What this level means
The level comes from gauge 08061550, Lk Ray Hubbard nr Forney, TX, and carries the time it was taken. That put the reservoir at 87% of its conservation capacity. The conservation pool tops out at 435.5 ft. The last value stored here, 432.67 ft, is from 2026-09-09. Over the record shown on the level page the gauge has moved between 432.71 ft and 436.01 ft (low on 2026-09-08, high on 2026-05-27). Conservation capacity is 439,559 acre-feet. When the pool drops, shoreline beaches grow and shallow ramps can run out of concrete.
How this reading is taken
USGS gauge 08061550 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 Ray Hubbard is 435.5 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.
