This API provides data on monitoring stations used to assess the water quality of rivers within the departmental network of Loire-Atlantique, France. It is published and maintained by the Département de Loire-Atlantique. For each station, the dataset includes location details, the associated river (cours d'eau), and the corresponding water body (masse d'eau). It is related to a companion dataset on surface water quality monitoring in Loire-Atlantique, which covers the same network of stations. The data supports environmental monitoring and water management at the local level.Stations du suivi de la qualité des cours d'eau du réseau départemental : localisation, cours d'eau, masse d'eau, etc. Voir aussi : Suivi qualité des eaux superficielles en Loire-Atlantique – stations du réseau départemental
