Lachlan River, Major river system in New South Wales, Australia
The Lachlan River is a major river system extending over 1,440 kilometers (900 miles) across New South Wales. It originates in the Great Dividing Range and flows through central and western regions before joining the Murrumbidgee River.
George William Evans discovered the river in 1815 and named it after Governor Lachlan Macquarie. Aboriginal peoples had occupied and traveled along these waterways for thousands of years before European arrival.
The Wiradjuri people have inhabited these lands for thousands of years, calling the waterway Kalari or Galiyarr in their language. Water from this river shaped how communities lived, moved, and gathered food across the region for countless generations.
The river supports extensive farming and agricultural activities, providing irrigation water to farms across the central and western regions. Many communities depend on this water source for livestock operations and crop production throughout the year.
Nine wetland areas of national importance exist along the river's course, including Lake Cowal-Wilbertroy, Lake Cargelligo, and Lake Brewster. These shallow lakes support diverse bird species and provide critical habitat for plants and animals found nowhere else in the region.
