Manilla River

Manilla River, a perennial stream that is part of the Namoi catchment within the Murray–Darling basin, is located in the Northern Tablelands district of New South Wales, Australia.

The stream (called a river) rises south–west of Barraba on the northern slopes of the Baldwins Range and drains a portion of the hill country on the western side of the New England highlands and the southern slopes of the Nandewar Range; flowing generally north and east and to the town of Barraba. During its course, the stream is joined by five minor tributaries, and flows in a southerly direction towards its confluence with the Namoi River at the town of Manilla; dropping 496 m over its length of 138 km.

The name of the river is derived from the Australian Aboriginal words of manilla, maneela, or muneela meaning "winding river" or "round about".

Approximately 10 km north of Manilla, Split Rock Reservoir, on the Manilla River, provides one of the main water storages for flood control and irrigation in the Namoi River basin.
