Lake Mead vs Its Record Low

Tracked daily from the Bureau of Reclamation gauge the record was set on — measured levels and Reclamation's published projections, no forecasts of our own.

Western Reservoir Conditions·Daily·No. 6··Latest reading

No level in Lake Mead's daily record since it first filled has been lower than the 1,040.58 feet reached on July 28, 2022. This page measures the distance to that line every day, from the same Bureau of Reclamation gauge the record was set on — no forecasts of our own, just the measured approach.

2026 against 2022, day by day

2022 is the year the standing record was set. The chart lays 2026's daily elevations over 2022's by calendar day — the 2022 line bottoms out at 1,040.58 ft in late July before autumn releases from Lake Powell stabilised it.

Lowest annual minimums on record

Each year's single lowest daily reading — the ten lowest years in the post-fill record, lowest first. The all-time record low is row 1 by definition.

What a new record would — and would not — change

Nothing operational is keyed to the record-low number itself. Lower Basin shortage operations are set annually from Reclamation's projected January 1 Lake Mead elevation against the fixed shortage-tier thresholds (1,075 / 1,050 / 1,025 ft), and the physical floors are minimum power pool (950 ft, where Hoover Dam's turbines stop) and dead pool (895 ft, below which water cannot pass the dam by gravity). As of the lake is 91.1 ft above minimum power pool and 146.1 ft above dead pool. A record low is a milestone of the drought, not a switch — the operating decisions ride the tiers, and the rules themselves are being replaced for 2027 (post-2026 guidelines).
