Originally constructed in <br />the 1920s, concrete is spalling off of the structure, leaving large areas of exposed <br />reinforcing. A failure during irrigation season could lead to a lengthy period without water <br />for irrigation needs. <br /> <br />This study will present a conceptual layout of a replacement inverted siphon at Stokes <br />Gulch, along with estimated costs of replacement. <br /> <br />1.2 Site description <br /> <br />The Orchard Mesa Power Canal is located near Palisade, Colorado. Before entering the <br />Orchard Mesa Power Canal, water from the Colorado River is diverted by the Grand <br />Valley Diversion Dam into the Government Highline Canal. An inverted siphon that <br />passes underneath the Colorado River delivers water from the Government Highline <br />Canal to the Orchard Mesa Power Canal. The Orchard Mesa Power Canal is <br />approximately 3.5 miles long and Figure 1.1 provides a site map. <br /> <br />Water that passes through the Orchard Mesa Power Canal is used for either power <br />generation or crop irrigation. Because the Power Canal is located at an elevation lower <br />than most of the lands it irrigates, water used for crop irrigation must be pumped. This <br />pumping is performed by the Orchard Mesa Pumping Station. A comprehensive and <br />detailed description of the operations of the Orchard Mesa Power Canal and the entire <br />Grand Valley Project may be found on the website www.usbr.Qov/html/Qrandvallev.html. <br /> <br />2616-R1 <br /> <br />Orchard Mesa Irrigation District <br /> <br />Water Management Consultants <br />
