Full pool, datum, and the gauge
"Full pool" here means the conservation pool — the level the lake is designed to hold for water supply and recreation, not the flood-control space above it. The full explainer covers flood pool and dead pool too.

| Datum | NAVD88 — USACE runs the Menasha and Neenah dams to a seasonal strategy rather than one full pool, so no fixed full-pool elevation is published for Winnebago. |

LakeDates reports lake level, not ramp status. Whether a given ramp or marina is usable at this level varies ramp by ramp — call the marina before you tow.
