Lewy Lake through the year
The band is the lake's own normal: where the level has run on each calendar day, 2010–2026. 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, driest on record)
- 2013 (wettest 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 | not published by the operator |
|---|---|
| Gauge | USGS gauge 01019300 · U.S. Geological Survey National Water Information System |
| Datum | NAVD88 — A natural lake in the Grand Lake chain with no published full-pool figure, so the reading stands against the lake's own record. |
| Last verified | August 26, 2026 |
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.
