Glen Canyon Dam

The Glen Canyon Dam spans 475 meters across the Colorado River and rises 216 meters high, creating Lake Powell, a major water reservoir.

The Bureau of Reclamation constructed the dam between 1956 and 1966 for $135 million to manage water distribution between Upper and Lower Colorado River Basins.

The dam's construction submerged numerous Native American archaeological sites and changed the traditional way of life for local indigenous communities.

The facility generates over 4 billion kilowatt-hours of hydroelectric power annually, supplying electricity to approximately 5 million customers across western states.

The dam's water releases maintain specific temperatures and flow patterns that have created a specialized ecosystem for rainbow trout below the structure.
