<br />" <br /> <br />Mancos Valley Beaver Ditch Company <br />September 7, 2004 <br />Page 2 014 <br /> <br />Agenda Item 4a <br /> <br />and several others in the Mancos Valley. Qualifying agriculture producers that install more efficient <br />irrigation systems, which reduce salt loadings may be eligible for funding by the EQIP. <br /> <br />Feasibility Study <br /> <br />Raymond Keith, Mancos Conservation District, has completed the feasibility study in accordance with <br />CWCB guidelines. The study includes an assessment of alternatives available for ditch rehabilitation. <br />The cost estimate is provided by NRCS. <br /> <br />. <br /> <br />The Mancos Valley Beaver Ditch Company <br /> <br />The Company isa non-profit corporation registered in the State of Colorado in July 2003 and is in good <br />standing. There are four (4) Company members. The Company is relatively new, however the Ditch has <br />been in existence for nearly 126 years. Prior to incorporation, an informal version of the Company <br />managed the Ditch by distributing costs or in-kind services for Ditch maintenance and repair needs <br />(approximately $800 per year). Future member assessments will be based on a prorated amount of <br />adjudicated water rights owned by each member and conveyed through the Ditch. The Company's <br />Funding Agreement establishes the proportioned amount for each member. The Company will own, <br />operate and maintain the new pipe system and diversion structure and will have the responsibility to <br />receive, convey and deliver irrigation water to the members of the Company. The Company will repair, <br />improve and/or reconstruct the Ditch when necessary. The Company does not own any of the water <br />conveyed in the Ditch. <br /> <br />Water Riahts <br /> <br />. <br /> <br />The members of the Company own the water rights conveyed in the Ditch. The source of the irrigation <br />water is the Mancos River. An open ditch currently carries the 10.49 cfs and an average of 1,431 acre- <br />feet per year (measured 1974-2002 per State Engineer's Office Summary), with the highest diversion <br />measured in 1982 of 2,493 ac-ft. The water 10.49 cfs of diverted at diversion structure No. 505 consists <br />of 16 different adjudicated rights with dates of appropriations ranging from 1878 to 1891. In addition, <br />four (4) rights to storage water in Jackson Gulch Reservoir are used to supplement adjudicated rights <br />late in the irrigation season. <br /> <br />Proiect Description <br /> <br />Three alternatives were analyzed in the feasibility study: <br /> <br />1) No action alternative <br />2) Individual members construct pipeline to meet their own needs <br />3) Participate in the Mancos Valley Unit of the Colorado River Basin Salinity Control Program <br /> <br />The Company chose to participate in the Salinity Control Program primarily due to the available NRCS <br />funding assistance. The selected alternative includes a new diversion structure, flow rate measurement <br />structure; dual PVC pipeline for first 4,190 feet of ditch, approximately 20,100 feet of single PVC <br />pipeline, metered delivery points to each member, valves, drains and vents, and river channel <br />improvements to improve delivery of the water to the diversion structure. <br /> <br />Total Project cost estimate is: <br /> <br />TOTAL <br /> <br />$123,900 (30% of Cons!. Cost) <br />413.000 <br />$536,900 <br /> <br />. <br /> <br />1. Planning/Engineering (NRCS In-Kind) <br />2. Construction <br />
