The nearly four mile ditch is a carriage ditch <br />diverting water for irrigation purposes from McElmo Creek at a peak rate of 7.75 cfs, for an annual <br />average of 1,003 acre-feet. Construction of the ditch commenced in 1889 and the current ditch and <br />diversion structure are in need of rehabilitation. This project was responsible for the installation of nearly <br />four miles of PVC pipeline (15"/21" diameter), including valves, drains, vents and metered delivery <br />points; construction of a new diversion structure; and channel improvements. In doing so, this project <br />increased the efficiency of the ditch while reducing salinity impacts in the Colorado River, thereby <br />qualifying for a grant from the Natural Resources Conservation Service (NRCS) in the amount of <br />$391,000. <br />Project Data <br />Sponsor: Black Dike Pipeline County: Cortez Water Source: McElmo Creek <br />Company <br />Terms of Loan: $207,000 (initially $598,000), Substantial Completion Date: 10-1-2008 <br />over 30 years @ 2.85% <br />Design Engineer: Harward Irrigation Systems Inc., Springville, UT <br />Construction Contractor: Harward Irrigation Systems Inc., Springville, UT <br />Lewis Excavation, Mancos, CO <br />Construction Elements: * Installation of 20,000 LF of PVC piping (15"/21" diam.) <br />* metered delivery points * construction of a new diversion structure <br />:. ..� . <br />� <br />r: <br />�• .; <br />.. ) '�, t �� •,T. - , <br />� 4��i �� � � .� <br />.. � A 5fi: K t � 1�� ,. <br />i3 � , <br />} ` i rn i�,i � _' <br />�H T � A ! <br />Average Annual Diversion: 1,003 acre-feet <br />
