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 | 1572.00 ft project datum · per USACE Baltimore District full-pool reference |

| Gauge | USACE series Stillwater.Elev.Inst.1Hour.0.Best-NAB-Smoothed · U.S. Army Corps of Engineers Access to Water data |
| Datum | project datum — The district publishes the gauge and the top of conservation pool figure in the project's own datum, so the two compare like for like. |

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.
