E. Ponds Of0 and 012 Deoletions. <br />Seneca Yoast Mine Pond 010 will be constructed on an uttttamed tributary of • <br />Scotchman's Gulch, which is a tributary of Grassy Creek. Storage of surface <br />water in Pond 010 will therefore t:atue depletions to Grassy Creek and the <br />Yampa River. <br />Seneca Yoast Mine Pond 012 wall be cotuttucted oa an nnn~med tributary of <br />Sage Creek. Stooge of surface water in Pond 012 will therefore catLSe <br />depletions to Sage Creek and the Yampa River. <br />F. Auttmentation of Grassv Creek and Yamna River. <br />Pond 010 will be an alte:tnate point of storage for the Sage Creek Reservoir water <br />nigh[ and use of such water will be limited [0 45.5 acre-feet annually for <br />industrial purposes, evttporazion and maintenance of storage reserves. The use <br />of the Sage Creek Reservoir storage right will be limited to those times when the <br />Sage Creek Reservoir right is in priority and wazer is physically and legally <br />available at its original point of storage: in addition, during the irrigation season <br />storage will be limited to those quantities of water flowing pazt the Sage Creek <br />Ditch to the Yampa River. During other limes. water will be stored in Pond 010 <br />under its own water right or its ou[-of-priority storage of wazer will be replaced <br />b}• storage releases from Applican['s Wadge Pi[ Reservoir or by contract releases <br />from Stagecoach Reservoir. <br />The Yoas[ Mine Shop Well will cause depletions to Grassy Creek az the ra[e of <br />10.27 percent of the annual pumpage az 15 years. If the well produces 41 acre <br />feet in a given year, the depletions to Grassy Creek will be 4.21 acre fee[. in <br />order to replace out-of-priority depietiotu [o Grazsy Creek during the irrigation <br />season. Pond 010 will retain 2.11 acre feet in storage for release to Grazsy <br />Creek. <br />Pos[-mining depletions will be limited to recovery from pumping of the Yoazt <br />Mine Shop Well. and will rapidly drop to less than 5~I of the average annual <br />pumpaee. Should the Division Engineer determine Iha[ junior water righu are <br />being adversely affected by these post-mining depletions, releazes may be <br />determined by Applicant's ground wazer depletion model, and releases called for <br />from Stagecoach Reservoir. Recovery will be virtually complete 20 years after <br />mining is compltted. <br />G. Auementation of Saee Creek. <br />Pond O1Z will supply water to the mine for non-potable uses. ]t will be used az <br />an alternate poinu of storage for the Sage Creek Reservoir wazer nigh[ and. an <br />alternate point of diversion for the Bates Ditch wazer righ[. Stooge under the <br />Sage Creek Reservoir wazer right will be limited to 45.5 acre feet annually for <br />industrial purposes, evaporazion and maintenance of storage reserves. The use <br />of the Sage Creek Reservoir storage right will be limited to those times whrn the <br />Sage Creek Reservoir right is in priority and wazer is physically and legally <br />available az iu original point of storage; in addition, during the irrigazion season <br />OF FACE AND DECREE <br />95 Cw 071 8 <br />~~ <br />LJ <br />16-4-20 <br />
