For the past three years, CS Environmental has been part of a project that identified more than 13 000 barriers to fish passage in South East Queensland, across 14 catchments. These movement barriers include weirs, culverts, bridge crossings, walkways, roads and tidal bunds.
Barriers were prioritised in order to develop potential remediation options that would allow fish to complete their migratory life-cycles, often between estuarine and freshwater environments. A number of sites were then selected for remediation to have fish ladders or ‘fishways’ designed and constructed as part of the project to demonstrate the effectiveness of these types of structures. This video highlights the fishways and the monitoring that occurred following remediation works with outstanding results in fish passage rehabilitation.
This project was co-funded by local councils and Reef Catchments NRM through the Australian Government’s National Landcare Program. Fishway design and construction was delivered by CS Environmental. This video was produced by Kim Kleidon, edited by Jac Kotze.
