Clark Dam Wall - TAS

Part of the Derwent scheme that comprises eleven hydroelectric power stations, the Butlers Gorge Power Station is the first station in the scheme. The power station is located above ground at the foot of the concrete arched Clark Dam across the River Derwent that forms Lake King William. Water from the lake is fed to the power station, coupled to one of two discharge regulating valves to ensure water flow to Tarraleah Power Station located further downstream.
