What this level means
The level comes from gauge 03374498, PATOKA LAKE NEAR CUZCO, IN, and carries the time it was taken. The top of the dam sits at 564.0 ft. The last value stored here, 540.13 ft, is from 2026-09-09. The Corps of Engineers puts the top of the flood pool at 548.0 ft. A falling pool widens the beaches and shortens the ramps, so it is worth checking before you drive out.
How this reading is taken
USGS gauge 03374498 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.
No operating agency publishes a full pool elevation for Patoka Lake that we can cite, so this page shows the reading and its trend without a percentage.
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.
