Hubberson Gulch / Dry Creek <br />- Surface Water Site SW- S2W -SG9 (WSH9) This Hubberson Gulch site is <br />upstream of NPDESI7 and all other mine related discharges in the II -W <br />South Expansion area. Monitoring at this site began in August 1997. No <br />monitoring was performed in the 1999 calendar year, but was resumed in <br />2000. This site is monitored in June and September. This site displays a <br />stable TDS trend. <br />- NPDES 017 (NPDESI7). This site exists on Hubberson Gulch in the II -W <br />South Expansion area. Construction of Pond 017 began on October 14, 2002 <br />and was completed in December 2002. It was monitored weekly (except when <br />inaccessible by truck) , but is now monitored monthly. Average flow <br />values for each water year are: <br />2013 0.151 cfs (monthly measurements) <br />2012 0.053 cfs (monthly measurements) <br />2011 0.681 cfs (monthly measurements) <br />2010 0.225 cfs (weekly measurements till 7/1, then monthly) <br />2009 0.245 cfs (weekly measurements) <br />2008 0.272 cfs " <br />2007 0.163 cfs " <br />2006 0.162 cfs " <br />2005 0.119 cfs " <br />2004 0.080 cfs " <br />2003 0.187 cfs " <br />This year's average flow was 23% below than the average historic (1990- <br />2012) flow, 0.196 cfs. The timing of when flow values are collected <br />affects these averages. Also affecting the historic flow average is a <br />large number of no flows' that occurred up thru 2007. This site now <br />normally flows continuously. However, this year, flow was intermittent; <br />no flow was observed in October or November of 2012. The TDS values at <br />this site are increasing. Baseline data from Site SW- S2W -SG17 (WSH17) <br />has been provided in Appendix E1 of the 2010 AHR. <br />- NPDES 016 (NPDESI6). This site exists on a Hubberson Gulch tributary <br />in the II -W South area. Pond 016 was nearly complete in September 2000, <br />
