Davis Dam · Colorado River · Nevada / Arizona - updated daily from official gauges
Western Reservoir Conditions·Daily·No. 45··Latest reading
- Lake Mohave is 90.8% full - high on this site's capacity scale - as of . Surface elevation 640.96 feet, storage 1,702,080 acre-feet (capacity basis 1,873,648 acre-feet), per U.S. Bureau of Reclamation gauge data.
- That elevation is 18.86 feet above its record low of 622.10 ft (, the lowest since the reservoir first filled), in a daily record going back to January 8, 1950 (Reclamation's period of record for this daily series).
- Storage is 111% of the September 5 average across 77 years of record.
- Lake Mohave is falling: elevation changed -1.98 ft over the past week, -1.84 ft over the past month, and -1.81 ft over the past year, per U.S. Bureau of Reclamation gauge data.
Lake Mohave is holding near the top of its operating range at 90.8% of capacity, -1.81 ft over the past twelve months.
Lake Mohave operating range
Lake Mohave is operated within a narrow band rather than drawn down and refilled over years. As of it sits 6.04 feet below its 647.0 ft full-pool reference. Over the past two years the daily record ranges from 634.97 ft () to 644.37 ft () - a band of 9.39 feet. The highest reading in the full record is 646.95 ft on .
Storage above the full-pool reference is flood control space, not supply. A reservoir reading at or near 100% of its conservation capacity is being operated normally - it is not a surplus, and the operator may release water to hold that space.

Lake Mohave water level, past 12 months
90.8% full at the latest reading - across the past 12 months it ranged from 85.0% (September 15, 2025) to 95.8% (May 17, 2026). Percent full is storage against the 1,873,648-acre-foot capacity basis, not a share of the elevation plotted above.
Lake Mohave elevation, full record
90.8% full at the latest reading - across the storage record since February 2, 1950 it ranged from 0.1% (December 2, 2006) to 96.5% (May 29, 1963). Percent full is storage against the 1,873,648-acre-foot capacity basis, not a share of the elevation plotted above. Every percentage here is measured against today's capacity basis; a reservoir's surveyed capacity changes as sediment accumulates behind the dam, so early-record percentages are indicative rather than exact.

Notes
- 1/Percent full is storage divided by the 1,873,648 acre-foot capacity basis published in the USBR Lower Colorado River Daily Report. ↩
- 2/Elevations are from Bureau of Reclamation RISE daily series item 6133 (storage item 6134) for Davis Dam. Reclamation publishes these as provisional and may revise them. ↩
- 3/Gauge coordinates 35.1979, -114.5694 - USBR RISE location 3513. Elevations are as published by the operating agency; consult the source for the vertical datum in use. ↩
- 4/Period of record for the daily series used here begins January 8, 1950 (Reclamation's period of record for this daily series). Record low is measured over that window only. ↩
- 5/All readings carry the date the gauge reported them, which may lag today's date. This site publishes observations, not forecasts. ↩
