• Trout Creek Alluvial Groundwater: There are two Trout Creek alluvial monitoring wells, 008-AT-I, and a <br />privately owned well (Jones well). Figures 48 through 51 provide graphical representations of water level and <br />field conductivity information to date. Tables 27 and 28 provide 2006 data for these wells. <br />Well 008-AT-1 is monitored in conjunction with surface water site 1005. Figure 48 depicts the water level <br />relationship between these two sites. Monitoring was initiated on Trout Creek Alluvial wells back in 1994. <br />Middle Creek Alluvial Groundwater: TCC has no active Middle creek alluvial wells. Two Middle Creek <br />alluvial wells (AVM-1 and AVM-2) were incorporated into the monitoring network during 1996, however, per <br />TR03-42, these wells were abandoned in the Fall of 2003. Consult previous AHRs for earlier data. <br />3.3 Surface Water Monitoring <br />Monitorine/Sampline Requirements: Table 32 presents a summary of surface water monitoring frequencies, <br />which was last updated For Permit Revision 6 (PR 03-06 Exhibits 14-7 through 14-10) in March of 2004. Site <br />locations are shown on Figure 2 (a.k.a. Map 13A), Hydrologic Monitoring Plan of TR03-42 (as well as in Figure <br />2 of this AHR). Table A of Exhibit 14 specifies three seasonal monitoring episodes (i.e. October to February, <br />March to May, and June to September), each of which are further divided into two general categories of sampling <br />frequency: 1) "Regular" monitoring that is done continuously, and 2) "Contingent" monitoring that is done only <br />when there is a discharge from underground mine pumping at surface discharge sites 109 and/or 115. <br />• <br />2006 surface water data is provided in Tables 33 through 49. 2006 Water quality parameters for these sites were <br />typically within previously established ranges, unless otherwise discussed below. An historical summary of data <br />through 2006 has been provided in Tables 35a through Sla. <br />Foidel Creek: Four surface flow monitoring sites on Foidel Creek (in the vicinity of the TCC mine portals and <br />facilities areas) are utilized. Site 800 and site 14 are located upstream of the portal. Site 8 is located a short <br />distance downstream of the portal area and is monitored in conjunction with alluvial well 001-5-5. Site 900 is <br />located further downstream on Foidel above the confluence with Middle Creek. Former site 304 was located <br />further downstream of 900. Site 304 was eliminated in 2003 per TR03-42. <br />Tables 33 through 36 provide sumtaries of the 2006 Water Year data collected at each site. Tables 33a, 34a, and <br />35a provide POR statistical summaries of collected data at each site. Figures 52 to 59 and 102 to 105 provide <br />graphical representations of water levels and selected water quality parameters recorded at each site. Typical <br />flow patterns were exhibited at these sites with spring runoff periods accounting for the peak flows observed. At <br />all of these sites, the inverse relationship between flow and field conductivity continues to be evident. 2006 <br />Water quality parameters for these sites were within previously established ranges. <br />Fish Creek: Nine surface flow monitoring sites are utilized on Fish Creek. Site 16A replaced site 16 in 2000, <br />and is ]ocated upstream of the Fish Creek Borehole discharge site 115. Historical data for site 16 may be found in <br />previous AHRs. Site 307 is located approximately one mile downstream of the Fish Creek Borehole mine <br />dewatering site and is monitored in conjunction with alluvial well 006-AZ-3. Site 302 is located approximately <br />9 <br />
