• June through September. Site visitation attd water quality sampling requirements were met at these sites during <br />1999. <br />Tables 51 through 53 provide summaries of the 1999 Water Year data collected at Trout Creek surface Flow sites. <br />Tables 51 a and 53a provide period of record statistical summaries of collected data at sites 301, 69, and 1005. <br />Figures 10? through 1 I 1 provide graphical representations of water levels and selected water quality parameters <br />recorded at each site. For the most part, typical patterns were observed. Again, peak Flow estimates were derived <br />from extrapolated flow curves in some instances. <br />1999 Water quality parameters for these sites are typically within previously established ranges with a few <br />exceptions. At site 301 (Table 51) a new minimum value was recorded for lab pH; and a new maximum value <br />was recorded for cadmium. At site 69 (Table 52) new minimum values were recorded for lab pH, alkalinity, and <br />manganese. A[ site 1005 (Table 53) a new minimum value was recorded for lab pH; and new maxintutn values <br />were recorded for SAR, and amnia-free nitrogen. <br />Middle Creek: Two surface flow monitoring sites on Middle Creek are utilized. Site MC-I is located upstream <br />of any mining activities and requires monthly Flow attd field parameter measurements with quarterly water <br />qualiq- sample collection. Site 700 is located downstream of any mining activities and requires monthly field <br />parameter measurements with quarterly water quality sample collection. Flows at site 700 are monitored by the <br />USGS (Station 09343700). Water quality data is provided on Table 54 and 55 with plots of selected data <br />• presented on Figures 113 and 117. Due to the limited period for which data has been collected at site MC-l, <br />many new maximum and minimum values continue to be recorded during 1999. These changes in value are <br />insignificant at this time. <br />Four additional surface water sites required monitoring under the TCC program in 1999. Foidel Creek sites 14 <br />and 304, and Fish Creek sites 307 and 305. Monthh~ water levels were to be obtained from March/early April <br />through September. Thesz monitoring requirements were met during 1999. Tables 42 and 43 provide summaries <br />of [he 1999 Water Year data collected at Foidel Creek surface sites in conjunction with alluvial well monitoring. <br />Tables 49 and 50 provide summaries of the 1999 Water Year data collected a[ 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 tlovaing and four water quality sampling instances. Consequently, data beyond the <br />requirements of the TCC program is presented on Table 43. The weir at site 14 was washed out in May 1997. <br />Subsequent Flow measurements were generated by direct measurement of the stream. Sites 304, 307, and 305, <br />are monitored in conjunction with alluvial wells 008-AV-I and 2, 006-AZ-3, and 008-AU-3 respectively. <br />Figures 49, 50 and 63 provide graphical representations of data collected at these sites. 1999 Water Year data for <br />these sites is presented as Tables 43, 49 and 50. The historical summary of flow rate data for selected surface <br />sites is presented as Table 56. This [able also provides flow summary information for discharge sites 63, 109, and <br />• 115. <br />-9 <br />
