The bottom of Chott el Djerid is located between 10 and 25 meters below sea level. Roughly in the shape of a wolf, with a width of 20 km (12 mi) at its narrowest point, it reaches 250 km (160 mi) in overall length. At times, parts of it appear in various shades of white, green and purple. The narrow eastward inlet of the chott is also known as Chott el Fejej.
It is the largest salt pan of the Sahara Desert with a surface area of over 7,000 km2 (some sources state 5,000 km2). The site has a typical hot desert climate. Due to the harsh climate with mean annual rainfall of below 100 mm and daytime temperatures sometimes reaching 50 °C or more during summer with dense solar radiation, water evaporates from the lake. In summer Chott el Djerid is almost entirely dried up, and numerous fata morganas occur.
The lake can be crossed by foot and even by car, but this is very dangerous since the salt crust is not always firm.
Relict populations of the West African crocodile persisted in the Chott el Djerid until the early 20th century.
Chott el Djerid is the namesake of the Jerid Lacuna an Endorheic hydrocarbon lake on the Saturnian moon Titan. That lake is located 66.7°N and 221°W on Titan's globe and involves liquid methane and ethane, instead of water.
