The Origins of Chilika Lake – A Natural Creation Thousands of Years Old
Chilika Lake, located on the east coast of India in the state of Odisha, is more than just a water body — it’s a living history of geological transformation. Originally formed around 5,000 years ago, it is Asia’s largest brackish water lagoon. Moreover, multiple theories from experts like Hunter (1877), Blanfort, and Venkataramana (1970) suggest Chilika was once a part of the Bay of Bengal. Over time, it was gradually separated due to silt deposits and monsoon-driven sandbar formation.
Chilika on the Indian Map – Where Beauty Meets Geography
Chilika spans across Puri, Khordha, and Ganjam districts of Odisha. Geographically, it is shaped like a pear and stretches 64 km in length and 20 km in width. Interestingly, the lake covers around 1165 sq. km during the monsoon and shrinks to 906 sq. km in summer. Furthermore, it is positioned between 85°.5′ to 85°.35′ East longitude and 19°.28′ to 19°.54′ North latitude. Notably, the lagoon narrows as it approaches the Bay of Bengal at Satapada, yet it widens majestically near Rambha and Palur.
Exploring Chilika’s Island Network – The Hidden Jewels
Interestingly, Chilika boasts about 21 islands, grouped mainly into Parikud, Malud, and Satapada zones. Among these, the famous Kalijai Island, associated with folklore, and Nalabana, a bird sanctuary, are two major attractions. Additionally, each island holds a unique ecological or cultural story. Furthermore, while some islands like Mainsa-Berhampur lack basic facilities such as electricity, they still shine with raw, untouched beauty. Ultimately, these islands enhance the mystique and biodiversity of Chilika.
