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 the site for a proposed new dam, although it was never built.
