About this gauge

Grand-Santi is a gauge on the Maroni in French Guiana, France.

It lies at 4.2715° N, 54.3816° 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 2 August 1953.

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.
