Poatina Hydroelectric Power Station

The Miena Rockfill Dam is a rock-filled embankment dam across the Shannon River, located near Miena, in the Central Highlands region of Tasmania, Australia. Completed in 1967, the dam flooded the Great Lake, a natural freshwater lake, and created an expanded, yet shallow, reservoir, established for the purpose of generation of hydroelectricity via the adjacent Poatina Power Station, a conventional hydroelectric power station. The dam, its reservoir, and the power station are owned and operated by Hydro Tasmania.
