Site description Son beel is a large lake in Karimganj district of southern Assam. It is flanked by hills on its west and east. In winter, the extent is only a few fragmented beels, totalling less than 500 ha. It is still the largest beel in Assam but it is being reduced (Choudhury 2000) and unfortunately, there is no conservation effort to save it. The Shingla River, originating in Mizoram, is its major inlet as well as outlet. Further downstream, there is another large lake known as Rata beel, beyond which the Shingla river bifurcates into two rivers Kochua and Kakra. Son beel is accessible from Hailakandi and Karimganj towns. Barringtonia acutangula is the main tree that grows in the beel besides reeds such as Arundo donax and various aquatic plants.
