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 | 100.00 ft Duke plant datum (100 ft full pond) · per Duke Energy full-pool reference |
|---|---|
| Gauge | NOAA gauge JCSS1 · NOAA National Water Prediction Service |
| Datum | Duke plant datum (100 ft full pond) — 100 ft plant datum = 1,100 ft msl full pond (Duke page); pumped-storage upper reservoir with 30 ft licensed drawdown, so double-digit feet below full is normal. |

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.
