About Chilika Lake

It is Asia’s largest and world’s second-largest brackish water lagoon after The New Caledonian barrier reef. A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. It has been listed as Ramsar Site as well as a tentative UNESCO World Heritage site. In 1981, Chilika Lake has designated the first Indian wetland of international importance under the Ramsar Convention.
