The 'Chilika Lake', the largest brackish water lagoon in India, is situated at the mouth of which river deltaic formation?

💡 Solution & Explanation

Chilika Lake sits at the mouth of the Mahanadi River deltaic formation, forming the largest brackish water lagoon in Asia and supporting a rich biodiversity of aquatic life. Other river deltas like the Godavari or Kaveri do not host this specific coastal lagoon formation on the eastern seaboard of India. This wetland ecosystem was also designated as India's first Ramsar site in 1981.
