Darling River facts
The Darling River is the lifeblood of Outback NSW. Only 15 per cent of the Darling's water comes from within the Western Catchment. It belongs to a complex system with highly variable flows which are affected by actions upstream.
Fish can climb ladders
Fishways (or fish-ladders) provide passage for fish normally stranded at the base of a weir. Fishways allow them to move along rivers to deed and breed, resulting in increased native fish numbers. The Western Catchment Management Authority (CMA) is supporting the installation of fishways at the Brewarrina and Bourke weirs.
Charles Sturt originally named the Darling 'Salt River'
Salinity is not a new phenomenon. Natural underground flows of salty water enter the Darling at several points including he one Where Sturt attempted to water his horses in 1829. Salinity is being managed by protecting and rehabilitation waterways, and native vegetation, changes in land and water management and engineering works.
Tilpa means 'floodwater' in the local Aboriginal Baarindji language
Floodplains operate in large flood events where the river breaks out of its banks. Due to the flat nature of the Western Catchment, floodwaters can slowly spread for tens of kilometres across the landscape, rejuvenating the plant and animal life if the area and enabling fish breeding to occur.
80% of Murray Cod are found within 1 metre of a snag
Snags are the inland equivalent of marine reefs. Trees and branches that have fallen into the river provide habitat, feeding and spawning sites and shaded resting areas. The Western CMA has re-introduced stages to encourage native fish numbers, replacing the snags removed during the days of the paddle-steamers.
The Western Catchment supports 471 animal species and 1,351 plant species
One species ins the iconic Red-tailed Black Cockatoo (Calptorhynchus bankii) along the Darling. The Western CMA assists in protecting and re-establishing riverbank vegetation, some of which will become homes for future generations of these magnificent birds.
