The Trevallyn Dam is a dam in the north of the Australian state of Tasmania .
It is located on the western outskirts of the city of Launceston on the South Esk River . Its surface is 1.48 km² and its water content is 12.33 million m³ when it is fully flooded.
The Trevallyn Dam, a gravity dam , was built in 1955, is 177 m long and has a volume of 61,000 m³. The crown height is 33 m, the outlet height 26.8 m.
At the dam, most of the water from the South Esk River is channeled into a two-mile tunnel to the Trevallyn Power Station , where electricity is generated for the city of Launceston and its surroundings. From there it is forwarded to the Tamar River . Only the overflow water flows through the Cataract Gorge , which used to be frequently flooded, the old river bed of the South Esk River, into the Tamar River.
