Works completed at Holdfast Crossing
The department’s Water Group has recently completed works to remove a concrete structure blocking fish migration known as Holdfast Crossing. The crossing is located approximately 14km North of Yetman in the Inverell Shire.
The removal reinstated more than 64km of fish passage.
About the project
The Fish Passage: Reconnecting the Northern Basin project seeks to reinstate waterways that allow native fish to flourish, while at the same time balancing the needs of local water users.
The project involves:
- construction of fishways at priority weir sites at Banarway, Calmundi and Louth
- the removal of an unlicensed structure on the Darling-Baaka River.
Native fish need to migrate to complete key life stages and to avoid drying habitats during drought. The distance migrated ranges from a few kilometres to entire river systems in the case of species like Golden Perch.
The department’s Water Group recognises the importance of balancing the needs of water users and the environment carefully. The project aims to address barries to fish passage, including the construction of fishways on infrastructure within our river systems.
The project aims to reinstate more than 370km of fish passage along the Barwon-Darling River system and more than 80km of fish passage along Macintyre River.
The Water Group continues the detailed design process for the fishways, including an investigation of design options balancing the needs of the environment and local water users.
This process can take time, so we will be in contact with residents, local councils and key stakeholders as soon as we have an update on these options.
We continue to progress supporting activities for the fishways including the review of environmental factors, procurement strategies and licensing and agreements.
The construction of the fishways is due for completion by December 2026.
An assessment of reinstated fish passage at Toomelah Weir has been completed. Works to remove the existing causeway at Holdfast Crossing was completed in September 2024. Works to remove an unlicensed structure on the Darling-Baaka is expected to begin in early 2025.
The project will generate significant benefits, including:
- increased movement of native fish species across the northern NSW Murray Darling Basin
- increased abundance of native fish species in the system
- enhanced cultural values for First Nations communities (native fish are an important part of First Nations cultures in the region)
- support for regional economies and the creation of local job opportunities during construction
- increased regional tourism opportunities as native fish populations increase.

Project funding
The project is funded by the Australian Government and is being delivered to support the Murray–Darling Basin Plan by the department’s Water Group in partnership with the Department of Primary Industries – Fisheries.
The Australian Government has allocated up to $56.8 million to fund the project.
About fishways
Fishways are structures placed on or around constructed barriers, such as dams or weirs, to provide a passageway to help fish migrate safely upstream and downstream.

Stakeholder engagement
We will continue to provide opportunities for local communities and stakeholders to have their say on the project throughout its stages of development and delivery, and this feedback will be used as a key input into project decision-making.

Upcoming engagement opportunities will also be listed on this webpage and on our stakeholder engagement page.
Engagement with First Nations people
We recognise and acknowledge the unique relationship and deep Connection-to-Country that First Nations people have as the Traditional Owners and First Peoples of Australia.
The wisdom and experience of First Nations communities will play a role in informing our approach. We have a dedicated engagement team who will guide our engagement with these communities, and we look forward to working with them to deliver real and tangible outcomes.
