What this level means
Readings come from station 08088500 (Possum Kingdom Lk nr Graford, TX). The last value stored here, 994.99 ft, is from 2026-09-09. Over the record shown on the level page the gauge has moved between 995.03 ft and 998.91 ft (low on 2026-09-08, high on 2025-08-05). Full pool is 999.0 ft. That put the reservoir at 87% of its conservation capacity. Conservation capacity is 538,139 acre-feet. The top of the dam sits at 1,024.0 ft. Water level decides what is usable on the shoreline, from beach width to ramp access.
How this reading is taken
USGS gauge 08088500 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 Possum Kingdom Lake is 999.0 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.
