<br />• <br />A summary of consumptive uses is given below: <br />Use T e Basis Acre-feet r <br />Lake Evaporation Evap records + precip.data 9.37 <br />Gravel Excavation Evaporation Evap records, tonnage mined 1.32 <br />Dust Control -Roads Tonnage and road use 0.20 <br />Dust Control -Crush & Screen Plant Plant data and throughput 1.76 <br />Totals 12.65 <br />The numbers above are for worst case consumptive use since the lake is calculated at maximum <br />surface area and it is assumed that the full mining operation will be taking place at the same time. <br />The existing irrigation use for this water is approximately 1.4 acre-feet per acre per year. This is <br />slightly lower than other irrigated areas in Colorado because the feed ditch dries up in the later part <br />of the summer and the irrigation is not used after that time. The operation will take 9.93 acres out of <br />irrigation, therefore the consumptive use credit associated with this dry-up is 13.9 acre-feet. There- <br />. fore, the consumptive use credit associated with the change to industrial use is greater than the ac- <br />tual consumptive use needed, as calculated above. <br /> <br />Once mining and reclamation is completed 28 to 30 months after the operation commences, 4.4 <br />acres of the original permit area will remain as a lake and the remainder of the land will be restored <br />to irrigation use. <br />As shown in the lease with Box Elder Holding Company, United has leased the Following water <br />rights: <br />- Miner Martin Ditch on While River at stream mile 73.97 for 5.00 cfs. <br />-Jacobs Pump & PL White River for 4.00 cfs delivered by pump. <br />- White River Mesa Ditch Piceance Creek for 13.09 cfs. <br />These rights are more than adequate to cover the industrial use demands. <br />Piceance Pit 7101 <br />17 <br />
