<br />9. In the event that a senior water right is activated on Sage Creek such that <br />water is not available for storage in Pond Y-I during the non-irrigation season, <br />Peabody will haul water to Pond Y-I or to points along Sage Creek designated <br />by the Water Commissioner from Wadge Pit Reservoir. Such water will be <br />released directly to Sage Creek or from Pond Y-I in the same manner as <br />described in Item 8. <br />10. Up to 50 acre-feet of water is available to Peabody in Stagecoach Reservoir <br />under a contract with the Upper Yampa Water Conservancy District. Such <br />water will be released from Stagecoach Reservoir to replace Peabody's out-of- <br />priority depletions with respect to senior priorities on the Yampa River during <br />the non-irrigation season. Components include water used to replace out-0f- <br />priority storage in Pond 006 and Pond Y-I, historical return flows from <br />irrigation of 20 acres under the J.C. Temple Ditch No. I, and depletions to <br />Sage Creek streamflow caused by Well No. I pumpage. <br /> <br />CONCLUSIONS AND RECOMMENDATIONS <br />I. Peabody Coal Company will begin operation of the Seneca II-W Mine in 1990 <br />and coal will be extracted through 2004. The domestic water demands will be <br />about I.0 acre-foot per year. Industrial water demands, primarily for dust <br />suppression, will be about 25.0 acre-feet per year. <br />2. Well No. I will be completed in the Trout Creek Sandstone formation. It will <br />provide the domestic water supplies and will supplement the industrial water <br />supplies. Pond 006 will collect surface runoff and the discharge from the mine <br />pits and will regulate such water for industrial use, decantation, and flood <br />retention. <br />3. The consumptive use of the water used for domestic purposes will be about <br />10 percent of the water demand or 0.1 acre-foot per year. The water used for <br />industrial purposes will be completely consumed. Evaporation from Pand 006 <br />is estimated to be about 3.78 acre-feet per year. The total consumptive use <br />for this project, therefore, will be about 28.88 acre-feet per year. <br /> <br />4. Pumpage from Well No. I probably will not reduce streamflows in Dry Creek. <br />Streamflow depletion caused by Well No. I in the Grassy Creek, Fish Creek, <br />Trout Creek, Middle Creek and Yampa River probably will be less than 0.061 <br />16 <br />
