Site Drainage: Surface drainage flows northeast over the waste rock area to an earthen berm, <br />• which directs the flow to the northwest into a temporary sediment trap on the northwest side of <br />the site. The trap discharges to the north into a tributary of Big Gypsum Creek, an intermittent <br />creek located approximately 3/4 mile north of the mine workings area. Big Gypsum Creek <br />ultimately discharges west to the Dolores River, which ultimately discharges northwest to the <br />Colorado River. The topographic lines on Figure 2B in Appendix A depict the site flow pattern, <br />and Figure 1 shows the regional topography. <br />Table 3-2.
