Baseline data from Site SW-S2W-SG17 (WSH17) have been provided in <br />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 />and first discharged in April 2001. It is now monitored monthly. Average <br />flow values for each water year are: <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 <br />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 was 61% above the average historic (2001-2014) <br />flow, 0.0802 cfs. The timing of when flow values are collected affects <br />these averages. Mine pit pumping into this pond was responsible for many <br />of the high peaks present on the hydrograph in previous years. An upper <br />pond, 016A, was constructed in 2004. The discharge culvert for Pond 016A <br />failed in April 2011. It was not repaired, and the pond was removed <br />later in 2011. Pond 016 was cleaned out in October of 2012. The TDS <br />trend at this site is decreasing, with the peak occurring in August <br />2005.
