Namoi River

The Namoi River, a major perennial river that is part of the Barwon catchment of the Murray-Darling basin, is located in the Northern Tablelands and North West Slopes districts of New South Wales, Australia.

The Namoi River rises on the western slopes of the Moonbi Range and Great Dividing Range, near Niangala, at the convergence of the Macdonald River and Boundary Creek, and flows generally west, joined by twenty-seven tributaries, including the Peel, Manilla and Mooki rivers, before reaching its confluence with the Barwon River, near Walgett.
