<br />Carpenter & Mitchell Ditch Company <br />May 16, 2005 (Revised May 31,2005) <br />Page 2 of 4 <br /> <br />Agenda Item 15c <br /> <br />, <br />informational brochures, funding coordination, project management and Ilegal 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 />Feasibilitv Study <br /> <br />Eldon Simmons, Company President has completed the feasibility stud~ in accordance with CWCB <br />guidelines. The study includes an assessment of alternatives available fpr ditch rehabilitation. The <br />cost estimate is provided by NRCS. Raymond Keith ofthe Mancos Con$ervation District continues to <br />provide guidance and coordination on salinity projects in the valley. <br /> <br />The members of the Company own the water rights conveyed in the Ditch. The source of the irrigation <br />water is Chicken Creek (a tributary to the Mancos River). An open ditchl currently carries the 11.25 cfs <br />and an average of 756 acre-feet per year (measured 1974-2002 per St~te Engineer's Office Summary), <br />with the highest diversion measured in 1987 of 1,161 ac-ft. The 11.25 cis is diverted from Chicken <br />Creek at diversion structure No. 508 under 12 different adjudicated right.s with datesof appropriation <br />ranging from 1878 to 1890. In addition, five rights to storage water in Ja,ckson Gulch Reservoir are used <br />to supplement adjudicated rights late in the irrigation season. I <br /> <br />Proiect Descriotion <br /> <br />Three alternatives were analyzed in the feasibility study: <br /> <br />1) No action alternative I <br />2) Individual members construct pipeline to meet their own needs hi <br />3) Participate in the Mancos Valley Unit of the Colorado River Basi. Salinity Control Program <br />I <br /> <br />The Company chose to participate in the Salinity Control Programprim$rily due to the available NRCS <br />funding assistance. The selected alternative includes a new diversion structure, flow rate measurement <br />structure, approximately 13,000 feet of PVC pipeline, metered delivery points to each member, valves, <br />drains and vents, and river channel improvements to improve delivery qf the water to the diversion <br />structure. I <br /> <br />Total Project cost estimate is: <br /> <br />TOTAL <br /> <br />$1 01,200 (~O% of Const. Cost) <br />506.000 <br />$607,200 <br /> <br />1. <br />2. <br /> <br />Planning/Engineering <br />Construction <br />
