Maintenance works and operations on a watercourse have an impact on the surrounding nature and are regulated by regulations. In a watercourse, only work that meets the definition of regular maintenance can be carried out without a prior record. In-water works requiring greater intervention than regular maintenance must be submitted a prior declaration or authorisation file under the Water Act. Watercourse mapping in the Landes Department is published on the State Services website. It is an evolutionary tool updated annually, in April.河道运维作业会对周边自然环境造成影响，相关活动受法律法规监管。在河道范围内，仅符合常规运维定义的作业可无需事前备案即可实施。相较于常规运维、需要更大作业规模的涉水工程，需依据《水法》提交事前申报材料或授权文件。朗德省（Landes Department）的河道测绘图已在国家行政服务网站发布，该测绘图为动态更新工具，每年4月完成版本更新。
