How will the Stage 3 project help with flood mitigation?
The Stage 3 works on the spillway allows flood mitigation to occur by delaying the release of floodwater into the lower reaches of the floodplain by raising the dam wall and temporarily storing a greater volume of water. The new dam design will also incorporate a new spillway, designed to reduce the flow of water from the dam during large rainfall events. By reducing the rate floodwater is released from the dam, peak flood levels and damage in the lower catchment can be reduced.
