French River Level and Flow Observations, Near Real Time (Hub'Eau)

hubeau/river-levels-realtime

A page of near-real-time observations from the French national hydrometric network (more than 6000 stations): water level (grandeur_hydro H) or flow (Q) with the station and site code, observation time in UTC, value, measurement method, qualification, status and station coordinates. You choose how many records to return; the tool takes no station filter, so it returns whichever records the service lists first. Recent observations are often raw ('Brute') and not yet qualified. Data from Hub'Eau, producers OFB / BRGM / SCHAPI-Vigicrues, Licence Ouverte Etalab; served by Eden Engine; not an official Hub'Eau product.
