About Sideling Creek Dam

Also known as Lake Kurwongbah, Sideling Creek Dam is located in the Moreton Bay Regional Council area.

The dam is built on a tributary of the Pine River. It was commissioned in 1957 and upgraded in 1969.

It is an un-gated dam, meaning that when it reaches 100 per cent capacity, water flows over the spillway and safely out of the dam.

If you would like to be notified when Sideling Creek Dam begins to spill, sign up to our free dam release notification service or download our public safety mobile app.

The surrounding environment and recreation facilities available make Lake Kurwongbah are popular for a variety of activities.

    Sideling Creek Dam is a drought response dam and can be used as a drinking water storage, as part of the SEQ Water Grid, when it's needed. With a catchment area of 53km2, Sideling Creek Dam can hold up to 14,192 million litres of water at full supply.

  • Flood mitigation

    All dams help mitigate flooding to some extent. The peak outflow from a gated or un-gated dam during a flood event is less than the peak outflow that would have occurred had the dam not been built, because some water is held in the dam while it is spilling. This means that water flow slows down as floods pass through the dam.

    It’s important neighbours and people downstream of dams know what to do in the unlikely event of an emergency. Each of our dams have an emergency action plan (EAP) in place to enable us to respond quickly to potential incidents in partnership with the Bureau of Meteorology, relevant emergency services and local councils. For Sideling Creek Dam, this is Moreton Bay Regional Council.
