Lake Alan Henry water level

What this level means

Station 08079700, Lk Alan Henry Res nr Justiceburg, TX, publishes the water surface elevation used here. The last value stored here, 2,208.97 ft, is from 2026-09-09. Conservation capacity is 96,207 acre-feet. The agency sets full pool at 2,220.0 ft. That put the reservoir at 72% of its conservation capacity. Over the record shown on the level page the gauge has moved between 2,209.01 ft and 2,218.37 ft (low on 2026-09-08, high on 2025-08-05). When the pool drops, shoreline beaches grow and shallow ramps can run out of concrete.

How this reading is taken

USGS gauge 08079700 measures the water surface and publishes the value continuously. This page stores the latest reading at build time and refreshes the record daily, so the figure above is a real measurement rather than a model or an estimate.

Full pool for Lake Alan Henry is 2,220.0 ft, so the gap between the reading and that number is what the reservoir is missing.

Elevations are given in feet above the gauge datum used by the operating agency. Two lakes are only comparable with each other through how full they are, not through their raw elevation, because each dam sits at a different height.
