mining area, Calamity Draw, Tuttle Draw, and into a <br /> sublateral canal off the West Lateral Irrigation Ditch. <br /> Details are provided in Section 4. 3 . This transferral uses <br /> existing ditches and diversion structures. <br /> The water-rights issues requiring resolution can be <br /> divided into two separate but related areas. First, mining <br /> will result in consumptive use (C.U. ) of water, which must be <br /> provided for. Second, dewatering of the pits will remove <br /> water from the shallow ground-water system thereby affecting <br /> surface-water rights. Hence, a mitigation plan is required <br /> to prevent impact to these rights. Because the mitigated <br /> rights are associated with a historic consumptive use, no <br /> consumptive-use deficits result from the mitigation plan. <br /> The pit-inflow water represents a credit which offsets the <br /> water used for augmentation where downstream rights are <br /> concerned. <br /> The following table summarizes the annual water budget <br /> related to the mining operation. Peabody owns 27 shares of <br /> the Colorado Co-operative Company. This represents an <br /> average annual diversion of 273.3 acre-feet, and a <br /> consumptive use of 114.5 acre-feet. Calculation of the <br /> historical consumptive use, performed using the modified <br /> Blaney-Criddle method, is described in Section 4.2 . In <br /> addition, Peabody will have, if this plan is adopted, <br /> 7 <br /> GEOTRANS. INC. <br />
