Lake Tawakoni storage in context

Lake Tawakoni water level, past 12 months

89.6% full at the latest reading - across the past 12 months it ranged from 89.6% (October 23, 2026) to 100.0% (July 7, 2026). Percent full is storage against the 871,685-acre-foot capacity basis, not a share of the elevation plotted above.

Lake Tawakoni elevation, full record

89.6% full at the latest reading - across the storage record since October 2, 1960 it ranged from 0.0% (October 2, 1960) to 107.4% (July 13, 2000). Percent full is storage against the 871,685-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.
