Ilisus

Extracted from the Wikipedia article Ilisos.
The Ilisos or Ilisus (Greek: Ιλισός, ) is a river in Athens, Greece. Originally a tributary of the Kifisos, it has been rechanneled to the sea. It is now largely channeled underground, though as of June 2019 there were plans to unearth the river. Together with the neighbouring river Kifisos, it drains a catchment area of 420 km (160 sq mi).
