Loktak Lake — at 287 sq km, India's largest freshwater lake — is famous for its extraordinary floating biomass islands called Phumdis: heterogeneous masses of vegetation, soil, and organic matter that float on the lake surface, varying in thickness from 2cm to 2m. On the largest phumdi mass lives the entire population of India's rarest deer — the Brow-antlered Deer (Sangai), also known as the Dancing Deer.
The Phumdi Ecosystem
Phumdis are unique to Loktak Lake — found nowhere else in the world at this scale. They form from dead organic matter (roots, stems, soil) accumulating over decades into floating platforms that support grasslands, shrubs, and even small trees. The largest contiguous phumdi — 40 sq km — has been designated Keibul Lamjao National Park, the world's only floating national park. It is the last natural refuge of the Sangai (Cervus eldi eldi), Manipur's state animal, with approximately 260 individuals.

The Sangai — The Dancing Deer
The Sangai (Rucervus eldii eldii) is India's most endangered deer and Manipur's cultural symbol — depicted on Manipuri traditional dress, dance, and crafts. It is called the "Dancing Deer" for its distinctive gait on the spongy phumdi surface. Once distributed across the Manipur valley, it is now entirely restricted to Keibul Lamjao. The population was as low as 14 in 1975 — strict protection since then has enabled its slow recovery. Boat trips to the edge of Keibul Lamjao NP offer the best viewing opportunities.
Lake Culture and the Fishing Communities
Over 100,000 people live on or around Loktak Lake, with many fishing communities living in huts built on phumdis — a floating village tradition that has existed for centuries. Traditional fish traps, circular cast nets, and the distinctive lake boats (dugout canoes and bamboo rafts) are the basis of the local economy. The fishing traditions of Loktak — multiple fishing techniques adapted to the phumdi ecosystem — constitute an extraordinary intangible cultural heritage. Phum Shang (floating hut settlements) communities welcome respectful visitors.
Getting to Loktak and Staying
Loktak Lake is 48km from Imphal (1.5 hours). Imphal is connected by daily flights from Kolkata, Delhi, and Guwahati. The Sendra Tourist Home on Sendra Island in the lake offers basic accommodation on the water — a genuine immersion experience. Entry permits to Keibul Lamjao NP are obtained from the park office at Khordak. Best time: October-February for Sangai sightings and migratory bird populations. The lake is a declared Ramsar Wetland of International Importance (1990).
Conclusion
Loktak Lake is one of India's most unusual and threatened ecosystems — its floating islands, dancing deer, and lake-dwelling communities form a system found nowhere else on Earth. Conservation of Loktak is simultaneously conservation of an ecological marvel and of the cultural identity of the Meitei people of Manipur.
