Where permitted, all new farm dams require a Development Application (DA) , as does any alteration work (excluding the cleaning of silt).

The technical guidelines for the construction of farm dams can be located in the Development Control Plan . The purpose of these controls is to ensure:
At the completion of the construction of the dam it will be require that certification from a registered surveyor that the dam does not exceed the approved capacity. Certification from a Geotechnical Engineer may also be required as a condition of consent if the dam is location in an area of unstable land. This is to ensure that the dam construction has been carried out in accordance with the technical requirements and the conditions of approval.
Any works within 40 metres of a water body will require a DA. It is recommended you speak to the duty planner to confirm the proposed works require no approval.

No approval is required to fix a leak in a dam as long as the following items are complied with:
Note: Many dams have been constructed with the materials available on the site. As such these dams have existing material on the site that can be used to fix a leak, broken wall, etc. It is recommended you speak to the duty planner to confirm the proposed works require no approval.
Any works that result in the increase of a Dam capacity will require a DA.
If material is not able to be harvested from the site to fix a dam up to 100 cubic metres of clean and certified material is permitted to be brought to the site without approval. Any works that require more material will require development consent.
It is recommended you speak to the duty planner to confirm the proposed works require no approval.
