Retreat mining of D seam ended under the Bear Creek drainage during 2008. The status of the <br />Bear Creek road is assessed as part of ongoing subsidence monitoring. No adverse effects as a <br />result of mining activities (or the multitude of other uses) were observed to have occurred to the <br />Bear Creek road or Bear Creek water quality in 2014. From a historical perspective it is <br />important to remember that, in addition to all of the surface uses of the Bear Creek drainage, the <br />Bear Creek drainage was also undermined by extensive historic mine workings in the B and C <br />seam of the Somerset Mine. <br />B -2 and B -3 -- In accordance with the Elk Creek Federal Coal Lease COC -61357 <br />"Water Replacement Plan" stipulation, surface water monitoring points B -2 and B -3 are <br />monitored for flow twice annually after tributary flow from side channels between the two points <br />has ceased. B -2 corresponds to a mid -Bear creek location roughly corresponding to the south <br />limit of the Elk Creek Federal Coal Lease. B -3 corresponds to an upper Bear Creek location <br />roughly corresponding to the north limit of the Elk Creek Federal Coal Lease. Generally, due to <br />the ephemeral nature of Bear Creek and the propensity for flows to quickly cease by late June, <br />flow measurements are most often obtained in mid -June. <br />BEAR CREEK FLOW INFORMATION <br />Date Site B -2 Site B -3 <br />June 10, 2003 <br />0.25 cfs <br />0.21 cfs <br />June 16, 2003 <br />0.097 cfs <br />0.088 cfs <br />June 15, 2004 <br />0.02 cfs <br />0.041 cfs <br />June 22, 2004 <br />0.0 cfs <br />0.0174 cfs <br />June 15, 2005 <br />1.036 cfs <br />1.085 cfs <br />June 30, 2005 <br />0.39 cfs <br />0.13 cfs <br />June 7, 2006 <br />0.047 cfs <br />0.033 cfs <br />June 13, 2006 <br />Trace flow <br />Trace flow <br />June 15, 2007 <br />0.21 cfs <br />0.34 cfs <br />June 28, 2007 <br />Trace flow <br />Trace flow <br />June 18, 2008 <br />1.29.cfs <br />0.72 cfs <br />June 25, 2008 <br />0.49 cfs <br />0.67 cfs <br />June 17, 2009 <br />0.55 cfs <br />0.46 cfs <br />June 25, 2009 <br />0.65 cfs <br />0.63 cfs <br />June 4, 2010 <br />3.3 cfs <br />1.5 cfs <br />June 11, 2010 <br />0.67 cfs <br />0.67 cfs <br />June 14, 2011 <br />2.3 cfs <br />1.85 cfs <br />June 28, 2011 <br />1.35 cfs <br />1.92 cfs <br />June 8, 2012 <br />0.0 cfs <br />0.0 cfs <br />June 13, 2012 <br />0.0 cfs <br />0.0 cfs <br />June 3, 2013 <br />0.257 cfs <br />0.22 cfs <br />June 24, 2013 <br />0.0 cfs <br />0.0 cfs <br />June 12, 2014 <br />0.5 cfs <br />0.63 cfs <br />June 17, 2014 <br />0.42 cfs <br />0.12 cfs <br />7 <br />
