Tables 33 through 36 provide summaries of the 2018 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. Water <br />quality parameters for these sites were within previously established ranges. A slight increase in conductivity at <br />site 8 was noted in 2016. This is attributed to increased discharge from Pond D, resulting from overflows from <br />the Area # 1 Pit (via DRMS site 7), which is partially fed by mine water as part of mine dewatering operations for <br />the old WMD and EMD. TC has been considering alternate treatment options for 10 RT (EMD) mine water. <br />Fish Creek: Nine surface flow monitoring sites are utilized on Fish Creek. Site 16A replaced site 16 in 2000, <br />and is located 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 />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. 0 <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 (both 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 2018 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 patterns were exhibited at these sites with spring runoff 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 />Fish Creek almost went dry in August 2018 and into the first part of September. Some surface sites (e.g. 1003) <br />saw unusual short term spikes in conductivity and TDS in 2013 and 2016. Some of this may be related to very <br />low, almost stagnant flows. TC will continue to monitor this. <br />New surface sites SW -13, SW -14, and SW -15 (Tables 4345, Figures 66-77) indicated elevated concentrations O <br />for total recoverable (TR) iron in early June 2003, however iron concentrations dropped dramatically (about an <br />12 <br />
