~ • i <br />I estimated discharge at a point adjacent to the mine site of about 20 cfs. <br />The mine discharges water which exits the adit and passes through a <br />small, shallow (60 ft. long, by 20ft. wide, by 2 ft. deep) settling basin <br />' located adjacent to the portal. The discharge was observed and sampled in <br />August, 1987. According to the landowner, the drainage remains essentially <br />' constant; at the time of the field visit the flow was estimated to be about <br />0.5 to 0.6 cfs. The mine drainage was observed to be remarkably clear and <br />' supporting a population of insects and vegetation. The water continues <br />' downslope where it then enters Gold Creek. The mine drainage is currently <br />being evaluated to determine its quality. Although the quality of the <br />' water is not specifically known at this time, the apparent quality as noted <br />above would indicate that it is probably not significantly metal-charged. <br />' In addition, one nearby mine in the same geologic environment (the host <br />t rock in this area is predominately siliceous) has drainage which naturally <br />meets effluent limitations. <br />t No water is expected to be used in conjunction with the operation. <br />ldater for domestic consumption will be brought in to the site or obtained <br />' from the landowner. <br />1 <br /> <br /> <br />1 <br />~J <br />1 <br />' -15- <br />
