Lake Tyler storage in context

Lake Tyler water level, past 12 months

89.4% full at the latest reading - across the past 12 months it ranged from 89.4% (September 8, 2026) to 99.0% (July 17, 2026). Percent full is storage against the 72,073-acre-foot capacity basis, not a share of the elevation plotted above.

Lake Tyler elevation, full record

89.4% full at the latest reading - across the storage record since October 2, 1985 it ranged from 54.1% (December 10, 2006) to 101.6% (June 28, 1986). Percent full is storage against the 72,073-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.
