Wular Lake is a famous lake located in the Bandipur district of Jammu and Kashmir. It is one of the largest fresh water lakes in India.
Until a few years back Wular used to be the largest fresh water lake in Asia, but now it is only a green area.
It is said that the word 'Wular' is probably a corruption of 'Ullol'. The ancient name of the lake was 'Mahapadmasar'.
This lake is spread over an area of 30 to 260 square kilometers.
Wular Lake is also very important from the point of view of tourism.
The Jhelum River forms its temporary delta in it.
At present, its area is decreasing rapidly.
The island is situated in the northeast corner of Wular Lake. It is called 'Jainul Lank'  in Kashmiri language. It is an artificial island, which was built by Zainul Abadin, the ruler of Kashmir in 1444 AD. Zainul Abadin was known for his religious tolerance and is fondly remembered by Hindu and Muslim Kashmiri people as 'Bud Shah'.
According to the 15th-century Kashmiri historian Jonraj, the island was built by Bud Shah to shelter sailors from stormy conditions in the Wular Lake. Ruins still exist on it. At the time the island was built, Wular was slightly larger and the island was in the middle of the lake. Gradually the Wular Lake dried up and shrunk from one side and the island now appears to be a corner.
