This aggregated water right can be represented with an appropriation date of June 10, 1927 (Administration No. 29228.28284) with a capacity of 118.9 ets. Depletions to the flow of Tenmile Creek are limited by the volume of water physically and legally available for diversion on the Climax property, further limited by the mining and milling requirements. From engineering studies provided by Climax's water rights consultant. a time series representing the historic stream depletion to Tenmile Creek has been prepared for the CROSS study period (1975 through 1991) and is included in the CROSS database. Because it represents depletions. there are no return flows associated with this time series. Depletions attributable to the Eagle and Arkansas River imports are relatively small and can be neglected in the CROSS modeling. Henderson Mine and Mill (WOlD 5110701 - The Henderson Mine is also owned by the Climax Molybdenum Company. It is an underground mine located in the South Platte drainage basin near Berthoud Pass. The mine was opened in 1977 and it has been operated almost continuously since that date, Water is pumped from the mine to maintain dry working conditions and this water is discharged into a tributary of Clear Creek. Because the mine and mine water discharge is located in the South Platte River basin, this operation has no effect on stream flows in the Colorado River basin. Ore from the mine is hauled from the mine through a 12-mile underground train tunnel to the Henderson Mill. located in the Ute Creek drainage basin, a tributary of the Williams Fork River, upstream of Williams Fork Reservoir. The milling process employed at the Henderson Mill is generally identical to the process used at the Climax Mine. based on flotation of molybdenum concentrate and slurry transport of tailing for deposition in large tailing ponds. Water is used and reused in the milling process through an elaborate 1-3
