Lake Abilene storage in context

Lake Abilene water level, past 12 months

9.3% full at the latest reading - across the past 12 months it ranged from 3.5% (April 24, 2026) to 14.1% (July 19, 2026). Percent full is storage against the 7,900-acre-foot capacity basis, not a share of the elevation plotted above.

Lake Abilene elevation, full record

9.3% full at the latest reading - across the storage record since March 5, 1999 it ranged from 0.2% (September 1, 2000) to 100.0% (July 16, 2021). Percent full is storage against the 7,900-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.

Update cadence

Daily

TWDB reports conservation storage against a conservation capacity that is restated as new volumetric surveys are completed, so a percent-full figure here can change without the water level changing. TWDB's methodology page is linked in the notes below.
