West Elk Mine 2008 Annual Hydrology Report 10 <br />• <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 Gunnison <br />River, to the south by Minnesota Creek, to the west by Gribble Gulch, and to the east by Deep <br />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 using instantaneous flow <br />measuring devices. In WY 2008, eight surface water temperature monitoring sites were added to <br />the monitoring program as discussed in Section 3.1.5. <br />The stream surface water monitoring sites are divided into three general hydrologic areas for <br />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 />The locations of all 23 surface water monitoring stations are shown on Map 2 and the 8 <br />temperature monitoring sites are shown on Figure 8. The following discussion of the surface water <br />• stations on the major drainages and the tributaries to these drainages is presented from upstream to <br />downstream areas. A summary of the surface water monitoring program details is presented in <br />Table 3 and a discussion of the WY 2008 hydrologic impacts is presented in Section 5.1 of this <br />report. The temperature monitoring site details are summarized in Table 4. <br /> <br />June 2009 HydroGeo, Inc.
