Spring 10-13 watershed. <br />• <br />Stevens (~tlch <br />Eleven monitored springs are located within the Stevens Gulch drainage (refer to <br />Table 5 arri Map No. 4-1) . Spring & Pond 28 aryl 12-4 were not actively monitored <br />during 1993 as they were known to lie clearly beyorrl the area of potential mine <br />impacts. Sufficient data had been collected fro[n each of these sites to <br />adequately duracterize the pre-mining hydrology. Spring & Porn 7-4 was <br />inadvertently not monitored either as the wrong field location was being checked <br />for this site. Spring & Pond 7-4 overlies an area of the East mine inactive <br />since 1983. Spring & Pond 19 lies outside the area of potential mine ing~acts <br />given minirrct development to date. No measurable flows were observed from SP-19 <br />during 1993 although the pond was observed to contain water. Spring & Porn 23 <br />• overlies an are of the East mine inactive since 1984. No retreat mining has <br />occurred in the vicinity of SP-23. `This site was visited three times during 1993 <br />with flows observed and field parameters collected consistent with prior <br />measurements. No water quality samples were collected as a sufficient database <br />already exists to characterize water quality at this site. Spring & Pond 7-5 <br />overlies an are of the East mine inactive since 1983. This site was visited <br />three times during 1993 with fleas observed arcl field parameters collected <br />consistent with prior measurements. No water quality samples were collected as <br />a sufficient database already exists to characterize water quality at this site. <br />Spring 25 lies below an area of the East mine inactive since 1982. This site was <br />observed flowing in June 1993 with field parameters collected consistent with <br />prior measuren~nts. A water quality sample was not wllected as a sufficient <br />database exists for this location and no further mining had oaur-red in the <br />vicinity of this site. Spring 25 has been identified as an adjudicated water <br />riot within the permit area which will be monitored further during 1994. <br />13 <br />
