• <br />West Elk Mine 2009 Annual Hydrology Report 10 <br />3.1 Surface Water Monitoring Program <br />The surface lands of the West Elk Mine are drained to the north by the North Fork of the <br />Gunnison River, to the south by Minnesota Creek, to the west by Gribble Gulch, and to the east by <br />Deep Creek. The surface water monitoring program for the permit area includes 23 stream stations <br />comprised of 10 sites with continuous recording devices and 13 sites with instantaneous flow <br />devices. In WY 2008, eight surface water temperature monitoring sites were added to the <br />monitoring program as discussed in Section 3.1.5. <br />The stream surface water monitoring sites are divided into three general hydrologic areas <br />for discussion purposes: <br />• Stations in the Upper North Fork Drainage Basin. <br />• Stations in the Lower North Fork Drainage Basin. <br />• Stations in the Minnesota Creek Drainage Basin. <br /> <br /> <br />The locations of the 23 surface water monitoring stations are shown on Map 2 and the 8 <br />temperature monitoring site locations are shown on Figure 8. The following discussion of the <br />surface water stations on the major drainages and the tributaries to these drainages is presented <br />from upstream to downstream areas. A summary of the surface water monitoring program details <br />is presented in Table 3 and a discussion of the WY 2009 hydrologic impacts is presented in Section <br />5.1 of this report. The temperature data monitoring site details are summarized in Table 4. <br />June 2010 <br />HydroGeo, Inc.
