Numeralla River

The Numeralla River, a perennial river that is part of the Murrumbidgee catchment within the Murray–Darling basin, is located in the Monaro region of New South Wales, Australia.

The name of the river is claimed to derive from an Aboriginal word meaning "valley of plenty", but Flavia Hodges has called this etymology "highly suspect".

Course
The river rises on the northern slopes of the Great Dividing Range, about 12 km east of the village of Nimmitabel, and flows generally north and west, joined by eight tributaries including the Kybeyan and Big Badja rivers before reaching its confluence with the Murrumbidgee River, south of Bredbo and about 18 km north of Cooma; descending 367 m over its 93 km course.

The river is a diverse ecosystem rich with many different animal species such as the uncommonly seen Wanderer's Kingfisher and the Kiora frog. Its native freshwater fish fauna had been entirely replaced by introduced trout species, now replaced by the introduced European carp species; a common situation in south-east Australia.

Alluvial gold was discovered in and along the river in 1858, with the diggings worked until 1868.
