1162.35 ft project datum
level 0.3 ft above full pool — this gauge's public record is too short for seasonal comparisons
Reading comes straight from U.S. Army Corps of Engineers Access to Water data (USACE lake gauge) and updates live when you load this page.
Is Curwensville Lake full?
Yes, and then some — 0.3 ft above full pool as of October 1, 2026
How full is Curwensville 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.
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 | 1162.00 ft project datum · per USACE Baltimore District full-pool reference |
|---|---|
| Conservation capacity | 7,483 acre-feet · per USACE Baltimore District capacity reference |
| Gauge | USACE lake gauge · 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.
