Geosite Description: This panoramic view looks south along a relatively dissected part of the West Coast Range, in an area where, unusually, drainage has cut through the range from west to east. Lake Plimsoll was created in 1994 by damming of the Anthony River by the Hydro-Electric Commission, and was named for Sir James Plimsoll, Governor of Tasmania for the period 1982-1987. This was the last major dam constructed by the Commission. The water is taken by a 7 km long tunnel to a power station on the banks of Lake Murchison. The lake is stocked with brook trout and is a popular fishing venue.
Lake Selina is one of a number of glacial lakes along the West Coast Range. Some of these were formed in the most recent glacial phase of the last (Pleistocene) Ice Age, e.g. by damming behind moraines, but others, such as Lake Selina, relate to earlier glacial phases when ice was more extensive.
