Murray-Darling Basin
The Murray-Darling Basin is the catchment for the Murray and Darling Rivers and all their tributaries, covering most of inland NSW and extending from Queensland to South Australia. It is the twentieth largest river catchment in the world, covering more than a million square kilometres, and contains 22 major catchments.
It is a significant area for food production and aquatic ecosystems. Appropriate water usage in the Basin is important, both nationally and for the more than two million people who live within the Basin. Historically, the Murray-Darling Basin was managed by the States. However, in an effort to improve the environmental outcomes of the Basin as a whole, the first Murray-Darling Agreement was reached in 1987.
