What this level means
Canyon Lake has no public water level gauge that we can read, so there is no level chart here. An invented number would be worse than none. Where an agency publishes a figure, we show it with the time it was taken; here there is none.
How this reading is taken
USGS gauge 08167700 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 Canyon Lake is 909.0 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 full pool at Canyon Lake?
Full pool is 909.0 ft. Water above that level is flood storage and is released as conditions allow.
