What this level means
The level comes from gauge 08046500, Benbrook Lk nr Benbrook, TX, and carries the time it was taken. The Corps of Engineers puts the top of the flood pool at 724.0 ft. That put the reservoir at 77% of its conservation capacity. Conservation capacity is 85,648 acre-feet. The top of the dam sits at 747.0 ft. The last value stored here, 688.02 ft, is from 2026-09-09. Full pool is 694.0 ft. A low pool exposes stumps and mud in the shallow arms of the lake.
How this reading is taken
USGS gauge 08046500 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 Benbrook Lake is 694.0 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.
