This is Lake Urmia in East Azarbaijan province of Iran, which has now dried up and turned into a salt desert after centuries.
Years ago, this ship used to transfer many passengers to several habitable islands in Lake Urmia.

Lake Urmia had 102 big and small islands, some of which were habitable and life was going on in them, and after the lake dried up, it became uninhabited.

Lake Urmia is an endorheic salt lake in Iran. The lake is located between the provinces of East Azerbaijan and West Azerbaijan in Iran, and west of the southern portion of the Caspian Sea. At its greatest extent, it was the largest lake in the Middle East and the sixth-largest saltwater lake on Earth, with a surface area of approximately 5,200 km2 (2,000 sq mi), a length of 140 km (87 mi), a width of 55 km (34 mi), and a maximum depth of 16 m (52 ft).

Since 2005, Lake Urmia started to dry up due to unprincipled dam constructions, and now less than 2% of it remains.
