWCD made 20,854 acre -feet of this conditional water right absolute at <br />Stagecoach Reservoir. This right is used to fill all five accounts. <br />The third water right is associated with the former Four Counties Ditch No. 1 and No. 3, a conditional <br />direct flow right owned by the UYWCD that has been changed to allow storage in Stagecoach <br />Reservoir. From prior studies performed by W. W. Wheeler, it was determined that the yield of the <br />Four Counties water rights is generally limited to the seasonal runoff period (April through mid - July). <br />After mid -July, low streamflows and local calls on the tributaries preclude diversions by the Four <br />Counties rights. Based on this information, the 86 cfs is represented as a volumetric storage right of <br />12,979 acre -feet in the model. This right is used to fill all five accounts. <br />TABLE 4.5.4C <br />Stagecoach Reservoir Operating Rights <br />System <br />Admin # <br />Type <br />Description <br />OPR STAGECTOCRAIG(TRI) <br />45290.44866 <br />2 <br />Release to direct diversion <br />OPR STAGEC TO MT.W &SSP <br />42156.00002 <br />4 <br />Release to diversion by exchange <br />OPR STAGECOACH HYDRO <br />41727.39992 <br />2 <br />Release to direct diversion <br />There are two types of StateMod operations used to model the operating policies of Stagecoach <br />Reservoir: 1) a release from storage to a direct diversion downstream (type 2) and 2) a release from <br />storage in exchange for a direct diversion elsewhere in the system (type 4). <br />Operating right 1 releases water from account 1 to the Craig Power Station (440522). This right <br />allows for the transfer of Tri- State's water from Stagecoach Reservoir to the Craig Station as a result <br />of the Wessels transfer case. The administration number for this operating right is junior to both the <br />direct flow right at the Craig Station and the storage right at Stagecoach Reservoir. This operating <br />right is needed to allow the Craig Station to satisfy its demand using direct flow rights before calling <br />for storage water. The amount of water released to the direct diversion is restricted by the amount <br />currently available in the account. <br />Operating right 2 releases water from account 4 in exchange for water diverted by the Fish Creek <br />Municipal Intake (580642). The administration number for this operating right is junior to both the <br />direct flow right at the direct diversion and the storage right at Stillwater Reservoir. The amount of <br />water released to the direct diversion is restricted by the amount currently available in the account. <br />The UYWCD installed a hydroelectric generation facility on the outlet works of Stagecoach Dam and <br />produces electrical energy from the flows that pass through the reservoir, either as bypassed inflows <br />or as reservoir releases. Operating right 3 releases water from the UYWCD's 15,000 acre -feet <br />recreation pool to the hydroelectric plant if the bypassed inflows, together with the other project <br />releases, are less than 40 cfs. <br />Note that the operating policies modeled at Stagecoach Reservoir exercise only Tri- State's account <br />and the recreation pool. The other accounts were established in anticipation of future modeling <br />activities, such as modeling 100 percent of the water rights in the basin. <br />I Operating Criteria File 4 -27 <br />
