Bromfield weir removal success

Warrnambool’s Bromfield Street weir, a longstanding barrier to fish migration in the Merri River, has been successfully removed.

The removal of the weir, which was a collaborative effort between local authorities, environmental organisations, and community stakeholders was funded by Victorian Government’s $248 million investment over four years (2020-2024) to improve catchment and waterway health across regional Victoria.

The Bromfield Street weir was constructed in 1907 as part of the Merri scheme to supply town water to Warrnambool, and despite this scheme being decommissioned in 1939, the weir remained in the waterway.

The aging structure of the weir, which has become unsafe over time, has been identified as key a barrier to the natural flow of the Merri River and an impediment to fish passage in the waterway. 

The removal process was carried out with careful consideration for environmental impact and community engagemen with environmental experts and engineering teams from Glenelg Hopkins CMA and Murrihy’s demolition employed best practices to dismantle the weir while minimising disturbance to the surrounding ecosystem.

Additionally, community input and support were integral in ensuring the success of the removal project. 

The removal of the Bromfield Street Weir is expected to have far-reaching benefits for the Merri River ecosystem and the wider Warrnambool community who enjoy recreational activities on waterway.

Improved fish migration will enhance genetic exchange among populations, increase biodiversity, and contribute to the overall ecological balance of the river system.

Additionally, the waterway is now much more accessible for people to enjoy the recreational benefits of the river like kayaking and fishing … removing the weir means access to the upper reaches of the river without needing to pull a kayak or canoe around the weir.

Rehabilitation works will continue in upcoming weeks following the removal of the structure including revegetating bank areas.
