Not quite — 0.5 ft below full pool as of October 1, 2026

How full is Big Sandy Lake? 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.
