The Serpentine Dam is part of Lake Pedder or, to use its technical name, the Huon Serpentine Impoundment. The dam was constructed in 1971 on the Serpentine River.
About two km west of Strathgordon, you pass the Lake Pedder lookout. This day, it was foggy and the lookout view was non-existent.
Continuing along Gordon River Road for another seven km, you reach the turnoff to the Serpentine Dam. From there, it’s a short drive to the boat ramp.
And from there, it’s another short drive to the dam wall.
This is a concrete-faced rockfill dam, which is basically a compacted rock wall that is made waterproof by a thin layer of concrete on the upstream face (the left side in this picture). The wall is 41.5 metres high at its highest point and 134 metres long. It contains 114 000 cubic metres of rockfill.
