. . . Feasibility Study Silt Diversion-Colorado River Diversion Project Introduction (Need for the Project) The Silt Diversion-Colorado River Diversion project is located on the Grand River Canal east of Silt, Colorado approximately 1 and 1/2 miles, in the northwest quarter of section 12, Township 5 South, Range 92 West, as shown on the location maps on pages 10 and 1 Oil, The ditch is owned and operated by the Silt Water Conservancy District. The existing diversion in the river carries water to a pumping station and consists of an earthen and gravel embankment that extends 600 feet into the Colorado River. The structure is very vulnerable to seasonal flooding and is rebuilt on an annual basis, It is proposed that this system is replaced with a concrete, rock diversion and headgate structure in a side channel approximately 1,000 feet upstream from the present point of diversion to a more manageable location, The water will be conveyed in 940 feet of 42" HDPE low head irrigation pipe carrying 40 cubic feet of irrigation water back to the original ditch system, The new diversion will use current technology to reduce habitat loss, to increase river stability, to improve aquatic habitat, and improve riverbank vegetation, The new diversion will illustrate an alternative to the old system of having to annually enter the river, which created damage to the river system. Benefits achieved from the installation of the new structure could be a point of interest since the sire is easily accessible from 1-70, The Silt Conservancy District has spent a considerable amount of money in the past few years repairing and replacing structures in their system. Project Sponsor The Silt Water Conservancy District was incorporated September 23,1907 for the purposes of: (I) managing the ditch for the landowners whose properties are irrigated from the ditch, and (2) maintaining, repairing and, when necessary, reconstructing the ditch, Dues are assessed based on pro-rated ownership or use of water rights in the ditch, Under the by-laws of the Corporation, "No loans shall be contracted on behalf ofthe Corporation,., unless authorized by the Board of Directors.
