Is Monroe Lake full?
Yes, and then some — 0.3 ft above full pool as of September 22, 2026
How full is Monroe 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.
Monroe Lake through the year
The band is the lake's own normal: where the level has run on each calendar day, 2002–2026. The summer drawdown — and how this year sits in it — shows up without reading a single number.
This year vs the years that matter
This year's trace against last year and the driest and wettest years on record — the drought-context question every lake regular asks.
- 2026 (this year)
- 2025 (last year)
- 2008 (wettest on record)
- 2012 (driest on record)
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 | 538.00 ft NGVD29 · per USACE Louisville District / Indiana DNR full-pool reference |
|---|---|
| Conservation capacity | 182,200 acre-feet · per USACE Louisville District / Indiana DNR capacity reference |
| Gauge | USACE lake gauge · U.S. Army Corps of Engineers Access to Water data — The Louisville District's own record of this pool runs back to September 2002; the USGS gauge near Harrodsburg only began publishing in 2023, so the history here is the Corps' series. |
| Datum | NGVD29 — Top of the normal summer pool is 538.0 ft. |

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.
