Manipur, a state nestled in the northeastern corner of India, is blessed with a landscape of lush green valleys and serene hills. Adding to its natural beauty are a number of picturesque lakes, each with its own unique characteristics and charm. These lakes not only enhance the beauty of the state but also play a crucial role in the lives of the people, supporting their livelihoods and preserving the ecological balance.
Loktak Lake: The Jewel in Manipur's Crown
The most famous and largest freshwater lake in Manipur is Loktak Lake. Located in the Bishnupur district, Loktak Lake is unique for its "phumdis" – floating islands of vegetation, soil, and organic matter. These phumdis, varying in size, create a fascinating and dynamic landscape. The largest phumdi, covering an area of 40 sq km, is home to Keibul Lamjao National Park, the only floating national park in the world and the last natural refuge of the endangered Sangai (brow-antlered deer).
Loktak Lake is not only a visual treat but also a lifeline for the local communities. It is a source of water for irrigation, drinking, and fishing, and the phumdis are used for agriculture and housing. The lake also plays a crucial role in flood control and water regulation.
Other Notable Lakes in Manipur
While Loktak Lake is the most well-known, Manipur is home to several other lakes, each with its own unique features:
Pumlen Lake: The second largest lake in Manipur, Pumlen Lake is located in the Thoubal district. It is known for its scenic beauty and is a popular spot for boating and fishing.
Ikop Lake: Situated in the Thoubal district, Ikop Lake is a freshwater lake fed by the Arong River. It is known for its rich biodiversity and is an important habitat for various fish and bird species.
Waithou Lake: Located on the Indo-Myanmar Road, Waithou Lake is a popular tourist destination known for its serene environment and scenic beauty.
