Lake Yliki

Lake Yliki ( "Yliki", Ancient Greek: Ὑλικὴ "Hylike", Latinised as "Hylica") is a large natural lake of Boeotia, central Greece. Situated 8 km north of Thebes at 78 m elevation, it has been an important source of drinking water for the Athens agglomeration since 1958. It is surrounded by low mountains, which separate it from the drained Lake Copais.

Some scenes of French-singer Indila's music video "S.O.S" were filmed at the lake.
