when inaccessible by truck. Pond 015 was completed in late August 1999 <br />and began to discharge in February 2000. Average flow values for each <br />water year are: <br />2013 <br />0.040 cfs (monthly measurements) <br />2012 <br />0.011 cfs (monthly measurements) <br />2011 <br />0.300 cfs (monthly measurements) <br />2010 <br />0.069 cfs (monthly measurements) <br />2009 <br />0.064 cfs (monthly measurements) <br />2008 <br />0.350 cfs (monthly measurements) <br />2007 <br />0.044 cfs (weekly measurements) <br />2006 <br />0.054 cfs it <br />2005 <br />0.027 cfs " <br />2004 <br />0.014 cfs " <br />2003 <br />0.029 cfs " <br />2002 <br />0.006 cfs " <br />2001 <br />0.015 cfs " <br />2000 <br />0.051 cfs " <br />This year's <br />average flow value is 1896 below the historic (2000 -2012) <br />average flow <br />value, 0.049 cfs. This year, flow was intermittent. The <br />timing of when flow values are collected affects these averages. The TDS <br />plot indicates a decreasing trend, with the peak occurring in February <br />2000. This <br />pond receives stormwater only (i.e., no spoils water) . <br />Baseline data from Site WSSC1 has been provided in Appendix E1 of the <br />2010 AHR. <br />- NPDES 009 <br />(NPDES9). This site is located on the northern Sage Creek <br />tributary and was constructed in October 1991. This site first <br />discharged on April 16, 1996. The water year average flow values since <br />this pond began to discharge are: <br />2013 <br />no flow (monthly measurements) <br />2012 <br />no flow (monthly measurements) <br />2011 <br />0.242 cfs (monthly measurements) <br />2010 <br />no flow (monthly measurements) <br />2009 <br />0.030 cfs (monthly measurements) <br />2008 <br />0.138 cfs (monthly measurements) <br />2007 <br />no flow (monthly measurements) <br />16 <br />
