Barrages en Pays de la LoireDams in Pays de la Loire
This API provides a dataset of dams overseen by the Hydraulic Structures Safety Control Service (Service de Contrôle de la Sécurité des Ouvrages Hydrauliques) of DREAL Pays de la Loire, the regional environment authority in western France. Dams are classified into four categories (A to D) based on their height above natural ground level and the volume of water they impound, following French regulatory thresholds. The data covers the Pays de la Loire region and is useful for assessing hydraulic infrastructure, safety monitoring, and regional risk management related to water retention structures.Barrages contrôlés par le Service de Contrôle de la Sécurité des Ouvrages Hydrauliques de la DREAL Pays de la Loire. On distingue 4 classes de barrages : classe A : hauteur de l’ouvrage supérieure à 20 m par rapport au terrain naturel classe B : non A et h 10 m et 200 (V volume de la retenue) cla...
