Namak Lake (Daryacheh-ye Namak) (Persian for Salt Lake) is a salt lake in Iran. It is located approximately east of the City of Qom at an elevation of above sea level. The lake has a surface area of about 1800 km², but most of this is dry. Water only covers 1 km². The lake only reaches a depth between 45 centimetres to 1 metre. The most important water supply is the river Qom. The lake is a remnant of the Paratethys sea, which started to dry from the Pleistocene epoch, leaving lake Urmia and the Caspian sea and other bodies of water.
