Harrietville was established as a mining settlement in 1852, and remnants of this history are scattered around town. The most prominent is the dredge hole, which was created by the Tronoh, one of the world's largest mechanical dredges, between 1939 and 1947.
When mining operations stopped, the dredge was shipped off to Malaysia, and a large artificial lake was left behind. Over the years, this has been turned into a scenic tourist destination where visitors can go swimming, diving, fishing or canoeing. You’ll find the lake off the Feathertop track, on Dredge Hole Lane.
