While it is obvious that there is a general downhill trend from the upper <br />end of the ditch to its terminus, it is not readily apparent whether there are knick points or pool <br />areas along the run of the ditch. We previously identified the following potential pooling points in <br />the October 8, 2013 survey (numbers in red). <br />Station <br />Elevation <br />0 +00 <br />7718.83 <br />1 +00 <br />7718.83 <br />1 +01.92 <br />7718.824 <br />2 +00 <br />7718.56 <br />2 +29.59 <br />7718.452 <br />3 +00 <br />7720 <br />3 +32.25 <br />7720.888 <br />4 +00 <br />7718.6 <br />5 +00 <br />7718.92 <br />5 +79.87 <br />7719.174 <br />6 +00 <br />7719.32 <br />6 +80.08 <br />7719.002 <br />7 +00 <br />7721.29 <br />8 +00 <br />7719.56 <br />8 +03.57 <br />7719.491 <br />Station <br />Elevation <br />9 +00 <br />7719.42 <br />9 +26.67 <br />7719.745 <br />10 +00 <br />7720.06 <br />11 +00 <br />7724.01 <br />11 +03.71 <br />7724.166 <br />12 +00 <br />7724.52 <br />12 +11.45 <br />7724.96 <br />13 +00 <br />7730.19 <br />13 +83.58 <br />7731.334 <br />14 +00 <br />7729.38 <br />15 +00 <br />7730.95 <br />15 +02.85 <br />7730.999 <br />16 +00 <br />7732.51 <br />17 +00 <br />7734.92 <br />17 +44.19 <br />7736.838 <br />Station <br />Elevation <br />18 +00 <br />7736.08 <br />18 +44.49 <br />7737.311 <br />19 +00 <br />7739.03 <br />19 +85.13 <br />7743.16 <br />20 +00 <br />7743.42 <br />21 +00 <br />7745.63 <br />21 +15.56 <br />7745.295 <br />22 +00 <br />7751.05 <br />22 +45.95 <br />7754.661 <br />23 +00 <br />7756.58 <br />23 +46.45 <br />7756.175 <br />24 +00 <br />7757.13 <br />24 +79.80 <br />7762.701 <br />25 +00 <br />7763.06 <br />34 +51.31 / 30 +36.5 <br />7722.597 <br />A comparison of the January 2014 and October 2013 surveys indicates that, for the most part, the <br />areas of concern previously identified did not get resurveyed.
