Fresh water body right-of-way — 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_P (#47) describes the centroids of water bodies.

水体（water body）指具有一定水深的地表开放型自然或人工淡水区域。"水体"这一术语涵盖了通常被称为湖泊、蓄水池、池塘、砾石坑、采石场或沼泽的多种场景。
按照惯例，在受矿业法规管控期间的砾石坑或采石场对应的水体，不包含在本图层中。
水体依据预定义的使用分类体系来描述其用途。
为与Cascade保持一致，按惯例，"水产养殖（pisciculture）"这一分类适用于符合以下任一情形的水体使用，无论其养殖物种为何：
要么适用2006年7月27日第206-942号法令第2130条中关于ICPE的相关规定，此时需定期投喂且年产量超过20吨；
要么适用《环境与水法典》第L431-6条（对应2006年7月17日第206-881号法令第3.2.7.0节），此时无需定期投喂或年产量低于20吨。
面积超过1000平方米的水体，以及部分由水法文件覆盖的水体特例，均已纳入列表。
编号为#47的N_PLAN_EAU_P图层描述了水体的质心，与本图层类似。
水体使用类型命名规则（完成于2012年10月13日，对应SANDRE命名法421）：
A: 灌溉蓄水（SANDRE代码=3）
B: 供水（AEP）蓄水（SANDRE代码=1）
C: 能源生产蓄水（SANDRE代码=5）
D: 航运蓄水（SANDRE代码=8）
E: 洪水调蓄（SANDRE代码=10.1）
F: 捕捞支撑（渔业生产）（梭鲈（Pike perch）代码=10.2）
G: 造雪蓄水（Pikeer代码=4）
H: 需定期投喂且年产量超过20吨的水产养殖（梭鲈代码=6.1）
I: 无需定期投喂或年产量低于20吨的水产养殖（梭鲈代码=6.1）
J: 畜禽饮水用途（梭鲈代码=3）
K: 专业捕捞作业（Sandpike代码=6.2）
L: 休闲用途：包含景观/认证用途（SANDRE代码=4）
M: 游泳用途（Sandstone代码=4.1）
N: 消防蓄水/DFCI（Sandstone代码=10.3）
上述可用用途列表并非穷尽式列举。
