Pomona Lake through the year
The band is the lake's own normal: where the level has run on each calendar day, 1990–2026. 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)
- 2019 (wettest on record)
- 1994 (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 | 974.00 ft project datum · per USACE Kansas City District full-pool reference |
|---|---|
| Conservation capacity | 55,514 acre-feet · per USACE Kansas City District capacity reference |
| Gauge | USACE series POMA.Elev.Inst.1Hour.0.Best-NWK · 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.
