The largest lake on the Victorian Volcanic Plain is Lake Corangamite. It was formed when a river was blocked by a lava flow, like a lot of the lakes and swamps on the plain. But when is a lake a lake? Is a dry lake still a lake? Maybe here in Australia we need to invent a new word for a dry lake.
Lake Corangamite used to be 100 km long and 40 km wide when it first formed, but is now 33 km long and 20 km wide. But, it's only 2 metres deep! And that's when we've had a few normal years of rainfall. At the moment it's almost empty. The water has always been very salty, three times saltier than the sea, but now it's even saltier. The photo above was taken last week from the north looking south to Red Rock, a volcano near Colac on the south bank.
And the photo above was taken a year ago from Red Rock looking north.

I dunno, I kinda like the laconic Australian way of calling things 'lake'.
