Constructed on the Colorado River in Arizona near the town Page in 1966, the Glen Canyon Dam is a concrete arch dam that provides hydroelectricity and flow regulation from the upper Colorado River Basin to the lower. The creation of the dam has tamed the waters of the Colorado River considerably and has formed Lake Powell (186 mi long), the second largest reservoir in the U.S. By suppressing floods and other factors that once characterized the Colorado, the dam has led to major physical and ecological changes in the lower river. Currently, Lake Powell’s reservoir is less than half full as a result of a 14-year dry run.
This engineering marvel was recognized by the American Society of Civil Engineers during the National Competition in 1964 for outstanding achievement in civil engineering.
