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.(Definition given by the Sander).By convention are not included in this layer water bodies corresponding to gravel or quarries during the period when they fall under the mining code.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” applies, irrespective of the species produced, to a use of the water body falling under either the regulations on ICPEs (heading 2130 of Decree 206-942 of 27 July 2006) when it regularly feeds and production exceeds 20T/year;- or 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 it there is no regular feeding or production less than 20T/year.A similar layer N_PLAN_EAU_P (#47) describes the centroids of water bodies.A layer N_AUTRE_PISCI_S describes off-water fish farms.水体指具有一定水深的露天、天然或人工地表淡水区域。“水体”一词涵盖了通常被称为湖泊、蓄水体、池塘、砾石采砂坑、采石场或沼泽的多种场景，该定义由Sander提出。按照惯例，处于矿业法规管控周期内的砾石采砂坑与采石场类水体，不纳入本图层的统计范围。水体依据预设的用途分类体系，按其实际使用用途进行描述。为与Cascade标准保持一致，本分类体系中“水产养殖”类型的适用规则如下：无论养殖物种为何，若水体采用常态化投喂模式且年产量超过20吨/年，则适用2006年7月27日第206-942号法令第2130条中有关ICPE（Installations Classées pour la Protection de l'Environnement，环境分类注册设施）的相关规定；若未采用常态化投喂模式或年产量低于20吨/年，则适用2006年7月17日第206-881号法令第3.2.7.0节所规定的《环境与水法典》第L431-6条条款。另有同名图层N_PLAN_EAU_P（编号#47）用于标注水体的质心位置；图层N_AUTRE_PISCI_S则用于描述陆上水产养殖场。
