<br /> <br />Ground-water recharge to the reclaimed areas, there- <br />fore, would tend to move downward to the base of the <br />spoils and thence northwestward downdip along the <br />spoils-bedrock contact towards Eckman Park. <br />Eventually this added recharge to the ground-water <br />system would be reflected by a corresponding increase <br />in ground-water discharge to Foidel Creek and its <br />tributaries. <br />Although quantitative data are not available on the <br />permeability of reclaimed spoil materials in this <br />general area, it is estimated that ground-water <br />recharge would be increased as much as tenfold if the <br />final surface is left as rough as possible as pro- <br />posed in Chapter I and numerous water holes and check <br />dams are constructed along water courses. If so, <br />ground-water discharge to Foidel Creek from the pro- <br />posed lease tracts would increase from about 40 <br />ac-ft/yr (acre-feet per year) before mining to shout <br />165 ac-ft/yr after mining and reclamation (approxi- <br />mately 1,050 acres or 37 percent of tracts C-26644 <br />and C-26913 would be mined). Much, if not most, of <br />this additional water would be dissipated by evapo- <br />transpiration enroute to Trout Creek and the Yampa <br />River, however it would increase discharge from the <br />overall watershed by about 0.006 percent, a change so <br />123 <br />
