Formed by the
confluence of the
Fury River and Mackintosh Creek, the Mackintosh River rises below Mount Remus, part of the northern section of the
West Coast Range. The river flows a short distance, through what is now known as
Lake Mackintosh, joined by four tributaries including the
Sophia River and
Southwell River, emptying into the Pieman River. The Mackintosh River is impounded by the
Mackintosh Dam, the site of the adjacent
hydroelectric power station that forms part of the
Hydro Tasmania-operated
Pieman River Power Development. The river descends over its
course. The southern portion of the catchment has a very narrow separation from the adjacent Murchison River, where the Sophia River is the main river. The northern side of the Sophia river catchment, a creek known as White Hawk, drains ground with features known as Granite Tor, and High Tor, which lie due east of . The northern Mackintosh catchment has a number of named tributaries. From the orientation of Mount Romulus, Fury River which originates near Barn Bluff, is the main eastern tributary. Mount Remus is drained to the south by Schist Creek which flows into the Fury River, and to the west, Devils Ravine. In the north east of the catchment area, Mayday Mountain is drained by
Belvoir River. The north west area the Southwell River drains the eastern slopes of Mount Charles, which is north east of Mount Black. The river name is used in cartography of the area, with the river name being allocated to current maps, as well as significantly early maps of the region. ==See also==
