water -level plots according to aquifer where possible but, in most cases, are grouped by similar <br />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 from 1978 through 2014. 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 1988, 1994 and 2002 low precipitation years and 2013 precipitation was equal <br />to the Trapper Mine average while 2014 was slightly above. Water levels in many of the wells reflect <br />the natural variations in recharge. These changes may lag the actual precipitation events due to the <br />time it takes the head 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 through 2014. Well P -5 went from being dry in early 2010 to recovering <br />four feet in late 2010 and 2011 but was dry in 2012 and 2013 except for the 4th quarter in each of <br />these years and three quarter in 2014. <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 1100 feet from mining activity in 2014. 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 through 2014. Water levels in <br />well GC -3 show some seasonal effects. Water levels in well GC -2 were overall steady from 1999 to <br />Trapper Mining Company 24 <br />2014 Annual Report <br />
