• three years worth of data available. While the new maximum values is noted for continued monitoring, these <br />value changes appeaz to be insignificant at this time. <br />Four additional surface water sites required monitoring under the TCC program in 1998. Foidel Creek sites 14 <br />and 304, and Fish Creek sites 307 and 305. Monthly water levels were to be obtained from March/early April <br />through September. These monitoring requirements were met during 1998. Tables 37 and 38 provide summaries <br />of the 1998 Water Year data collected at Foidel Creek surface sites in conjunction with alluvial well monitoring. <br />Tables 44 and 45 provide summaries of the 1998 Water Year data collected at Fish Creek surface sites in <br />conjunction with alluvial well monitoring.. <br />Site 14 is also monitored under the CYCC program as a surface water Flow site requiring monthly flow/field <br />parameter visits while flowing and four water quality sampling instances. Consequently, data beyond that <br />required to fulfill the TCC requirements is presented on Table 37. The weir at site 14 was washed out in May <br />1997. Subsequent flow measurements were generated by direct measurement of the stream. Sites 304, 307, and <br />305, are monitored in conjunction with alluvial wells 008-AV-I and 2, 006-AZ-3, and 008-AU-3 respectively. <br />Figures 40, 50, and 54 provide graphical representations of data collected at these sites. 1998 Water Year data for <br />these sites is presented as Tables 38, 44, and 45. The historical summary of flow rate data for selected surface <br />sites is presented as Table 50. This table also provides Flow summary information for discharge sites 62, 109, and <br />IIS. <br />• Middle Creek: Anew surface water monitoring station was established on Middle Creek in 1996. Site MC-1 is <br />located upstream of any mining activities and requires monthly flow and field parameter measurements with <br />quarterly water quality sample collection. Data collection commenced in August 1996. Water quality data is <br />provided on Table 49 with plots of selected data presented on Figures 102 and 103. <br />Due to [he limited period for which data has been collected at [his site, many new maximum and minimum values <br />continue to be recorded for site MC-1 during 1998. These changes in value are insignificant at this time. <br />NATURAL SPRING MONITORING <br />Two natural springs, SWI and SW2, located over previously mined areas in the Southwest Mining District <br />required monitoring during 1998. Quarterly flow, field parameter, and water quality samples are required for <br />these sites. All required monitoring was completed during 1998. Tables 56 and 57 provide summaries of data <br />collected at these sites during the year. No unusual water quality characteristics are apparent. No flow at site <br />SWl was observed only during of 1998. SWl flows typically occurred throughout the year prior to mining. <br />SW2 exhibited flows through the spring and summer of the 1998 Water Year. SW2 flows were historically <br />. sporadic during the period prior to mining. TCC will continue to monitor these locations. <br />-10- <br />
