aquifer is northerly, similar to that observed in 2011 (see Hydro- Engineering, 2012). The <br />ground -water gradient between the backfill aquifer and the un -mined HI aquifer downgradient is <br />relatively flat as it is in the QR backfill. The contours in the HI aquifer have also been changed on <br />the east side where previous mining in the A pit has likely caused water level declines near this pit. <br />The D and K pits were used to mine the I seam and the K pit also mined the H and I seams in 2010 <br />through 2012. The H seam was not mined in 2009. <br />The 3rd White Sandstone aquifer water -level elevations are presented on Map No. 2 -3. <br />Wells GC -2, P -8 and GP -9 were used in the development of this map. Flow direction in the 3rd <br />White Sandstone is mainly toward the north, as expected. The 2012 contours are very similar to <br />those observed from the last few years. <br />Trapper Mining Company 2 -10 <br />2012 Annual Report <br />
