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 have been added in conjunction with new Fish Creek Alluvium well sites AVF- <br />13, AVF-14, and AVF-15. These are surface sites SW-13, SW-]4 (both added in August 2001), and SW-15 <br />(added in June 2002). These new sites require quarterly water ]eve] measurements (March through September), <br />and semi-annual field parameters and water quality sampling. Data relating to these sites is discussed further in <br />section 4.0 on Subsidence Impacts. <br />Tables 44 through 50, and 56 through 58 provide summaries of the 2004 Water Yeaz data collected at Fish Creek <br />surface flow sites. Tables 44A through SOA provide some historical summaries of collected data at each site for <br />comparison. Figures 64 through 95 provide graphical representations of water levels and selected water quality <br />parameters recorded at each site. Again, typical flow pattems were exhibited at these sites with spring runoff <br />periods accounting for the peak flows observed. In general, an inverse relationship between flow and field <br />conductivity was evident. 2004 water quality parameters for these sites were generally within previously <br />established ranges. <br />Note that former Site 1002 (located approximately four miles downstream of the Fish Creek Borehole mine <br />dewatering site) and associated alluvia] we11006-AW-2, were both eliminated in 2003 per TR03-42. <br />New surface sites SW-13, SW-14, and SW-]5 (Tables 56 through 58, and Figures 70 - 81) indicated elevated <br />concentrations for total recoverable iron in early June 2003, however iron concentrations dropped dramatically <br />(about an order of magnitude) by August 2003. With the exception of total recoverable iron, none of the values <br />recorded during the initial sampling episode fell outside the typical historical range of other surface sites on Fish <br />Creek. 2004 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 we11008-AT-1. <br />Tables 51 through 53 provide summaries of the 2004 Water Year data collected at Trout Creek surface flow sites. <br />Tables SIA and 53A provide historical summaries of collected data at sites 301, 69, and 1005. Figures 96 <br />through 105 provide graphical representations of water levels and selected water quality parameters recorded at <br />each site. For [he most part, typical seasonal flow pattems were observed. 2004 Water quality parameters for <br />these sites are typically within previously established ranges. <br />119iddle Creek: Two surface sites on Middle Creek were historically utilized for monitoring flow. Site MC-was <br />located upsveam of any mining activities and site 700 is located downstream of any mining activities. Note that <br />• sites MC-] and 700 were both eliminated from monitoring in early 2003, per TR03-42. Refer to previous AHRs <br />for POR data. <br />11 <br />
