water -level elevations. Table A -1 in Appendix A presents a tabulation of the water -level elevations <br />-for each of the monitoring wells. Figure 2 -1 presents the total annual precipitation at the Trapper <br />Mine - rom 1978-through 2013. Precipitation declined from a high in 1983 to a low in 1988 and had <br />increased again to a peak in 1993 with a below average value in 1994. The years 1995 through 1997 <br />had above average -precipitation relative to the Trapper -Mine record, while 1998 through 2004 were <br />below. The precipitation in 2005 through 2011 was above or near normal while precipitation in 2012 <br />was slightly below the 1088, 1904 and 2002 low precipitation years and 2013 precipitation was equal <br />to the Trapper Mine average. Water levels in many of the wells reflect the natural variations in <br />recharge. These changes may lag the actual precipitation events due to the time it takes the head <br />change to move through the aquifer to the monitoring well. <br />Figure A -1 presents water levels versus time for wells GF -5 and P -5. The wells are <br />completed in the HI backfill and 2nd White Sandstone aquifers, respectively. Water levels in well <br />GF -5 slightly rose in 2007. and 2008 and were steady in 2009 and 2010 and a small overall rise in <br />2011 and decline in 2012 and 2013. Well P -5 went from being dry in early 2010 to recovering four <br />feet in late 2010 and 2011 but was -dry in 2012 and 2013 except for the -4th quarter in each of these <br />years. <br />The GC wells (GC -1, GC -2, GC -3, see Figure A -2) are located near the northeast corner <br />of the permit area- (PA-) slightly more than 1 -100 feet from mining activity in 2013. These wells are <br />completed in the- HI, 3rd White and - alluvial- aquifers, respectively. The water -level changes in- these <br />-wells -may -not still be -good -indicators of natural recharge impacts on these aquifers due to the <br />upgradient mining. Water levels in well GC -1 have been overall steady from 2003 to 2009. In 2010 <br />and 2011 the water level rose while a decline was observed in 2012 and 2013. Water levels in well <br />GC -3- show some seasonal effects. Water levels in well GC -2 were overall steady from 1999 to <br />2005, while gradually increasing 2006 through 2011 prior to becoming steady in 2012 and 2013. <br />Trapper Mining Company 2-4 <br />2013 Annual Report <br />
