Wular Lake (also spelt Wullar) is a large fresh water lake in Bandipore district in the Indian state of Jammu and Kashmir. The lake basin was formed as a result of tectonic activity and is fed by the Jhelum River. The lake’s size varies from 12 to 100 square miles (30 to 260 square kilometers), depending on the season.The lake is one of six Indian wetlands designated as a Ramsar site. However it faces environmental threats including the conversion of large parts of the lake’s catchment areas into agriculture land, pollution from fertilizers and animal wastes, hunting of waterfowl and migratory birds and weed infestation in the lake itself.The Tulbul Project is a “navigation lock-cum-control structure” at the mouth of Wular Lake.
