What this level means
The level comes from gauge 04084255, LAKE WINNEBAGO NEAR STOCKBRIDGE, WI, and carries the time it was taken. The last value stored here, 747.22 ft, is from 2026-09-09. When the pool drops, shoreline beaches grow and shallow ramps can run out of concrete.
How this reading is taken
USGS gauge 04084255 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 Winnebago 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.
