Tanjil River

The Tanjil River is a perennial river of the West Gippsland catchment, located in the West Gippsland region of the Australian state of Victoria.

Course and features
Formed by the confluence of the Tanjil River West Branch that drains the eastern slopes of Mount Toorongo from an elevation of 677 m and the northwestern slopes of the Mount Baw Baw from an elevation of 1485 m and the Tanjil River East Branch that drains the western slopes of Mount Baw Baw from an elevation of 1520 m, the Tanjil River rises below Hill End within the Great Dividing Range, in the Mount Tanjil Nature Reserve east of and southwest of. The river flows in a highly meandering course generally south, then south by east, joined by two minor tributaries, before reaching its confluence with the Latrobe River west of both Lake Narracan and in the Latrobe City local government area. The river descends 149 m over its 34 km course.

The Tanjil River is impounded by the Blue Rock Dam, that provides cooling water for thermal power stations sited in the Latrobe Valley, and to augment domestic water supplies. A small 2.4 MW hydroelectric power station is located on the river below the dam wall.

The Tanjil River sub-catchment area is managed by the West Gippsland Catchment Management Authority.
