Largest desert lake

Lake Turkana, in the Great Rift Valley, Kenya, has a surface area of 6,405 km² and an average depth of 30.2 m. It is the fourth largest salt lake in the world and is fed by the Omo, Turkwel and Kerio rivers. There is no outflow from Lake Turkana and the only method of water loss is by evaporation.

A desert Lake is an area of nominally desert land with a substantial ability to hold water, fresh or saline, when fed by either rainfall or a water course. A desert in this description is nominally anywhere that less than 250 mm (9.8 in) of precipitation falls annually.

There are two forms of desert lake. In permanent desert lakes, such as Turkana, the lake is fed by multiple watercourses from rainfall removed from the local area. In temporary desert lakes, such as salt pans, annual rainfall may temporarily fill a depression in the landscape only for evaporation to later remove the water.
