Great Lake (Tasmania)
Fed by the Pine Rivulet and Breton Rivulet, the original natural freshwater lake, much smaller in size than its current 176-square-kilometre (68 sq mi) surface area, was expanded as a result of the 1922 construction of Miena Dam #2 at its southern outflow into the Shannon River.The hatching of thousands of caddis moths in early summer, attracted large numbers of trout and fishermen.[6] At 1,030 metres (3,380 ft) above sea level, the lake's uses include hydro-electric power, fishing, and tourism.[7] The nearby towns of Liaweenee and Miena are popular holiday shack destinations for local tourists, despite the area's reputation as being one of the coldest places in the generally mild-weathered state.During the winter months, when the weather is hardly conducive to camping, the population of these two small towns drops to two or three hundred.
