South Dubbo Weir Rock Ramp and Fishway

Construction of the rock ramp and fishway at South Dubbo Weir on 05/07/2016

Construction is now complete at the South Dubbo Weir, one of Dubbo Regional Council’s most important capital projects. This includes a rock ramp and fishway to allow native fish to move upstream and downstream through the South Dubbo Weir, providing great benefits for native fish stocks between Dubbo and Burrendong Dam.

The project had been designed to not only improve public safety at the site, but to also ensure the City’s future water supply. 

More importantly, the rock ramp will address priority safety issues. At the foot of the original weir, the water was extremely turbulent and induced a strong undertow current. With the new rock ramp, the depth is now shallower, and we’ve been able reduce the turbulence and also the risk of drowning.

The project had seen a number of challenges since the beginning of construction in March 2016.

The project was affected by a number of High Water Flow Events from a combination of water releases from Burrendong Dam for flood mitigation and high rainfall periods that resulted in the City experiencing its 6th wettest year in 145 years of records.

Nine people have drowned at the South Dubbo Weir since its construction in 1942 and it’s critical for Council to do what it can for the Region to prevent any further incidents. 

Council thanks the team at David Payne Constructions for all their efforts along with NSW Public Works who were engaged by Council to oversee the project.
