Australia - February 14th, 2011

The Thomson and Barcoo Rivers join to form the multi-channelled Cooper Creek, which flows vertically across the middle of this image. The flow of the creek depends on monsoonal rains falling months earlier and many hundreds of kilometres away in eastern Queensland.

Cooper Creek spreads out into a vast area of  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. Here the creek appears full, however, judging from the bright green color. Click here to see an image of the creek from about one year ago.

Lake Yamma Yamma (also know as Lake Mackillop) can be seen just west of Cooper Creek. When full, it covers an area of around 69,000 hectares. The lake is fed by the Yamma Creek. Here, the upper part of the lake is green and appears to be filling, while the lower appear appears white and is probably still a drier salt flat.
