<br /> <br />9fark A. Steen <br />Tons of Ore Processed x 1/S x O.1C x O.G00735 = acre <br />feet of water retained in the concentrates. <br />This formula is based upon assume[ions that ore ton of concen- <br />trates will be obtained for every eight cons of ore processed, <br />and that the water retained within the concentrates will be 106 <br />by weicht. O.G00735 is the amount of water, in acre feet, in a <br />ton of water, The following formula shall be utilized to calcu- <br />late the annual consumptive use due to evaporation from the tail- <br />ings pond: <br />Surface atres x 2 feet = evaporation from tailings pond <br />(acre feet). <br />This formula assumes that two feet of water will evaporate from <br />each surface acre of water each year. pursuant to these <br />formulas, the total consumptive use is estimated to be 9.17 acre <br />feet per year for the proposed SU ton per day mill operating year <br />round, 29 hours per day. Applicant reserves the right to mini- <br />mize or prevent evaporation from the tailings ponds in the <br />future. <br />13. Applicant may increase the capacity of said operations. <br />Water usage shall be calculated pursuant to the formulas in <br />paragraph 12 (E) for any such increases. <br />14. Diversions made by the Left Hand Ditch Company in a dry <br />year have been approximately 0.74 acre feet per share with an <br />annual depletion to the South Platte Fiver syster„ of approximate- <br />ly 0.52 acre feet per share. Diversions and depletions were about <br />twice as much in years of above average precipitation. Therefore, <br />the Applicant's pro rata share of historic diversions basetl upon <br />said 20 shares in a dry year is approximately 14.8 acre feet per <br />}'ear with historic stream depletions of 10.4 acre feet per }•ear. <br />In a wet }•ear, Applicant's pro rata share of historic diversions <br />is approximately 32.15 acre feet per year with stream depletions <br />of 22.53 acre feet per year. <br />15, Applicant intends to divert the water associated with <br />said 20 shares at an alternate point of diversion locates on the <br />south bank of Left Hand Creek at a point whence the Southeast <br />corner of Section 2, Township 1 North, ~ar.ge 72 West, 6th P,FS. <br />bears S 34° 45'E, a distance of 1,590 feet, eoulder County. <br />i6. Diversions at this alternate point of diversion will be <br />made at a taaximun rate of SO gem and only during the historic <br />ire-igation season of the Left F:and Ditch Company (April 1 to <br />October 31). Applicant intends to store this water in presently <br />unused underground mine workings owned by applicant located in <br />Section 12, Township 1 North, °ance 72 West, 6th p.f•;., boulder <br />County. <br />17. The Applicant intends to divert water at the alternate <br />point of diversion under one of the two following alternatives: <br />a <br />
