Lakes (WRRL) Lower Saxony

The smallest demarcated hydrological level of the EC Water Framework Directive (WFD) is the water body (WK). Lakes with a water area greater than 50 ha are considered separate marine water bodies for the WFD.The water body characterisation and evaluation is integrated as an attribute with results of the assessment of the ecological state/potential and the overall chemical state for the creation of theme maps.欧洲委员会水框架指令（Water Framework Directive, WFD）中划定的最小水文等级单元为水体（WK）。水域面积大于50公顷的湖泊，将被视为该指令框架下的独立海洋水体。水体特征描述与评估将整合为一项属性，关联生态状态/潜力及整体化学状态的评估结果，用于专题地图的制作。
