Yanga National Park is in the southern Murray-Darling Basin. It is an important site for plants and animals to live and breed, but after years of having low water flow and little rain, the rivers, wetlands and floodplains became unhealthy.
Two sites in the park, Mercedes Swamp and the Two Bridges Wetland complex received environmental water in late 2009 to provide drought refuges, sustain waterbird breeding, support the great egret rookery and flood river red gum forests.
The Australian Government and the New South Wales Government sent enough water to fill over 4000 swimming pools to help make the sites healthy again.
By January, some four hundred waterbirds were breeding, including great egrets, cormorants, spoonbills, ibis and herons. Tadpoles of the nationally threatened southern bell frogs were also seen.
Healthy rivers are vital to the health and survival of many plant and animal species as well as to farming communities, towns and major cities. Environmental watering helps maintain the health of our rivers and wetlands.
