• Ground-4•atur recharCc to [hc reel:~imcd areas, [hcru- <br />fore, could tend to Hove downward to tlic base of t:ie <br />spoils and thence nortln;est~.~ard ciowndip along the <br />spoils-hedrock contact tow: r~ls Ccl~ran Park. <br />Eventuall^ this ad~~d recharge to the ground-water <br />system would be reflected by a corresponding increase <br />in ground-water disci~argc to Foidel Creek and its <br />tributaries. <br />Although quantitative data are not available on t;.e <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 ceck <br />dams are constructed along water courses. If so, <br />ground-water discharge to Foidel Creel: from the pro- <br />posed lease tracts would increase from about 40 <br />ac-ft/yr (acre-feet per year) before mining to about <br />!~ 165 ac-ft/yr after mining and reclamation (appro::= <br />i mately 1,050 acres or 37 percent of tracts C-2664s <br />t and C-289].3 would be mined), Much, if not most, of <br />this additional water would be dissipated by evapo- <br />1 <br />transpiration enr~,:te to Trout Creelc and the Yampa <br />River, hocaever it would ipcrcasc discharge from the <br />overall watershed by about 0.006 percent, a ciianse so <br />t <br />i <br />~ , <br />1~3 <br /> <br />
