What this level means
The level comes from gauge 02393500, ALLATOONA LAKE NEAR CARTERSVILLE, GA, and carries the time it was taken. The Corps of Engineers puts the top of the flood pool at 860.0 ft. The top of the dam sits at 870.0 ft. The last value stored here, 838.22 ft, is from 2026-09-09. Over the record shown on the level page the gauge has moved between 824.44 ft and 841.59 ft (low on 2026-01-01, high on 2026-07-27). When the pool drops, shoreline beaches grow and shallow ramps can run out of concrete.
How this reading is taken
USGS gauge 02393500 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 Lake Allatoona 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.
