Maroon Dam is situated on Burnett Creek and supplies water for irrigation as part of the Logan River supply scheme.
Completed in 1974, Maroon Dam allows irrigation along Burnett Creek and the Logan River for about 130 kilometres downstream.
Maroon Dam is an un-gated dam that operates differently from the other un-gated dams. Instead of flowing over the spillway and safely out of the dam when the dam reaches 100 per cent capacity, we release water from Maroon Dam through cone valves.
To better reflect the way we operate Maroon Dam, we have changed the content of our Maroon Dam notifications as part of our Dam Release Notification Service. If you would like to be notified when Maroon Dam outflows have increased from the cone valves, sign up to our free dam release notification service or download our public safety mobile app. For more information about Maroon Dam notifications, click here.

The primary purpose of Maroon Dam is to supply water for irrigation under the Logan River water supply scheme.
Maroon Dam is situated south of Boonah and has a catchment area of 106 km2. The dam holds 44,319 million litres of water at full supply.

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 Maroon Dam, this is Scenic Rim Regional Council.
