<br />" <br /> <br />Hydrology and Water Rights <br /> <br />The source of water for the Company is direct flow water rights out of Alamosa Creek. <br />The water rights diverted at the EI Viejo headgate are priority number one in Water <br />District 21 with dates of appropriation ranging from 7-11-1888 and totaling 14.4 cfs. from <br />the State Engineer's Office indicate that total average annual diversions are 6026 acre- <br />Ofeet, based on record years 1991 through 2002, and that the maximum diversion rate <br />was 19 cfs for record years 1985, 1986 and 1995 <br /> <br />Project Description and Alternatives <br /> <br />The purpose of this project is to provide a means for the EI Viejo Ditch is to provide <br />irrigation water all water users while minimizing conveyance water losses, to update <br />turnout structures and installation of measuring weirs. <br />Five alternatives were considered: <br /> <br />1) The no-action alternative. <br />2) Removal of all trees within the ditch right-of-way. <br />3) Construct a concrete ditch <br />4) Grout existing channel <br />5) Replace parts of the open ditch with pipeline. <br /> <br />Alternative No. 1 was considered unacceptable since the EI Viejo ditch would still have <br />high ditch losses. <br /> <br />Alternative No.2 was ruled out because of environmental and community concerns <br />and it would not change the problem all that much. <br /> <br />Alternative No.3 & 4 were ruled out due to cost, the landowners desire to have the <br />ditch out of sight and out of the way and maintenance factors. <br /> <br />Alternative No.5 was selected, since it is offered the least maintenance, best <br />conveyance efficiency and the opportunity for energy savings with pipe pressure. <br /> <br />The selected alternative, Alternative No.5, involves the installation of two pipelines <br />with inlet and turnout structures, and measuring weirs. The Natural Resources <br />Conservation Service (NRCS-USDA) LaJara, Colo. Field Office will prepare engineering <br />designs and has cost estimates for the project. EQIP cost share contract plan as <br />prepared by the NRCS is attached to this study. <br /> <br />The estimated cost of the completed project is $220,029. The cost breakdown is <br />summarized in Table 1. The NRCS Preliminary Design report and detailed cost estimate <br />are included in Appendix D. <br />
