Chott Melrhir (Arabic: شط ملغيغ) also known as Chott Melghir or Chott Melhir is an endorheic chott-kind of salt lake in northeastern Algeria. It is the westernmost part of a series of depressions, which extend from the Gulf of Gabès into the Sahara. They were created between Miocene and Early Pleistocene as a result of compression accompanying the formation of the Atlas Mountains.[5] With the maximum area of about 6,700 km2 (2,600 sq mi), it is the largest lake in Algeria.[3] It lies almost entirely below sea level and contains the lowest point in Algeria, −40 meters (−130 feet).[6] Its size varies over the year and is usually larger than 130 km (81 mi) from east to west.[7] The nearby cities are Biskra (60 km north-west), El Oued and Touggourt (85 km south).[8]
