The surface water <br />monitoring system for the Project includes 17 stream stations, including 10 continuous recording <br />sites and 7 sites with instantaneous flow measuring devices. The surface water monitoring system <br />remains the same as in WY2002 and is divided into three general hydrologic areas: <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 the monitoring sites are shown on Map 2. The following discussion of surface <br />water stations on the major drainages and tributaries to these drainages is presented from upstream <br />to downstream in the mine property. A summary of the surface water monitoring system is <br />presented in Table 2 and a discussion of WY2003 hydrologic data is present in Section 5.1 of this <br />report. <br /> <br />September 2004 HydroGeo, Inc. <br />
