This API provides data on feeder ponds (étangs d'alimentation) that supply water to navigable waterways and canals owned by the Brittany regional authority. It identifies and locates these water reservoirs, which are used to maintain water levels in the region's canal network. The dataset is published as part of the Brittany region's open data initiative and offers free, unauthenticated access, making it useful for water management, waterway maintenance, and geographic analysis of the region's inland navigation infrastructure.Etangs d'alimentation des voies navigables appartenant à la région Bretagne
