The definition of 'waterway' under the Fisheries Act is broad and a Queensland-wide spatial data layer has been developed to better delineate this. Waterway barrier works are regulated under the Fisheries Act 1994 and the Sustainable Planning Act 2009 when barriers to fish movement, including partial barriers, are installed across waterways.
The data layer assists in the determination of whether the site of proposed waterway barrier works requires assessment and approval under the Fisheries Act 1994. In addition, waterways have been colour-coded along their length to show the risk of adverse impact from in-stream barriers on fish movement and whether a waterway barrier works can potentially proceed under the relevant Fisheries Queensland self-assessable code or whether the works will require a development approval.
Barrier works include construction, raising, replacement and some maintenance works on structures such as culvert crossings, bed level and low level crossings, weirs and dams, both permanent and temporary.
