Which is the largest freshwater lake in Northeast India?

Last Updated:

This question examines an important river-or-lake fact: “Which is the largest lake in Northeast India?” The correct answer is Loktak Lake. Loktak Lake in Manipur is the largest freshwater lake in Northeast India. The lake is famous for its Phumdis (floating islands of vegetation and soil) and the Keibul Lamjao National Park - the world's only floating national park. They may contain fresh, brackish or saline water, so terms such as lake, lagoon, reservoir and wetland should not be used interchangeably. Examination questions often confuse a river’s source with its mouth, a left-bank tributary with a right-bank tributary, or a natural lake with a reservoir.

Keibul Lamjao National Park, located on the lake’s floating landscape, is the natural habitat of the endangered Sangai deer. - Option A — Gurudongmar Lake: This is a high-altitude glacial lake in Sikkim, not the region’s largest freshwater lake. - Option C — Sone Beel: This is a major seasonal wetland in Assam’s Barak Valley. - Option D — Deepor Beel: This is a freshwater wetland near Guwahati and a Ramsar Site, but it is smaller than Loktak. Exam Takeaway: Loktak–Manipur–phumdis–Keibul Lamjao–Sangai is the key combination.
