Mining and petroleum activities: Interfering with a waterway

The Water Act 1992 applies to mining and petroleum activities.

Mining and petroleum activities that interfere with a waterway need to comply with the Water Act 1992.

A transition period is in place to enable existing authorised mining and petroleum activities to comply with the Water Act 1992 within a reasonable timeframe.

For the transition period to apply, the mine or environment management plan must have been:

  • approved before 1 July 2019 or
  • submitted for approval before 1 July 2019 and then approved with no change.

The transition period does not apply to hydraulic fracturing activities.

Section 4 of the Water Act 1992 defines a waterway and includes:

  • a river, creek, stream or watercourse
  • a perennial or ephemeral natural channel
  • a perennial or ephemeral artificial channel that was constructed by altering or relocating a river, creek, watercourse or natural channel
  • a lake, lagoon, swamp or marsh in which water collects and that is connected to a river, creek, stream or watercourse
  • a floodplain.

A waterway does not include any artificial channel or diversion works constructed on a floodplain.

Interference with a waterway includes any activity that causes:

  • a material change to the shape of a waterway
  • a material change to the volume, speed or direction of the flow of a waterway
  • an alteration to the stability of the bed or banks of a waterway, including vegetation removal.

Examples of works that may constitute interference with a waterway include:

  • construction or alteration of a dam
  • diversion or realignment of a waterway
  • flood mitigation works such as a levee
  • extraction or deposition of material
  • waterway crossing
  • outlet structures
  • erosion and control works.

Contact the Water Resources Division for advice if you think your activity may interfere with a waterway.

Retrospective applications to obtain a permit to interfere with a waterway may not be accepted.
