Chilika Lake is a brackish water lagoon, spread over the Puri, Khurda and Ganjam districts of Odisha state on the east coast of India, at the mouth of the Daya River, flowing into the Bay of Bengal, covering an area of over 1,100 km2. It is the largest coastal lagoon in India and the largest brackish water lagoon in the world after The New Caledonian barrier reef.[6] It has been listed as a tentative UNESCO World Heritage site.

It is the largest wintering ground for migratory birds on the Indian sub-continent. The lake is home to a number of threatened species of plants and animals

The lake is an ecosystem with large fishery resources. It sustains more than 150,000 fisher–folk living in 132 villages on the shore and islands.

The lagoon hosts over 160 species of birds in the peak migratory season. Birds from as far as the Caspian Sea, Lake Baikal, Aral Sea and other remote parts of Russia, Kirghiz steppes of Kazakhstan, Central and southeast Asia, Ladakh and Himalayas come here. These birds travel great distances; some of them possibly travel as much as 12,000 km to reach Chilika Lake.

In 1981, Chilika Lake was designated the first Indian wetland of international importance under the Ramsar Convention.

According to a survey, 45 percent of the birds are terrestrial in nature, 32 percent are waterfowl, and 23 percent are waders. The lagoon is also home to 14 types of raptors. Around 152 rare and endangered Irrawaddy dolphins have also been reported. Plus, the lagoon supports about 37 species of reptiles and amphibians.

The highly productive Chilika Lagoon eco-system with its rich fishery resources sustains the livelihood for many fishermen who live in and near the lagoon. The water spread area of the lagoon ranges between 1165 and 906 km2 during the monsoon and summer respectively. A 32 km long, narrow, outer channel connects the lagoon to the Bay of Bengal, near the village Motto. More recently a new mouth has been opened by CDA which has brought a new lease of life to the lagoon.

Microalgae, marine seaweeds, sea grasses, fish and crab also flourish in the brackish water of the Chilika Lagoon. Especially the recovery of seagrass beds in recent years is a welcoming trend which may eventually result in re-colonization of endangered dugongs.
