Figure 2. Canon City, Colorado long -term average snowfall (1892 -93 — 2012 -13) is compared with the <br />yearly snowfall data for the winters of 1998 -99 — 2012 -13.10 <br />The precipitation in the area is variable. It was variable over the past five years and it was variable <br />prior to those years as well. The snowfall for 2008 -2009 was below average, while the overall <br />precipitation for 2009 was above average by nearly four inches. Snowfall for 2010 -2011 and 2012 -2013 <br />was also below average; precipitation for 2011 was below average and it is unknown what the total <br />precipitation for 2013 was as values for the months of April- August of 2013 are missing. Snowfall for <br />2009 -2010 and 2011 -2012 was above average; however, 2010 and 2012 total precipitation was below <br />average. <br />The City of Florence has first call on 5 cfs of Newlin Creek water which is collected and diverted <br />upstream from NC 2.111t is possible that Newlin Creek will never run again across our land or it could be <br />a full stream in future years, but here is another possibility for demonstrating the loss of flow. If the City <br />of Florence would cease the intake of water for perhaps 24 to 48 hours, there should be enough <br />downstream flow to demonstrate the water loss phenomenon. <br />I believe that (one) the subsidence monitoring has shown that pillared panels have subsided which has <br />affected Newlin Creek, that (two) thereis not a very deep alluvium foyer in the flowline of Newlin Creek, <br />and that (three) water flow in Newlin Creek has been reduced in the past five years as a result of <br />percolating through the fractured overburden and entering the voids of the underground mines. <br />REFERENCES <br />1.
