Dams in Queensland

Queensland's water dams fulfil many purposes and roles including:

  • water for towns and communities
  • water for industry and agriculture
  • water for hydropower
  • water storages to provide a degree of flood mitigation to downstream communities
  • water storages for recreational facilities.

Dam ownership and operation

The Department of Natural Resources, Mines and Energy's role in managing the safety of dams includes:

Seqwater and SunWater own and operate almost half of Queensland's referable dams: Seqwater has 26 large dams and SunWater has 23 large dams.

Dam owners are responsible for the safety of their dams.

Referable dam owners are required to have approved emergency action plans in place for their dams.

Other dams

Hazardous waste dams or other dams that are regulated under the Environmental Protection Act 1994 are managed by the Department of Environment and Science.


In an emergency, phone 000.
