Lake Margaret (Tasmania)
BW
The Lake Margaret is a reservoir in the west of the Australian state of Tasmania. It is located high up on the northern slopes of Mount Sedgwick, a mountain in the West Coast Range. The Yolande River rises in the lake.
Dam
The dam was completed in 1918. He was the first gravity dam in Tasmania and was built of concrete with conglomerate " plums ". The dam is 17 m high and has a crest length of 243 m. The volume of the dam is 6,000 cubic meters. In 1974, she was reinforced by the integration of pre-stressed concrete anchors and grouting of open connections.
Power station
Simultaneously with the dam, the Lake Margaret Power Station and a settlement that was also called Lake Margaret emerged. The power plant supplied electricity for the nearby mines and settlements of the Mount Lyell Mining and Railway Company. The mine and railway company was established in Queenstown. In the 1990s, Hydro Tasmania took over the power plant operation.
Catchment area
Several smaller lakes - some with their own name, others not - are above the reservoir. Land exchange between the current operators of the power plant and the State Government of Tasmania made sure the catchment area of the dam now Hydro Tasmania is one, while the surrounding country either to Tyndall Regional Reserve or Lake Beatrice Conservation Area - part - both state protected areas.
The two southern outfall originate on the slopes of Mount Sedgwick, the western of which flows through the Lake Barnables (less than 1 km east of Lake Margaret ) and Lake Phillip. The eastern outfall originates on a lake with no name and flows over Lake Polycarp, the Peter Lake, the Lake Paul and Apollos Lake in the Lake Phillip.
The northern outfall flows through the Lake Monica, Lake Myra, Lake Magdalene ( 782 m), the Martha Lake (757 m ), and finally the Lake Mary (732 m ) before it ends in the Lake Margaret.
The larger and slightly lower natural lake located this area lies southeast of Mount Sedgwick and is called Lake Beatrice.
