Lake Mackintosh is a 17.5-kilometre-long (10.9 mi)reservoir with a surface area of 3,100-hectare (7,700-acre) that forms part of thePieman power development running north–south past Mount Farrell, adjacent to the town ofTullah inTasmania.
Fed by the damming of theMackintosh,Sophia, Fury, Southwell, and Brougham rivers and Mackintosh Creek, water from the lake feedsMackintosh Power Station throughLake Rosebery.[2]
The lake was created in the 1980s and the main basin of the lake was originally aButton Grass swamp prior to inundation.
Lake Mackintosh is impounded by two dams, the main Mackintosh Dam and the smaller Tullabardine Dam. The lake's deepest point is roughly 60 metres (200 ft) deep at the base of the main dam. It is one of the larger sized water impoundments of the Pieman power scheme.[3]
TheMurchison River feeds into Lake Mackintosh through the Murchison Dam, to the south. TheMurchison Highway borders the lake to the west.
TheCradle Mountain-Lake St Clair National Park as a component part of theTasmanian Wilderness World Heritage Area, has its western boundary lying to the east of the lake shores.
