Koronia Lake

Lake Koroneia is a lake in the heart of the Thessaloniki regional unit in the Mygdonian basin in Greece. It is also known as Lake Agios Vasileios after the village Agios Vasileios and as Lake Langadas after the town Langadas, and is located about 14 kilometres east of Thessaloniki city centre. The motorway Egnatia Odos passes along the north side of the lake, and the old Greek National Road 2 passes along the south side. The lake is shared by the municipalities Langadas and Volvi.

A million years ago, Lake Koroneia along with Lake Volvi and all of the Mygdonian basin was a single large lake. Since then, its area has declined and the distance from neighboring Lake Volvi is becoming larger. In the 1950s, Koroneia was among the lakes of Greece with the biggest fish production.
