• Lake Mohave is 87.7% full - high on this site's capacity scale - as of October 21, 2026. Surface elevation 638.85 feet, storage 1,643,680 acre-feet (capacity basis 1,873,648 acre-feet), per U.S. Bureau of Reclamation gauge data.
• That elevation is 16.75 feet above its record low of 622.10 ft (September 7, 1953, 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 113% of the October 21 average across 77 years of record.
• Lake Mohave is falling: elevation changed -0.12 ft over the past week, -0.03 ft over the past month, and +0.81 ft over the past year, per U.S. Bureau of Reclamation gauge data.

Lake Mohave has held roughly steady over the past twelve months (+0.81 ft in surface elevation).

Lake Mohave storage in context

Lake Mohave water level, past 12 months

87.7% full at the latest reading - across the past 12 months it ranged from 85.6% (October 4, 2026) 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

87.7% 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.
