Fresh water body by its centroid — Tarn

Water bodies refer to a surface, open, natural or anthropogenic surface freshwater area of varying depths. The term “water body” covers a number of situations commonly referred to as lake, containment, pond, gravel, quarry or marsh. By convention, water bodies corresponding to gravel or quarries during the period in which they fall under the mining code are not included in this layer. Water bodies are described by their use(s) according to a predefined usage typology. By convention, for the sake of consistency with Cascade, the typology ‘pisciculture’ shall apply, irrespective of the species produced, to a use of the water body covered by: either the rules on ICPEs (heading 2130 of Decree 206-942 of 27 July 2006) when regular feeding and production exceeding 20T/year; Article L431-6 of the Code de l’environnement et de la police de l’eau (section 3.2.7.0 of Decree 206-881 of 17 July 2006) if there is no regular feeding or production less than 20T/year. Water bodies of more than 1 000 m² and some exceptions corresponding to water bodies covered by a water law file are listed. A similar layer N_PLAN_EAU_S (#48) describes the right-of-way of water bodies.
