French River and Lake Water Quality Monitoring Stations (Hub'Eau, Naiades)
hubeau/river-water-quality-stations
Lists the French river and lake stations (overseas territories included) where physico-chemical water quality samples are taken, from the Naiades bank: station code and name, commune, department, region, coordinates, river and water body where known, and creation and update dates. Choose how many stations to return (1 to 50) and optionally filter by commune INSEE code. This lists the stations only, not the analysis results. The upstream service is slow, often around 20 seconds. Data from Hub'Eau, producers OFB / BRGM / SCHAPI-Vigicrues, Licence Ouverte Etalab; served by Eden Engine; not an official Hub'Eau product.
