The Condamine River, part of the Balonne catchment that is part of the Murray-Darling Basin, drains the northern portion of the Darling Downs, an area of sub-coastal southern Queensland, Australia. The river rises on Mount Superbus, South East Queensland's highest peak, on the western slopes of the Great Dividing Range, approximately 100 kilometres (62 mi) from the east coast of Queensland, and then flows north west across the Darling Downs, then west.
Course and features
The headwaters of the river rise on the slopes of Mount Superbus, part of the Main Range, before passing through Cambanoora Gorge. The river flows through the towns of and , while the tributary Gowrie Creek drains the slopes around Toowoomba. At Surat the Condamine turns to the south-west and becomes known as the Balonne River. The Condamine descends 516 metres (1,693 ft) over its 657-kilometre (408 mi) course, with a catchment area of 13,292 square kilometres (5,132 sq mi).
The Balonne River forks near Dirranbandi with a western branch being called the Culgoa River which, in turn, flows into the Darling River. The eastern branch of the Balonne River in turn branches again - into the Bokhara River on the right and the Narran River on the left (eastern) side. These rivers join with the Barwon River west of Brewarrina which also flows into the Darling River. Towns the Balonne passes through include St George, Dirranbandi and Surat. In this area Bungil Creek joins the Balonne River.
Water from the Condamine River is used for town water supply and for irrigation. Leslie Dam on Sandy Creek, a tributary of the Condamine, is the main water reservoir for Warwick. Talgai Weir is a small weir that can hold 640 megalitres (140×106 imp gal; 170×106 US gal) near Clifton. Other water storage facilities on the Condamine River include the Yarramalong Weir, Lemon Tree Weir, Loudoun Weir, Tipton Weir and the Cecil Plains Weir. The Condamine River is reduced to a series of drying ponds during droughts in Australia.
The Condamine River was named by Allan Cunningham in 1827 for Thomas de la Condamine, a former aide-de-camp to Governor Ralph Darling who became the colony's first Collector of Internal Revenue. Patrick Leslie was the first white settler in the area. He established Canning Downs in 1840, near Warwick.
The Condamine River and its catchment area were involved in the 2010–2011 Queensland floods. During the floods the river reached a record peak at Condamine of 15.25 metres (50.0 ft) and another peak of 14.67 metres (48.1 ft).
