Location and features
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 1967 construction of the Miena Rockfill Dam at its southern outflow into the Shannon River. After Lake Pedder, the Great Lake is the state's second largest freshwater lake.
At 1,030 metres (3,380 ft) above sea level, the lake's uses include hydro-electric power, fishing, and tourism. Water from the lake flows into Poatina Power Station to generate hydro-electric power.
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. Parts of the lake surface have frozen during July in some years.
The Lake Highway or Highland Lakes Road runs along the west side of the lake and is sometimes snowed under in winter.
