Alamo Lake through the year
The band is the lake's own normal: where the level has run on each calendar day, 2004–2026. 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.

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 | 1160.40 ft NGVD29 · per USACE Los Angeles District (Alamo Dam) full-pool reference |
|---|---|
| Conservation capacity | 321,716 acre-feet · per USACE Los Angeles District (Alamo Dam) capacity reference |
| Gauge | USACE series Alamo.Elev.Inst.1Hour.0.GOES-rev · U.S. Army Corps of Engineers Access to Water data |
| Datum | NGVD29 — Two figures matter on this lake: 1,160.4 ft is the top of the conservation pool, where flood storage begins, and 1,070 ft is the top of the recreation pool the state park is built around — so Alamo reads a long way below full pool through most of a normal year. |
