Lake Sonoma through the year
The band is the lake's own normal: where the level has run on each calendar day, 1988–2026. 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 (wettest on record)
- 2022 (driest on record)
- 2025 (last year)
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 |
|---|---|
| Conservation capacity | 381,000 acre-feet · per US Army Corps of Engineers (Sonoma Water) capacity reference |
| Gauge | CDEC station WRS · California DWR — California Data Exchange Center |
| Datum | US Army Corps of Engineers — Full pool null: top of water supply pool ~451 ft is commonly cited but no agency page verified; flood pool extends far above. Current 450.5 is effectively a full supply pool |
| Last verified | August 15, 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.
