<br />N <br />diversions to prevent East Slope interests from deriving benefit of water stored <br />in Green Mountain. Stored water is released in an amount which brings the water <br />supply at Shoshone up to the decreed amount of 1,250 cfs. During such an <br />irrigation season call, owners of transmountain diversions can continue to <br />divert, provided that they release a like amount of water to the stream as <br />replacement for the water diverted out of priority. Deriver commonly uses this <br />technique, making its replacement releases from water stored in Williams Fork <br />Reservoir. <br />PRIORITY POSITION <br />Public Service Company's Shoshone Hydropower Plant water right for 1,250 <br />cfs is senior to many year round water users in the basin (see attached table). <br />These year round users need to have reliable water supplies in the winter season, <br />which is normally the period of lowest flow. Large transmountain diversion <br />projects typically operate whenever they can while in priority, and rely on <br />replacement releases from storage to extend their operating seasons. <br />Strict adherence to the Shoshone demand means that junior water users <br />upstream, including transmountain diversions, are prevented from depleting the <br />river. More water is in the streams above Shoshone, where diversions can <br />continue so long as there is stored water for replacement. <br />Below Shoshone, there are both transmountain diversions and industrial/ <br />municipal users who are junior and now benefit from the non-consumptive senior <br /> <br />3
