Construction must begin <br />November 1, 2006, with completion no later than March 25,2007. It is anticipated that <br />actual construction would be complete in less than two months to allow the District to <br />resume production at the hydroelectric plant that is a source of revenue for Xcel Energy, <br />Grand Valley Water Users Association and the Orchard Mesa Irrigation District. The <br />loss of that revenue (an average of $80,000) during construction is a significant portion of <br />the OMID budget. <br /> <br />Orchard Mesa Irrigation District Feasibility Study <br />Stokes Gulch Siphon <br /> <br />Page 10 <br />
