Lake Xynias

Lake Xynias or Xyniada (Λίμνη Ξυνιάς/Ξυνιάδα) was a lake in Central Greece.

The lake lay in a caldera of Mount Othrys, and measured approximately 5 km × 7 km, with a depth of 5 m. It was named after the nearby city of Xyniae. In the Middle Ages, it received the Slavic name Ezeros, after which the city was also renamed.

The lake was drained in 1936–42 to create arable farmland.
