Water - levels overall were fairly similar the last few years -in well-GF4. Mining occurred south of <br />well -GF4 in the early 1980's and is expected to limit-water-level changes in the HI aquifer near well <br />GF4. Water revels in the upgradient unconfined backfill aquifer do not -fluctuate -as -much -as-the <br />confined HI aquifer. The backfill aquifer may prevent the low recharge year from affecting the water <br />level down gradient in the HI aquifer. It is also possible that the backfill spring in Johnson Gulch <br />may be limiting the head in the backfill aquifer. <br />Wells GF -6 and GF -11 are completed in the QR aquifer and QR backfill, respectively. <br />Backfill well GF -11 is located on the downgradient side of the inactive F pit, while well GF 6 is <br />located downgradient of-the pit. GF -11 is 1150 feet upslope and upgradient of GF -6. Overall <br />increases in water levels were observed in wells GF -6 and GF -11 for 2008 with similar but smaller <br />seasonal- changes observed- in 2009 and_ 2010 (see Figure A-6). Large seasonal changes_ were <br />observed. in 2011 with overall higher water levels. Water levels in the backfill well overall declined <br />in 2012 and 2013 while the levels were steady down gradient in the QR aquifer. The head in well <br />GF -11 is approximately 15 feet above the head in well GF -6. The water levels in the backfill aquifer <br />may be near fully recovered from mining but have been much more variable the last six years. <br />Figure A -7 presents water levels for -GN7 and -GN8, which are - located very near- the <br />eastern boundary of the PA. They are completed in the KLM and HI aquifers and may provide <br />undisturbed baseline data for these intervals-but could be- influenced by mining- for - the -last few years. <br />Water levels in well - GP -7 overall have been steady for -the last few years. A slight increase was <br />observed-in 2010 and 2011-in-well GP4 after 3-years -of steady -water levels from 2007 through 2009. <br />Water -levels in both of these wells very gradually declined in 2012 -and 2013 and are thought to be <br />showing natural responses but could be influenced by the mining that is greater than 1900 feet away. <br />Well GP -2 (Figure A -8) is located in a previously undisturbed area near the eastern <br />boundary of the PA. Water levels rose in 2008 through 2011 in well GP -2 to a similar level as <br />Trapper Mining Company 2 -6 <br />2013 Annual Report <br />
