Australian native fish have evolved to utilise a variety of habitat types to complete their life cycle, thus requiring unimpeded ‘migratory’ access along water at different times to survive and reproduce (e.g. by accessing food and shelter, avoiding predators, reducing localised competition, and finding mates). However, in Australia riverine connectivity has been severely disrupted by…

In the Lachlan Catchment there are also nine regionally significant wetlands, four in the mid-Lachlan between Forbes and Lake Cargelligo (including Lake Cargelligo itself) and five below Lake Cargelligo. Regionally significant wetlands are recognised in part on the basis of their meeting one of the five criteria below, which was developed for identifying a key…
The Lachlan Catchment contains eight nationally significant wetlands, five associated with the swamps and effluent creeks in the lower catchment (Great Cumbung Swamp, Booligal Wetlands, Cuba Dam, Lake Merrimajeel—Murrumbidgil Swamp and Merrowie Creek–Cuba Dam to Chillichil Swamp) and three in the middle catchment (Lake Cowal–Wilbertroy Wetlands, Lake Brewster and Lachlan Swamp; (NOW, 2010c)). The eight…
The installation and operation of in-stream structures and other processes that alter natural flow regimes is a listed Key Threatening Process under the Fisheries Management Act 1994 and the Threatened Species Conservation Act 1995 (DPI, 2006). Recommendations put forward by the acts specifically note the impact of in-stream structures on the life histories of threatened…
Background There are nine native fish species that call the Lachlan River home. Many of these fish species migrate short and long distances to spawn, feed and seek shelter. Structures such as dams, weirs, regulators and poorly designed road crossings can create physical barriers that prevent fish movement up and down the river, and stop…
