Construction of dams

The construction, enlargement or modification of a dam may require a water affecting activity permit or development authorisation.

Dam construction, enlargement or modifications to a volume of 5 ML (5,000 kilolitres) or less, and/or with walls of 3 metres or less above the natural ground surface can only be undertaken with a water affecting activity permit. Apply through the South East Natural Resources Management Board.

Dam construction, enlargement or modifications of a volume greater than 5 ML (5,000 kilolitres), and/or with walls greater than 3 metres above the natural ground surface can only be undertaken with development approval. Apply through your Local Council.
