Also at the southern end of the Lake Pedder, the Scotts Peak Dam impounds the upper reaches of the Huon River.

Built on a foundation of rock and soil, the Scotts Peak Dam wall was constructed with 584 thousand cubic metres (20.6×10^6 cu ft) of rockfill and faced with asphalt.

At 100% capacity the dam wall holds back 2,937,930 megalitres (103,752×10^6 cu ft) of water.

A small greens movement was formed it response, which mobilised in the 1980s to stop the proposed Franklin River Dam.

[6] In the 2008 edition of Ticklebelly Tales engineers associated with the dam acknowledge that there were issues leaks as soon as it was built.
