In short: Chilika is the largest brackish lagoon on India's east coast, covering about 900 km2 in summer. It hosts over 225 bird species, a major winter wintering ground, and India's only known Irrawaddy dolphin population. Nalabana bird sanctuary needs a permit, and boats are the main way to see the lagoon.

Quick facts

Lagoon ecology

Salinity ranges from fresh near the Daya River mouth to about 42 ppt in the outlet channel in the dry season. This mix supports fish, birds and dolphins.

Birds and dolphins

Peak migration brings more than 160 species. Satapada is a common base for dolphin watching. Nalabana floods in the monsoon and reemerges afterward, when birds feed on its mudflats.

Visiting

Boats go from Satapada and other points; the lagoon is about 50 km from Puri. Choose licensed boatmen and ask them to keep distance from birds and dolphins. See wildlife photography ethics.
