Is Lake Red Rock full?
Yes, and then some — 4.0 ft above full pool as of September 24, 2026
How full is Lake Red Rock? 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.
Lake Red Rock through the year
The band is the lake's own normal: where the level has run on each calendar day, 2011–2026. 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 | 742.00 ft NGVD29 · per USACE Rock Island District full-pool reference |
|---|---|
| Conservation capacity | 189,020 acre-feet · per USACE Rock Island District capacity reference |
| Gauge | USACE lake gauge · U.S. Army Corps of Engineers Access to Water data |
| Datum | NGVD29 — The pool gauge and the 742.0 ft top of the conservation pool are both NGVD29, so feet below full pool compare like for like. |
