level 182.5 ft below full pool — this gauge's public record is too short for seasonal comparisons

Is Lake Powell full?
Not quite — 182.5 ft below full pool as of September 23, 2026
How full is Lake Powell? Not as a percentage: no storage figure comes through with this gauge reading, and a share of capacity worked out from the elevation alone would be a guess — how much water a reservoir holds at a given level is a curve only the operator's own capacity table knows. Feet from full pool is what the operator publishes, and it is the figure above.
This year vs the years that matter
This year's trace against the finished years this gauge has published. Its public daily record begins in 2019, so the driest and wettest years are not named yet: that takes 8 finished years, and the lake regulars will remember wetter and drier years than any line here.

Full pool, datum, and the gauge
"Full pool" here means the conservation pool — the level the lake is designed to hold for water supply and recreation, not the flood-control space above it. The full explainer covers flood pool and dead pool too.
| Full pool | 3700.00 ft NGVD29 · per USBR Upper Colorado Basin Region full-pool reference |

| Datum | NGVD29 — Powell is quoted on NGVD29 here, the frame Reclamation's 3,700 ft full pool uses; the same gauge also publishes a NAVD88 figure that does not line up with it. |

LakeDates reports lake level, not ramp status. Whether a given ramp or marina is usable at this level varies ramp by ramp — call the marina before you tow.
