Can I ask for diversion when dredging ditches that have been abandoned for decades?

It can be diverted, but it needs to be reported for approval. River diversion is not a trivial matter, involving major issues such as planning, safety and environmental protection. Strict feasibility study and scientific design must be carried out, planning and design should be carried out according to the international situation, and the river diversion scheme and construction scheme should be put forward in consultation with relevant departments such as planning, water conservancy, environmental protection and safety, and approved by government decision-making departments. Diversion can only be carried out after approval.
