and began to discharge in February 2000. Average flow values for each <br />water year are: <br />2012 0.011 cfs (monthly measurements) <br />2011 0.300 cfs (monthly measurements) <br />2010 0.069 cfs (monthly measurements) <br />2009 0.064 cfs (monthly measurements) <br />2008 0.350 cfs (monthly measurements) <br />2007 0.044 cfs (weekly measurements) <br />2006 0.054 cfs " <br />2005 0.027 cfs " <br />2004 0.014 cfs " <br />2003 0.029 cfs " <br />2002 0.006 cfs " <br />2001 0.015 cfs " <br />2000 0.051 cfs " <br />This year's average flow value is 78% below the historic (2000 -2011) <br />average flow value, 0.051 cfs. This is the lowest average flow since <br />2001. This year, flow was intermittent. The timing of when flow values <br />are collected affects these averages. The TDS plot indicates a <br />decreasing trend, with the peak occurring in February 2000. This pond <br />receives stormwater only (i.e., no spoils water). Baseline data from <br />Site WSSC1 has been provided in Appendix El of the 2010 AHR. <br />- NPDES 009 (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.
