The river rises on the western slopes of the Great Dividing Range, north–east of Cooma at the junction of the Kybeyan and Gourock Ranges, and generally flows south and west, joined by three minor tributaries before reaching its confluence with the Numeralla River at the village of Numeralla; dropping 295 metres (968 ft) over its course of 32 kilometres (20 mi).[2]

Alluvial gold was discovered in and along the river in 1858, with the Big Badja diggings worked between 1861 and 1868.[3]
