Balonne River

At St George, the river is crossed by the Andrew Nixon Bridge which carries the Balonne Highway.

Beardmore Dam was formed by the construction of a weir in 1972 at the junction of the Maranoa and Balonne Rivers.

[6] When the dam is full the water backs up for 70 kilometres (43 mi) along the Balonne.

Downstream from Beardmore Dam is the Jack Taylor Weir, which was built in 1953.

Major Thomas Mitchell crossed the Balonne River on St George's Day, 23 April 1846.
