3. Applicants further request a conditional storage <br />right by construction of an on site pond located above the water <br />table. The storage pond capacity requirement during the active <br />mine period, will not exceed 8.06 acre-feet. The long term post- <br />mine winter augmentation storage right of 6.56 acre-feet will <br />account for a release capacity of 5.09 acre-feet and the <br />associated 0.56 acre-feet of evaporative losses and 0.91 acre- <br />feet of uncredited leakage. Water for augmentation will be taken <br />from a total "surplus" historical consumptive use of 19.97 acre- <br />feet during the months of May through October and placed in the <br />augmentation pond. <br />4. Applicants have also requested a change in use of <br />Sunrise Ditch Priority #13. 24.25 acres of 50.98 irrigated acres <br />will be converted to and governed by the augmentation plan <br />resulting in 24.2550.98 of 1.03 c.f.s. or 0.49 c.f.s. <br />transferred to the augmentation plan. The use will be for <br />wildlife, piscatorial, recreational, industrial and livestock. <br />The remaining 26.7350.98 of 1.03 c.f.s. or 0.54 c.f.s. will <br />remain unchanged. The Sunrise Ditch diverts from the Uncompahgre <br />River at a point in the SEA SW~ SEA of Section 20, Township 49 <br />North, Range 9 West, N.M.P.M., 1900 feet from the west section <br />line and 2100 feet from the south section line. <br />5. The property is currently leased by Western Gravel, <br />Inc. with permitted mine NR-34 for the extraction of gravel. The <br />pit will be developed on a 50.98 acre tract of formerly irrigated <br />land owned by the Applicant owners,. The property has been used <br />for growing various crops including alfalfa, pasture grasses, <br />corn and beans. 1.03 c.f.s, of priority irrigation water has <br />been delivered to the site from the Sunrise Ditch which holds <br />Priority 13, Adjudication date of June 30, 1890. <br />6. Development of the site will occur in phases that <br />may encompass a span of more than fifteen years. The <br />augmentation plan therefore will be implemented in corresponding <br />phases. The plan will utilize consumptive use credits from the <br />dry up of formerly irrigated crop land to offset evaporation <br />losses from the pond that occurs during the irrigation season. <br />Evaporation losses that occur at other times of the year, or that <br />occurs in excess of the consumptive use credits will be replaced <br />with water released from the augmentation pond. <br />7. The estimated monthly distribution of annual net <br />evaporation has been determined based on SCS TR-34 Site Data for <br />Montrose, Colorado, and with a projected annual production rate <br />of 150,000 ton~year consumptive use will occur as moisture <br />removed with the mined product. It is estimated that 4~ by <br />weight will be consumptive use, as undrained entrapped moisture. <br />In determining the necessary augmentation requirements, the <br />historic consumptive use is to be subtracted from the future <br />-2- <br />
