HYDROLOGIC CHARACTERIZATION AND MONITORING PLAN
4.2.1.4 Spring G-16
23
Spring G-16 is located in Sylvester Gulch east of the northeast mine panels area (Plate 1). This
spring issues from a sandstone bed above the F -seam and typically has highest flows in the
spring months. Hydrologic monitoring at this spring began in 1979.
4.2.1.5 Spring G-24 (Decreed Spring #8)
Spring G-24 is located in Sylvester Gulch east of the northeast mine panels area (Plate 1). This
spring issues from alluvium and is measured at the outflow of a plastic drainage pipe. It flows
seasonally and flow diminishes in late summer and autumn. Hydrologic monitoring at this
spring began in 1979.
4.2.1.6 Spring G-14 (Decreed Spring #7)
Spring G-14 is located in Sylvester Gulch east of the northeast mine panels area (Plate 1). This
spring issues from fractures in the base of a sandstone bed. It flows seasonally and flow
diminishes in late summer and autumn. Hydrologic monitoring at this spring began in 1978.
4.2.1.7 Spring G-22 (Decreed Spring #3)
Spring G-22 is located in the Sylvester Gulch drainage on a hillside on the west side of the
drainage, just south of a mine ventilation shaft and north of the northeast mine panels area (Plate
1). It issues from alluvium over a wide area and feeds a wetland on the west side of Sylvester
Gulch. Flow in this spring diminishes in late summer and autumn. Hydrologic monitoring at
this spring began in 1977.
4.2.1.8 Spring 35-3
Spring 35-3 is located in upper Deep Creek which is tributary to the North Fork (Plate 1). This
spring is located east of the SOD mine panels area. The source of this spring appears to issue
from alluvium. This spring has perennial flow, but shows strong seasonal variations with high
flows in the spring months. This spring has been monitored since 2006.
4.2.1.9 96-2-2 Area Spring
The 96-2-2 Area Spring is located in upper Deep Creek which is tributary to the North Fork
(Plate 1). This spring is located in the SOD mine panels area. The source of this spring appears
to issue from alluvium. This spring has been monitored since 2007.
4.2.1.10 Deep Creek Spring #2
Deep Creek Spring #2 is located in upper Deep Creek which is tributary to the North Fork (Plate
1). This spring is located in the SOD mine panels area. The source of this spring appears to
issue from alluvium. This spring has been monitored since 2007.
4.2.1.11 Deep Creek Trail Spring
Deep Creek Trail Spring is located in upper Deep Creek which is tributary to the North Fork
(Plate 1). This spring is located south of the southeast mine panels area and east of the SOD
mine panels area. The source of this spring appears to issue from sandstone bedrock. This
spring has been monitored since 2007.
