Lake Texana storage in context

Lake Texana water level, past 12 months

86.9% full at the latest reading - across the past 12 months it ranged from 49.6% (April 10, 2026) to 100.0% (July 23, 2026). Percent full is storage against the 158,975-acre-foot capacity basis, not a share of the elevation plotted above.

Lake Texana elevation, full record

86.9% full at the latest reading - across the storage record since June 18, 1999 it ranged from 36.1% (January 8, 2012) to 100.0% (July 23, 2026). Percent full is storage against the 158,975-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.
