How this reading is taken
USGS gauge 08154900 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 Austin is 492.8 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.
