Lake Powell’s depth varies across the reservoir and over time, but here are the key figures often cited:
- Maximum depth (near the Glen Canyon Dam): about 560–583 feet (roughly 170–178 meters) when the lake is near full. This corresponds to full pool conditions, typically around an elevation near 3,700 feet above sea level.
- Average (mean) depth: around 132 feet (about 40 meters). This is a commonly cited figure for the overall lake, reflecting the broad, deep canyons interspersed with shallower sections.
- Current depth (at the dam) and level: depth at the dam and water elevation are highly seasonal and depend on inflows, releases, and drought conditions. In recent years, the reservoir has dropped well below full pool, and depths at the dam have been reported in the range well under 200 feet, with the lake surface several hundred feet below full. For example, during drought periods, headlines and data sources have noted depths around the 150–180 foot range at the dam, though exact numbers shift day to day.
If you need a precise, up-to-date depth at a specific location on Lake Powell (for example, at the dam, a particular marina, or a known cove), I can look up the latest figures from official water data sources and provide a current value and the surrounding context (water elevation, volume, and inflow/outflow trends).
