Lakes Tuz, Beyşehir and Eğirdir in Turkey

Turkey - August 30th, 2010

Clouds hang over the Strait of Kerch and Istanbul, while the skies over the rest of the country are clear. Many islands can also be seen off the western coast, as well as the island country of Cyprus to the south.

Several lakes can be seen on the Turkish mainland. The large white area at the center left is Lake Tuz, a saline lake and the third largest body of water in the country. Southwest of Lake Tuz are Lake Beyşehir (bright turquoise in color) and Lake Eğirdir (slightly darker and further west). Both of these are freshwater lakes and are situated in the Turkish Lakes Region.

Lakes Eğirdir (left) and Beyşehir (right), in the Göller Bölgesi (Lakes Region) of Turkey appear bright green in contrast with the darker colors of the surrounding Western Taurus Mountains.

Lake Beyşehir has a surface area of 650 km², making it the third largest lake in Turkey and the largest freshwater lake in the country. It is used for irrigation and its water level tends to fluctuate.

Lake Eğirdir is slightly smaller in terms of surface area, at482 km2. This makes it the fourth largest lake in Turkey and the country’s second largest freshwater lake.

South of the lakes, along the Mediterranean coast of southwestern Turkey, is the city of Antalya, the capital of Antalya Province. Situated on coastal cliffs, Antalya is surrounded by mountains.

The Taurus mountain range of southern Anatolia runs parallel to the Mediterranean in an east-west direction, resulting in the formation of narrow coastal plains surrounded by mountains on three sides and the sea on the fourth. Some parts of the coast feature mountains plunging sharply into the sea, forming small natural bays and peninsulas.

Antalya is situated on one such plain where the mountains recede from the shore, consisting of two flat areas formed of travertine rock at a mean height of 35 metres (115 ft); the town center is located on the rocky plain closest the coast, with urban sprawl extending to the Kepezüstü Plain further inland.

Lakes of varying sizes can be seen across this part of southern Turkey, near the Mediterranean Sea, known as the Göller Bölgesi or Lakes Region.

The large, greenish lake near the center is Lake Beyşehir, with a surface area of 650 km². This freshwater lake is used for irrigation, which has been causing reductions in its water level and thus threatening the fish and plankton inhabiting it.

The other large freshwater lake west of Beyşehir is Lake Eğirdir, with an area of 482 km². Southwest of Eğirdir is the dark blue Lake Burdur, whose surface area is 250 km² .

Unlike its two larger neighbors, its waters are saline. Water level in the lake fluctuates; its maximum depth has been variously reported at between 50 and 110 m. Lake Burdur is also an important wetland site for many bird species and is designated a Ramsar site.

The Göller Bölgesi (Lakes Region), in the Western Taurus Mountains of Turkey’s Mediterranean Region, has many freshwater lakes.

Eğirdir is the name of a lake (dark blue, left) and of the town situated on the shore of that lake in Turkey. With an area of 482 km2 it is the fourth largest (second largest freshwater) lake in Turkey.

The large, turquoise lake on the right is Lake Beyşehir. It has an area of 650.00 km² and is 45 km long and 20 km wide. It is a freshwater lake, used for irrigation, whose water level often fluctuates.

Scientists from Turkey’s Middle East Technical University have estimated that if the amount of water taken from the lake is doubled, its area will be reduced by one third, and the water level will be lowered by 6-10 m.

As the number of species in a given area is directly related to the area’s size, as a result of this reduction in size, in Lake Beysehir the number of naturally occurring fish species will decrease from 8 to 7, phytoplankton species from 52 to 45, etc.

The smaller turquoise lake above Beyşehir is Lake Akşehir, a tectonic freshwater endorheic lake also used for irrigation. The lake is fed by the Eber Channel, five larger streams from the Sultan Mountains and many smaller streams. The lake salinity increases towards the middle and northern parts due to underground spring waters.

Lakes in Southern Turkey - November 25th, 2008

Lakes in Southern Turkey - November 25th, 2008

Several lakes in the Lakes Region of southwestern Turkey are visible in this image.

The largest lake, on the far right, is Lake Beyşehir. It is a large freshwater lake whose water level often fluctuates. Lake Beyşehir is used for irrigation, although it is also a national park. In the image, we can see that sediments have turned parts of it a greyish tan color, while algae has made other parts green.

To the left of Lake Beyşehir is Lake Eğirdir. With an area of 482 km2 it is the fourth largest (second largest freshwater) lake in Turkey. It has some grey-tan sediments as well, although it seems to contain more blue-green algae.

Southwest of Lake Eğirdir we have Lake Burdur which, unlike the previous two, is a large saline lake. Water level in the lake fluctuates, and it is also an important wetland site for many bird species.

Finally, to the left of Lake Burdur we can see the outline of Lake Acıgöl (literally “the bitter lake” in Turkish). Its surface area varies greatly through the seasons, with 100 km² in spring and 35 km² in late summer, with a maximum depth of 1.63 m. In the image, the surface level appears low around the edges, with a deeper green pool in the center.

Lake Acıgöl, fed primarily by high-sulfate springs issuing from a fault line on its south side, is notable for its sodium sulfate reserves. It is estimated to contain 12.5 million mt of sodium sulfate in the surface and in the subsurface brine. These reserves extensively used in the industry and Turkey’s largest commercial sodium sulfate production operations are based here.
