Lakes Kaban, the system of lakes in Kazan, Republic of Tatarstan, Russia, includes Nizhny (Blizhny) Kaban, Verkhny Kaban, and Sredny Kaban. With an area of 1.86 square kilometers (0.72 sq mi), it is the biggest lake in Tatarstan.
It is connected with the Kazanka River by the Bolaq channel and a subterranean channel from Bolaq-Qazansu. It is also connected with the Volga river by the city's sewage system.
The Thousandth Anniversary of Islam Mosque is situated at the bank.
The medieval Volga Bulgarians' graves which date back to 12-13th century were founded on the banks of Arğı Qaban.
One legend claims that, in the days before the Khanate of Kazan fell, the Khans threw all their valuables into the lakes.
Another legend about the origin of the lakes names claims that, at the Mongol invasion of Volga Bulgaria, the Bulgarian prince Qabanbäk, escaped from Bilär city (or in Bolghar), fled to the banks of the lake and built a castle. Another version is that he founded İske Qazan.
Tatar myth also places Zilant, who had been transformed to Diü, as the ruler of the mythological Underwater Kingdom of Qaban.
