Lake Corangamite is Victoria’s largest natural lake located near Colac in South West Victoria, Australia. The lake is listed on the Ramsar list of wetlands of international importance is very important to the local environment and local bird species. The lake is surrounded by rocky outcrops from volcano activity giving the region the name 'Lakes & Crater Country'. It was this volcanic activity which formed the craters that comprise the lake.
Although, owing to the very low runoff ratios typical of temperate Australia, flow into the lake is extremely variable and negligible in the driest years, Lake Corangamite has never been completely dry since European settlement. During the wet decade of the 1950s the lake came close to becoming an open lake ie. one with an outlet to the sea. It is believed that for centuries prior to the 1840s rainfall and runoff were similar to those of the 1950s and the lake may not have been an endorheic basin.
The salinity of Lake Corangamite under normal water conditions is about equal to that of the Red Sea and is somewhat greater than that of the oceans, though not nearly so high as the Dead Sea or Great Salt Lake.
