What this level means

The level comes from gauge 08092500, Whitney Lk nr Whitney, TX, and carries the time it was taken. That put the reservoir at 93% of its conservation capacity. Over the record shown on the level page the gauge has moved between 531.31 ft and 534.43 ft (low on 2025-11-19, high on 2026-06-09). The top of the dam sits at 580.0 ft. The Corps of Engineers puts the top of the flood pool at 571.0 ft. The last value stored here, 531.33 ft, is from 2026-09-09. Conservation capacity is 564,808 acre-feet. The conservation pool tops out at 533.0 ft. A falling pool widens the beaches and shortens the ramps, so it is worth checking before you drive out.

Over the last 400 days the gauge has ranged from 531.31 ft (2025-11-19) to 534.43 ft (2026-06-09). These are the limits of that window, not all-time records.

How this reading is taken

USGS gauge 08092500 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 Whitney is 533.0 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.

Water level questions

What is the current water level at Lake Whitney?

The latest reading is 531.33 ft, 1.7 ft below the 533.0 ft full pool, from USGS gauge 08092500.

How full is Lake Whitney?

It was last reported at 93% of conservation capacity, holding 527,312 of 564,808 acre-feet.

What is full pool at Lake Whitney?

Full pool is 533.0 ft. Water above that level is flood storage and is released as conditions allow.
