Lake Iznik (Turkish: İznik Gölü) is a lake in the Province of Bursa, Turkey. It is around 32 km in length and 10 km in width with a maximum depth of about 80 m. The town of Iznik (historically known as Nicaea) lies at its eastern end. The lake's Ancient Greek name was Askania, (Ασκάνια).
In Greek mythology, during the Trojan War the region by the Lake İznik was held by the Phrygians, who sent troops to the aid of King Priam, led by the brothers Phorcys and Ascanius, sons of Aretaon as related in the Iliad.
Ascanius, son of Aretaon, should not be confused with Ascanius (son of Aeneas) or Ascanius (son of Priam), who also feature in legends of the Trojan War.
In the 1920s, the region was known for rice production.
Important Bird Area
The lake, which is in unprotected status, was declared by BirdLife International as an Important Bird Area in 1989 for its waterfowl species, which are threatened through development of İznik as recreational center and pollution.
