What this level means
The level comes from gauge 03326950, MISSISSINEWA LAKE AT PEORIA, IN, and carries the time it was taken. The Corps of Engineers puts the top of the flood pool at 779.0 ft. The top of the dam sits at 797.0 ft. The last value stored here, 739.12 ft, is from 2026-09-09. The agency sets full pool at 737.0 ft. Water level decides what is usable on the shoreline, from beach width to ramp access.
How this reading is taken
USGS gauge 03326950 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 Mississinewa Lake is 737.0 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.
