About this gauge

Trézilidé is a gauge on the Guillec in Finistère, France.

It lies at 48.6160° N, 4.0764° W.

Its readings come from France's national network of river gauges (Vigicrues and its partners), through Hub'Eau.

Hub'Eau's daily highs for this gauge go back to 8 June 1966.

Hub'Eau's newest readings are mostly raw data that the gauge's operator checks and validates later.

The newest reading is provisional: the source may still correct it.
