Lake Tuz
Lake Tuz is the second largest lake in Turkey and one of the saltiest lakes in the world. Its Turkish name, Tuz Gölü, means "Salt Lake", and in summer much of it turns into a white crust of salt.

The story behind it
Lake Tuz lies in the middle of Turkey, in one of the driest parts of the country. For most of the year it is very shallow – only about 40 centimetres deep – and even at its deepest it is only about 1.5 metres. No river flows out, so the water evaporates in the sun and leaves its salt behind. In summer much of the lake dries up, and a layer of salt about 30 centimetres thick appears. Three salt works collect this salt, and about two thirds of the salt used in Turkey comes from here. The lake is also home to Turkey's largest colony of greater flamingos, which raise their chicks here. That is why it has been a specially protected area since 2001. In very dry years the whole lake has dried out, for example in 2021.
Find it on the globe
Lake Tuz is there as a small blue dot with its name, right on the water. From far away the planet is only a blue ball; detail arrives as you zoom in, and this one appears once you are close enough. Open it on the globe.
It sits at its real coordinates, not near them — the same numbers listed in the facts above. Switch off the layer for this kind of place and it disappears again; the buttons for that are down the right-hand edge.
Questions children ask
How big is Lake Tuz?
Lake Tuz covers about 1 665 km² when it is full; some sources give about 1 600 km². In summer much of it dries up, so its size changes a lot during the year.
Is Lake Tuz the largest lake in Turkey?
No, Lake Van is larger, so Lake Tuz comes second. But Lake Tuz is one of the saltiest lakes in the world.
What is the salt from Lake Tuz used for?
Three salt works collect the salt that is left behind when the water evaporates. About two thirds of the salt used in Turkey comes from this lake.
