Cluny Dam

Built by the Hydro Electric Corporation (TAS) in 1967, the concrete dam wall is high and long. When full, the reservoir has capacity of and covers , drawn from a catchment area of . The uncontrolled spillway has a flow capacity of . The reservoir receives water from the Repulse Dam. == Hydroelectric power station ==

Part of the Derwent scheme that comprises eleven hydroelectric power stations, the Cluny Power Station is the tenth power station in the scheme. The power station is located aboveground below the Cluny Lagoon. The facilities at the Cluny Power Station are simple and include the dam, intake structure with intake gate designed to cut off full flow, a short penstock which is integral with the dam, power station building, generator equipment and associated facilities. The power station was commissioned in 1967 by the Hydro Electric Corporation and has a single Boving Kaplan-type turbine with a generating capacity of of electricity. Within the station building, the turbine has a four-bladed runner and concrete spiral casing. Pre-stressed cables passing through the stay vanes anchor the spiral casing and form part of the station foundation. No inlet valve is installed in the station. The station output, estimated to be annually, is fed to TasNetworks' transmission grid via an 11 kV/220 kV Siemens generator transformer to the outdoor switchyard. Water discharged from the Cluny Power Station flows into the River Derwent. == See also ==
