Mummel River, a watercourse of the Manning River catchment, is located in the Northern Tablelands and Mid North Coast districts of New South Wales, Australia.
Mummel River rises on the eastern slopes of the Great Dividing Range, below Mount Sugarloaf, southeast of Walcha and flows generally south by west, southeast, and then south southeast, joined by one minor tributary, before reaching its confluence with the Cooplacurripa River, north of Giro, northwest of Taree. The river descends over its course.[1] There are two fault lines that are near the path of the river.[2]
