Lachlan River

The Lachlan River is an intermittent river that is part of the Murrumbidgee catchment within the Murray–Darling basin, located in the Southern Tablelands, Central West, and Riverina regions of New South Wales, Australia.The Lachlan River is connected to the Murray Darling basin only when both the Lachlan and Murrumbidgee Rivers are in flood. It is the only river in New South Wales with significant wetlands along its length, rather than just towards its end, including Lake Cowal-Wilbertroy, Lake Cargelligo and Lake Brewster, and nine wetlands of national significance.CourseThe river rises on the western slopes of the Great Dividing Range in the Southern Tablelands district of New South Wales, formed by the confluence of Hannans Creek and Mutmutbilly Creek, east of Gunning. The river flows generally north-west, north, west and south-west, joined by thirty-seven tributaries including the Crookwell, Abercrombie, Boorowa, and Belubula rivers before terminating near Oxley in the 500km2 Great Cumbung swamp that joins the Murrumbidgee River to the south and becomes part of the Lowbidgee Floodplain. The river descends over its 1440km course.
