Is Conchas Lake full?
Not quite — 23.4 ft below full pool as of September 24, 2026
How full is Conchas Lake? 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.
Conchas 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.

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.

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.
