The Lachlan river is in the area where the aboriginal people called the Wiradjuri lived. The Wiradjuri land has been called "the land of the three rivers, the Wambool (Macquarie), the Kalare (Lachlan) and the Murrumbidjeri (Murrumbidgee) . The Murray River was the south side of Wiradjuri land. The change from forest to open grassland was the east side."
