What this level means
The level comes from gauge 08206900, Choke Canyon Res nr Three Rivers, TX, and carries the time it was taken. The agency sets full pool at 220.5 ft. The last value stored here, 191.66 ft, is from 2026-09-09. That put the reservoir at 23% of its conservation capacity. Over the record shown on the level page the gauge has moved between 178.24 ft and 192.90 ft (low on 2026-05-18, high on 2026-08-01). Conservation capacity is 662,820 acre-feet. Beach width and ramp access both move with the pool, so the number above is worth a look first.
How this reading is taken
USGS gauge 08206900 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 Choke Canyon Reservoir is 220.5 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.
