<br />The ditch structure will consist of two new radial gates. <br />Each radial gate will be 10 feet wide and 5 feet high. The <br />gates will be built with a common concrete headwall. This <br />headwall will protect the gates during times of high river <br />flow. <br /> <br />These features are shown in the preliminary set of plans found in <br />Appendix B. <br /> <br />. <br /> <br />Water Riqhts <br /> <br />There are 88 shareholders in the SIC with rights to divert 113.9 <br />cfs from the South Platte River under a river call of July 1873. <br />The SIC decree was adjudicated November 15, 1894 and was <br />appropriated July 15, 1873. The official name on the decree is <br />STERLING IRRIGATION COMPANY DITCH 1. <br /> <br />. <br /> <br />The SIC diverted a total of 16,107 acre feet in 1995, 18,971 acre <br />feet in 1996, and 18,943 acre feet in 1997, according to State <br />Engineer records. The average diversion for the past 48 years is <br />23,563 acre feet. Yearly diversions for the SIC would be <br />considered inconsistent. The main reason for this inconsistency <br />is that in years when the sand dam washed out sufficient amounts <br />of water can not be diverted. The S.E.O. diversion records are <br />found in Appendix C. <br /> <br />Cost Estimate <br /> <br />. <br /> <br />The estimated total project cost is $358,981.
