Lake Hazar (Turkish: Hazar Gölü; Kurdish: Gola Hezarê; Armenian: Ծովք լիճ, romanized: Covk‘ lič) is a rift lake in the Taurus Mountains, 22 km southeast of Elazığ, notable as the source of the Tigris.

[1][2] Scientists found 4,000-year-old archaeological traces of a city, estimated to have been submerged since 1830, below the lake.

Turkey wanted to register this historic 'Sunken City' in eastern Anatolia as a UNESCO World Heritage Site.

[3] Ebubakar Irmak, mayor of Sivrice, dove into the lake in 2017 and found the remains of churches, walls of a castle, pots, pottery and glazed plates of the citadel with traces of the Seljuk, Byzantine and Ottoman eras.

[4][5] In 2019, amphora tombs were found in the sunken city.
