Watercourse mapping — Haute-Loire

Mapping of Haute-Loire watercourses carried out in accordance with the Government’s instruction of 3 June 2015 on the mapping, identification and maintenance of rivers. Based on the definition of a watercourse (a stream is a stream flow in a natural bed originally fed by a source and having a sufficient flow of much of the year), it is proposed in the interactive map to visualise the hydrographic sections of the IGN TOPO BD in two categories: “Watercourses” and “No streams” (see attribute of the layer called “TYPE_ECOUL”).
