Glen Canyon Dam: FAQ

Where is Glen Canyon Dam?
In Coconino County, Arizona (AZ). The map on this page is placed at the coordinates EIA files for the plant, which locate the site rather than any individual unit.
How big is Glen Canyon Dam?
1 GW of nameplate capacity across 8 units, as of the EIA-860M release for 2026-07.
Who owns Glen Canyon Dam?
EIA-860M names U S Bureau of Reclamation as the reporting entity. That is the operator of record on the survey, which is not always the ultimate owner.
Is this the same as Glen Canyon Dam LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — U S Bureau of Reclamation here — not the project company that holds the asset. Project companies are commonly registered as an LLC carrying the plant's name, so a search for "Glen Canyon Dam LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Glen Canyon Dam still running?
