The largest wetland in Assam is Deepor Beel.
Deepor Beel is a permanent freshwater lake located on the south-western edge of Guwahati city. It is one of the most important wetlands in Northeast India and has been recognized as a Ramsar Site because of its rich biodiversity and ecological significance.
The wetland serves as a natural habitat for a large variety of migratory birds, fish species, and aquatic plants. It also plays a crucial role in maintaining the ecological balance of the region by acting as a natural stormwater reservoir and helping in flood control.
Thus, Deepor Beel is considered the largest and one of the most significant wetlands in Assam.
