Cooloolabin
About Cooloolabin
Cooloolabin Dam is located approximately five kilometres from Yandina, across Rocky Creek and provides drinking water as part of the SEQ Water Grid.
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.

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 Cooloolabin Dam, this is Sunshine Coast Regional Council.
