Lake Pedder Extinctions
The Lake Pedder earthworm (Hypolimnus pedderensis) is only known by the type specimen collected from a beach on Lake Pedder, Tasmania in 1971. After the flooding of the lake, this invertebrate was never seen again. A 1996 survey that sought to determine whether the species still existed in the area failed to find any examples. Since 2003 the Lake Pedder Earthworm has been listed as extinct on the IUCN Red List of Threatened Species.
An extinction claimed to have occurred after the flooding is that of the Lake Pedder planarian (Romankenkius pedderensis), an endemic flatworm. Since 1996 this invertebrate has also been listed as extinct on the IUCN Red List of Threatened Species. In 2012 the continued existence of this species was reported.
The Pedder galaxias, an Australian freshwater fish, is considered extinct in its natural habitat of Lake Pedder and its tributaries, although it still exists in captivity and in two translocated populations, one at Lake Oberon in the Western Arthurs mountain range. and one at a modified water supply dam near Strathgordon.

Famous quotes containing the word lake:
“They who know of no purer sources of truth, who have traced up its stream no higher, stand, and wisely stand, by the Bible and the Constitution, and drink at it there with reverence and humility; but they who behold where it comes trickling into this lake or that pool, gird up their loins once more, and continue their pilgrimage toward its fountain-head.”
—Henry David Thoreau (1817–1862)
