Lake Pedder was once a natural lake, located in the
southwest of
Tasmania, Australia but the name is now used in an official sense to refer to the much larger artificial
impoundment and diversion lake formed when the original lake was expanded by damming in 1972 by the
Hydro Electric Commission of Tasmania.
The new Lake Pedder has an area of about 242 km² and it is considered to be the largest freshwater lake in Australia.
Wikipedia explains some of the huge controversy this "lake" caused.
