site now normally flows continuously. The TDS values at this site are <br />increasing. <br />NPDES 016 (NPDESI6). <br />This site exists on a Hubberson Gulch tributary in the II -W South area. <br />Pond 016 was nearly complete in September 2000, and first discharged in <br />April 2001. It is now monitored monthly. Average flow values for each <br />water year are: <br />2017 <br />0.100 <br />cfs <br />(monthly <br />measurements) <br />2016 <br />0.229 <br />cfs <br />(monthly <br />measurements) <br />2015 <br />0.129 <br />cfs <br />(monthly <br />measurements) <br />2014 <br />0.098 <br />cfs <br />(monthly <br />measurements) <br />2013 <br />0.130 <br />cfs <br />(monthly <br />measurements) <br />2012 <br />0.045 <br />cfs <br />(monthly <br />measurements) <br />2011 <br />0.317 <br />cfs <br />(monthly <br />measurements) <br />2010 <br />0.104 <br />cfs <br />(monthly <br />measurements) <br />2009 <br />0.102 <br />cfs <br />(monthly <br />measurements) <br />2008 <br />0.141 <br />cfs <br />(monthly <br />measurements) <br />2007 <br />0.081 <br />cfs <br />(weekly measurements) <br />2006 <br />0.103 <br />cfs <br />" <br />2005 <br />0.044 <br />cfs <br />" <br />2004 <br />0.037 <br />cfs <br />" <br />2003 <br />0.090 <br />cfs <br />" <br />2002 <br />0.037 <br />cfs <br />" <br />2001 <br />0.019 <br />cfs <br />" <br />This year's average flow value, 0.100 cfs, is above the average historic <br />(2001-2017) flow, 0.090 cfs. The timing of when flow values are <br />collected affects these averages. Mine pit pumping into this pond was <br />responsible for many of the high peaks present on the hydrograph in <br />previous years. An upper pond, 016A, was constructed in 2004. The <br />discharge culvert for Pond 016A failed in April 2011. It was not <br />repaired, and the pond was removed later in 2011. Pond 016 was cleaned <br />out in October of 2012. The TDS trend at this site is slightly <br />decreasing, with the peak occurring in August 2005. Baseline data from <br />14 <br />
