Sophia, Fury, Southwell, and Brougham rivers and the Mackintosh and Tullabardine creeks. The reservoir's outflow feeds the Mackintosh Power Station through
Lake Rosebery. The
Murchison River feeds into Lake Mackintosh through the
Murchison Dam, to the south. The reservoir's deepest point is approximately deep at the base of the main dam. It is one of the larger sized water impoundments of the Pieman power scheme. The main basin of the reservoir was originally a
Button Grass swamp prior to inundation. 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. The
Murchison Highway borders the reservoir to the west. == Hydroelectric power station ==
