Meandering Ephemeral Channels of Cooper Creek, Australia28.5S 137.9E
Cooper Creek is one of the most famous and yet least visited rivers in Australia. It rises west of the Great Dividing Range on low ground as two central Queensland rivers, the Thomson and the Barcoo, about 500 kilometres inland from Rockhampton.
Cooper Creek spreads out into a vast area of meandering ephemeral channels, making its way roughly south into the far south-west corner of Queensland before turning due west into South Australia towards Lake Eyre.
In most years, it is absorbed into the earth, goes to fill channels and the many permanent waterholes, or simply evaporates without reaching Lake Eyre. In very wet years, however, such as this one, it manages to flood the entire Channel Country and reaches the lake.
