The Glen Canyon Dam is a hydroelectric dam on the Colorado River in Page, Arizona. It forms Lake Powell, and provides both electricity and irrigation to the Southwestern region of the United States. The dam's construction was controversial because of the environmental damage it was expected to cause.

The Glen Canyon Dam's obstruction of the Colorado River altered the environment downstream. On March 5, 2008 the dam was used to create an artificial flood in the Grand Canyon. The flood was intended to flush out the area and revitalize river-side ecosystems.
