2008 <br />0.350 <br />cfs <br />(monthly measurements) <br />2007 <br />0.044 <br />cfs <br />(weekly measurements) <br />2006 <br />0.054 <br />cfs <br />" <br />2005 <br />0.027 <br />cfs <br />" <br />2004 <br />0.014 <br />cfs <br />" <br />2003 <br />0.029 <br />cfs <br />" <br />2002 <br />0.006 <br />cfs <br />" <br />2001 <br />0.015 <br />cfs <br />" <br />2000 <br />0.051 <br />cfs <br />" <br />This year's average flow value, 0.030 cfs, is below the historic (2000- <br />2017) average flow value, 0.050 cfs. This year, flows reflected seasonal <br />variability, with the max discharge occurring in June. The timing of <br />flow value collection 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 WSSCl has been provided in Appendix El of the 2010 AHR. <br />NPDES 009 (NPDES9). <br />This site is located on the northern Sage Creek tributary and was <br />constructed in October 1991. This site first discharged on April 16, <br />1996. The water year average flow values since this pond began to <br />discharge are: <br />2017 <br />.000 cfs <br />(monthly <br />measurements) <br />2016 <br />.008 cfs <br />(monthly <br />measurements) <br />2015 <br />no flow <br />(monthly <br />measurements) <br />2014 <br />no flow <br />(monthly <br />measurements) <br />2013 <br />no flow <br />(monthly <br />measurements) <br />2012 <br />no flow <br />(monthly <br />measurements) <br />2011 <br />0.242 cfs <br />(monthly <br />measurements) <br />2010 <br />no flow <br />(monthly <br />measurements) <br />2009 <br />0.030 cfs <br />(monthly <br />measurements) <br />2008 <br />0.138 cfs <br />(monthly <br />measurements) <br />2007 <br />no flow <br />(monthly <br />measurements) <br />2006 <br />0.048 cfs <br />(monthly <br />measurements) <br />19 <br />
