Course and features
The Mooney Mooney Creek rises southeast of Central Mangrove below Peats Ridge, and flows generally south before reaching its confluence with the Hawkesbury River at the locality of Mooney Mooney. The river descends 294 metres (965 ft) over its 32-kilometre (20 mi) course.
Although called a creek, the watercourse is designated as a river, and is impounded by the Mooney Mooney Upper Dam, below Mount White. The Pacific Motorway, via the Mooney Mooney Bridge, and the Central Coast Highway crosses the river, both east of the Calga interchange.
