The dam is a few kilometres upstream of Yandina, on the South Maroochy River.

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 Wappa Dam begins to spill, please sign up to our free dam release notification service.


Barbecue and picnic facilities are available for public use, and there is also a small playground.

No water-based recreational activities (including fishing from the shoreline) are permitted.

Download the Wappa Dam Recreation Guide for detailed information about activities, as well as maps and important safety information.
