About this gauge
Merville is a gauge on the Lys in Nord, France.
It lies at 50.6392° N, 2.6411° E.
Its readings come from France's national network of river gauges (Vigicrues and its partners), through Hub'Eau.
The gauge reads the height of the water above a fixed zero, not the depth of the river. Its zero lies at 13.27 m above NGF-IGN69 (the French sea-level datum).
Hub'Eau's daily highs for this gauge go back to 18 December 1999.
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.
