Check the latest officially reported lake level, daily changes, storage and long-term trends.
Height scale only — not the percentage of water stored.
Official daily records may be revised. How our data is collected ↗
Water level tells you the lake's height. Here, see how much water it holds and how that amount is changing.
of the lake's published reference capacity
That's 5.28 million acre-feet of stored water.
As of Oct 17, 2026 · Official daily measurement
We compare the officially reported stored water with the published 24.322 million acre-feet reference maximum ↗. This is not the agency's separately defined live-capacity percentage.
Storage data is temporarily unavailable. Please check the official records.

Explore official daily water levels over the past week, month or year.
See the current water level, critical thresholds, and how far Lake Powell is from each one.
See how the latest water level compares with the lake's critical elevations.
This scale shows water height, not percent of reservoir capacity. All elevations use NGVD29.
Approx. depth at dam is the water-level elevation minus the dam's original riverbed elevation (3,132 ft); it is not a direct measurement of today's underwater depth. Official dam specifications ↗

View level history →The level shown above is an elevation, not a storage percentage. The storage section above provides the latest reported amount of water in acre-feet, with a date and reference-capacity comparison. A linear position on the elevation scale cannot be converted directly into storage volume.
Use the 7-day and 30-day changes above. These comparisons use daily observations, not minute-by-minute measurements.
Water level and stored water come from official daily reservoir records. They can be published on different dates, so always check the date shown next to each figure. All water elevations use NGVD29.
