Chott el Djerid (

Arabic: شط الجريد Šoṭṭ el-Jarīd) also spelled Sciott Gerid and Shott el Jerid,[2][3][4][5] is a chott, a large endorheic salt lake in southern Tunisia. The name can be translated from the Arabic into English as "Lagoon of the Land of Palms".[6]

Geography

The bottom of Chott el Djerid is located between 10 and 25 meters (about 30 to 80 feet) below sea level.[7] The lake's width varies widely; at its narrowest point, it is only 20 km (12 mi) across, compared to its overall length of 250 km (160 mi). At times, parts of it appear in various shades of white, green and purple.[8] The narrow eastward inlet of the chott is also known as Chott el Fejej.

It is the largest

solar radiation, water evaporates from the lake. In summer Chott el Djerid is almost entirely dried up, and numerous fata morganas occur. It is situated at 33°42′N 8°26′E / 33.700°N 8.433°E / 33.700; 8.433 in the center-west of the country, between the cities of Tozeur and Kebili
.

During

tributaries of water can be seen discharging into the lake.[clarification needed][9]

Because the flooded area is very variable, values presented for the area of the lake (or its basin, which is almost always dry), can vary widely. Some sources provide values for surface area as high as 10,000 km². Similarly, figures given for altitude vary between 10 meters above and 25 meters below sea level.

Currently,

irrigation schemes
are being applied in the region to help eliminate salt from soils and increase the productive area.

Surrounding area

South of Chott el Djerid, the Grand Erg Oriental desert begins. The towns of Kebili and Douz are located south of the lake.

Access

The lake can be crossed by foot and even by car, but this is very dangerous since the salt crust is not always firm.

During winter, when the lake is full, it can be crossed by boat. Piles of salt at its edges are collected for salt production processing.[8]

Fauna

Relict populations of the West African crocodile persisted in the Chott el Djerid until the early 20th century.[10] Pink flamingos have been known to use the shores of the lake as nesting sites in springtime.[6]

Namesakes

Chott el Djerid is the namesake of the Jerid Lacuna, an

endorheic hydrocarbon lake on the Saturnian moon Titan. That lake is located at 66.7°N and 221°W and contains liquid methane and ethane[11]
instead of water.

Flooding project

There has been a growing interest in permanently connecting the Chott el Djerid to the

Mediterranean to create a Sahara Sea since the mid 2010s with the creation of the association Cooperation Road[12] which in 2018 obtained the approval of the Tunisian government.[13]

A similar project was also considered in the 19th and 20th century by

French Tunisia.[14]

In popular culture

The Lars Homestead set from Star Wars in Chott el Djerid.

Chott el Djerid was used as a filming location for the Star Wars series,[15] among others. It was also described in Jules Verne's last novel, Invasion of the Sea.

According to a legend, it was there that the

Greek goddess Athena was born.[16]

The lake is the setting of Frank Heller's book The Thousand and Second Night, An Arabesque.
