History.
In antiquity, the lake was called "Bistonis (Βιστονίς λίμνη), a great Thracian lake in the country of the Bistones, from whom it derived its name. The water of the lake was brackish and abounded in fish. The fourth part of its produce is said to have been granted by the emperor Arcadius to the convent of Vatopedi on Mount Athos. The river Cossinites emptied itself into the lake Bistonis, which at one time overflowed the neighbouring country and swept away several Thracian towns."
