The Arthurs Lake is a man-made reservoir located in the Central Highlands region of Tasmania, Australia.

[3] The principal purpose of the lake is to support the generation of hydroelectricity.

It is located in the Central Highlands, north of Lyell Highway, east of Great Lake.

Some of the pumping energy is recovered by Tods Corner Power Station.

In 2017, Irrigation Tasmania installed a floating safety barrier to prevent fishing boats accessing the hydro intake pipe in this very popular fishing lake.
