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.

Full pool 5432.00 ft USACE project datum · per USACE Omaha District full-pool reference
Gauge USACE lake gauge · U.S. Army Corps of Engineers Access to Water data
Datum USACE project datum — Top of the multipurpose pool is 5,432.0 ft — the bottom of the flood-control space — so a reading slightly above it after a storm is the lake doing its job.

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.
