• It is interesting to note that on August 5, 1982, three successive <br />flow measurements were made on Middle Thompson Creek. The measure- <br />ments were taken at the upstream site, just below the "A" seam coal <br />outcrop, and at the downstream site, the flows were 12.4 cfs, 12.8 <br />cfs, and 9.1 cfs respectively. This seems to suggest that the water <br />loss is occurring somewhere between the coal seams and the downstream <br />site. <br />Table 3.6.1-13 Flow Values and Differences (cubic feet <br />per second) on Middle Thompson Creek <br />SITE <br />DATE UPSTREAM DOWNSTREAM DIFFERENCE PERCENT CHANGE <br /> <br />6/17/81 24,40 16.26 -8.14 33 <br />• 7/16/81 13.65 10.29 -3.36 25 <br />8/17/81 3,12 2.62 -0.50 16 <br />9/02/81 2.16 1.85 -0.31 18 <br />10/15/81 2.85 2.47 -0.38 14 <br />11/09/81 3.17 3.22 -0.55 16 <br />12/18/81 1.97 1.82 -0.15 10 <br />1/15/62 1.70 1.70 0.00 0 <br />2/25/82 (1) (1) - - <br />3/31l82 (1) (1) - - <br />4/27/82 21.35 19.27 -2.08 10 <br />5/27/82 37.34 33.50 -3.84 10 <br />(1) Flow unobtainable due to severe icing. <br />Source: Snowmass Coal Company. <br />3-72 <br />
