The Government’s instruction of 3 June 2015 asked the State services to carry out a mapping of the rivers in each department in order to implement the law on water and defining what a watercourse is. In order to characterise watercourses, the State services, in collaboration with local actors, refer to the criteria set out in Article L. 215-7-1 of the Environmental Code: — the presence of a bed, originally natural; — power from a source; — a sufficient flow rate for most of the year. In order to determine a watercourse, all three criteria must be met in the affirmative.
