2.04.7 Hydrology Description <br />. The Jenkins Ditch No. 1 and 2 do not have headgates. Their source of water is <br />apparently seeps from the Fire Mountain Canal. <br />The Stephens Ditch is unknow to the Water Commissioner. It is apparently a <br />ditch that at one time derived its flow from Stephens gulch. <br />The main source of water for the Lennox Ditch and Stewart ditch is the North <br />Fork of the Gunnison River. Both ditches are located south of the River so <br />surface run-off from the mine site is not a concern. <br />The source of water for the Terror Ditch is Terror Creek and Terror Creek <br />Reservoir. The source of water for the Terror Creek Reservoir is Alder Creek, a <br />tributary of Hubbard Creek. <br />The quality of water in the Fire Mountain Canal and Deer Trail Ditch could be <br />adversely affected by surface run-off from the mine site. However, because run- <br />offfrom the disturbed areas will be passed through one of three sediment ponds <br />or treated with alternative sedimentation control, any potential adverse affect <br />related to the mine operation will be eliminated or at least minimized. The quality <br />of water in the Fire Mountain Canal and Deer Trail ditch could also be adversely <br />affected by mine-water discharge from the B-Seam or D-Seam. If continuous <br />mine discharge were to occur from either or both Seams, the effluent would need <br />to be piped over or around the Deer Trail Ditch and the Fire Mountain Canal to <br />avoid any potential quality degradation. <br />Industrial use of water in the permit and adjacent area is restricted to the use by <br />the Terror Creek loadout. The loadout obtains its water from a well and the Fire <br />Mountain Canal. The mine's potential impact on both of these water sources is <br />discussed above. <br />The United States Fish and Wildlife Service (USFWS) considers any <br />consumptive use of water by the mine to deplete the flow in the Colorado River. <br />Water depletions in the Upper Colorado River Basin have been recognized as a <br />major source of impact to endangered fish species (USFWS 2/93). The Operator <br />will agree to implement the conservation measures that the USFWS believe are <br />necessary to offset this impact. <br />Wildlife use of water in the permit and adjacent areas is for subsistence. Wildlife <br />use the perennial streams, springs and ponds. It is possible the mine could <br />impact some of the springs or ponds. If this impact occurs, the Operator will <br />mitigate this water loss by constructing or repairing pond(s) and augmenting the <br />flow with water from the mine or from the Deer Trail Ditch. <br />In the event that contamination, diminution, or interruption in the underground or <br />surface water supplies result from coal mining operations, the following protective <br />measures would be followed. <br /> <br />PR-10 <br />2.04 - 37 - 09/26/08 <br />~ ~~RovEl~ <br />~i/ay~a8' <br />
