The Lake Machattie area is located in the southwestern part of Queensland and covers about 900 km2. The area is on average replenished with water from the Georgina River every 3 years and contains three lakes: Lake Machattie, Lake Mipia, and Lake Koolivoo. These lakes become gradually more saline during the dry summer period. The region is a designated Important Bird and Biodiversity Area (IBA) and harbours among others the Australian Pelican, Straw-necked Ibis, and the Sharp-tailed Sandpiper. The 100 m image shows the lake during the dry season. The red areas indicate the various branches of the Georgina River, while the light-blue areas denote salt planes.
