The day before we left Wahweap to explore the canyons of Lake Powell we thought it would be appropriate to visit the dam which created the lake we are soon to boat in. We signed up for the tour and learned a lot about the construction and purpose of the dam.
Glen Canyon Dam is a concrete arch dam on the Colorado River in northern Arizona in the United States, just north of Page. The dam was built to provide hydroelectricity and flow regulation from the upper Colorado River Basin to the lower. Its reservoir is called Lake Powell, and is the second largest artificial lake in the country, extending upriver well into Utah. The dam is named for Glen Canyon, a colorful series of gorges most of which now lies under the reservoir.
