Following heavy and consistent rainfall, Hinze Dam has been 100 per cent full during January.
Overtopping the passive spillway is the only means for excess water to escape from the dam, as it does not have an operating means of lowering the water level.
The $396 million Stage 3 project, which will substantially raise the height of the dam, will incorporate a raised spillway and, while there currently exists no means to quickly release water below the spillway level, the Stage 3 dam will have a lower level water release gate.
When Stage 3 is completed in late 2010, it will provide greatly improved flood mitigation in the downstream Nerang River catchments, as well as an increased water supply
