z.oa.~ <br />facing slope of Terror Creek, the unnamed west to east flowing ephemeral <br />gulches which are tributary to Terror Creek are not currently within the long <br />term mine plan area. <br />• <br />U <br />PR-08 <br />/{ PPRovED <br />9~~S~o~ <br />Stephens Draw bisects the southwestern portion of the permit area. It is <br />characterized by steep to nearly vertical canyon walls. This Draw is an <br />intermittent stream with greatest flow to be expected during spring snowmelt <br />and significant precipitation events. Stockpond P-1 is located in Stephens <br />Draw in the southwest corner of the permit area. Monitoring performed <br />during 1984 shows this pond had discharge that ranged from 3 to 20 gallons <br />per minute. Flow monitoring for Stephens Draw immediately below the pond <br />show flows ranging from a seep to 1.58 gpm for the period of September <br />1995 through September 1998. <br />Four unnamed ephemeral drainages are located within the permit area <br />between Stephens Draw and Hubbard Creek. From west to east they are <br />named A-Gulch, B-Gulch, C-Gulch and D-Gulch. These gulches would only <br />be expected to have flow during spring snowmelts and significant <br />precipitation events. During 1995 and 1996 no discharge was observed from <br />these drainages. <br />Stockponds Within Permit and Adjacent Area: <br />Numerous stock ponds, all having a storage volume less than 20 acre-feet, <br />have been identified within the permit and adjacent area. These ponds are <br />man-made and historically serve as stockponds. Limited domestic stock use <br />has been made of these ponds in recent years. The ponds are sited to <br />collect run-off during the spring season and some are located to accumulate <br />flow from colluvial springs and seeps. Although the ponds are a significant <br />hydrologic feature of the permit area and their existence is currently <br />important to wildlife, total contribution of these ponds to the local water <br />budget is not significant. <br />Surface Water on Mine Site: <br />Surface water runoff associated with the surface operations is controlled by <br />the drainage plan. All surface runoff is either routed through sedimentation <br />ponds or treated with some form of alternative sediment control. <br />2.04-34- 7103 <br />
