Lake Mackintosh is a long man made lake related to the Pieman power development running north-south past Mount Farrell, adjacent to the town of Tullah in Tasmania.
It dams the Mackintosh River and Sophia River, then feeds Mackintosh Power Station through into Lake Rosebery.[1]
The lake was created in the 1980s and the main basin of the lake was originally a Button Grass swamp prior to inundation.
Lake Mackintosh in held by 2 dams, the main Mackintosh dam and the smaller Tullabardine Dam. The lake's deepest point is roughly 60m deep at the base of the main dam. It is one of the larger sized water impoundments of the Pieman power scheme [2]
The Murchison River is also fed into this lake through the Murchison Dam, to the south.
The Murchison Highway borders the lake to the West.
The Cradle Mountain-Lake St Clair National Park as a component part of the Tasmanian Wilderness World Heritage Area, has its western boundary lying to the east of the lake shores.
