Umm al Binni lake

Former lake in Maysan Governorate

Umm al Binni lake is a mostly dry lake within the Central Marshes in Maysan Governorate in southern Iraq. The 3.4 km (2.1 mi) wide lake is approximately 45 km (28 mi) northwest of the Tigris–Euphrates confluence. Because of its shape, location, and other details, it was first conjectured by Sharad Master, a geoarchaeologist, to represent an impact crater. However, these claims have been disputed, with other studies finding subsidence of the underlying rock a more plausible explanation.
