Lake Nacogdoches storage in context

Lake Nacogdoches water level, past 12 months

88.0% full at the latest reading - across the past 12 months it ranged from 87.8% (September 1, 2026) to 98.2% (March 16, 2026). Percent full is storage against the 39,522-acre-foot capacity basis, not a share of the elevation plotted above.

Lake Nacogdoches elevation, full record

88.0% full at the latest reading - across the storage record since March 2, 1977 it ranged from 37.6% (March 2, 1977) to 107.1% (July 3, 1993). Percent full is storage against the 39,522-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.
