The Buffalo River, a perennial river[4] of the North-East Murray catchment of the Murray-Darling basin, is located in the Alpine region of Victoria, Australia. It flows from the eastern slopes of the Buffalo Range in the Australian Alps, joining with the Ovens River west of .[3]
Formed by the east and west branches of the river, the headwaters of the Buffalo River rise in the Barry Mountains below Mount Selwyn and The Razor at an elevation exceeding above sea level. The east and west branches of the river reach their confluence within the Mount Buffalo National Park, where the watercourse becomes the Buffalo River. The river flows generally north, much of its course through the remote national park, joined by nine tributaries including the Catherine River and the Dandongadale River, before reaching its confluence with the Ovens River west of the town of Myrtleford and adjacent to the Great Alpine Road. The river descends over its 65km (40miles) course.[3]
The river is impounded by the Buffalo Dam that creates the 24000ML reservoir, called Lake Buffalo, that was completed in 1965 and supplies potable water to Myrtleford and irrigation of the Goulburn Valley.[5]
