Lake Eyre , Australia


Lake Eyre is the lowest point in Australia, at approximately 15 m (49 ft) (AHD) below sea level, and, on the rare occasions that it fills, it is the largest lake in Australia and 18th largest in the world. It is the focal point of the vast Lake Eyre Basin and is found in South Australia, some 700 km (435 mi) north of Adelaide.

The lake was named after Edward John Eyre who was the first European to sight it in 1840. It is located in the deserts of central Australia, in northern South Australia. The Eyre Basin is a large endorheic system surrounding the lakebed, the lowest part of which is filled with the characteristic salt pan caused by the seasonal expansion and subsequent evaporation of the trapped waters. Even in the dry season there is usually some water remaining in Lake Eyre, normally collecting in a number of smaller sub-lakes within its margins.

During the rainy season the rivers from the north-east part of the Lake Eyre basin (in outback (south-west and central) Queensland) flow towards the lake through the Channel Country. The amount of water from the monsoon determines whether water will reach the lake and if it does, how deep the lake will get.

The -15 m altitude usually attributed to Lake Eyre refers to the deepest parts of the lake floor, in Belt Bay and the Madigan Gulf. The shoreline lies at -9 m
