2.04.7 (1) (a) (i) (ii) A large number of the springs dry up in late summer. This is evidence of either a small amount of recharge to the aquifer or a rather limited aquifer system. If there was ' a large amount of recharge and a sufficient flow through the aquifer system assuming aquifer continuity, then there should be a large number of springs along the north ' facing hillside flanking the North Fork of the Gunnison River. 'phis is not the case. There is also no apparent ' concentration of springs issuing from the north facing walls of the Dry Fork of Minnesota Creek, a stream that cuts across the dip of the beds. These factors suggest local recharge and discharge. ' There are few springs (10 in all) issuing from below thel F seam. Almost all of these springs occur in either ' Sylvester Gulch or Gribble Gulch located about a mile west of the town of Somerset. h7hether this water originated further south on the block and flows through an aquifer system beneath the F seam, or is local recharge water, is unknown. Refer to Drawing 2.09.7(2)(a)-1 for locations of these springs. Table 2.04.7(1)(a)(ii)-13 ' summarize spring yields for the period October, 1978 to October, 1980. ' The alluvium acts as a more important aquifer though it is extremely limited. P.echarge to the alluvium is via runoff ' from the drainage basin. A study of the wells drilled in Sylvester Gulch shows that the alluvium is the primary aquifer ' in the area, and that waters are maintained within this aquifer by underlying shale and other impermeable strata. ' Pio domestic, irrigation, stock, commercial, or industrial dells ' are presently located in the lease block so there is little % use for any of the groundwater at present. mhe groundwater system relevant to mining activities on the Bear *":ine permit ' REVISED May 15, 1981 46
