The Macintyre River, a perennial river that forms part of the Border Rivers group, is part of the Barwon catchment of the Murray-Darling basin, located in the Northern Tablelands and North West Slopes regions of New South Wales, and the Southern Downs region of Queensland, Australia.[2]
Part of the course of the river marks the border between Queensland and New South Wales.
The Macintyre River rises on the western slopes of the Great Dividing Range, west of Guyra and south of Glen Innes, and flows generally northwest and west, joined by twenty-two tributaries, including the Severn River (New South Wales) and Dumaresq River, before reaching its confluence with the Weir River to form the Barwon River, west of Goondiwindi. In 1914, the current Goondiwindi Border Bridge was opened. It replaced a timber structure which was built in 1878. The Macintyre River descends 1,040 metres over its 319-kilometre course; passing near the towns of Glen Innes, Inverell, Ashford, Yetman, and Boggabilla. The flow of the river is impounded by Boggabilla Weir.
