Location of the Wimmera River mouth in Victoria

The Wimmera River, an inland intermittent river of the Wimmera catchment, is located in the Grampians and Wimmera regions of the Australian state of Victoria. Rising in the Pyrenees, on the northern slopes of the Great Dividing Range, the Wimmera River flows generally north by west and drains in Lake Hindmarsh and Lake Albacutya, a series of ephemeral lakes that, whilst they do not directly empty into a defined watercourse, they form part of the Murray River catchment of the Murray-Darling basin.

The Wimmera River rises in the Great Dividing Range below Elmhurst, between Ararat and Avoca, and flows generally north and west, through Glenorchy, Horsham, Dimboola and Jeparit, also forming the eastern boundary of the Little Desert National Park. It is joined by fourteen minor tributaries, including the Mackenzie River, before reaching its mouth at Lake Hindmarsh, near Jeparit. The river descends 220 metres (720 ft) over its 278-kilometre (173 mi) course.
