Lake Rosebery is a large, man-made lake in the West Coast area of Tasmania, Australia. It's not a natural lake but a special type of reservoir created to store water. This lake is found in the northern part of Tasmania's West Coast Range. It gets its water from two rivers, the Mackintosh River and the Murchison River, which were dammed to form the lake.
Building Lake Rosebery
How the Lake Was Formed
Lake Rosebery was created when the Bastyan Dam was built across the Pieman River in 1983. This dam was constructed by the Hydro-Electric Commission, which is a company that manages Tasmania's water and power.
The dam helped create a huge reservoir, which is another name for a man-made lake. This reservoir, Lake Rosebery, can hold about 123,520 megalitres of water. A megalitre is a million litres! The lake's surface area is around 744 hectares. It collects water from a large area of land, called a catchment area, which covers about 1,397 square kilometres.
Where to Find Lake Rosebery
The lake is located close to a small village called Tullah. If you were to visit the area, you would find that the old Emu Bay Railway line and the Wee Georgie Wood Railway line run very near to the lake's edge.
