(please see attached project description <br />and map.) <br /> <br />Backeround <br />This study and project are of regional concern. The purpose of this study is to evaluate the <br />need and possible corrective measures necessary for the District's power canal. The power canal <br />delivers approximately 860 c.f.s. of Colorado River water to the 9,400 acres of irrigated land on the <br />east orchard mesa and orchard mesa in the Grand Valley. Water is diverted by the Grand Valley <br />Water Users Association at the Government Highline Canal roller dam in the DeBeque Canyon on <br />the Colorado River, brought via tunnels constructed over 100 years ago approximately 3 miles to the <br />District's diversion point near the siphon under the Colorado River. The canal walls that traverse the <br />canyon above Interstate-70 are deteriorating and are in need of rehabilitation. The walls are also too <br />low in some areas to handle the full water right available for wintertime power generation. There <br />have been occasions when ice forms in the winter causing the canal to overtop and flood the interstate <br />creating an ice hazard to motorists. <br /> <br />Flood Protection.
