The applicant states that no hydrologic effects due to mining will be noticed at Temple Well No. 1 (a domestic water right), a little south and west of the proposed mine site. Eventually, some effects will be seen at this well. The effects may be exhibited as increased levels of dissolved solids or other chemical parameters (sulphur, iron) and/or diminished quantity of water at the well. These effects will probably not be seen until a number of year after mining has reached its closest point to the well. Eventually, effects will diminish as the dissolved solids are leached from the spoils, and the aquifer characteristics return to normal. Locally, the major impacts of mining include effecting the quantity and/or quality of Springs S-1, S-5, 5-23, S-25, 5-41, S-45 and 5-51. Effects of mining at these sites will not be observed fora few years after mining is at its closest to these points. The Olson Spring (5-45), located about 9,000 feet downgradient of mining, could potentially be impacted. This spring, which issues from the Dry Creek alluvium, could suffer a degradation in water quality. This would occur if the Hubberson Gulch and Dry Creek alluvium are recharged by the spoils aquifer dish carge. As will be discussed in the Surface Water section of the Probable Hydrologic Consequences Assessment, this discharge will be of very poor quality. If the quality of Olson Spring, a domestic water right, is affected, the applicant will be responsible for replacing this impacted water with domestic quality water in the adjudicated quantities. The probable impacts to these sites will most likely be observed as a diminution in quantity of water available and a degradation of water quality. The impacts to Springs S-5, a colluvial spring, 5-41, a Williams Fork Formation springs, will be observed as a decrease in quantity of water available and a degradation of water quality. These springs will have their recharge or source areas mined out. Springs 5-41 and 5-23 both feed registered stock ponds. 5-41 feeds Temple Pond No. 2, a registered right with the State of Colorado. Spring 5-25 will apparently be mined through in the mid to late 1990's. Springs S-1 may be effected by a redirection of ground water potential toward the back filled pits. Dependent upon which side of the stream a colluvial spring, 5-23, is located, it may be impacted by mining. If it issues from the southwest bank, its recharge should not be affected. If it issues from the northeast bank, its recharge could be interrupted by mining. Spring 5-23 feeds Temple Pond No. 1, which is also registered. Both Pond Nos. 1 and 2 are number 1838 in basin rank. The applicant will be replacing Pond No. 2 with Sediment Pond 006 as a permanent structure. The other pond is up gradient of mining activities. It will probably be a number of years after mining comes closest to these springs that the effects in quantity and/or quality are observed. Again, this is due to the low transmissivity and storativity values associated with the local strata. -36-
