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 />2015 <br />0.173 <br />cfs <br />(monthly <br />measurements) <br />2014 <br />0.199 <br />cfs <br />(monthly <br />measurements) <br />2013 <br />0.151 <br />cfs <br />(monthly <br />measurements) <br />2012 <br />0.053 <br />cfs <br />(monthly <br />measurements) <br />2011 <br />0.681 <br />cfs <br />(monthly <br />measurements) <br />2010 <br />0.225 <br />cfs <br />(weekly <br />measurements till 7/1, then monthly) <br />2009 <br />0.245 <br />cfs <br />(weekly <br />measurements) <br />2008 <br />0.272 <br />cfs <br />" <br />2007 <br />0.163 <br />cfs <br />" <br />2006 <br />0.162 <br />cfs <br />" <br />2005 <br />0.119 <br />cfs <br />2004 <br />0.080 <br />cfs <br />" <br />2003 <br />0.187 <br />cfs <br />" <br />This year's average flow was 10.5% below the average historic (2003- <br />2014) flow, 0.193 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. The TDS values at this site are increasing. <br />13 <br />
