<br />East Mancos Highline Ditch Company <br />July122005 <br />Page 2 of 4 <br /> <br />Agenda Item 6c <br /> <br />i <br />I <br /> <br />this. Project. In addition, the Mancos Conservation District has providedllocal assistance by providing <br />informational brochures, funding coordination, project management an~ legal counsel for this project <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 />Regina Williams, Company Secretary-Treasurer, has completed the fe~sibility study in accordance with <br />CWCS guidelines, The study includes an assessment of alternatives-a~ailable for ditch rehabilitation. <br />The cost estimate is provided by Harward Irrigation. Raymond Keith of ~he Mancos Conservation <br />District continues to provide guidance and coordination on salinity projelcts in the valley. <br /> <br />The East Mancos Hiahline Ditch COmDany <br /> <br />The Company is a non-profit corporation registered in the State of Colc~rado in January 2004 and is in <br />good standing. There are six Company members. The Company is rel~tively new; however, the Ditch <br />has been in existence for 'nearly 126 years. Prior to incorporation, an i~formal version of t.he C.. ompany <br />managed the Ditch by distributing costs or in-kind services for Ditch mCfintenance and repair needs <br />(approximately $500 per year). The Company's Funding Agreement es~ablishes that member .-:~< <br />assessments will be shared equally. The Company will own, operate and maintain the new pipe system <br />and diversion structure and will have the responsibility to receive, convey and deliver irrigation water to <br />the members of the Company. The Company will repair, improve and/or reconstruct the Ditch when <br />necessary. The Company DOES NOT own any of the water conveyed In the Ditch. <br /> <br />Water Riahts <br /> <br />i <br />i <br /> <br />The members of the Company own the water rights conveyed in the Ditch. The source of the irrigation <br />water is the East Fork of the Mancos River. An open ditch currently ca~ries the 8.58 cfs and an average <br />of 619 acre-feet per year (measured 1974-20Q2 per State Engineer's Office Summary), with the highest <br />diversion measured in 1997 of 1,228 ac-ft. The 8.58 cfs is diverted from the East Fork of the Mancos <br />River at diversion structure No. 522 under 32 different adjudicated righ1s with dates of appropriation <br />ranging from 1878 to 1890. In addition, 250 AF of storage rights in Jac~son Gulch Reservoir are used <br />to supplement adjudicated rights late in the irrigation season. I <br /> <br />I <br /> <br />I <br />I <br />I <br /> <br />Proiect DescriDtion <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 i <br />3) Participate in the Mancos Valley Unit of the Colorado River Sasiin Salinity Control Program <br /> <br />The Company chose to participate in the Salinity Control Program pri~arilY due to the available NRCS . <br />funding assistance. The selected alternative includes a new diversion ~tructure, flow rate measurement <br />structure, approximately 30,385 feet of PVC pipeline, metered deliverylpoints to each member, valves, <br />I <br />drains and vents, and river channel improvements to improve delivery of the water to the diversion <br />structure. <br /> <br />Total Project cost estimate is: <br /> <br />TOTAL <br /> <br />$150,646 (~O% of Const. Cost) <br />753.354 i <br />$904,000 i <br /> <br />1. <br />2. <br /> <br />Planning/Engineering <br />Construction <br />
