Mackenzie Reservoir storage in context

Mackenzie Reservoir water level, past 12 months

10.8% full at the latest reading - across the past 12 months it ranged from 10.8% (October 24, 2026) to 13.0% (October 25, 2025). Percent full is storage against the 46,450-acre-foot capacity basis, not a share of the elevation plotted above.

Mackenzie Reservoir elevation, full record

10.8% full at the latest reading - across the storage record since April 17, 1999 it ranged from 4.7% (May 21, 2014) to 21.5% (May 31, 1999). Percent full is storage against the 46,450-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.
