What are fishways?
Fishways are artificial structures (also called fish ladders) that allow fish to pass over or through locks, dams and other waterway structures. Fishways at the barrages enable fish to move freely between the Coorong and Lower Lakes as part of their breeding and feeding cycle.
What has happened to date?
A small fishway at the Pelican Point end of the Tauwitchere Barrage was installed in 2009 as part of The Living Murray program; another was installed at the mouth of Hunters Creek on Hindmarsh Island in 2008. Other existing fishways include structures at Goolwa and Tauwitchere barrages.
What is happening next?
Up to six new fishways will be built at the Murray Mouth barrages to provide for a broader range of fish types and swimming behaviours and to allow the passage more fish during peak migration times. The South Australian Research and Development Institute (SARDI) will monitor the new fishways for effectiveness and to find ways to improve them.
Who is carrying out this work?
The new barrage fishways are being installed by the Coorong Lower Lakes and Murray Mouth Recovery Program, funded by the Australian Government and the Government of South Australia.
