97.25 ft Duke plant datum (100 ft full pond)
level 2.8 ft below full pool — this gauge's public record is too short for seasonal comparisons

Is Lake Keowee full?
Not quite — 2.8 ft below full pool as of September 24, 2026
How full is Lake Keowee? Not as a percentage: no storage figure comes through with this gauge reading, and a share of capacity worked out from the elevation alone would be a guess — how much water a reservoir holds at a given level is a curve only the operator's own capacity table knows. Feet from full pool is what the operator publishes, and it is the figure above.
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 | Duke plant datum (100 ft full pond) — NWPS gauge KEOS1 reads Duke plant datum; 100 ft = full pond = 800 ft msl (Duke Keowee-Toxaway project page). NWS action stage is 100. |
