Monitoring at <br />• this spring began in 1996. <br />3.2.2.5 Spring G-1 a <br />Spring G-la is located in Sylvester Gulch on the west side of the drainage, north of the Box <br />Canyon panel area (Map 2). It issues from alluvium and is seasonal with moisture present only <br />during periods of snow melt or peak flow. Monitoring at this spring began in 1983. <br />3.2.2.6 Spring G-20 <br />Spring G-20 is located in middle Sylvester Gulch on the east side of the drainage. It is located <br />north of the Box Canyon panels and east of the mine facilities (Map 2). It issues from alluvium or <br />landslide material and disperses water through a grassy area. Monitoring at this spring began in <br />1979. <br />3.2.3 Springs above the B Seam in the Jumbo Mountain Area in the <br />North Fork Drainage Basin <br />3.2.3.1 Spring CR-12 <br />Spring CR-12 is located in Lone Pine Gulch north of the NW mine panels (Map 2). It issues from <br />alluvium on the south side of the gulch. This is a perennial spring, but the volume of flow <br />diminishes in summer and autumn. It is recommended that this monitoring station be deleted from <br />the hydrologic monitoring plan, because mining activities have moved well east of the Jumbo <br />Mountain area and there have been no measurable mining-induced impacts at this site. <br />3.2.3.2 Spring G-26a <br />Spring G-26a is located in Lone Pine Gulch north of the NW mine panels (Map 2). This spring <br />issues from alluvium and flows into a small pond. This spring is seasonal and flow only occurs <br />during peak flow conditions. It is recommended that this monitoring station be deleted from the <br />hydrologic monitoring plan, because mining activities have moved well east of the Jumbo <br />Mountain area and there have been no measurable mining-induced impacts at this site. <br />3.2.3.3 Spring G-28a <br />Spring G-28a is located in a north tributary to Gribble Gulch (Map 2). It is situated above the <br />westernmost panels in the NW mine panels. This spring issues from alluvium and is seasonal. <br />Flow usually occurs during peak flow and accumulates in a stock pond. It is recommended that <br />this monitoring station be deleted from the hydrologic monitoring plan, because mining activities <br />December 2007 HydYOGeo, Inc. <br />
