Field notes
On Oct 25, 2026, Mackenzie Reservoir was at 3,018.29 ft, which is 10.8% of its conservation capacity.
That is 81.71 ft below the conservation (full) pool elevation of 3,100.00 ft.
Over the past 7 days the lake has been falling (−0.07 ft), and it is −0.32 ft over 30 days.
Compared with a year ago (3,022.80 ft), the lake is 4.51 ft lower.
For this time of year, the median in TWDB's records (1999–2025, 27 years with data) is 12.8% full, so Mackenzie is currently close to normal.
In TWDB's dataset (since 1999), the highest level recorded is 3,035.96 ft (May 31, 1999) and the lowest is 3,001.09 ft (May 21, 2014). Older records may be monthly rather than daily.
