the peak TDS value occurring in August of 2013. Baseline water quality <br />statistics have been provided in Appendix E1 of the 2010 AHR. <br />- NPDES 005 (NPDES5). This sediment pond is located in the north mining <br />area on a tributary to Dry Creek referred to as the 005 Gulch. Mining in <br />this basin started in November 1992. Construction of this pond was <br />completed in July 1992 and the first discharge occurred on April 22, <br />1993. This pond was dredged in the summers of 1998 and 2001. The water <br />year average flows values since this pond began to discharge are: <br />2015 <br />0.012 <br />cfs <br />(monthly <br />measurements) <br />2014 <br />0.033 <br />cfs <br />(monthly <br />measurements) <br />2013 <br />0.044 <br />cfs <br />(monthly <br />measurements) <br />2012 <br />0.003 <br />cfs <br />(monthly <br />measurements) <br />2011 <br />0.214 <br />cfs <br />(monthly <br />measurements) <br />2010 <br />0.018 <br />cfs <br />(monthly <br />measurements) <br />2009 <br />0.060 <br />cfs <br />(monthly <br />measurements) <br />2008 <br />0.083 <br />cfs <br />(monthly <br />measurements) <br />2007 <br />0.038 <br />cfs <br />(monthly <br />measurements) <br />2006 <br />0.038 <br />cfs <br />(monthly <br />measurements) <br />2005 <br />0.021 <br />cfs <br />(monthly <br />measurements) <br />2004 <br />0.017 <br />cfs <br />(monthly <br />measurements) <br />2003 <br />0.026 <br />cfs <br />(monthly <br />measurements) <br />2002 <br />0.016 <br />cfs <br />(monthly <br />measurements) <br />2001 <br />0.018 <br />cfs <br />(monthly <br />measurements) <br />2000 <br />0.024 <br />cfs <br />(from monthly <br />measurements as of 12/99) <br />1999 <br />0.057 <br />cfs <br />(weekly measurements) <br />1998 <br />0.110 <br />cfs <br />" <br />1997 <br />0.033 <br />cfs <br />" <br />1996 <br />0.015 <br />cfs <br />" <br />1995 <br />0.015 <br />cfs <br />" <br />1994 <br />no flow <br />(very low <br />snowpack runoff this year) <br />1993 <br />0.114 <br />cfs <br />(pond was dewatered to repair a leaking <br />dewatering <br />line) <br />17 <br />
