This year's average flow value is 60% above the historic average flow <br />value, 0.043 cfs. The timing of when flow values are collected affects <br />these averages. This year, flow was continuous. The TDS plot indicates a <br />decreasing trend. Baseline data from Site WSSC1 has been provided in <br />Appendix El. <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. The water year average flow values since <br />this pond began to discharge are: <br />2010 0.000 cfs (monthly measurements) <br />2009 0.030 cfs (monthly measurements) <br />2008 0.138 cfs (monthly measurements) <br />2007 0.000 cfs (monthly measurements) <br />2006 0.048 cfs (monthly measurements) <br />2005 0.000 cfs (monthly measurements) <br />2004 0.000 cfs (monthly measurements) <br />2003 0.000 cfs (monthly measurements) <br />2002 0.000 cfs " <br />2001 0.000 cfs " <br />2000 0.000 cfs It <br />1999 0.005 cfs (weekly m easurements) <br />1998 0.165 cfs it <br />1997 0.095 cfs <br />1996 0.065 cfs it <br />No flow was observed at this site this year. The timing of when flow <br />values are collec ted affe cts these averages. Review of this site's TDS <br />plot indicates a decreasing trend. Baseline data for this site (WSS3) <br />has been provided in Appendix El. <br />- Surface Water Site SW-S2W-FG4 (WSSF3). This site is situated on Sage <br />Creek downstream of the impacts from the Seneca II-W Mine (NPDES 009 and <br />015). Monitoring of this site commenced in September 1990. This site <br />recently displays a stable TDS trend (SF = 0.5). Baseline data for this <br />site has been provided in Appendix E1. <br />17
