Both permanent and temporary works affecting a watercourse may require consent. Temporary works could be the damming of a watercourse to allow permanent work such as the installation of a bridge.
Only certain types of work require consent. When considering if your works require consent, check if they would affect the flow of the watercourse when it is full to the top of the bank. If the flow of the watercourse, when it is full to the top of the bank, will be affected the work will need consent.
