two miles downstream of the Fish Creek Borehole mine dewatering site. Site 305 is located upstream of the Fish <br />Creek Tipple and is monitored in conjunction with alluvial well 008-AU-3. Site 27A is located immediately <br />upstream of the Fish Creek Tipple discharge (a.k.a. CDPS discharge site 62). Site 1003 is located downstream of <br />the Fish Creek Tipple site 62. <br />Monitoring requirements at sites 307 and 305 require monthly water level measurements (March through <br />September), and semi-annual field parameters. However, per PR03-06, site 305 now requires semi-annual water <br />quality testing. <br />Three relatively new surface sites were added in conjunction with the new Fish Creek Alluvium well sites (AVF- <br />13, AVF-14, and AVF-15), in order to evaluate potential subsidence impacts in the area. These are surface sites <br />SW-13, SW-14 (bath added in August 2001), and SW-15 (added in June 2002). These sites require quarterly <br />water level measurements (March through September), and semi-annual field parameters and water quality <br />sampling. <br />Tables 37 through 45 provide summaries of the 2006 Water Year data collected at Fish Creek surface flow sites. <br />Tables 37a through 45a provide some historical summaries of collected data at each site for comparison. Figures <br />60 through 91 provide graphical representations of water levels and selected water quality parameters recorded at <br />each site. Again, typical flow pattems were exhibited at these sites with spring mnoff periods accounting for the <br />peak flows observed. In general, an inverse relationship between flow and field conductivity was evident. 2006 <br />water quality parameters for these sites were generally within previously established ranges. <br />New surface sites SW-13, SW-14, and SW-15 (Tables 66 through 77) indicated elevated concentrations for total <br />recoverable iron in early June 2003, however iron concentrations dropped dramatically (about an order of <br />magnitude) by August 2003. With the exception of total recoverable iron, none of the values recorded during the <br />initial sampling episode fell outside the typical historical range of other surface sites on Fish Creek. In 2006 iron <br />values were typically under 900 mg4, with the lowest concentrations seen at the most upstream site, SW-13. <br />Analytical data relating to these sites is discussed further in section 4.0 on Subsidence Impacts. <br />Trout Creek: Three surface flow monitoring sites on Trout Creek are utilized. Site 301 is located on Trout <br />Creek above the confluence with Middle Creek. Site 69 is located on Trout Creek below the confluence with <br />Middle Creek. Site 1005 (established in 1994) is located downstream of the confluence with Fish Creek and is <br />monitored in conjunction with alluvial well 008-AT-1. <br />Tables 46 through 48 provide summaries of the 2006 Water Year data collected at Trout Creek surface flow sites. <br />Tables 46a and 48a provide historical summaries of collected data at sites 301, 69, and 1005. Figures 92 through <br />101 provide graphical representations of water levels and selected water quality pazameters recorded at each site. <br />For the most part, typical seasonal flow pattems were observed. 2006 Water quality parameters for these sites are <br />typically within previously established ranges. <br />. Middle Creek: 2006 data for site Site 29, located on Middle Creek below the confluence with Foidel Creek, is <br />provided in Table 49. An historical summary of water quality data is provided in Table 49a, Figures 106 through <br />10 <br />
