Water Levels in Lake Eyre, Australia, Continue to Decrease – January 6th, 2011

Australia - December 26th, 2010

The ephemeral Lake Eyre is situated slightly northwest of the center of this image of central and southern Australia. The lake fills when rivers in Queensland and the area known as Channel Country flood.

Typically a 1.5 m (5 ft) flood occurs every three years, a 4 m (13 ft) flood every decade, and a fill or near fill four times a century. The water in the lake soon evaporates with a minor and medium flood drying by the end of the following summer.

Even in the dry season there is usually some water remaining in Lake Eyre, normally collecting in a number of smaller sub-lakes on the playa. Such salt flats can be observed here, and some remaining water can be seen in the southern sections of the lake. The amount of water appears to have decreased further since the last time the lake was observed, in early November (click here for previous article).
