The Comet River is a river in Central Queensland, Australia.

Geography

Formed by the confluence of the Brown River and Clematis Creek, the Comet River rises in the Expedition Range, north of Expedition National Park and south of Rolleston. The river flows north, joined by seventeen tributaries, and splits as an anabranch on multiple occasions. The river flows through the Teatree Waterhole and Comet towards its confluence with the Nogoa River to form the Mackenzie River. The river descends 93 metres (305 ft) over its 294-kilometre (183 mi) course. The river is crossed by the Dawson Highway at Rolleston and the Capricorn Highway at Comet.^[2] The river traverses elevations between 144 and 1,243 m above mean sea level.^[1]

Water management

The Comet River Weir is the main water storage facility on the river, with a surface area of 13 hectares (32 acres) when full.^[3] In the late 1990s the river was proposed as the site for the Starlee Dam 16km north of Rolleston. The dam with a capacity of up to 1.3 million megalitres would have inundated the town of Rolleston, but was scrapped by the Queensland Government due to "significant and severe impacts" on the environment.^[4]
