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.

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

Please note the flying fox at Jack Harrison Park is temporarily closed (as of Tuesday 8 April 2014). Seqwater is assessing what is required to rectify the issues, and will carry out those works as soon as possible.

The remaining playground equipment in the park is available for use, and we trust that people will still enjoy their visits to Jack Harrison Park.

Note: Recreation at, and access to, our sites may have changed since the recreation guides were published in 2014. We are in the process of updating these guides to simple one-page recreation maps. Until then, please refer to for the most recent updates about recreation activities and site access.
