West Elk Mine 2012 Annual Hydrology Report 12 <br />3.1 Surface Water Monitoring Program <br />The surface lands of the West Elk Mine are drained to the north by the NFGR, to the <br />south by Minnesota Creek, to the west by Gribble Gulch, and to the east by Deep <br />Creek/Raven Gulch (Map 2). The surface water monitoring program for the permit area <br />includes 23 stream stations comprised of 10 sites with continuous recording devices and <br />13 sites with instantaneous flow devices. In WY 2008, eight surface water temperature <br />monitoring sites were added to the monitoring program as discussed in Section 3.1.4. <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 of the Gunnison River Drainage Basin. <br />Stations in the Lower North Fork of the Gunnison River Drainage Basin. <br />Stations in the Minnesota Creek Drainage Basin. <br />The locations of the 23 surface water monitoring stations are shown on Map 2 and the <br />eight temperature monitoring site locations are shown on Figure 8. The following <br />discussion of the surface water stations on the major drainages and the tributaries to these <br />drainages is presented from upstream to downstream areas. A summary of the surface <br />water monitoring program details is presented in Table 3 and a discussion of the WY <br />2012 hydrologic impacts is presented in Section 5.1 of this report. The temperature <br />monitoring site details are summarized in Section 3.1.4. <br />June 2013 HydroGeo, Inc. <br />
